Te Mārama i te Pūtahi Proxy i te Tīwhiri

Ka taea e te scraper te whai i te parser tika, te rārangi whāinga tika, me te nui o ngā proxy—ā, kāore e taea te rongo i te tere, te pumau, i te mea kāore e taea te utu. I te nuinga o ngā wā, ko te take huna ko te proxy network latency. Ka piki te latency, ka roa ngā whakamātau, ka heke te throughput, ā, ka raru te whai hua o ngā raraunga e pā ana ki te wā.

Ko te mea ka riro mai i konei he aratohu whaihua mō te tikanga o te latency proxy, ko te take e pā ana ki a ia, me pēhea e pā ana ki te whakaritenga scraping, me ngā mea hei ine i mua i te huri i tō whakaritenga.

Proxy network latency ko te whakaroa i waenga i te tuku i tētahi tono mā te proxy me te whiwhi i te whakautu tuatahi whaihua mai i te whāinga. I roto i te scraping, ka heke te throughput i te piki o te latency, ka piki te wā rārangi, ā, ka piki te utu o ia hua e taea te whakamahi.

He aha te take e nui ai te latency i te nuinga o ngā tīma scraping e tumanako ana

He maha ngā tīma e aro ana i te tuatahi ki te reiti aukati, te momo proxy, me te huri. He mea nui ēnei, engari ka taea e te latency te whakarereke i te pūtea o te paetahi katoa.

Mēnā ka roa te tango o ia tono, ka kohi te pūnaha i ngā tuhinga iti ake i ia kaimahi, ka noho te wāhanga mō te wā roa, ā, ka piki te maha o ngā timeout. Ko te tikanga, ko te mahi scraping kotahi ka hiahia pea ki te nui ake o te rorohiko, te maha o ngā whakamātau, me te nui ake o te pātea hei pupuri i te putanga kotahi.

Koinei te take kotahi e hiahia ai ngā proxy use cases rerekē i ngā tumanakohanga mahi rerekē. Ko tētahi kaiwhakahaere utu me ngā wā whakahou poto e pā ana ki te latency i te mea he mea nui atu i te huri i ngā whārangi iti te hiranga i te wiki.

He aha ngā mea e pā ana ki te proxy network latency

Ehara te latency i te mea kotahi. Ko te whakaroa katoa i whakauruhia i ngā mahi maha i te ara tono.

Ka taea te whakauru i:

• te wā hono ki te proxy
• te wā whakawhiti i te proxy ki te whāinga
• te wā handshake TLS
• te whakaroa whakautu mai i te whāinga
• te whakaroa whakawhiti mō ngā raupapa whaihua tuatahi

I ngā kupu māmā: ko te latency te wā e noho ana tō pūnaha e tatari ana i mua i te taea te mahi whaihua.

He aha te take e piki ai te latency proxy i roto i ngā pūnaha scraping pono

Te tawhiti ā-rohe

Mēnā ka tawhiti te tono e haere ana, ka roa te hokinga mai.

Mēnā kei te rohe kotahi te proxy, ā, kua whakaritea te whāinga mō tētahi atu, ka piki te latency. He mea nui tēnei i te wā e pā ana ana te whāinga ki te noho pōturi, ki te wā whakautu e pākiki ana.

Te momo proxy me te ara whatunga

Ka taea e ngā momo proxy rerekē te whakauru i ngā pūnaha mahi rerekē.

Datacenter proxies he mea nui te tuku i te latency iti mō te kohinga nui i te mea he mea hanga mō te tere me te rahi. Residential proxies ka taea te whakauru i te latency teitei ake, te rerekē hoki, i te mea ka whakawhiti i ngā whatunga kaihoko pono.

Ehara tēnei i te mea he pai ake te kotahi. Ko te tikanga, me ine te latency ki te uara o te whāinga, ngā hiahia wāhanga, me te reiti angitu.

Te pātea o te pūnaha

Mēnā ka nui te waka i te rōpū proxy kotahi, ka piki te latency i mua i te mōhio o ngā reiti aukati.

