00:00:00,000 --> 00:00:00,430

2
00:00:00,430 --> 00:00:03,260
>> SPIKA 1: Hebu kutekeleza search
injini au, angalau, frontend user

3
00:00:03,260 --> 00:00:06,590
interface kwa ajili ya kutafuta injini kwamba
inaruhusu mtumiaji aina katika baadhi ya maneno

4
00:00:06,590 --> 00:00:09,370
na kisha kutafuta duniani kote
mtandao kwa ajili ya sheria hizo.

5
00:00:09,370 --> 00:00:13,690
Ili kufanikisha hili, tutaweza kutumia "mfumo" HTML ya
tag, kama vile wengine wachache.

6
00:00:13,690 --> 00:00:17,140
Hapa katika Search.html, nimekuwa tayari
kujipatia yetu ilianza na ufunguzi na

7
00:00:17,140 --> 00:00:18,500
kufunga vitambulisho chache.

8
00:00:18,500 --> 00:00:22,570
Hivyo sasa hapa, ndani ya mwili huu, hebu
kwanza kufafanua kichwa cha CS50

9
00:00:22,570 --> 00:00:26,460
Kutafuta na kutumika kama jina la aina
katika mwili wa ukurasa.

10
00:00:26,460 --> 00:00:30,660
>> Hebu kisha kufungua "mfumo" tag, na
preemptively, hebu karibu, hivyo si

11
00:00:30,660 --> 00:00:31,930
kusahau baadaye.

12
00:00:31,930 --> 00:00:37,450
Hebu kisha kufafanua pembejeo tag, ambao
jina lake ni "q" kwa ajili ya swala, na ambao

13
00:00:37,450 --> 00:00:40,810
aina litakuwa "maandishi," ili
kisakuzi mithili ya hii kama ya maandishi

14
00:00:40,810 --> 00:00:41,840
juu ya ukurasa.

15
00:00:41,840 --> 00:00:43,720
Hebu basi karibu tag hii.

16
00:00:43,720 --> 00:00:46,480
Hebu kisha kuingiza line mapumziko chini.

17
00:00:46,480 --> 00:00:50,870
Na hebu sasa kufafanua zaidi pembejeo moja hii
wakati, ambaye aina itakuwa kuwasilisha,

18
00:00:50,870 --> 00:00:56,640
hivyo kwamba Kuwasilisha kifungo, na ambao
thamani au studio ni CS50 Search.

19
00:00:56,640 --> 00:00:59,930
>> Sasa tumekuwa inavyoelezwa fomu hii, lakini sisi
si maalum kwa ambapo fomu

20
00:00:59,930 --> 00:01:01,120
lazima kuwasilishwa.

21
00:01:01,120 --> 00:01:04,480
Hebu kuongeza sifa mbili zaidi
kuwa sahihi zaidi hapa.

22
00:01:04,480 --> 00:01:09,410
Kwanza, hebu taja katika "mfumo" tag
yenyewe kwamba mbinu ambayo hii

23
00:01:09,410 --> 00:01:12,620
aina lazima kuwasilishwa ni HTTP kupata.

24
00:01:12,620 --> 00:01:16,150
Na hebu bayana kwamba hatua au
marudio ya aina hii itakuwa

25
00:01:16,150 --> 00:01:22,540
https://www.google.com/search.

26
00:01:22,540 --> 00:01:25,690
>> Sasa, najua kwamba URL lipo kwa sababu
Nimeona ni kwa baadhi ya wakati katika wangu

27
00:01:25,690 --> 00:01:27,080
browser anwani bar.

28
00:01:27,080 --> 00:01:32,020
Hivyo mimi nina tu kwenda kwa kutaja mtumiaji
kwamba URL kwa matokeo yao search.

29
00:01:32,020 --> 00:01:35,380
Hebu sasa ila, mabadiliko ya ruhusa
juu, na kufungua hatua hii.

30
00:01:35,380 --> 00:01:41,090
"Chmod pamoja na r search.html."
Hebu sasa kufungua Chrome.

31
00:01:41,090 --> 00:01:46,770
http://localhost/search.html.

32
00:01:46,770 --> 00:01:49,345
Si sexiest ya injini ya utafutaji,
lakini hebu angalia kama ni kazi.

33
00:01:49,345 --> 00:01:51,920

34
00:01:51,920 --> 00:01:53,240
Na kuna baadhi ya paka.

35
00:01:53,240 --> 00:01:57,140
>> Taarifa ingawa, kuliko katika bar anwani
ni hasa URL kwamba mimi ilivyotarajiwa,

36
00:01:57,140 --> 00:01:58,910
lakini kwa kitu kidogo
zaidi mwishoni.

37
00:01:58,910 --> 00:02:04,260
Kama mimi kuvuta hapa, taarifa kwamba URL
ni hasa kama sisi ilivyotarajiwa, lakini kwa

38
00:02:04,260 --> 00:02:07,260
swali q usawa
paka juu.

39
00:02:07,260 --> 00:02:08,729
Wapi kwamba kuja kutoka?

40
00:02:08,729 --> 00:02:12,880
>> Naam, kwa sababu mimi in fomu kuwa
alikuwa na mchango wa, jina lake q, yetu

41
00:02:12,880 --> 00:02:16,300
kisakuzi alichukua juu yake yenyewe na kuongeza kwamba
swali alama na kisha kuweka kwamba

42
00:02:16,300 --> 00:02:17,820
jina parameter ya - q -

43
00:02:17,820 --> 00:02:21,130
ikifuatiwa na ishara sawa, ikifuatiwa
na paka, ambayo ni thamani ya kuwa mimi

44
00:02:21,130 --> 00:02:22,550
mwenyewe typed in

45
00:02:22,550 --> 00:02:26,130
Kama kulikuwa na zaidi vigezo kama
ndani ya URL, browser ingekuwa

46
00:02:26,130 --> 00:02:28,500
kuwa tu kutengwa
yao kwa Ampersand.

47
00:02:28,500 --> 00:02:30,790
Lakini katika kesi hii, tuna
moja tu kama jozi.

48
00:02:30,790 --> 00:02:35,040
Na kwamba ni zinazotolewa kama pembejeo kwa
Google sana kama parameter ni

49
00:02:35,040 --> 00:02:37,000
zinazotolewa na kazi ni pembejeo.

50
00:02:37,000 --> 00:02:40,600
Na Google basi anatumia pembejeo kwamba kwa
kutafuta database yake kwa namna fulani na

51
00:02:40,600 --> 00:02:42,180
kuonyesha ukurasa wa matokeo.
