Amasethi amabili e-proxy angakha iketanga ongakuhlelelanga

Uhlelo lwakho lokusebenza lukhomba ku-proxy B, kodwa lwethulwe nge-wrapper elungiselelwe i-proxy A. Iwebhusayithi ibona ikuphi ukuphuma? Impendulo incike ekutheni i-wrapper ibamba ukuxhumana kuphi.

Ekuhlelweni okulula okufakwe ngaphakathi, uhlelo lokusebenza luqala ngokuzama ukuxhuma ku-B. I-wrapper ibamba lokho kuxhumana bese ikudlulisa ku-A. Khona-ke uhlelo lokusebenza lukhuluma iphrothokholi ye-proxy ka-B phezu komfula ovelayo, futhi u-B wenza ukuxhumana kokugcina newebhusayithi.

application → wrapper proxy A → application proxy B → website

Iwebhusayithi ibona ukuxhumana kokugcina okuphumayo kuka-B. U-B ubona ukuxhumana okufika ngo-A. Lokhu kuhlukile ekutheni i-wrapper ibhale ngokuthula phezu kwesethi ye-proxy yohlelo lokusebenza uqobo.

Umdwebo olula unemibandela

Imithetho yokwedlula, izingcingo ze-socket ezingasekelwe, izinqubo ezikhona kanye nemodeli yokubamba yomkhiqizo ngamunye kungashintsha indlela. Amanye ama-wrapper angakhipha i-proxy yawo noma izindawo ezikhethiwe. Ungacabangi ukuthi zonke izithombi zamathuluzi zihlangana ngendlela efanayo.

Incazelo ye-proxychains-ng ichaza indlela yayo yokubamba kanye nemikhawulo. Uhlelo olusebenzisa ukusekelwa kwe-proxy kwemvelo lusenza ukuxhumana kwenethiwekhi kuleyo proxy, okungomunye wabangeneleli bokubamba.

Ngeketanga lamabomu asemphakathini angagunyaziwe, uhlu lwama-proxy amahhala lunikeza abangeneleli okumele amaphrothokholi abo ahambisane nethuluzi ngalinye. Ukuphuma okungalindelekile, rekhoda amakheli amathathu ngokwahlukana: iphuzu lokugcina elikhethwe uhlelo lokusebenza, iphuzu lokugcina elikhethwe i-wrapper, kanye nomphumela obonwa yiwebhusayithi. Ukubuka kuphela izilungiselelo zesiphequluli kuphuthelwa ungqimba oluphakathi.

Sebenzisa indlela eyodwa ngenkathi usungula ukuziphatha okuhloswe, bese wengeza enye kuphela uma iketanga lidingeka. Ukugxuma okwengeziwe kungangeza izindawo zokwehluleka kanye nobudlelwano bokuthemba obuhlukile. Akususi ngokuzenzakalela amakhukhi okukhomba futhi akwenzi ukuxhumana konke kuhlelo lokusebenza kulandele indlela efanayo.