Ka kitea tēnei hei wā e pā ana ana te wā whakautu, te teitei o te rārangi, me te rerekētanga o te whakatutukitanga mahi.

Ngā mahi e pā ana ki ngā wāhanga

Ko te scraping e pā ana ki te rehita, te haere, me ngā mahi e whakahaerehia ana e te pūtirotiro ka piki te wā whakautu katoa.

I ngā take pēnei, ehara te latency i te whakaroa whatunga anake. Ka whakaatu hoki i te roa e pupuri ana te hangarau i te ara ki te whakatutuki i tētahi mahi.

Te whakaritenga tono kāore e tika ana

Ahakoa he tere te proxy, ka taea te rongo i te pōturi mēnā kāore e tika te wā o ngā tono.

Ka taea e te waka nui, te rahi o te rārangi, me ngā whakamātau kāore e tika ana te piki i te latency e kitea ana o te pūnaha.

Me pēhea te pānga o te latency ki te whakatutuki scraping i roto i te mahi

He mea nui te latency nāna i whakarereke te nui o te mahi ka taea e tō hangarau te whakaoti i te wā e wātea ana.

He pānga rongonui:

• he iti ake te throughput mō ia kaimahi
• he roa ake ngā wā rārangi
• he nui ake ngā timeout i ngā whāinga pōturi
• he iti ake te whakahou mō te kohinga e pā ana ki te wā
• he nui ake te utu rorohiko mō ia tuhinga angitu

Mēnā he paipa e kohi ana i ngā utu, te wātea, i ngā raraunga e pā ana ki te wā, ka taea e ēnei whakaroa te whakaiti i te uara o te hua ahakoa e angitu ana te tono i te hanganga.

He mea nui tēnei mō ngā rōpū e whakamahi ana i te web scraping proxies i ngā momo rautaki rerekē me ngā whanonga urupare rerekē.

He aha te ahua o te paerewa whakaroa pai

Kāore he tau whakaroa "pai" e taea te whakamahi i ngā whakaritenga katoa mō te tango raraunga. Ko te paerewa tika e whakawhirinaki ana ki te whāinga, te mahi, me ngā whakaritenga pakihi.

He pai ake te huarahi ko te whakatau i te paerewa e pā ana ki te momo puna:

I ngā kupu māmā: he pai te whakaroa iti, engari anake mēnā ka whakaputa tonu i ngā hua pumau, e taea te whakamahi.

Me pēhea te ine i te whakaroa o te whatunga proxy i te tika

Kaua e whakawhirinaki ki te tau toharite anake.

I te iti rawa, tirohia:

• te whakaroa toharite
• te whakaroa p95
• te reiti waehanga
• te wā ki te tuhinga tuatahi
• te reiti angitu tono i te momo proxy
• te whakaroa i te rohe, i te ara

Ka kōrero te toharite ki a koe mō te take noa. Ka kōrero te p95 mō te āhua o te rerenga tino pātea. He mea nui tēnei nāna i te mea ka raru ngā pūnaha tango raraunga i ngā pito i mua i te mea ka kino ngā toharite.

Te āhuatanga o te ao: te tirotiro i ngā hua i ngā whāinga rerekē

Whakaarohia he rōpū e tirotiro ana i te putanga me ngā utu i runga i te rōpū nui o ngā paetukutuku hoko. Ka taea e ngā whārangi kāwai tūmatanui te mahi tere i runga i ngā ara pokanga.

Engari, ka pā te mahi ki ngā utu hātepe, ki ngā whārangi pūtea e pā ana ki te wāhi, ka taea te pikinga o te wā urupare, ina koa mēnā ka huri te ara ki ngā rerenga kāinga. Kāore te rongoā i te mea ko te whakakāhoretanga o ngā proxy tere. He maha ngā wā ka hiahiatia te wehewehe i te mahi kia whakamahia ngā ara iti te whakaroa mō ngā whārangi māmā, ā, ko ngā whārangi pātea e whakamahi ana i ngā ara kaha ake.

