Heamana vs Heamana-kaiwhakahaere i te Tīwhiri Modern: Me Pehea te Whiriwhiri

Ka taea e te scraper te ahua he pumau i te whakawhanaketanga, ā, ka taea tonu te hinga i te whakaputanga i te wa e pā ana ki ngā whāinga pono, te nui o te whakauru, te tango whakaahua o te pātea, me te huarahi proxy. Ko te whakatau tuatahi e pā ana ki ngā tīma ko te whakahaere i ngā heamana, i ngā heamana-kaiwhakahaere rānei. Ka pā te whiriwhiringa ki te reiti angitu, te reiti aukati, te pāmahana, te utu hanganga, me te CPSR.

Ehara i te mea he whakaritenga māmā te whiriwhiri i waenga i ngā heamana me ngā heamana-kaiwhakahaere. Ka whakahaerehia ngā heamana me te kore e kitea te atanga kaiwhakamahi, ā, he tere, he māmā, he ngawari hoki ki te whakawhanake. Ka whakahaerehia ngā heamana-kaiwhakahaere me te atanga e kitea ana, ā, ka taea e rātou te whakatutuki i te taiao kaiwhakamahi pono, e taea ana te awhina i ngā whāinga e pā ana ki te tango whakaahua. Ko te whakaritenga pai ka whakamahi i te rua: heamana mō te nui, he heamana-kaiwhakahaere mō ngā rerenga pātea.

Mō ngā tīma e hanga ana i ngā tīwhiri, i ngā mahi aunoa, me whakaarohia te āhua o te tirohanga hei whakatau huarahi. Whakamahia te āhua iti rawa e taea te whakahoki i ngā raraunga pono, ā, ka piki anake i te wā e tika ana te tiaki o te whāinga ki te utu tāpiri.

He aha ngā Heamana me ngā Heamana-kaiwhakahaere

He heamana he miihini tirotiro pono e whakahaerehia ana me te kore e kitea te matapihi. Ka taea e ia te uta i ngā whārangi, te whakahaere i te JavaScript, te whakaatu i ngā ihirangi DOM, te pāwhiri i ngā pātene, te tuku i ngā puka, me te tango raraunga me te kore e whakaatu i te UI tirotiro.

Ka whakahaerehia te heamana-kaiwhakahaere me te atanga e kitea ana, e tata ana ki te āhua o te kaiwhakamahi noa e whakatuwhera ana i te Chrome, Firefox, rānei, i tētahi atu tirotiro i runga i te taputapu.

E rua ngā āhua e wātea ana i ngā taputapu aunoa rongonui pērā i Playwright, Puppeteer, me Selenium. Ko te rerekētanga kāore e pā ana ki te mea he “pono” te tirotiro. Ko te rerekētanga he pēhea te whakaatu o te tirotiro i te whakaatu, te matapihi, te rorohiko, te wā, me ngā tohu taumata pūnaha.

Ko te heamana Chromium hou he tino tata ki te heamana-kaiwhakahaere Chromium i ngā putanga heamana tawhito. Ka awhina tēnei ki te whakaiti i ngā kōpaki mōhiohio, engari kāore e tango i te hiahia mō te hoahoa wātea tika, te whakaritenga whakaahua, me te rautaki proxy.

Whakatau Tere: Kahea ki te Whakamahi i ngā Heamana vs Heamana-kaiwhakahaere

Whakamahia ngā heamana i te wā e nui ana te tere, te rahi, me te utu hanganga iti i te mea he nui ake te pono o te tirotiro. Whakamahia ngā heamana-kaiwhakahaere i te wā e pā ana ki te mahi ki te rehita, te tango whakaahua, rānei, e hinga ana i te heamana i te wā e noho ana ngā proxy i te pai me te pātea tika.

He ture whaihua he māmā:

Tīmatahia te heamana, me te ine i te tika, ā, ka piki ki te heamana-kaiwhakahaere anake mō ngā whāinga, ngā mahi e tika ana.

