1
00:00:00,000 --> 00:00:00,160

2
00:00:00,160 --> 00:00:02,660
>> SPIKA 1: Sawa, hebu kuchukua
kuangalia jinsi ufumbuzi wafanyakazi kweli

3
00:00:02,660 --> 00:00:04,760
kazi, ili uweze
kupata hisia, kwanza mbali

4
00:00:04,760 --> 00:00:06,930
jinsi mtandao wa kompyuta walidhani
kukimbia, na jinsi gani unaweza kweli

5
00:00:06,930 --> 00:00:08,480
kupata mbio kwenye kompyuta yako mwenyewe.

6
00:00:08,480 --> 00:00:09,350
Hivyo picha yake hapa.

7
00:00:09,350 --> 00:00:13,640
Nimekuwa tayari imewekwa katika CS50 ID
pset6 nukta zip, kwa vipimo.

8
00:00:13,640 --> 00:00:16,197
Nimekuwa unzipped yake, na nimekuwa
CDed ndani ya pset6 saraka yangu.

9
00:00:16,197 --> 00:00:18,780
Moja ya mambo ya kwanza uko
atataka kufanya, hasa

10
00:00:18,780 --> 00:00:22,010
kama tumekuwa kutumia CS50 IDE ya kucheza
pamoja na mihadhara ya hivi karibuni, eti

11
00:00:22,010 --> 00:00:25,640
tumekuwa kutumia PHP katika
CS50 IDE, hasa,

12
00:00:25,640 --> 00:00:29,050
kutumia kwamba mtandao wa kompyuta inayoitwa Apache,
ambapo unaweza kuanza na kuacha ni

13
00:00:29,050 --> 00:00:30,910
na kwamba amri, Apache 50.

14
00:00:30,910 --> 00:00:34,160
Kwanza, kwenda mbele na
aina ya "Apache 50 stop"

15
00:00:34,160 --> 00:00:37,370
tu kuhakikisha kwamba kama ungekuwa
kufuatia pamoja katika siku za karibuni,

16
00:00:37,370 --> 00:00:40,090
na wewe akageuka juu Apache, uko
kugeuka kuwa mbali kwa njia hii

17
00:00:40,090 --> 00:00:41,360
na kuacha kompyuta.

18
00:00:41,360 --> 00:00:44,110
Sasa, nini mimi kwenda kufanya ni hasa
nini spec anasema mimi kufanya.

19
00:00:44,110 --> 00:00:49,770
Mimi nina kwenda kwa Tilda CS50 kufyeka
pset6 kufyeka server, na tu hit Enter.

20
00:00:49,770 --> 00:00:52,840
Utagundua kwamba mimi nina yelled saa
pamoja na baadhi ya maelezo ya matumizi, ambapo

21
00:00:52,840 --> 00:00:54,960
Mimi lazima mbio
Mpango kama server

22
00:00:54,960 --> 00:00:58,230
kwa hiari dash p na kisha
bandari idadi, ambayo unaweza kweli

23
00:00:58,230 --> 00:01:00,720
kuondoka tupu kwa sababu kwa
msingi, kwa spec,

24
00:01:00,720 --> 00:01:04,010
mtandao wa kompyuta ni kwenda
kudhani kuwa unataka bandari 8080.

25
00:01:04,010 --> 00:01:07,560
Wakati huo huo, unaweza kukumbuka kwamba
bandari 8080 ni kweli kiwango,

26
00:01:07,560 --> 00:01:09,380
badala bandari 80 ni
idadi tumekuwa aliyesema

27
00:01:09,380 --> 00:01:11,440
juu ya kuwa chaguo-msingi kwa HTTP.

28
00:01:11,440 --> 00:01:14,870
Naam, zinageuka kuwa CS50 IDE
ni tu kimeundwa kwa namna,

29
00:01:14,870 --> 00:01:18,730
kiasi kwamba wakati wewe na browser kujaribu
kutembelea bandari 80 kutoka dunia ya nje,

30
00:01:18,730 --> 00:01:22,210
itakuja kutatua ya magically
bandari mbele, au kuelekeza yenyewe,

31
00:01:22,210 --> 00:01:25,200
bandari 8080 ndani ya
Server yako yenyewe.

32
00:01:25,200 --> 00:01:29,330
>> Hivyo jambo la mwisho hapa ni amri
mstari hoja, njia ya njia.

33
00:01:29,330 --> 00:01:31,590
Na kwa kuwa mimi tu
maana, nini folder kufanya mimi

34
00:01:31,590 --> 00:01:34,820
nataka kukuambia server
kutumia kutumikia up mafaili?

35
00:01:34,820 --> 00:01:39,030
Kwa maneno mengine, kama ziara user
kufyeka, kile lazima yeye au yeye kuona kitu gani?

36
00:01:39,030 --> 00:01:41,030
Naam, hebu kwenda mbele na
kukimbia hasa kwamba tena,

37
00:01:41,030 --> 00:01:43,940
wakati huu kubainisha kwamba mimi
wanataka mizizi ya mtandao wa kompyuta yangu

38
00:01:43,940 --> 00:01:48,210
kuwa directory ya umma, kwamba anakuja
na tatizo kuweka usambazaji sita kanuni.

39
00:01:48,210 --> 00:01:50,620
Wakati mimi hit Enter, utaona
katika njano hapa, kukumbusha

40
00:01:50,620 --> 00:01:52,260
kama yale folder mimi nina kweli kwa kutumia.

41
00:01:52,260 --> 00:01:55,870
Katika kesi hiyo, ni kamba ya muda mrefu,
"nyumbani ubuntu workspace pset6 umma."

42
00:01:55,870 --> 00:01:57,500
Na neno hilo la mwisho ni nini muhimu.

