00:00:00,000 --> 00:00:05,177

00:00:05,177 --> 00:00:07,010
DOUG LLOYD: Wakati mwingine
wakati sisi ni programu

3
00:00:07,010 --> 00:00:10,620
sisi kufanya mambo ya kawaida, hivyo
mara kwa mara, na hivyo watu wengi

4
00:00:10,620 --> 00:00:14,920
kufanya idea-- inayofanana au
Jambo, kwamba ina jina.

5
00:00:14,920 --> 00:00:16,780
MVC ni hasa mmoja kitu kama hicho.

6
00:00:16,780 --> 00:00:19,130
Ni wito programu dhana.

7
00:00:19,130 --> 00:00:21,830
Ni aina ya kama njia bora
ambayo yamekuwa distilled chini

8
00:00:21,830 --> 00:00:24,100
na watu kujaribu kufanya kitu.

9
00:00:24,100 --> 00:00:26,770
Katika kesi hiyo, kutekeleza
mfumo wa kurasa

10
00:00:26,770 --> 00:00:29,700
kwamba mtumiaji interacts na
kwenye tovuti ngumu zaidi.

11
00:00:29,700 --> 00:00:32,430
Na ni kosa hivyo kawaida kwamba
ni ilipendekeza kama kawaida

12
00:00:32,430 --> 00:00:35,721
kwamba watu wengine ili kama kufuata,
na kuna kuweka maalum sana ya njia

13
00:00:35,721 --> 00:00:37,500
kwamba mtu anaweza kufuata dhana hii.

14
00:00:37,500 --> 00:00:42,580
>> Hivyo, MVC ni dhana, na sababu
tunatumia ni kwa maelezo abstract mbali

15
00:00:42,580 --> 00:00:43,560
kutoka kwa mtumiaji.

16
00:00:43,560 --> 00:00:45,700
Baadhi ya mambo mtumiaji
kweli haina haja ya kuona.

17
00:00:45,700 --> 00:00:47,616
Wao wanataka tu kuwa na
nzuri user uzoefu,

18
00:00:47,616 --> 00:00:50,590
na hatuna haja ya kuwa nao
kupata kila faili moja kwamba

19
00:00:50,590 --> 00:00:52,750
ipo kwenye mtandao wetu server, labda.

20
00:00:52,750 --> 00:00:56,160
Huenda kuna baadhi ya files kwamba ni tu
kutumika kuimarisha uzoefu user,

21
00:00:56,160 --> 00:00:57,644
na hivyo tunaweza abstract wale mbali.

22
00:00:57,644 --> 00:01:00,060
Tunaweza aina ya kujificha yao ili
user hawawezi kufanya kazi pamoja nao,

23
00:01:00,060 --> 00:01:02,480
lakini pages-- yetu pages-- yetu
kujua jinsi ya kukabiliana nao

24
00:01:02,480 --> 00:01:05,840
na kuwaita au labda kuhitaji,
anataka yao, au kitu kama hicho.

25
00:01:05,840 --> 00:01:09,130
>> Motisha ya msingi
kwa MVC ni usalama wa data,

26
00:01:09,130 --> 00:01:12,415
kwa sababu MVC kawaida huja juu katika
mazingira ya kufanya kazi na database.

27
00:01:12,415 --> 00:01:14,480
Na katika sisi hasa
wanataka kuzuia watumiaji

28
00:01:14,480 --> 00:01:17,900
kutoka moja kwa moja athari database.

29
00:01:17,900 --> 00:01:21,520
Sisi tu unataka kufanya hivyo moja kwa moja,
kupitia filtration wetu.

30
00:01:21,520 --> 00:01:24,780
Au kuhakikisha kuwa kila kitu ni sawa na
sisi kufanya kidogo ya kuangalia makosa

31
00:01:24,780 --> 00:01:27,930
au proofing usalama kabla ya sisi
kutuma kwa Mbegu, ambapo

32
00:01:27,930 --> 00:01:32,850
mambo inaweza kwenda vibaya, labda
kweli vibaya, kama sisi siyo makini.