Ka pupuri tēnei anga i ngā utu o te hanganga i raro i te mana, i te wā e noho ana te kōwhiringa ki te whakamahi i ngā pūtirotiro headful i te wā e whakapai ana i te angitū.

He aha te Pānga o te Mōhiti Pūtirotiro ki te Whakaora

Ka kore e aromatawai anake ngā paetukutuku i ngā wāhitau IP. Ka taea hoki e rātou te aromatawai i ngā whanonga pūtirotiro, ngā tohu rorohiko, ngā āhuatanga e kitea ana i te JavaScript, te wā, ngā pihikete, te rokiroki, me te mau tonu o te whatunga.

Koia te take e taea ai e te pūnaha whakaora e whakamahi ana i ngā web scraping proxies te hinga i te wā e titiro ana te taiao pūtirotiro hei mea rerekē.

Ka taea te kitea te mōhiti headless i te wā e kore e tika ngā tautuhinga, e pātea ana, e rerekē ana ki te toenga o te wāhanga. Ka taea e te mōhiti headful te whakaiti i ētahi o ēnā rerekētanga, engari kāore e riro hei rongoā mō te katoa. Ka taea e te rongonui kino o te proxy, te rerekētanga geo, te pāmahana kaha, me ngā pihikete pakaru te pā ki ngā aukati.

Ko te mōhiti pūtirotiro he rārangi kotahi. Ko te rautaki proxy, te whakahaere wāhanga, te mau tonu o te fingerprint, me te whakatutukitanga o te ihirangi ka mahi tahi.

Te Whakatakoto Tūtohu: Tere, Pātea, me te Utu

He pai ake ngā pūtirotiro headless i te nuinga o te wā nāna i te karo i te utu o te UI e kitea ana. He māmā ki te whakahaere i roto i ngā ipu, he māmā ki te whakarite ki te rārangi, ā, he pai ake mō te kohikohi raraunga nui.

He taumaha ngā pūtirotiro headful. Ka pau rātou i te nuinga o te CPU me te mahara, he pātea te whakahaere i te rahi, ā, ka hiahia pea ki te hanganga e mātaihia ana. Engari mō ētahi whāinga, ka taea e te pātea e whakapai i te ora o te wāhanga.

Me ine te whakatakoto tūtohu i roto i:

• Te reiti angitū
• Te reiti aukati
• Te reiti CAPTCHA
• Te depth whakahoki
• Te P95 te wā
• Te whakamahi rauemi
• Te ora wāhanga
• CPSR

Ko te CPSR e pā ana ki te utu mō ia tono angitū.

I ngā kupu māmā: Ka kī te CPSR ki a koe te utu o ia hua tika i muri i te whakapau i te proxy, te rorohiko, ngā whakahoki, me ngā wāhanga i hinga.

He mea nui te pūtirotiro headful ki te utu tāpiri anake i te wā e whakapai ana i te putanga tika i te nui e taea te whakakī i te utu hanganga tāpiri.

Me pēhea te Whakauru i ngā Proxy ki te Whakatau

Me whiriwhiri te mōhiti pūtirotiro me te momo proxy i te wā kotahi.

Mō ngā whārangi tūmatanui me te iti o te pānga, ka taea e ngā datacenter proxies te mahi pai me ngā pūtirotiro headless. Ko tēnei whakaritenga he tere, he taea te whakahoki, ā, he utu pai.

Mō ngā rerenga e tiakina ana, e pā ana ki te geo, e teitei ana i te wāhanga, ka taea e ngā residential proxies te pai ake. Ka taea e ngā huarahi residential te whakapai i te pātea o te whatunga, i te wā e whakapai ana ngā pūtirotiro headful, e te whakarite ana i ngā wāhanga ki te taha kiritaki.

He tauira whakaputa noa e pērā ana:

Ka āhei tēnei ki te aukati i ngā rōpū ki te whakamahi i te whakaritenga tino utu i ngā wā katoa.

Te Tirohanga Headless: He aha te mea ka Tūtohu

Ka rarahi te tirohanga headless i te nuinga o te wā kāore e pā ki te tohu kotahi. Ka whakakotahi te nuinga o ngā pūnaha hou i ngā tohu maha.

