Khaladaadka proxy ee 502 Bad Gateway: ogow cidda soo dirtay

Updated:

502 Bad Gateway waxay ka dhigan tahay in server dhexe, oo noqon kara proxy-gaaga ama server-ka hore ee website-ka laftiisa, uu gudbiyay codsiga balse uusan helin jawaab sax ah oo soo noqotay. Waa isla lambarkii, laakiin laba sababood oo aad u kala duwan, markaa intaadan waxba hagaajin ka hor ogow cidda soo celinaysa 502.

Sida uu u eg yahay 502 ka yimid proxy-ga

Waxaan ka dhignay in proxy-geenna tijaabada ah uu bixiyo jawaabta 502 waxaana duubnay jawaabaha, iyadoo dib loogu qoray 203.0.113.10:8080 iyo user123:pass456:

  • Website HTTPS ah: curl -x http://user123:[email protected]:8080 https://example.com wuxuu soo daabacayaa curl: (56) CONNECT tunnel failed, response 502.
  • Website HTTP caadi ah: curl wuxuu helayaa xaaladda 502.
  • Chrome marka uu bog HTTPS ah ku furayo proxy-gaas wuxuu soo sheegayaa ERR_TUNNEL_CONNECTION_FAILED mana muujinayo wax bog 502 ah haba yaraatee.
  • Qalabka hubinta proxy-ga wuxuu muujinayaa HTTP 502; koodhadhka kale waxay u muuqdaan si la mid ah sida HTTP <code>.

Astaanta lagu garto: bog 502 ah oo ku yaal website HTTPS ah

Website-yada HTTPS, proxy-gu wuxuu kaliya furaa tunnel; ma gelin karo bog u gaar ah gudaha xiriir qarsoodi ah. Haddii proxy-gu diido, Chrome wuxuu soo sheegayaa ERR_TUNNEL_CONNECTION_FAILED. Sidaa darteed marka aad aragto bog buuxa oo "502 Bad Gateway" ah oo lagu soo bandhigay cinwaan https:// ah, waxay ku dhowdahay hubaal inay ka timid server-ka website-ka, ee aysan ka iman proxy-ga.

Xaqiiji adigoo daminaya proxy-ga oo dib u furaya isla boggaas. Haddii ay weli tahay 502, website-ka ayaa dhibaato qaba, waxa kaliya ee aad samayn karto waa inaad sugto ama aad u sheegto milkiilaha website-ka.

Marka uu proxy-gu dhab ahaan soo dirayo 502

  • Meesha la beegsanayo kama jawaabayso proxy-ga. Website-ku wuu dansan yahay, culeys ayaa saaran, ama wuxuu diidayaa xiriirrada ka imanaya kala-duwanaanta IP-ga proxy-ga.
  • Domain si qaldan loo qoray ama aan la xallin karin. Proxy-gu ma heli karo cinwaanka website-ka, markaa ma jirto wax loo gudbiyo.
  • Port-ka la beegsanayo wuu xiran yahay. Codsigu wuxuu beegsanayaa port uusan website-ku adeeg ka bixin.
  • Cillad kumeel-gaar ah oo dhanka proxy-ga ah. Waa mid naadir ah; waxaad dareemaysaa marka website kasta uu soo celiyo 502 adoo adeegsanaya hal proxy balse uu ku shaqeynayo mid kale.

Waxa la samaynayo deegaan kasta

  • Chrome ama borofayllada antidetect: ka fur website weyn oo kale isla borofaylka. Haddii uu furmo, proxy-gu wuu fiican yahay oo website-kii asalka ahaa ayaa dhibaatadu tahay.
  • Taleefannada: dami proxy-ga Wi-Fi-ga oo bogga ku tijaabi xogta moobilka si aad u aragto in website-ku qof walba ka xiran yahay.
  • curl: ku dar -v si aad u aragto 502 oo soo gaaraya isla markiiba ka dib CONNECT, ka dibna ku celi domain kale si aad u xaqiijiso.
  • Python requests: bogagga HTTP hubi response.status_code == 502 oo dib u tijaabi hakad ka dib; bogagga HTTPS tunnel-ka fashilmay waxaa loo soo saaraa sidii requests.exceptions.ProxyError. Kala fogee isku-dayada intii aad culeys xad-dhaaf ah ku wadi lahayd website-ka.

Tallaabo-tallaabo

  1. 1

    U fiirso halka uu 502 ka soo muuqanayo

    Bog 502 ah oo ku yaal cinwaan https wuxuu tilmaamayaa website-ka. Khalad tunnel oo gudaha Chrome wuxuu tilmaamayaa dhanka proxy-ga.

  2. 2

    Dami proxy-ga oo dib u cusboonaysii

    502 soo baxda proxy la'aan waxay ka dhigan tahay in website-ka laftiisu shaqaynayn.

  3. 3

    Ku fur website kale isla proxy-gaas

    Haddii website-yada kale shaqeeyaan, proxy-gu wuu fiican yahay waxaana diidaya ama dansan website-kii asalka ahaa oo kaliya.

  4. 4

    Ku hubi proxy-ga qalabka hubinta

    Ku dhaji sadarka qalabka hubinta proxy-ga. Haddii website kasta uu bixiyo HTTP 502, fur tikidh adoo raacinaya natiijada.

Su'aalaha inta badan la isweydiiyo

502 ma waxay ka dhigan tahay in proxy-gaygu dhacay?

Sida caadiga ah maya. Proxy dhacay ama joogsaday wuxuu inta badan keenaa xiriir fashilmay ama waqti-dhaaf; eeg proxy timeout.

Maxaa keenay in hal website oo kaliya uu soo celiyo 502 marka proxy-ga la isticmaalo?

Website-kaas ayaa laga yaabaa inuu cilladaysan yahay ama uusan ka jawaabayn xiriirrada ka imanaya IP-ga proxy-ga. Isku day mar dambe, ama isticmaal IP ku yaal waddan kale.

Waa maxay farqiga u dhexeeya 502 iyo 504?

502 waxay ka dhigan tahay jawaab aan sax ahayn ama inaan midna la helin; 504 waxay ka dhigan tahay in server-ka dhexe uu wax badan sugayay. Qalabka hubintu labadaba wuxuu u muujiyaa sidii HTTP <code>.

Scraper-kaygu mararka qaarkood wuxuu helaa 502. Ma tahay inaan beddelo proxy-yada?

502 marmar soo baxda waxay inta badan ka dhigan tahay bartilmaameed culeys saaran yahay. Dhim xawaaraha codsiyadaada oo kala fogee isku-dayada intaadan beddelin proxy-yada; eeg proxy-yada loogu talagalay web scraping.
