I-curl ayikwazi ukufunda ifayela lakho le-PAC: dlulisa i-proxy esikhundleni
I-PAC iyinqubomgomo ye-JavaScript; i-curl ifuna indawo yokugcina. Buza ukuthi iyiphi i-proxy inqubomgomo eyikhethayo ku-URL yakho, yidlulise, futhi ubheke i-NO_PROXY ne-TLS.
Ikheli lefayela le-PAC nendawo yokugcina ye-proxy kubonakala kungashintshana kufayela lokuhlela, futhi akunjalo. Eyokuqala iwuhlelo lwenqubomgomo okufanele luhlolwe ku-URL ngayinye; eyesibili iyihost ne-port emukela ukuxhumana. I-curl iqonda eyesibili kuphela. Ukudlulisa ikheli le-PAC ku- --proxy kuyiphutha lesigaba elihluleka ngendlela edidayo, ngokuvamile ngemva kwesikhathi eside se-CONNECT esiya kuseva yewebhu.
Yini ngayinye ngempela
| Una nayo | Iyini | I-curl yenzani ngayo |
|---|---|---|
http://wpad.corp.example/proxy.pac | I-JavaScript ebuyisela i-proxy noma ukuxhumana okuqondile kwe-URL ethile | Iyilanda njengefayela bese ima lapho |
http://proxy.corp.example:8080 | Isilaleli esamukela izicelo ezidlula ku-proxy | Iyisebenzisa, kuhlanganise ne-CONNECT kumaphuzu e-HTTPS |
Lokhu kushiwo ngokucacile imibuzo evamile nge-curl: i-curl ayinikezi ncazelo ye-JavaScript noma ye-PAC. Isembozo esizungeze i-curl esiqonda i-PAC singakwenza, kodwa i-curl uqobo ayikwenzi, futhi akukho flag eyenza ibe isiphequluli.
Kungani isiphequluli sisebenza kanti i-curl ayisebenzi
Isiphequluli sihlangana nokuhlelwa kwe-proxy kwesistimu, silanda ifayela le-PAC futhi sisebenzisa imithetho yalo ku-URL oyivulayo. Lokho kuhlola iyisevisi enikezwa ifayela le-PAC, futhi kwenzeka ngaphakathi kwesiphequluli, hhayi ngaphakathi kwethemineli lakho.
Ukulanda ifayela le-PAC nge-curl kuthola umbhalo walo kuphela. Akwenzi i-curl isebenzise inqubomgomo, futhi ukulifunda ngesandla ukuze uthole i-proxy kuyinguqulo yesandla yalokho kuhlola, namathuba afanayo okukhetha igatsha elingalungile. Uma ulifunda, funda isitatimende se-return esihambisana nehost yakho esikhundleni segama lokuqala le-proxy efayeleni. Iningi lamafayela e-PAC liqukethe amaningi, futhi igatsha elilodwa kuphela elisebenza kuwe.
Kwi-proxy ye-HTTP egunyaziwe kanye nesisevisi se-HTTPS esigunyaziwe, isicelo esiyisibonelo yilesi:
curl --proxy http://proxy.corp.example:8080 https://service.example.net/statusIkheli lokuqala isilaleli se-proxy, elesibili isisevisi osifunayo. Lezi ziyizindawo zokugcina eziyisibonelo hhayi ukuhlolwa okwenziwe umuntu, ngakho shintsha ngesikimu, i-port kanye nokugeleza kokuqinisekisa kwesikhungo sakho.
Khetha i-proxy yale ndawo oya kuyo
Buza umphathi ukuthi iyiphi i-proxy inqubomgomo eyikhethayo ku-URL oyidingayo, hhayi ukuthi iyiphi i-proxy ephethwe isikhungo. Imithetho ye-PAC ingabuyisela imiphumela ehlukene kumasevisi angaphakathi, kumasayithi omphakathi nasezimeni zokushintsha uma kwehluleka, futhi umthetho ohambisana ne-URL yakho namuhla ungahambisana nomunye ngemva kokuhlela.
Uma ukugeleza komsebenzi kudinga izicelo ezingaphezu kwesisodwa ezaziwayo, sebenzisa isilungiselelo esimile esisekelwa umphathi noma ukuhlanganiswa okuvunyiwe okuqonda i-PAC. Ukubhala ngokuqinile ikheli elilodwa elikopishiwe kusebenza kuze kufike usuku lapho inqubomgomo ishintsha khona futhi akekho osakhumbula ukuthi kungani lelo kheli lakhethwa.
Bese ubheka ukuthi i-curl ifa ini. Iziguquli zemvelo ze-proxy kanye ne- NO_PROXY kungase kudlule noma kukhiphe i-proxy oyidlulisile, futhi ukukhipha okuhambisana nomgomo wakho kuthumela isicelo ngqo buthule. Gcina inqubomgomo ehlosiwe esikhundleni sokususa konke ukukhipha noma ukuphoqa konke kudlule ekhelini elilodwa. Sebenzisa isicelo kanye nge- -v bese uhlola ukuthi saxhumana nakhiphi ikheli ngempela.
Gcina ubunikazi be-TLS ababili buhlukene
Nge-proxy ye-HTTPS, kukhona ukuxhumana kwe-TLS okubili okusebenzayo: okwakho okuya ku-proxy nokwe-proxy okuya endaweni oya kuyo. Ngakunye kunobunikazi bakho obufanele buqinisekiswe, futhi ukucisha ukuqinisekisa kunoma yikuphi kwazo akulona ukulungisa kwe-PAC, kuyinkinga yesibili eyengezwe kweyokuqala.
Shiya ukuqinisekisa kuvuliwe futhi ufunde ukwehluleka okutholayo. Inselelo yokuqinisekisa ye-proxy, i-proxy engafinyeleleki kanye nokwenqaba kwesayithi kuyimiphumela emithathu ehlukene, futhi eyokuqala kuphela ephathelene nezicucu zokungena. I-VPN kusafanele inikeze indlela evunyelwe eya ku-proxy yangasese, kuhlanganise nokuxazululwa kwamagama kwehost ye-proxy uqobo, ngaphambi kokuba noma yikuphi kwalokhu kuphumelele.
Bhala phansi indawo yokugcina, isikimu, i-port, indlela yokuqinisekisa, ukukhipha kanye nomzila we-VPN oya ku-proxy. Lowo mbhalo yiwona owenza isicelo esilandelayo siphinda senzeke, futhi yiwo umehluko phakathi kokwazi i-proxy yakho nokuqagela ngayo.