Ko ngā raru e pā ana:

• navigator.webdriver te whakaatu
• te rahi viewport kāore e tika
• ngā pūrongo kāore e kitea
• te kaiwhakahaere WebGL rerekē, te kaiwhakahaere
• ngā tohu User-Agent me te OS kāore e rite
• ngā plugins kāore e kitea, ngā taputapu pā media
• te wā tino pai rawa
• ngā whanonga TLS, HTTP rerekē
• kāore he hitori pihikete
• te rerekētanga WebRTC
• te tere tono teitei

Ko etahi o enei e pa ana ki te ahua o te tirohanga. Ko etahi e pa ana ki te hoahoa profaili kino, te hē o te proxy, te whanonga aunoa.

Mo te whakarapopototanga hohonu o nga tohu taha-kai, tirohia te tango i nga tohu tirohanga mo te tango paetukutuku. E whakamārama ana i nga tohu ka taea e nga proxy te whakatika me nga mea e tika ana ki te whakahaere i te papa tirohanga.

Kahea e tika ana nga Tirohanga Headless

Ko nga tirohanga headless te tikanga ko te tīmatanga pai mo nga tīma tango.

Whakamahia te headless ina:

• he whārangi tūmatanui
• kāore e hiahiatia te rehita
• e hiahiatia ana te whakakite i te JavaScript engari kāore e tino tiakina
• he mea nui te nui o te whakawhiti
• me noho te utu o te hangarau i raro
• he poto nga huihuinga tirohanga
• he māmā te whakatau raraunga

He tino whaihua te headless mo te tirohanga eCommerce, te tirohanga SEO, te whakau i nga URL, te whakakite i nga whārangi tūmatanui, me nga taraiwa rahi.

Mena ka hoki mai te whāinga i nga ihirangi tika me nga hē iti me te pāmahana e whakaaetia ana, me noho te headless hei paerewa.

Kahea e tika ana nga Tirohanga Headful

He mea nui te whakamātautau i nga tirohanga headful ina ka pā te mahi ki te haerenga kaiwhakamahi pono.

Whakamahia te headful ina:

• e hiahiatia ana te rehita, te SSO
• e tirohia ana e te paetukutuku nga whakaahua, nga pāpāho
• ka whakahau te headless i nga CAPTCHA i nga huihuinga
• ka hinga nga whārangi i muri i te pānga, kāore i te uta tuatahi
• he mea nui nga huihuinga roa
• he teitei te pānga anti-bot
• e pā ana nga mahi i runga i te pūkete

Ka taea e te headful te awhina na te mea ka taea e ia te whakaatu i te taiao tirohanga e tino pai ana. Heoi, me whakamātautau i runga i te rōpū whakahaere i mua i te whakarewatanga.

Kaua e neke katoa ki te headful i te mea kotahi te whāinga e hinga ana.

He Ara Whakatūpato Whaihua

Whakamahia tēnei ara i mua i te hanga i ngā panoni utu nui ki te hangarau.

1. Tīmatahia ki te mōhiohio headless hou.
2. Whakamātauria te ihirangi whārangi, kāore e tika ana te tūtohi HTTP.
3. Whakatika i te tirohanga, te wā, te reo, me te rokiroki huihuinga.
4. Whakauru te wāhi proxy ki te profaili tirohanga.
5. Whakaritea te maha me te pēhanga whakahou.
6. Whakamātautau i nga huihuinga piri.
7. Tirohia te headless ki te headful i runga i te whāinga kotahi.
8. Nekehia ngā wāhanga e hinga ana ki te headful.

Ka tiakina tēnei huarahi te CPSR i te wā e whakapai ana i te pono i ngā wāhi e tika ana.

Nga Tuhinga Whakamahi mo Playwright, Puppeteer, me Selenium

Playwright

Ko te Playwright he whiriwhiri kaha mo te tango hou na te mea e tautoko ana i te Chromium, Firefox, me WebKit. Ka taea hoki e ia te whakarite i nga horopaki tirohanga.

