- Umehluko omkhulu phakathi kwama-proxies omphakathi, isikhungo sedatha, kanye nama-proxies eselula ngokusekelwe edumeleni le-IP kanye nezinga lempumelelo.
- Ukubaluleka kokujikeleza ikheli le-IP okuzenzakalelayo kanye nokuphathwa kweseshini enamathelayo ukuze kugwenywe izinhlelo zokulwa ne-bot.
- Ukuhlaziywa kwamamodeli wamanani asekelwe ku-bandwidth (GB) uma kuqhathaniswa namamodeli esicelo aphumelelayo ekukhuculeni ama-API.
Ukuskena iwebhu enkulu ngaphandle kwesu le-IP empeleni kuyindlela elula. Uma uzama ukukhipha izinkulungwane zamakhasi kusuka kuxhumo olulodwa, iseva yewebhusayithi izokubamba ngokushesha, ikushiye ubambeke ngephutha elingu-403 noma i-CAPTCHA engenakwenzeka ukuyixazulula. Ukuze ugweme lokhu kukhanda, ama-proxies ayasebenza. Asebenza njengabalamuli, afihle umkhondo wakho futhi asabalalise umthwalo emakhelini amaningi.
Kuhlelo lwanamuhla, lapho ubuhlakani bokwenziwa budinga khona idatha eningi, abanikazi bamawebhusayithi bathuthukise umdlalo wabo ngezinyathelo zokuphepha ezinamandla kakhulu. Ngakho-ke, akukhona nje ukushintsha ikheli lakho le-IP, kodwa nokukhetha elifanele. uhlobo olufanele lommeleli futhi ulungiselele ukujikeleza okuhlakaniphile okulingisa ukuziphatha komsebenzisi wangempela, ngaleyo ndlela kuvimbele izinhlelo zokuthola ukuthi zingasibeki uphawu njenge-bots.
Iyini ngempela i-proxy futhi isisindisa kanjani isikhumba sethu?
Ngamagama alula, iseva yephroksi isebenza njengebhuloho phakathi kweskripthi sakho sokuskena kanye newebhusayithi eqondiwe. Esikhundleni sokuthi ikhompyutha yakho ixhumeke ngqo, isicelo siqala sidlule kuphroksi, esidlulisela kuseva. Lokhu kwenza iwebhusayithi icabange ukuthi isicelo sivela ekhelini le-IP lephroksi hhayi elakho, okukuvumela ukuthi... gcina ukungaziwa futhi uvimbele ikheli lakho lendawo ukuthi ligcine lifakwe ohlwini olumnyama.
Lokhu kubalulekile hhayi nje ngenxa yokuvinjelwa, kodwa futhi ngenxa ye ukukhomba kwe-geoAmawebhusayithi amaningi ashintsha amanani awo, amazinga esitoko, noma imiphumela yokusesha kuye ngokuthi uwafinyelela kuphi. Uma udinga idatha enembile evela eJapan noma e-United States, udinga ama-proxies atholakala kulezo zifunda ukuze iseva ikwazi ukuletha okuqukethwe okuqondene naleyo makethe.
Izinhlobo zama-proxies: Yikuphi okufanele ukhethe kuye ngomgomo wakho?
Akuwona wonke ama-proxies adalwe ngokulinganayo, futhi ukukhetha okungalungile kungaba ukuchitha imali. Kuye ngokuthi isayithi olikhahlelayo lilukhuni kangakanani, kuzodingeka ukhethe phakathi kwalezi zinketho ezintathu eziyinhloko:
- Amaphroksi Esikhungo Sedatha: Son los más veloces y económicos. Provienen de servidores en la nube, por lo que tienen un ancho de banda brutal. El problema es que son fáciles de detectar porque sus rangos de IP están etiquetados como «servidores». Son ideales para amawebhusayithi avumelayo noma imisebenzi yokukhipha ngokushesha.
- Ama-Proxies Ezindawo Zokuhlala: Lawa ma-IP angawamadivayisi wangempela angawabasebenzisi basekhaya. Kuwebhusayithi, cishe akunakwenzeka ukuwahlukanisa nesivakashi esingumuntu, okunciphisa kakhulu amathuba okuvinjelwa. Ayindlela engcono kakhulu yalokhu amapulatifomu aqinile njenge-Amazon noma amanethiwekhi omphakathi, yize zivame ukubiza kakhulu futhi zikhokhiswa nge-GB ngayinye.
- Ama-Proxies Eselula: Utilizan IPs de redes 4G/5G. Son el «santo grial» del scraping porque las webs no pueden bloquear rangos móviles enteros sin riesgo de dejar fuera a miles de usuarios reales. Son perfectos para Okuqukethwe kweselula okukhethekileyize izindleko zayo ziphakeme kakhulu.