Ka noho te paipa i te paerewa, kaua e kaha te whakamahi i te paerewa whakaroa ki ngā momo whārangi katoa.

Kia tūpato ki tēnei

Te whai i te tere me te kore e tirohia te kounga hua

Kāore he painga o te whakaroa iti mēnā ka heke te reiti angitu, kāore e hoki mai ngā whārangi i ngā raraunga kāore e oti.

Te tirohia anake ngā toharite

Ka taea e te whakaroa toharite te huna i te puku, te kore e noho pūmau e pā ana ki te pāmahana me te matomato.

Te whakakotahi i ngā whāinga rerekē i roto i te paerewa kotahi

Ka raru ngā hua whakaroa mēnā ka inehia ngā whārangi tūmatanui me ngā mahi tiakina i te taha kotahi me te kore e wehewehe.

Te whakamahi i ngā proxy kāinga i reira e nui ana te hiahia ki te tere

Ka taea e ngā ara kāinga te whakapai ake i te uru ki ngā whāinga uaua, engari ka taea e rātou te whakaroa. Whakamahia ēnā i reira e tika ana te whakawhiti.

Te hē i te whakaroa rārangi hei whakaroa whatunga

I ētahi wā, he pai te proxy, ā, ko te rārangi whakahaere te tino raru.

Me pēhea te whakaiti i te whakaroa me te kore e hanga raru hou

Whakaritea te momo proxy ki te mahi

Mēnā he pātea, he iti te aukati, ka taea e ngā ara pokanga tere te rīrangi.

Mēnā he pātea, e pā ana ki te whenua, ki te hātepe, ka taea e ngā ara kāinga te pai ake ahakoa he teitei ake te whakaroa. Ko te whāinga kāore e noho hei ara tere i te wā anake. Ko te whāinga ko te ara pai mō ngā hua e taea te whakamahi.

Kia mau ki te whenua

Kia mau ki te wāhi proxy e tata ana ki te whāinga, ki te rohe e tūmanakohia ana.

Ka taea tēnei te whakaiti i te wā whakawhiti me te whakapai ake i te pūmau o te whenua i te wā kotahi.

Wehewehe i ngā ara e pā ana ki te whanonga puna

Kaua e kaha te whakamahi i te paerewa whakaroa kotahi i runga i ngā whāinga katoa.

Wehewehe:

• ngā pito tūmatanui
• ngā mahi taki
• ngā whārangi e pā ana ki te whenua
• ngā whāinga teitei te aukati

Ka taea e koe te whakarite i te whakaroa i roto i ēnei rōpū, kaua e whakataurite i ngā mahi rerekē.

Tūtohu te pāmahana i te tika

Mēnā he teitei rawa te pāmahana, ka taea e te whakaroa rārangi me te kore e noho pūmau te whakaroa te ahua kino atu i te mea e tika ana.

Ko te whakaiti i te whakakotahi i runga i te whāinga ngoikore i etahi wa ka whakapai ake i te raru me te reiti angitu.

Tangohia ngā huarahi ngoikore i te tere

Ka noho ngā huarahi ki te pātea i mua i te mea ka kitea te kino.

Tirohia te huringa raru e pa ana ki te rōpū proxy, ā, kāore e taea te whakaiti i ngā huarahi e noho ana ki te raru i mua i te pikinga o ngā reiti aukati.

Raru, utu, me te whakamahere āheinga

Ko te raru he take pūtea hoki.

Mēnā ka roa ngā tono, ka hiahia pea koe ki te nui ake o ngā kaimahi, te wā pātea i runga i te tirohanga, me ngā huihuinga aktīve hei kohi i te rahinga o ngā raraunga. Ka piki tēnei i te utu whaihua ahakoa kei te noho tonu te utu proxy.