33
00:01:32,850 --> 00:01:35,630
>> Hivyo MVC anasimama kwa Model View Mdhibiti.

34
00:01:35,630 --> 00:01:36,870
Je, kila moja ya haya ina maana gani?

35
00:01:36,870 --> 00:01:38,742
Kimsingi, mfano ni orodha yako.

36
00:01:38,742 --> 00:01:40,700
Ni ambapo wote
taarifa muhimu kwa ajili ya tovuti yako

37
00:01:40,700 --> 00:01:42,790
majina ya watumiaji lives--, logins, nywila.

38
00:01:42,790 --> 00:01:46,400
Na unaweza taarifa hiyo, rejea yake,
kila kitu pretty much kama hicho.

39
00:01:46,400 --> 00:01:49,490
Wewe d swala database, utaweza kuomba
habari kutoka database.

40
00:01:49,490 --> 00:01:54,810
Hiyo ni model-- wote wa
data ambapo tovuti yako anaishi.

41
00:01:54,810 --> 00:01:57,930
>> Maoni ni aina ya kama
user uzoefu.

42
00:01:57,930 --> 00:02:02,090
Ni kurasa wanachokiona baada
wao kuwa ameomba habari.

43
00:02:02,090 --> 00:02:04,280
Hivyo labda wao kuwasilisha
kuingia yao information--

44
00:02:04,280 --> 00:02:07,280
ambayo watafanya katika mtawala,
ambayo tutaweza majadiliano juu katika pili.

45
00:02:07,280 --> 00:02:10,020
Wao labda kuwasilisha yao
Maelezo kuingia,

46
00:02:10,020 --> 00:02:12,320
na database ni aliuliza.

47
00:02:12,320 --> 00:02:16,489
Taarifa ni ombi na
vunjwa kutoka orodha.

48
00:02:16,489 --> 00:02:19,030
Na kisha mara moja mtumiaji watumiaji
katika, wanaona ukurasa wa nyumba zao.

49
00:02:19,030 --> 00:02:21,470
Hiyo ni maoni, sawa?

50
00:02:21,470 --> 00:02:24,655
>> Na kisha mtawala ni nini
aitwaye mantiki ya biashara ya tovuti yako.

51
00:02:24,655 --> 00:02:26,530
Na mantiki ya biashara ni
moja ya sheria hizo kuwa

52
00:02:26,530 --> 00:02:30,900
ni aina ya wishy-washy-- kama,
nini mantiki ya biashara na maana?

53
00:02:30,900 --> 00:02:33,650
Kimsingi biashara yako
mantiki ni PHP yako.

54
00:02:33,650 --> 00:02:36,260
User yako haina haja
kwa moja kwa moja kuona PHP yako,

55
00:02:36,260 --> 00:02:40,600
lakini PHP yako pengine ni nini kinaendelea
kuwa maamuzi maombi na database.

56
00:02:40,600 --> 00:02:43,310
>> Hivyo mtumiaji mapenzi pembejeo
habari katika mtazamo,

57
00:02:43,310 --> 00:02:46,120
ambayo itakuwa kuunganisha mtawala.

58
00:02:46,120 --> 00:02:48,130
Kama, wao itabidi aina katika fomu.

59
00:02:48,130 --> 00:02:50,910
Jinsi kwamba taratibu fomu
kampuni ni mtawala.

60
00:02:50,910 --> 00:02:55,159
Hiyo ni PHP hiyo ni kweli
kufanya ombi kwa mfano.

61
00:02:55,159 --> 00:02:57,200
Na kisha mfano inatoa
Maelezo ya maoni,

62
00:02:57,200 --> 00:03:00,540
ambayo inatoa ni kwa mtumiaji,
labda bora visualized kama ifuatavyo.

63
00:03:00,540 --> 00:03:01,240
>> Hivyo hapa sisi ni.

64
00:03:01,240 --> 00:03:05,760
Hapa ni yetu juu ya kushoto, na Model wetu
View Mdhibiti dhana utaratibu.

65
00:03:05,760 --> 00:03:06,810
Jinsi gani kazi?