Whakamahia nga horopaki motuhake mo nga pūkete rerekē, nga GEO, ranei nga momo huihuinga. Tiakina te huarahi proxy, te wā, te reo, me te rokiroki i roto i ia horopaki.

Puppeteer

Ko te Puppeteer he pai mo te tango me te aunoa i runga i te Chromium. He maamaa, he nui te whakamahi, he pai mo nga mahi tuatahi i runga i te headless.

I te whakamahi i te Puppeteer, me noho mōhio ki ngā flag tīmata, ngā paerewa tirohanga, me te whakaritenga proxy. Ka taea e ngā hē iti te puta i te rahi.

Selenium

Ko te Selenium e whakamahia ana i te nuinga o te wā ina hiahia nga tīma ki te tautoko tirohanga whānui, ngā rerenga tawhito, rānei te aunoa e pā ana ki te pānga.

Mo nga mahi e hiahiatia ana te rehita, ka taea te whakamahi i te Selenium me te tirohanga headful, engari me aroturukihia te whakamahi rauemi me te pumau o nga huihuinga.

Te Rarangi Rauemi: He Awhina engari He Tūpono

Ko te aukati i nga whakaahua, nga pūtau, nga tuhinga tātaritanga, rānei nga kaiwhakaatu tuatoru ka taea te whakaheke i te utu me te tere o te tango.

Engari, ka taea e te aukati rauemi kaha te whakakore i te rautaki whārangi, i ngā whakaritenga tirohanga.

Mo nga mahi headless, he whaihua te aukati rauemi ina:

• ka taea e te whārangi te whakakite i te tika
• ka noho tonu nga tuhinga e hiahiatia ana
• ka whakauhia te whakaritenga o te raraunga
• kāore e whakaoho i te whanonga anti-tamper

Mo nga mahi headful, me noho mōhio ake. Mena ko te whāinga ko te pono, ko te tango i te maha o ngā rauemi ka taea te whakaiti i te āhua o te huihuinga.

He aha te Me Tirohia i mua i te Whakatipu

Me whakawhirinaki te whakatau mō te ahua tirohanga ki ngā raraunga.

Tirohia ēnei tohu:

Arohia te mana o te whārangi anake. Ka taea e te whārangi te whakahoki 200, ā, ka noho tonu ngā raraunga kāore e kitea, he hē, he rerekē te rohe.

Te Whakaaturanga Pāpori: Te Mātai Utu eCommerce

He rōpū eCommerce e mātai ana i ngā whārangi hua e mano i ngā kaiwhakarato rerekē.

Ka tīmata rātou ki te whakamahi i te Chromium kāore he upoko me ngā proxy pokanga mō te kohinga whānui. Ko te nuinga o ngā kaiwhakarato e whakahoki ana i ngā raraunga hua māmā me te iti o te pānga.

E rua ngā kaiwhakarato e tīmata ana ki te whakahoki i ngā aukati māmā me ngā kōwae utu e ngaro ana. Kāore e taea te neke i te pūnaha katoa ki ngā pūtirotiro he upoko, ka hanga te rōpū i tētahi ara motuhake mō ēnā rohe e whakamahi ana i ngā proxy kāinga me ngā horopaki pūtirotiro mau.

Ko te hua he pūnaha hāngai. Ka whakahaerehia e te kāore he upoko te nuinga o te rahi, i te wā e whiwhi ana ngā whāinga uaua i tētahi whakaritenga pono me te utu nui anake i te wā e hiahiatia ana.

Te Whakaaturanga Pāpori: Te Pānui Haerenga Whakamahi

He rōpū raraunga haerenga e hiahia ana ki te kohikohi i te wātea mai i tētahi tauranga kaiwhakarato e hiahiatia ana te taki.

Ka pai te mōhiohio kāore he upoko mō te whārangi taki engari ka hinga i muri i ngā pānuitanga rārangi. Ka whakahokia ngā huihuinga, ā, ka piki te pānga huna.