Koia te take me tirohia te raru i te taha ki ngā arahi proxy whānui pērā i te rārangi, te momo proxy, me te whakahaere huihuinga, kāore hei paerewa anake.

He pānga whaihua hei tirohia:

utu mō ia tuhinga angitu = te katoa o ngā whakapaunga e pā ana ki ngā tono / ngā tuhinga kohikohi tika

I ngā kupu māmā: te utu i utua e koe mō ia hua e taea ana i muri i te whakaritenga mō ngā huarahi pōturi, ngā whakahou, me ngā waea kāore e taea.

Kahea ki te tirohia anō ō whakaritenga raru

Tirohia tō whakaritenga ka kite koe:

• te tere e pātea ana kāore he pikinga nui o te waka
• te nui ake o ngā waea kāore e taea i runga i ngā wāhi kotahi
• te wā pātea i runga i ngā mahi kotahi
• te pikinga o te raru p95 ahakoa ko te pokanga e noho ana ki te pūmau
• te pikinga o te utu kāore he pai ake te whakahou, te pokanga, rānei

Ko ēnei tohu e mōhiotia ana hei tohu kei te noho te raru hei take hangarau, kāore hei tatauranga i te taha.

Ngā Pātai e Pātaihia Ana

He aha te raru o te whatunga proxy i roto i te kohikohi?

Ko te raru te rerekētanga i waenga i te tuku tono mā te proxy me te tiki i te whakautu whaihua tuatahi. I roto i te kohikohi, ka pā te raru ki te pātea, te raru waea, me te whaihua o te pūnaha katoa.

He iti ake te raru o ngā proxy pokanga i ngā proxy kāinga?

He maha ngā wā, engari kāore i ia wā. Ko ngā proxy pokanga he mea hanga hei tere, i te mea ko ngā proxy kāinga ka whakawhiti i ētahi tere mō te tino pono me te whai wāhi pai i runga i ngā whāinga tiakina.

Me whakapai au mō te raru iti rawa?

Kāore e taea anake. He pai te raru iti anake mēnā ka noho pūmau te reiti angitu me te kounga raraunga. Ko te whāinga pai ko te whakaritenga pai i waenga i te tere, te pono, me te utu.

He aha te pānga e nui ake ana: te raru pokanga, te raru p95?

E rua e pā ana. Ko te pokanga e whakaatu ana i tō mahi noa, i te mea ko te p95 e whakaatu ana i te taha pōturi e kawe ana i ngā waea kāore e taea me te pikinga o te rārangi.

Ka taea e te raru te piki i te utu kohikohi ahakoa he iti ngā utu proxy?

Āe. Ka whakaiti ngā huarahi pōturi i te pātea, ka noho ngā kaimahi ki te mahi mō te wā roa, ā, ka piki pea ngā whakahou. Ka piki tēnei i te utu whaihua o ia tuhinga e taea ana.

E hia ngā wā e tika ana hei whakamātautau i te raru i runga i te huarahi, te puna?

I ngā wā e tika ana hei hopu i te huringa i mua i te pānga ki te putanga. Mō ngā hōtaka kohikohi aktīve, ko te tirotiro i te raru i runga i te puna i te wā o ia huringa nui he pai tonu hei paerewa.

Ngā whakaaro whakamutunga

Ko te whakahaere i te rārangi whatunga proxy he mea kāore e pā ana ki te whai i te tau iti rawa. He mea e pā ana ki te mōhio ki te wā e pāngia ai te raru ki te putanga, ā, ka whakakotahi i te hoahoa huarahi ki ngā hiahia o te mahi.

Mēnā ka rongo koe ko tō pūnaha e noho ana ki te pātea, kāore e tino hou, kāore e tino utu i te mea e whakaarohia ana, tīmatahia mā te inoi i te raru i runga i te momo puna, te momo proxy, me te huarahi. Ka kitea tēnei i te nuinga o te wā mēnā ko te raru tūturu kei te huarahi whatunga, te rārangi whakahaere, rānei ko te rōpū mahi anake.