66
00:03:06,810 --> 00:03:09,460
>> Us-- user-- hufanya
kuomba kwa mtawala.

67
00:03:09,460 --> 00:03:13,700
Sisi kuwasilisha taarifa
kama vile kwa namna HTTP.

68
00:03:13,700 --> 00:03:16,080
Kulingana na kwamba, mtawala wa
kazi ni kuhakikisha

69
00:03:16,080 --> 00:03:20,124
kwamba kile user amewapa si
kitu ambacho ingekuwa kuharibu mfano wa kuigwa.

70
00:03:20,124 --> 00:03:22,790
Na hivyo mtawala kinaendelea
kuhakikisha kwamba kila kitu ni sawa.

71
00:03:22,790 --> 00:03:23,720
Ni kwenda kuangalia kwa makini sana.

72
00:03:23,720 --> 00:03:27,030
Kama kuna makosa yoyote, kutakuwa na kuacha mambo
hivyo mtumiaji hawawezi kupata mfano wa kuigwa.

73
00:03:27,030 --> 00:03:29,470
>> Lakini kuchukua kila kitu
OK na ni swala halali,

74
00:03:29,470 --> 00:03:33,660
mtawala swala model--
kutakuwa na kuuliza ni kutoa taarifa.

75
00:03:33,660 --> 00:03:36,490
Mfano itatoa kwamba
Maelezo ya ukurasa hiyo ni maoni,

76
00:03:36,490 --> 00:03:39,150
kutakuwa na kusambaza ni kwamba
njia, na kisha mtazamo

77
00:03:39,150 --> 00:03:42,620
itakuwa na idadi ya maelezo
ombi kutoka mfano wa kuigwa.

78
00:03:42,620 --> 00:03:46,110
>> Hivyo, kwa mfano, kama tunazungumzia
kuhusu magogo katika ukurasa wako Facebook,

79
00:03:46,110 --> 00:03:46,870
kwa mfano.

80
00:03:46,870 --> 00:03:49,570
Mtazamo itakuwa data
waliotoka mfano kwamba

81
00:03:49,570 --> 00:03:52,070
inahusu rafiki yako na habari
kulisha au mambo kama hayo, haki?

82
00:03:52,070 --> 00:03:53,380
Lakini bila kuona mtu mwingine.

83
00:03:53,380 --> 00:03:55,088
>> Wewe d kuwa getting-- hivyo
kuwasilisha swala,

84
00:03:55,088 --> 00:03:59,400
wewe kuingia kwa kisingizio model--
mimi, wewe kuingia kwa ukurasa.

85
00:03:59,400 --> 00:04:01,240
Matumizi mtawala
Maelezo yako ya kuingia

86
00:04:01,240 --> 00:04:04,920
kufanya ombi kwa mfano kufanya
uhakika kuwa wewe ni nani kusema wewe ni.

87
00:04:04,920 --> 00:04:07,450
Mfano wa kama, sawa, ndiyo,
wewe ni nani kusema wewe ni,

88
00:04:07,450 --> 00:04:09,030
hivyo nikupe habari kulisha yako.

89
00:04:09,030 --> 00:04:11,730
Mimi nitakupa takwimu ghafi kwa
kulisha habari yako kwa mtazamo,

90
00:04:11,730 --> 00:04:14,063
na kisha mtazamo inafanya
warembo, michakato hivyo kwa njia

91
00:04:14,063 --> 00:04:17,560
kwamba sisi ni kutumika, kwa kuonyesha
kwamba taarifa kwa mtumiaji.

92
00:04:17,560 --> 00:04:20,579
>> Taarifa hiyo ni uhusiano
si zilizopo kwenye mchoro huu.

93
00:04:20,579 --> 00:04:24,750
Hakuna uhusiano wa moja
kati ya wewe na mfano.

94
00:04:24,750 --> 00:04:29,420
Kuna daima buffer hii ya
mtawala upande pembejeo,

95
00:04:29,420 --> 00:04:31,840
na kuna buffer ya
kuona upande pato.

