Siye sifunde kunye yintoni 'script'

mba uya kusonjululwa kule ncwadi ukuba "script." Emva kokufunda eli lwazi, abafundi baya kufumana ngamagqabantshintshi iinkqubo zomsebenzi. Baya kwenzelwa eminye imiyalelo eluncedo ngalo mbandela. Ngoko ke, i "zeempendulo" - kukuthi, kuqala, iinkqubo okanye iifayile program, izikripthi. Enyanisweni, lo gama libhekisela nayiphi na inkqubo ephunyeziweyo.

"Izikripthi" Programs- abe kunomda nangakumbi mbono. Umzekelo, ubugcisa esekelwe kwi-Internet iintsingiselo zilandelayo elithi: "Le nkqubo ephunyeziweyo sokusebenzisa umncedisi kwi isicelo esithile, oluphuma iphepha ethile (resource Web) ye Internet." Ukuthetha ngento i "script 'ngokubhekiselele kwisicelo yayo, oko kufuneka kucaciswe ukuba imihlaba ukusetyenziswa kweenkqubo ezinjalo liphezulu.

Ngoncedo lwabo, ikhompyutha siqu, umsebenzisi akanokukwazi libhekisele iindidi zedata, iyakwazi esweni manani Utyelelo zokubala ezizodwa. Kwakhona, oku kubandakanya izimvo Ndiyahamba iincwadi ezithile, ukusebenza kunye neencwadi eendwendwe (ngokwenza izicelo iirekhodi), njalo-njalo. Uphi na ke "script '? indawo yayo inokuba efanayo umncedisi elibamba iphepha Web elibhekisele kuyo. Kuyenzeka ukuba indawo yayo, njengomncedisi Intanethi ekude.

Ngenxa yokuba bekusungulwa "script" wenza amanyathelo ezithile kufuneka kuthathwe ukuba uqaphele ukuba ukuphunyezwa kweenkqubo ezinjalo zingaba luncedo kwaye kuyingozi. Ngokukodwa, oko kube nengozi ezithile abanini umncedisi. Ngako oko, inxenye kubo, musa ukusebenzisa "zeempendulo". Ngokuqhelekileyo, umboneleli inikela eli phawu emva kokuba iimeko ezithile nekayo isicelo ezi nkqubo.

Ngoku makhe sithethe yintoni i "script", yaye isicelo yayo ngakumbi. Enyanisweni, ke ngoku kusetyenziswa zonke resource web, yaye uyazi ngazo okanye uve naziphi umsebenzisi PC ngaphezulu okanye ngaphantsi phambili. Kunokwenzeka ukuba ngexesha elifanayo eninzi yabantu yayifuna ukwazi malunga imbonakalo kunye nokusebenza le nkqubo. Siza kuthetha ntoni "script-ubulalelale", nto leyo eneneni iprogram eyehlayo on server Web.

Nokuba isebenza, ngokulandelelana, emva abathengi isicelo. Phantsi ngumthengi apha akubhekiselwanga Iindwendwe ezithile ze-sites Web. Enyanisweni, "ubulalelale-elishicilelwe" ngendlela efanayo kwezinye iinkqubo zekhompyutha, ezifana "Ward" (MS Word) okanye "Explorer" (Explorer). Ekuqaleni, kufuneka kuqondwe ukuba "ubulalelale" asiyiyo uhlobo ulwimi lokuprograma, kunye ezo "zeempendulo" ebhaliweyo. Igama elipheleleyo le yekhompyutha ezizodwa - "Common Gateway Interface". Isetyenziswa ukuba usebenzise i 'zeempendulo "kunye nokuqhuba umsebenzi ngakumbi.

Ke kaloku, emva ingxelo eyenziwe ngaphambili: ". Ukwenza iinkqubo ezichazwe ukuze athwale ingozi" Ke ukuba i "CGI-zeempendulo", ngoko ke akukho ngaphandle. Oku kuthetha ukuba izicwangciso ezithile-iiprojekthi Internet kufuneka ukhankanye iinkcukacha ukuphunyezwa "CGI" kwi server ethile. Yathi ngaphambili ukuba ezinye ibamba ababoneleli ngeenkonzo intanethi kuphela okanye kuthintelwe ekwenzeni iinkqubo ezinjalo.

Amaxesha amaninzi imiqathango ekusetyenzisweni kwe "CGI" kwenziwa ukusingathwa free. Oku kukhokelela ekubeni lomsebenzisi, ndayihluthwa ithuba ukuqonda iintlobo eluncedo.

Ezi nkcukacha of "script-CGI": Ukuba unguye umnini-web resource, ngoko hamba uye iindwendwe zakho kwisayithi ngubani upose ncomo, izimvo. Ngelo xesha linye gcwalisa imihlaba eyiyo, kwaye ngoku nqakraza - "Thumela". Emva kwezi zazo idata uthunyelwa kumncedisi, kukho ukuphehlelelwa "ubulalelale-elishicilelwe" kunye processing ulwazi. A ndwendwe ngexesha elifanayo ebona ukuba izimvo zakhe kuvela kwiphepha uze ufumane umyalezo ezifana: "! Izimvo zakho longeziwe, enkosi"

Enyanisweni, uluvo jikelele yintoni "umbhalo", nina ngoku. Ukuze isifundo ngokucokisekileyo ngakumbi, kukho ezikhethekileyo ngezixhobo zokuqeqesha umxholo.