43
00:01:57,500 --> 00:02:01,180
Na kisha mwisho, inaonekana, yangu
server ni sasa kusikiliza kwenye bandari 8080.

44
00:02:01,180 --> 00:02:05,860
>> Nini mimi ijayo kwenda kufanya wanakumbuka ni kwamba
katika CS50 ID kwa kona ya juu kulia

45
00:02:05,860 --> 00:02:09,440
ya screen yako, wewe ni kwenda kuona
URL kwamba ni ide50-username.cs50.io.

46
00:02:09,440 --> 00:02:12,860

47
00:02:12,860 --> 00:02:15,080
Na hakika, kama wewe click
kwamba, wewe utakuwa whisked mbali

48
00:02:15,080 --> 00:02:17,090
hadi nyingine tabo browser,
kwamba, katika kesi hii,

49
00:02:17,090 --> 00:02:20,830
ni kwenda kuonyesha mimi yaliyomo
yangu servrar mtandao mizizi.

50
00:02:20,830 --> 00:02:24,770
Kwa maneno mengine, mafaili unaweza kuona hapa,
paka nukta HTML, paka nukta JPEG, favicon nukta

51
00:02:24,770 --> 00:02:27,690
ico, hodi nukta HTML,
hodi nukta php, na mtihani,

52
00:02:27,690 --> 00:02:29,800
ni wote wa hiyo
yaliyomo kwamba ungependa kuona

53
00:02:29,800 --> 00:02:32,560
kwa LS ndani ya saraka yangu ya umma.

54
00:02:32,560 --> 00:02:36,790
Na nini ni nzuri ni kwamba kama mimi kwenda
mbele na bonyeza sasa juu ya paka nukta HTML,

55
00:02:36,790 --> 00:02:38,710
Mimi naona paka nukta HTML.

56
00:02:38,710 --> 00:02:42,660
Na kama mimi bonyeza paka nukta
JPEG, au hodi nukta HTML,

57
00:02:42,660 --> 00:02:46,650
au hata aina katika jina langu Daudi,
na kisha click "kusema hello,"

58
00:02:46,650 --> 00:02:49,420
utaona kwamba wote wa
mafaili kazi kwa sababu wafanyakazi

59
00:02:49,420 --> 00:02:52,820
ufumbuzi, bila shaka, imewekwa
katika CS50 ID ni kazi kikamilifu.

60
00:02:52,820 --> 00:02:57,090
Hivyo ni kazi hasa kama yako mwenyewe
ufumbuzi lazima hatimaye kazi.

61
00:02:57,090 --> 00:03:00,990
>> Wakati huo huo, kama sisi kurudi nyuma kwa wastaafu yangu
dirisha, ambapo mimi mbio amri server,

62
00:03:00,990 --> 00:03:03,410
taarifa ya nini console amekuwa akisema.

63
00:03:03,410 --> 00:03:07,890
Mimi naona hapa kwamba ombi la kwanza kwamba
Nilipata alikuwa literally kupata kufyeka paka

64
00:03:07,890 --> 00:03:10,260
dot HTML, HTTP toleo 1.1.

65
00:03:10,260 --> 00:03:12,600
Na kisha, katika kile kijani
ufumbuzi wafanyakazi amefanya

66
00:03:12,600 --> 00:03:14,580
ni ni kuonyesha mimi
mstari wa kwanza wa pato

67
00:03:14,580 --> 00:03:16,340
kwamba mtandao wa kompyuta ni kukabiliana na.

68
00:03:16,340 --> 00:03:18,300
Kwa maneno mengine, tumekuwa
tayari imeandikwa kificho

69
00:03:18,300 --> 00:03:21,530
kwamba kufungua kwamba bahasha virtual,
zenye kwamba ombi kupata.

70
00:03:21,530 --> 00:03:23,980
Na kisha sisi kukabiliana na
user lakini, wakati huo huo,

71
00:03:23,980 --> 00:03:28,780
magazeti kwa screen pato
hapa HTTP 1.1, 200 sawa

72
00:03:28,780 --> 00:03:31,900
kuthibitisha kile sisi ni kuweka katika
bahasha kurudi, hivyo kusema,

73
00:03:31,900 --> 00:03:33,540
kwamba sisi ni kutuma nyuma kwa mtumiaji.

74
00:03:33,540 --> 00:03:36,200
>> Na hivyo nini kinaendelea hapa ni
kwamba katika dirisha terminal,

75
00:03:36,200 --> 00:03:38,510
sisi ni mbio mtandao
server, na kwa hiyo, ni

76
00:03:38,510 --> 00:03:42,480
kusikiliza kwa HTTP
maombi juu ya TCP bandari 8080.

77
00:03:42,480 --> 00:03:44,960
Wakati huo huo, katika kivinjari changu,
kama mimi click kupitia kila

78
00:03:44,960 --> 00:03:48,480
ya mafaili hizo, au hata pembejeo yangu
jina Daudi, na kisha click Kuwasilisha,

79
00:03:48,480 --> 00:03:51,827
kuwa ni browser yangu
akizungumza na mtandao wa kompyuta.

80
00:03:51,827 --> 00:03:54,410
Na nini matendo mtandao wa kompyuta wa,
kisha, katika dirisha kwamba wastaafu

81
00:03:54,410 --> 00:03:56,370
ananionyeshea hasa
mstari wa kwanza hiyo ni

82
00:03:56,370 --> 00:03:58,540
kupokelewa katika virtual
bahasha na hasa

83
00:03:58,540 --> 00:04:02,870
mstari wa kwanza hiyo ni kuwa
alijibu kwa kwa kuwa mteja mtandao.