96
00:04:31,840 --> 00:04:33,850
>> Labda wewe ni vizuri
mtu, na hivyo labda wewe

97
00:04:33,850 --> 00:04:36,310
bila kufanya uharibifu wowote kwa
mfano, lakini labda wewe si.

98
00:04:36,310 --> 00:04:38,990
Au labda kuna mtu ambaye ni
makusudi mtumiaji ambaye hakutaka labda

99
00:04:38,990 --> 00:04:42,640
wanataka kuharibu Mbegu yako, labda
kufuta kila kitu kutoka orodha yako,

100
00:04:42,640 --> 00:04:45,080
ambayo inaweza kuwa ghali sana.

101
00:04:45,080 --> 00:04:48,300
Ni wazi, kuwa user data is--
kuna thamani kwa kuwa data ya mtumiaji.

102
00:04:48,300 --> 00:04:53,290
Na hivyo kama hatukuwa kuweka buffer hii
zone kati ya mtumiaji na database--

103
00:04:53,290 --> 00:04:58,070
user na mambo model--
wanaweza kuwa kwenda vizuri kwa ajili yetu.

104
00:04:58,070 --> 00:05:00,232
>> Na hivyo ni muhimu kwa
na dhana hii ambapo

105
00:05:00,232 --> 00:05:03,440
user unaweza kuingiliana na Mbegu,
uhakika, lakini wao kwenda kupitia kwetu

106
00:05:03,440 --> 00:05:04,750
kufanya hivyo.

107
00:05:04,750 --> 00:05:06,530
Na kwamba kimsingi wazo na MVC.

108
00:05:06,530 --> 00:05:08,290
Ni kujaribu kutekeleza usalama wa data.

109
00:05:08,290 --> 00:05:13,130
Ni kujaribu kulinda mfano
kutoka inadvertently au kwa makusudi

110
00:05:13,130 --> 00:05:15,430
watumiaji hatarishi.

111
00:05:15,430 --> 00:05:17,392
>> Hivyo kile kinachotokea wakati
sisi kuomba dhana hii?

112
00:05:17,392 --> 00:05:19,850
Naam, sisi ni kutenganisha data
required kutoka website-- yetu

113
00:05:19,850 --> 00:05:23,320
model-- kutoka mantiki
kwamba zana tovuti yetu ya

114
00:05:23,320 --> 00:05:27,160
functionality-- controller-- na
kutoka aesthetics rahisi na ukurasa

115
00:05:27,160 --> 00:05:31,497
templates kuwa wanaunda yetu
user experience-- maoni.

116
00:05:31,497 --> 00:05:32,330
Hii ina maana gani?

117
00:05:32,330 --> 00:05:35,830
Vizuri, ina maana unaweza kufanya
maoni inayoonekana kwa mtumiaji.

118
00:05:35,830 --> 00:05:37,800
Unaweza kuficha mfano mbali.

119
00:05:37,800 --> 00:05:41,450
Na controllers-- mtumiaji
hawezi labda moja kwa moja kuendesha.

120
00:05:41,450 --> 00:05:43,230
Hawana haja ya kupata kanuni PHP yako.

121
00:05:43,230 --> 00:05:45,646
Wao tu haja ya kuona fomu
ambapo wanaweza aina ya mambo katika.

122
00:05:45,646 --> 00:05:47,605
Hivyo labda fomu ni
maoni, mtawala

123
00:05:47,605 --> 00:05:52,835
ni PHP kwamba fomu elekeza kwa,
mtawala hufanya swala mfano,

124
00:05:52,835 --> 00:05:55,210
mfano anatoa taarifa zaidi
kwa mtazamo tofauti kwamba

125
00:05:55,210 --> 00:05:57,400
maonyesho habari na wewe.

126
00:05:57,400 --> 00:05:59,640
>> Mipango wako wanaweza kupata
yote ya biashara mantiki yako,

127
00:05:59,640 --> 00:06:02,940
lakini watumiaji yako hawezi moja kwa moja
kupata mantiki ya biashara yako.

