Kude kakhulu; Uzofunda

Isihloko somenzeli womsebenzisi sifana ne-ID yedijithali etshela amaseva mayelana nesofthiwe eyenza isicelo se-HTTP. Ekuklwebeni kwewebhu, ukusetha nokuzungezisa ama-ejenti wabasebenzisi kubalulekile ukuze ugweme ukutholwa nokudlula amasistimu e-anti-bot. Ngokulingisa abasebenzisi bangempela kusuka kuziphequluli namadivayisi, ungenza izicelo zakho zokukhuhla zibonakale ziyiqiniso.

Wake wazibuza ukuthi isoftware izethula kanjani kumaseva? Faka unhlokweni User-Agent —i-ID yedijithali eveza imininingwane ebalulekile mayelana neklayenti elenza isicelo se-HTTP. Njengoba usuzofunda, ukusetha i-ejenti yomsebenzisi kufanele ikhulwe!


Kulesi sihloko, sizodalula ukuthi i-ejenti yomsebenzisi iyini, kungani ibalulekile ekukhunjweni kwewebhu, nokuthi ukuyizungezisa kungakusiza kanjani ukuthi ugweme ukutholwa. Ulungele ukungena ngaphakathi? Asambe!

Yini Umenzeli Womsebenzisi?

User-Agent sihloko se-HTTP esidumile esisethwa ngokuzenzakalelayo izinhlelo zokusebenza namalabhulali lapho kwenziwa izicelo ze-HTTP. Iqukethe iyunithi yezinhlamvu echitha ubhontshisi mayelana nohlelo lwakho lokusebenza, isistimu yokusebenza, umdayisi, kanye nenguqulo yesofthiwe eyenza isicelo.


Leyo yunithi yezinhlamvu yaziwa nangokuthi i-ejenti yomsebenzisi noma i-UA . Kodwa kungani igama elithi “Umenzeli Womsebenzisi”? Kulula! Ngolimi lwe-IT, i -ejenti yomsebenzisi inoma yiluphi uhlelo, ilabhulali, noma ithuluzi elenza izicelo zewebhu egameni lakho.

Ukubhekisisa Intambo Yomenzeli Womsebenzisi

Nakhu ukuthi uchungechunge lwe-UA olusethwe yi-Chrome lubukeka kanjani kulezi zinsuku:

 Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/127.0.0.0 Safari/537.36

Uma udidwa yilolo chungechunge, awuwedwa. Kungani umenzeli womsebenzisi we-Chrome angaqukatha amagama afana nokuthi “Mozilla” kanye “neSafari”? 🤯


Nokho, kunomlando omncane ngemuva kwalokho, kodwa ngokweqiniso, kulula ukuvele uthembele kuphrojekthi yomthombo ovulekile njenge-UserAgentString.com . Vele unamathisele i-ejenti yomsebenzisi lapho, futhi uzothola zonke izincazelo oke wazibuza ngazo:


Ihlaziya i-ejenti yomsebenzisi kokuthi UserAgentString.com


Konke kunengqondo manje, akunjalo? ✅

Indima Yesihloko Somenzeli Womsebenzisi

Cabanga nge-ejenti yomsebenzisi njengephasiphothi wena (iklayenti) oyethula esikhumulweni sezindiza (iseva). Njengoba nje ipasipoti yakho itshela isikhulu ukuthi uvelaphi futhi ibasize banqume ukuthi bayakuvumela yini ukungena kwakho, umenzeli womsebenzisi utshela isayithi, “Hey, I'm Chrome on Windows, version XYZ” Lesi singeniso esincane sisiza iseva inqume ukuthi kanjani. futhi uma ukusingatha isicelo.


Lokho kuba lula nge-ejenti yomsebenzisi evumelekile


Nakuba iphasiphothi iphethe ulwazi lomuntu siqu njengegama lakho, usuku lokuzalwa, nendawo yokuzalwa, i-ejenti yomsebenzisi inikeza imininingwane mayelana nendawo oyicelayo. Kuhle, kodwa hlobo luni lolwazi? 🤔


Yebo, konke kuncike ekutheni isicelo sisuka kuphi:

  • Iziphequluli: Iheda User-Agent lapha ifana nedosi eningiliziwe, epakishwa egameni lesiphequluli, isistimu yokusebenza, izakhiwo, futhi ngezinye izikhathi ngisho nokucacisiwe mayelana nedivayisi.


  • Amalabhulali eklayenti le-HTTP noma izinhlelo zokusebenza zedeskithophu: User-Agent unikeza nje izisekelo, igama lomtapo wolwazi, kanye nenguqulo ngezikhathi ezithile.

Kungani Ukusetha I-ejenti Yomsebenzisi Kuyisihluthulelo ku-Web Scraping

Amasayithi amaningi anezinhlelo zokulwa ne-bot kanye ne-anti-scraping endaweni ukuze avikele amakhasi abo ewebhu kanye nedatha. 🛡️


Lobu buchwepheshe bokuvikela bubeka iso elibukhali ezicelweni ze-HTTP ezingenayo, buhogela ukungqubuzana namaphethini afana ne-bot. Uma bebamba eyodwa, abanqikazi ukuvimba isicelo futhi bangase bagweme ngisho nekheli lasesizindeni se-inthanethi lesigebengu ngezinhloso zabo ezinonya.