Ka whakamātau te rōpū i te Chromium he upoko me ngā proxy kāinga mau, ngā pūnaha pūtirotiro pūmau, me te tere pānui iti. Ka piki te ora o ngā huihuinga, ā, ka heke te hiahiatia o te āwhina a te tangata.

Ka nui ake te utu mō ia huihuinga, engari ka piki te CPSR nāna i te mea kāore e hiahiatia ngā mahi e hinga ana.

Kia Mātakitaki i ēnei Mōhiohio Hinga

Te Whakarite i te Upoko hei Whakaoti Whānui

Ka taea tonu te hinga i te mōhiohio he upoko mēnā he hē ngā proxy, te rohe, ngā puku, rānei te wā.

Te Whakamahi i ngā Pūtirotiro He Upoko

Ka taea te piki te utu i te wā e whakamahia ana te pūtirotiro he upoko i te rahi. Whakamahia i reira e whakaatu ana ngā pānga.

Te Pāhi i ngā Tohu Pūtirotiro

Kaore te mōhiohio anake e whakaoti i ngā raru tohu. Ko te User-Agent, WebGL, ngā pūtau, te wā, te penapena, me te WebRTC e pā ana tonu.

Mō ngā raru e pā ana ki te WebRTC, tirohia tā mātou aratohu mō WebRTC leaks.

Te Aukati i te Rahi o ngā Rauemi

Mēnā ka huri ngā rauemi e aukati ana i te wheako o te whārangi, ka taea e tō scraper te kohikohi i ngā raraunga kāore e oti ana, kāore e taea te whakatū i ngā tirohanga pono.

Te Whakatipu i te Rahi i mua i te Whakamātautau Pātea

Ka taea e ngā whakamātautau iti te huna i ngā hinga i te whakaputa. Ka tīmata ki ngā whāinga, rahi, me ngā GEO e whakaatu ana.

Ngā Whakatakotoranga Utu me te Hangarau

Ka tautoko ngā pūtirotiro kāore he upoko i te nui o te pāhekoheko mō ia miihini. Ka māmā ake te whakatipu mō te pānui whānui me te mātai.

Ka hiahia ngā pūtirotiro he upoko ki te nui ake o te CPU, te mahara, me ngā whakaritenga e pā ana ki te whakaatu. I ngā taiao kapua, ka taea e rātou te hiahia ki ngā whakaaturanga ā-ipurangi, ki te whakaritenga ipu.

He rautaki utu pai ko:

• Whakamahia ngā kaihoko HTTP i te wā e taea ana.
• Whakamahia ngā pūtirotiro kāore he upoko mō te whakatakotoranga JavaScript.
• Whakamahia ngā pūtirotiro he upoko anake mō ngā mahi uaua.
• Whakamahia ngā proxy kāinga anake i reira e piki ana te pono o te whatunga.
• Penapena ngā ara pokanga mō ngā whārangi e pākiki ana, e nui ana te rahi.

Ka tiakina tēnei huarahi i te utu i te wā e piki ana te coverage.

Te Whakarite me te Kounga Raraunga

Kaore te mōhiohio pūtirotiro e huri i te hiahia mō te kohikohi raraunga e whai tikanga ana.

Me whai i nga ture e pa ana, nga tikanga o te papa, nga whakaritenga mo te noho muna, me nga kaupapa whakahaere o roto. Tiakina nga rīpoata o nga mahi kohikohi, pupuri i nga rohe tere, me te karo i te kohikohi raraunga i tua atu i te awhe kua whakaaetia.

Ko te pai o te whakaritenga me te kounga raraunga pai e tautoko ana i tetahi atu. He ngawari te tirotiro i tetahi scraper e whakahaerehia ana, e ngawari ana ki te whakahaere.

Nga Pātai e Pā Ana

He aha te rerekētanga i waenga i ngā pūtirotiro headless me headful?

Ka whakahaerehia te pūtirotiro headless me te kore UI e kitea. Ka whakahaerehia te pūtirotiro headful me te pūtirotiro e kitea ana. Ka taea e rua te whakamahi i nga miihini pūtirotiro pono, engari ka whakakitea e rātou ngā tohu rerekē i te whakatakotoranga me ngā tohu pūnaha.