128
00:06:02,940 --> 00:06:07,600
Na moja hasa, pengine,
inayoonekana mfano wa hii

129
00:06:07,600 --> 00:06:11,370
ni wameweza milele kupokea
403 makosa Haramu.

130
00:06:11,370 --> 00:06:14,070
Je, umewahi kwenda kwa mtandao
ukurasa na kuonekana 403 Haramu?

131
00:06:14,070 --> 00:06:16,200
Ni aina ya kama 404 Haukupatikana.

132
00:06:16,200 --> 00:06:20,590
>> 403 Haramu ina maana alijaribu kupata
ukurasa kwamba huna upatikanaji wa.

133
00:06:20,590 --> 00:06:23,790
Labda tovuti ambayo ni
kutumia MVC kujitenga

134
00:06:23,790 --> 00:06:28,600
kujificha mbali biashara mantiki yake kwamba
inahitaji kuwepo kwenye kompyuta ili

135
00:06:28,600 --> 00:06:32,220
kwa ukurasa wa kufanya kazi, lakini hana
nataka wewe moja kwa moja kupata huduma hiyo.

136
00:06:32,220 --> 00:06:33,990
Hivyo unaweza kupata 403 Haramu makosa.

137
00:06:33,990 --> 00:06:36,073
>> Na bila hata jambo
kama ungekuwa umeingia.

138
00:06:36,073 --> 00:06:38,570
Hakuna mtumiaji anaweza kugusa hii nukta PHP faili.

139
00:06:38,570 --> 00:06:41,080
Wanaweza tu kugusa
hii moja, na one-- hii

140
00:06:41,080 --> 00:06:48,140
moja kwamba wanaweza touch-- labda
unaweza kuingiliana na imefungwa-chini faili

141
00:06:48,140 --> 00:06:52,330
moja kwa moja zaidi ya mtumiaji.

142
00:06:52,330 --> 00:06:57,610
>> Kwa hiyo, sisi wakati mwingine kuona ruhusa hii
makosa, hii 403 Haramu.

143
00:06:57,610 --> 00:07:01,360
Je, sisi mabadiliko ya ruhusa ili
kwamba mambo yanaweza au hauwezi kuonekana?

144
00:07:01,360 --> 00:07:06,910
Wakati sisi kufanya hivyo kwa kawaida ni kutumia
Linux amri inayoitwa chmod-- C-H-Mod.

145
00:07:06,910 --> 00:07:11,080
>> Kwa kufanya hivyo, muundo ni mzuri
simple-- chmod, ruhusa,

146
00:07:11,080 --> 00:07:13,710
na chochote faili unataka
kuomba kwamba mabadiliko ya.

147
00:07:13,710 --> 00:07:17,380
Kwa hiyo, labda utaweza kuona kitu
kama hii chmod 600 helpers.php.

148
00:07:17,380 --> 00:07:21,870
Au labda utaweza kuona Haya chmod
pamoja na x kuwa ni pamoja na directory.

149
00:07:21,870 --> 00:07:23,112
Ilikuwa Hii inamaanisha ingawa?

150
00:07:23,112 --> 00:07:25,570
Hivyo, kuna njia mbili tofauti
kwamba ruhusa ni kawaida

151
00:07:25,570 --> 00:07:26,920
kutumika kwa kutumia chmod.

152
00:07:26,920 --> 00:07:29,350
Kwanza inaitwa
octal idadi mbinu.

153
00:07:29,350 --> 00:07:32,160
Hii kwa kawaida inatumika ruhusa
kwa makundi matatu tofauti

154
00:07:32,160 --> 00:07:34,300
ya watumiaji kwa wakati mmoja.

155
00:07:34,300 --> 00:07:40,120
Hivyo chmod 711 faili ingeweza kuruhusu wewe
Haki ya kusoma, kuandika, na nitafanya

156
00:07:40,120 --> 00:07:43,050
file yako, ingeweza kuruhusu
others-- mahsusi

157
00:07:43,050 --> 00:07:46,469
kundi lako na world--
kwa tu nitafanya faili.

