Yiziphi-HTTP-iphutha?

Abasebenzisi be-intanethi ukuthi kukhona kancane shí amagama we-Web (okungenani iningi lazo), ukwazi ukuthi umthetho olandelwayo we-HTTP. Lesi sivumelwano ukudluliswa kwedatha ivumela abasebenzisi bahlangane izinsiza kwiwebhu usebenzisa isiphequluli. Omunye nemisebenzi olandelwayo yikhono ukubuyela amakhodi ekhethekile ukunikeza abasebenzisi ngolwazi ngesimo website noma isimo ukuqaliswa umsebenzi inikezwe. Lihlanganisa futhi iphutha le-HTTP amakhodi. Amakhodi iphutha zihlukaniswe izinhlobo ezimbili: iklayenti amaphutha kanye iseva amaphutha. On lezi zigaba ezimbili, kanye nezinye ewusizo, futhi okubaluleke - amakhodi ezivamile okuxoxwe ngazo kulesi impahla.

Iphutha le-HTTP-iklayenti

Uma iphutha itholiwe ohlangothini iklayenti, iseva ibuyisela ikhodi ekilasini 4xx yakhe. Uma iseva ayitholakalanga izinkinga, kodwa namanje akutholakali umsebenzisi, iklayenti ithunyelwa ikhodi unencazelo ngephutha.

Ngakho, ikhasimende ikhodi yephutha ngaphansi 40s:

• 400. Isicelo esingavumelekile - nephutha kwenzeka uma iseva ubona le-syntax esicelweni kusukela iklayenti. It kuzokwenzeka nje ohlangothini iklayenti akulona ushintsho olufanele zizokwenziwa. Kufanele athobele yonke imithetho ukudlulisa idatha olandelwayo osetshenziswa.
• 401. Akukho ukugunyazwa - Leli phutha ibonisa ukuthi i-HTTP-iseva idinga ubuqiniso. Ngesikhathi esifanayo kuba ohlangothini iseva beze bonke izimo ukwenza ubuqiniso. Imbangela yale iphutha kungenzeka igama elingalungile noma iphasiwedi ukuqinisekiswa.
• 402. Kuyadingeka ukhokhe imali - ikhodi alisetshenziswa, kodwa Ligcinelwe nina olandelwayo lekusasa. Ekuqaleni wazalwa interface ezimenze wangakwazi ukukhokha ukufinyelela umthombo ethile. Njengoba ayisebenzanga, ikhodi 402 sebemukele-Google ne-Apple, ngezikhathi ezithile ukuze silisebenzise amasevisi abo web.