Ka taea te kitea te mōhiti headless?

Ka taea. He pai ake ngā pūtirotiro headless hou i ngā putanga tawhito, engari ko te whakaritenga kino, ngā tohu aunoa, ngā whakaritenga kāore e taea, kāore e taea te whakakī i ngā āhuatanga pūtirotiro ka piki te whakapae.

He pai ake te headful mo te kohikohi raraunga?

Kāore. Ka taea e te headful te awhina i ngā whāinga e kaha ana, engari he pātea me te utu nui. Whakamahia anake i te wā e whakapai ana i te reiti angitu, te ora o ngā wā, rānei te CPSR.

Me tīmata au ki te headless, ki te headful?

Tīmata ki te headless mēnā kāore e mārama te mahi ki te whakauru, ki te pūkete, ki te pātea ki te fingerprint. Tīmata ki te headful anake i te wā e whakaatu ana te whakamātautau kāore e taea e te headless te whakaputa i ngā hua pūmau, tika.

He mea nui ake ngā proxy i te mōhiti pūtirotiro?

E rua e mea nui ana. Ka pā te momo proxy ki te rongonui IP, te wāhi, me te whanonga whatunga. Ka pā te mōhiti pūtirotiro ki ngā tohu taha-kai. Ka whakakotahi ngā pūnaha kohikohi kaha i ngā paparanga e rua.

Ka taea e Playwright te whakahaere i te headless me te headful?

Āe. Ka tautoko a Playwright i ngā mōhiti e rua, ā, he māmā te wehe i ngā horopaki pūtirotiro. He pai mō te whakamātautau i te whanonga headless me headful ki te whāinga kotahi.

Ka taea e Puppeteer te whakahaere i te mōhiti headful?

Āe. Ka taea e Puppeteer te whakatuwhera i a Chromium i te mōhiti headless, i te headful. Ka taea te awhina o te mōhiti headful i te wā e whakamātautau ana i ngā mahi e pā ana ki te whakawhiti, ki te tirotiro i te whanonga pūtirotiro.

Ahea me karo au i ngā pūtirotiro katoa?

Karo i ngā pūtirotiro i te wā e hoki ana ngā tono HTTP māmā ki ngā raraunga katoa, tika. He nui ake te utu o ngā pūtirotiro i ngā kaihoko HTTP, ā, me whakamahi i te wā e hiahiatia ana te whakatakotoranga JavaScript, te whakawhiti, rānei te āhua pūtirotiro.

He aha ngā paearu e whakaatu ana he mea nui te headful?

Tirohia ngā reiti angitu teitei, te hohonu whakahou iti, te ora wā roa, me te CPSR iti ahakoa te utu rorohiko teitei. Mēnā kāore e piki ēnei paearu, kāore pea e tika te whakawhānui i te headful.

He aha te whakaritanga pai mō te kohikohi raraunga hou?

Ko te whakaritanga pai he mea pātea. Whakamahia ngā kaihoko HTTP mō ngā pito māmā, ngā pūtirotiro headless mō te whakatakotoranga e taea te whakawhanake, me ngā pūtirotiro headful mō ngā mahi e pā ana ki te pūtirotiro e tino uaua ana.

Ngā Whakaaro Whakamutunga

Kāore e tika te tango i ngā pūtirotiro headless me headful hei whiringa pūmau. He whakaritenga te whakatau i runga i te uaua o te whāinga, te pēhanga fingerprint, te uara raraunga, me te utu.

Whakamahia te headless i te wā e pai ana. Whakamahia te headful i te wā e whakapai ana i te putanga tika i te nui e tika ana ki te utu tāpiri. Whakaritea te mōhiti pūtirotiro ki te momo proxy, te kaupapa wā, me ngā paearu tirotiro.

Mō te tautoko i te whakatinana, tirohia ngā tutorial proxy a SquidProxies me ngā take whakamahi proxy hei hono i te aunoa pūtirotiro ki te rautaki proxy e taea te whakaputa.