158
00:07:46,469 --> 00:07:47,760
Hiyo ni nini hii inasababisha na.

159
00:07:47,760 --> 00:07:50,150
Idadi ya kwanza huko
ni nini unaweza kufanya,

160
00:07:50,150 --> 00:07:52,370
idadi ya pili ni
nini kikundi anaweza kufanya,

161
00:07:52,370 --> 00:07:54,470
na wa tatu ni nini dunia anaweza kufanya.

162
00:07:54,470 --> 00:07:57,930
Mtu yeyote ambaye ni kutembelea yako
ukurasa, hiyo ni dunia.

163
00:07:57,930 --> 00:08:01,130
>> Je, ni namba hizi
kweli kutafsiri kwa ingawa?

164
00:08:01,130 --> 00:08:03,130
Basi hizi kimsingi kutafsiri kama hii.

165
00:08:03,130 --> 00:08:06,300
Kama ruhusa ni
sifuri, hakuna kinachoweza kutokea.

166
00:08:06,300 --> 00:08:10,239
Kama ni moja, unaweza kutekeleza
file-- kama hiyo idhini yako.

167
00:08:10,239 --> 00:08:13,030
Kama ni mbili, unaweza kuandika faili
lakini huwezi kufanya kitu kingine chochote.

168
00:08:13,030 --> 00:08:14,967
Kama ni tatu,
Unaweza kuandika na kutekeleza.

169
00:08:14,967 --> 00:08:16,050
Na kadhalika, kama unaweza kuona.

170
00:08:16,050 --> 00:08:19,320
Na saba ina maana unaweza kufanya kila kitu.

171
00:08:19,320 --> 00:08:21,760
>> Hivyo kwa nini ni hizi inaitwa idadi octal?

172
00:08:21,760 --> 00:08:24,537
Naam, kama wewe kufikiri juu yake,
hapa ni kama noes na yeses,

173
00:08:24,537 --> 00:08:26,620
na kama tunafikiri kuhusu wao
kama masanduku nyekundu na kijani,

174
00:08:26,620 --> 00:08:28,161
labda kwamba inafanya wazi kidogo.

175
00:08:28,161 --> 00:08:31,410
Lakini kama sisi kufikiri juu ya masanduku wale nyekundu
kama zeros na masanduku ya kijani kama zile,

176
00:08:31,410 --> 00:08:33,659
hizi ni kweli seti tu
ya idadi binary, sawa?

177
00:08:33,659 --> 00:08:42,510
000 inasababisha kwa decimal 0; 001,
alisema 1; 010 ni 2 alisema, na kadhalika.

178
00:08:42,510 --> 00:08:44,840
Na hivyo sisi kuwaita hawa octal
nambari kwa sababu kuna

179
00:08:44,840 --> 00:08:46,410
uwezekano nane tofauti.

180
00:08:46,410 --> 00:08:48,118
Kuna nane
tarakimu tofauti kama tuko

181
00:08:48,118 --> 00:08:50,220
kuzungumza juu tatu
vipande vya information--

182
00:08:50,220 --> 00:08:52,940
kusoma kidogo, kuandika
kidogo, na kutekeleza kidogo.

183
00:08:52,940 --> 00:08:56,910
Hivyo sasa unaweza kusema mapacha,
alisema, hex, na octal.

184
00:08:56,910 --> 00:09:00,250
Hivyo unajua jinsi ya kuwasiliana na
kompyuta katika nne idadi tofauti

185
00:09:00,250 --> 00:09:02,640
mifumo, hivyo hiyo ni pretty cool.

186
00:09:02,640 --> 00:09:05,200
>> Hivyo, badala ya octal
mpango ruhusa, kuna

187
00:09:05,200 --> 00:09:08,520
pia ruhusa ya mfano
mpango, ambayo ni tofauti kidogo

188
00:09:08,520 --> 00:09:13,290
na kwa kawaida hutumika bora kuomba au
kuondoa ruhusa katika bodi.