Amasu athuthukile okugwema ukutholakala
Ukuba nama-IP ayinkulungwane akusizi ngalutho uma uwasebenzisa kabi. Isihluthulelo siku- Ukuzungeziswa kwekheli le-IPEsikhundleni sokusebenzisa uxhumano olulodwa kuze kube yilapho lufa, uhlelo lushintsha ikheli le-IP ngesicelo ngasinye. Ngale ndlela, iseva ibona izicelo ezivela kubasebenzisi abaningi abahlukene esikhundleni se-bot eyodwa nje eyenza umsindo.
Kodwa-ke, kunezimo lapho ukuzungeza ikheli le-IP esinyathelweni ngasinye kungaphula ukugeleza, njengalapho udinga ukungena noma ukwengeza imikhiqizo enqoleni. Yilapho ukuzungeza ikheli le-IP kungena khona. izikhathi ezinamathelayo (amaseshini ahleliwe), akuvumela ukuthi ugcine i-IP efanayo isikhathi esithile (kusukela kumaminithi ambalwa kuya emahoreni angama-24) ukuze ulondoloze isimo seseshini ngaphambi kokushintshela kwenye i-IP.
Ukuqhathaniswa kwezixazululo namamodeli ezindleko
Uma unesabelomali esincane, into ehlakaniphile ongayenza ukubheka abahlinzeki abanomodeli khokha njengoba uhamba (khokha njengoba uhamba) kanye nethrafikhi engaphelelwa yisikhathi. Izinketho ezifana ne-DataImpulse zihlukile ngokunikeza isevisi yokuhlala ngo-$1/GB, okushibhile kakhulu uma ukhipha i-HTML elula kuphela. Kulabo abafuna ukulula, kukhona Ama-API e-SERP (como Decodo o ScraperAPI), que no te dan la IP «en bruto», sino que te devuelven el dato ya parseado en JSON, encargándose ellas mismas de los CAPTCHAs y la rotación.
Kumaphrojekthi ezinkampani, izinkampani ezinkulu ezifana neBright Data noma i-Oxylabs zinikeza ingqalasizinda enkulu nge ukuhlukaniswa kwe-granular ngedolobha noma i-ASN, okuqinisekisa izinga lempumelelo eliphezulu kakhulu, yize intengo iphakeme kakhulu. Ngakolunye uhlangothi, amathuluzi angenakho ikhodi afana neThunderbit ahlanganisa ukujikeleza kwe-IP kanye ne-AI kusandiso esisodwa, okwenza impilo ibe lula kulabo abangafuni ukuhlushwa yizikripthi ze-Python.
Ukucushwa kobuchwepheshe kanye nemikhuba emihle kakhulu
Ukuze usebenzise lokhu ngekhodi (isibonelo, nge-Python kanye ne-Requests), vele udlulise isichazamazwi se-proxy esicelweni. Kodwa-ke, ukuze uhlelo lube luqinile, kunconywa ukusebenzisa i- ukulawulwa kwesilinganiso sohlelo lokusebenza (ukugoqa), okunezela ukubambezeleka okungahleliwe phakathi kwezicelo ukuze kugwenywe ukulayisha ngokweqile iseva futhi kubonakale sengathi kungabantu.
Elinye icebo eliyinhloko yileli Ukujikeleziswa kwe-User-AgentUkushintsha ikheli lakho le-IP akusizi ngalutho uma zonke izicelo zakho zibonisa ukuthi zivela enguqulweni efanayo ye-Chrome ku-Windows. Ukushintsha izihloko zesiphequluli kanye nokujikeleza kwe-IP kwenza izicelo zakho zihluke kakhulu kuthrafikhi yemvelo.
Ukucatshangelwa kwezomthetho nokuziphatha
Nakuba ukusebenzisa ama-proxies kusemthethweni, ukuziklwebha kufanele kwenziwe ngokucophelela. Umthetho wegolide uthi hlonipha ifayela le-robots.txt futhi ugweme ukulayisha ngokweqile amaseva oqondiwe kuze kube sezingeni lokuwasusa ku-inthanethi. Indlela ephephile kakhulu ukukhipha idatha etholakala emphakathini njalo nokugwema ukugcinwa kwedatha yomuntu siqu ngokungakhethi ngaphansi kwemithetho efana ne-GDPR.
Ukukhishwa kwedatha okuphumelelayo kuncike ekulinganiseni ivolumu yesicelo, ikhwalithi ye-IP, kanye nekhono lokulingisa ukuziphatha kokuphequlula kwabantu. Kungakhathaliseki ukuthi ukhetha amandla ama-proxies ajikelezayo, isivinini sama-proxies esikhungo sedatha, noma ukulula kwe-API ephethwe, isihluthulelo sisekuhlukaniseni ubunikazi bokuxhumana kwethu ukuze ukugeleza kwedatha kungami lapho kuqala inkinga.