Kwenzekani lapho izixazululo ze-anti-bot zikumisa


User-Agent ungomunye wezihloko ze-HTTP lezi zinhlelo zokulwa ne-bot ezicubungula eduze. Phela, iyunithi yezinhlamvu kuleso sihloko isiza iseva ukuthi iqonde ukuthi isicelo sivela kusiphequluli sangempela esinochungechunge lwe-ejenti yomsebenzisi owaziwayo. Akumangalisi ukuthi User-Agent ingenye yezihloko ezibaluleke kakhulu ze-HTTP zokukhuhla iwebhu . 🕵️‍♂️


Indlela yokusebenza yokugwema amabhlogo? Zitholele ukukhwabanisa kwe-ejenti yomsebenzisi !


Ngokusetha iyunithi yezinhlamvu ye-UA mbumbulu, ungenza izicelo zakho zokuklwebha ezizenzakalelayo zibonakale zivela kumsebenzisi ongumuntu esipheqululini esijwayelekile. Le nqubo ifana nokwethula i-ID mbumbulu ukuze uthole ukuvikeleka okudlule.


Ungakhohlwa ukuthi User-Agent akalutho ngaphandle kwesihloko se-HTTP. Ngakho-ke, ungakunika noma yiliphi inani olifunayo. Ukushintsha i-ejenti yomsebenzisi ye-web scraping indala lelo qhinga likusiza ukuthi ugweme ukutholwa futhi uhlangane njengesiphequluli esijwayelekile. 🥷


Uyazibuza ukuthi ungasetha kanjani i-ejenti yomsebenzisi kumaklayenti adumile we-HTTP kanye nemitapo yolwazi yesiphequluli ezenzakalelayo? Landela imihlahlandlela yethu:

Umenzeli Ongcono Kakhulu Wokusebenzisa I-inthanethi

Ubani inkosi yabasebenzeli abasebenzisi uma kuziwa ekukhunjweni kwewebhu? 👑


Hhayi-ke, akuwona ubukhosi impela kepha ngaphezulu kwe-oligarchy. Akekho noyedwa umenzeli womsebenzisi oyedwa oma ikhanda namahlombe ngaphezu kwabanye. Empeleni, noma iyiphi iyunithi yezinhlamvu ye-UA evela kuziphequluli zesimanje namadivayisi kuhle ukuhamba. Ngakho-ke, ayikho i-ejenti yomsebenzisi "engcono kakhulu" yokukhuhla.

I-User-Agent Knights of the Round Table


Abasebenzisi abavela ezinguqulweni zakamuva ze-Chrome, Firefox, Safari, Opera, Edge, nezinye iziphequluli ezidumile ezinhlelweni ze-macOS neWindows zonke ziyizinketho eziqinile. Okufanayo kuya nge-UA yezinguqulo zakamuva ze-Chrome ne-Safari yeselula kumadivayisi we-Android ne-iOS.


Nalu uhlu olukhethwe ngesandla lwama-ejenti wabasebenzisi oluzokhuhlwa:

Gwema Ukuvinjelwa Ngokuzungezisa Umenzeli Womsebenzisi

Ngakho-ke, ucabanga ukuthi ukushintsha nje User-Agent Ozenzakalelayo womtapo wezincwadi weklayenti lakho le-HTTP nomunye ovela esipheqululini kungenza iqhinga lokuvika ama-anti-bot systems? Hhayi-ke, akunjalo...


Uma ugcwalisa iseva ngezicelo User-Agent ofanayo futhi kusukela ku-IP efanayo, empeleni uphakamisa ifulegi elithi, “Ngibheke, ngiyi-bot!” 🤖


Ukuze uthuthukise igeyimu yakho futhi wenze kube nzima ukuthi lezo zivikelo ze-anti-bot zibambelele, udinga ukuhlanganisa izinto. Yilapho ukuzungezisa kwe User-Agent omile, osemhlabeni wangempela, shintsha ngesicelo ngasinye.


Ngisho noDrake weseka ukuzungezisa i-ejenti yomsebenzisi


Le nqubo isiza izicelo zakho ukuthi zihlangane kangcono nethrafikhi evamile futhi igweme ukumakwa njengokuzenzakalelayo.


Nansi imiyalelo yezinga eliphezulu yokuthi ungazungezisa kanjani ama-ejenti wabasebenzisi:

  1. Qoqa uhlu lwama-ejenti abasebenzisi : Qoqa isethi yezintambo ze-UA kusuka kuziphequluli namadivayisi ahlukahlukene.

  2. Khipha i-ejenti yomsebenzisi engahleliwe : Bhala ingqondo elula ukuze ukhethe ngokungahleliwe iyunithi yezinhlamvu ye-ejenti yomsebenzisi ohlwini.

  3. Lungiselela iklayenti lakho : Setha iyunithi yezinhlamvu ze-ejenti yomsebenzisi ekhethwe ngokungahleliwe kusihloko User-Agent weklayenti lakho le-HTTP.


Manje, ukhathazekile ngokugcina uhlu lwakho lwabenzeli abasebenzisi lusha, ungaqiniseki ukuthi ulisebenzisa kanjani ukushintshanisa, noma ukhathazekile ngokuthi izixazululo ezithuthukisiwe ze-anti-bot zisengakuvimbela? 😩


Lezo izinkathazo ezivumelekile, ikakhulukazi njengoba ukuzungezisa i-ejenti yomsebenzisi kumane kunwaya indawo yokugwema ukutholwa kwe-bot.