189
00:09:13,290 --> 00:09:17,070
Hivyo chmod pamoja na x faili
inaweza kuongeza haki

190
00:09:17,070 --> 00:09:20,270
kutekeleza kwa wote watatu
makundi ya users--

191
00:09:20,270 --> 00:09:22,890
mwenyewe, kundi lako, na ulimwengu.

192
00:09:22,890 --> 00:09:26,060
Pamoja na kwamba ni sehemu ya kuongeza.

193
00:09:26,060 --> 00:09:28,430
Haki ya kutekeleza, hiyo ni x.

194
00:09:28,430 --> 00:09:34,330
Na ukweli kwamba inatumika kwa wote
makundi matatu ya watumiaji itakuwa a.

195
00:09:34,330 --> 00:09:39,330
>> Hivyo Haya pamoja na x-- pengine ni kwenda
kuwa sawa kama chmod 711

196
00:09:39,330 --> 00:09:44,970
faili, kwa sababu kama wewe kurudi nyuma na
kuangalia octal idadi mpango,

197
00:09:44,970 --> 00:09:47,990
ndio na sevens kutupa
Haki ya kutekeleza faili.

198
00:09:47,990 --> 00:09:49,880
Hivyo hii pengine ni sawa.

199
00:09:49,880 --> 00:09:53,280
>> Na unaweza kutumia hii
rejea mwongozo kwa nini

200
00:09:53,280 --> 00:09:59,430
mambo mbalimbali katika
ishara chmod-ing muundo ni.

201
00:09:59,430 --> 00:10:03,522
Vitu ya kijani hapa itakuwa
ambapo kijani mfano yote rangi

202
00:10:03,522 --> 00:10:04,230
alikuwa wa pili iliyopita.

203
00:10:04,230 --> 00:10:05,740
Bluu itakuwa bluu.

204
00:10:05,740 --> 00:10:07,450
Machungwa itakuwa machungwa.

205
00:10:07,450 --> 00:10:10,360
Hivyo unaweza kuomba mambo ya yako
kundi, kwa wengine, kwa mtumiaji,

206
00:10:10,360 --> 00:10:11,510
au kwa kila mtu.

207
00:10:11,510 --> 00:10:13,670
Unaweza kuwapa kusoma,
kuandika, na nitafanya kupata,

208
00:10:13,670 --> 00:10:17,130
na unaweza kuongeza au kuondoa
au hawawajui hasa kuweka

209
00:10:17,130 --> 00:10:20,310
ya ruhusa kwa kutumia mtindo huu.

210
00:10:20,310 --> 00:10:22,530
>> Je, sisi kuangalia nini
Mpango faili ruhusa ni?

211
00:10:22,530 --> 00:10:25,770
Kabla ya mabadiliko hayo, ni
pengine nzuri ya kweli kujua

212
00:10:25,770 --> 00:10:27,800
nini ruhusa faili ni.

213
00:10:27,800 --> 00:10:31,370
Njia moja ya kufanya hivyo ni kukimbia ls
lakini tu tweak ni kidogo.

214
00:10:31,370 --> 00:10:35,570
Hivyo kama mimi aina ls dash l--
hiyo ni ndogo l-- labda

215
00:10:35,570 --> 00:10:36,870
Mimi utaona kitu kama hiki.

216
00:10:36,870 --> 00:10:39,490
Inaonekana kidogo cryptic, lakini
sehemu kwamba sisi kweli huduma kuhusu

217
00:10:39,490 --> 00:10:41,000
ni mambo upande wa kushoto zaidi ya hapo.

218
00:10:41,000 --> 00:10:43,380
Kwamba kweli bayana
Mpango faili ruhusa.

219
00:10:43,380 --> 00:10:47,470
Na pengine unaweza kusema kwa sababu ni
got r wa, w, na x ya Kukifuatiwa.

220
00:10:47,470 --> 00:10:49,750
>> Wale three-- kwanza
kupuuza moja kwanza

221
00:10:49,750 --> 00:10:51,870
kwa ajili ya pili, ambayo
tutaweza mara mbili nyuma ya.

222
00:10:51,870 --> 00:10:54,080
Wale wa kwanza tatu baada ya
first-- hivyo wa pili,

223
00:10:54,080 --> 00:10:56,700
tatu, na wahusika wa nne
ya kwamba kamba 10 tabia

224
00:10:56,700 --> 00:10:59,150
ni ruhusa kwamba una.

225
00:10:59,150 --> 00:11:02,390
Hivyo inaonekana siwezi kusoma,
kuandika, na nitafanya PHP.

226
00:11:02,390 --> 00:11:04,870
Siwezi kusoma, kuandika, na
kutekeleza PHP WebDev,

227
00:11:04,870 --> 00:11:07,786
na ninaweza kusoma na kuandika test.php.

228
00:11:07,786 --> 00:11:11,020
>> Kundi yangu unaweza kufanya hivyo.

229
00:11:11,020 --> 00:11:14,960
Hivyo inaonekana na PHP
na PHP WebDev directories,

230
00:11:14,960 --> 00:11:18,330
kundi yangu unaweza kuandika kwa
nao lakini kitu kingine.

231
00:11:18,330 --> 00:11:20,210
Na dunia hawezi kufanya kitu chochote.

232
00:11:20,210 --> 00:11:22,115
Hivyo mafaili haya si
hadharani kupatikana

233
00:11:22,115 --> 00:11:23,990
na kama mimi walijaribu
kuzipata na sikuwa

234
00:11:23,990 --> 00:11:29,160
mbio Apache ili kuwafanya kupatikana,
basi napenda kupata 403 makosa.

235
00:11:29,160 --> 00:11:29,950
Ni kushindwa.

236
00:11:29,950 --> 00:11:32,916
Nilijaribu kupata faili lakini mimi
hawana ruhusa ya kufanya hivyo.

237
00:11:32,916 --> 00:11:34,290
Na nini hicho tabia ya kwanza?

238
00:11:34,290 --> 00:11:39,120
Naam, pengine unaweza extrapolate
hapa kwamba d's rejea directories

239
00:11:39,120 --> 00:11:42,080
na dash inahusu
kinachojulikana "mara kwa mara mafaili."

240
00:11:42,080 --> 00:11:45,430
Na labda wameweza kuona hii wakati wewe wameweza
alijaribu kuondoa faili kwa kutumia rm.

241
00:11:45,430 --> 00:11:49,310
Wameweza kuona ujumbe cryptic
"kuondoa faili mara kwa mara" - katika kesi hii,

242
00:11:49,310 --> 00:11:51,020
d kuwa test.php.

243
00:11:51,020 --> 00:11:53,900
Mara kwa mara file ni tu kitu
si kwamba directory.

244
00:11:53,900 --> 00:11:56,191
Kuna michache ya wengine
hapa, lakini kwa ujumla uko

245
00:11:56,191 --> 00:11:59,179
kwenda kuona d's kwa directories
na chochote kwa kipengele kwanza.

246
00:11:59,179 --> 00:12:00,720
Lakini hiyo ni kweli wote kuna hiyo.

247
00:12:00,720 --> 00:12:03,210
Unaweza kuangalia faili
ruhusa kutumia ls dash l,

248
00:12:03,210 --> 00:12:05,100
unaweza mabadiliko yao kwa kutumia chmod.

249
00:12:05,100 --> 00:12:09,430
Na, bila shaka, kutumia these--
kubadilisha ruhusa

250
00:12:09,430 --> 00:12:14,180
kutekeleza hii dhana MVC kwa
kulinda data kwenye tovuti yako

251
00:12:14,180 --> 00:12:16,180
na si kuruhusu watumiaji
kupata kila kitu,

252
00:12:16,180 --> 00:12:19,120
lakini tu mambo ambayo wanahitaji
kupata ili kwa ukurasa wako

253
00:12:19,120 --> 00:12:22,110
kufanya kazi kwa njia unataka kufanya kazi.

254
00:12:22,110 --> 00:12:23,040
>> Mimi nina Doug Lloyd.

255
00:12:23,040 --> 00:12:24,880
Hii ni CS50.

256
00:12:24,880 --> 00:12:27,286
