🥇Nekupfuura LinkedIn yekutsvaga muganhu nekutamba neAPI

Ganhurira

Pane kudzikisira kwakadaro paLinkedIn - Muganho wekushandiswa kwekutengesa. Zvinonyanya kuitika kuti iwe, seni kusvika nguva pfupi yadarika, hauna kumbobvira wasangana nazvo kana kunzwa nezvazvo.

Izvo zvakakosha zvemuganho ndezvekuti kana iwe ukashandisa kutsvaga kwevasiri vaunosangana navo kakawanda (hapana chaiwo metrics, iyo algorithm inosarudza zvichibva pane zvaunoita - kangani uye zvakadii watsvaga, wakawedzera vanhu), ipapo mhedzisiro yekutsvaga. ichaganhurwa kumaprofiles matatu, pachinzvimbo che1000 ( default 100 mapeji, 10 profiles papeji). Muganhu unoiswa patsva pakutanga kwemwedzi wega wega. Sezvingatarisirwa, premium account haina ichi chinogumira.

Asi nguva pfupi yapfuura, yepurojekiti yemhuka, ndakatanga kutamba zvakanyanya neLinkedIn yekutsvaga uye ndakangoerekana ndawana muganhu uyu. Nomuzvarirwo, ini handina kufarira izvi zvakanyanya, nekuti ini handina kuishandisa kune chero chinangwa chekutengesa, saka pfungwa yangu yekutanga yaive yekudzidza iyo inogumira uye kuyedza kuitenderedza.

[Tsanangudzo yakakosha: zvinyorwa zviri muchinyorwa zvinoratidzwa chete nekuda kweruzivo uye zvekudzidzisa zvinangwa. Munyori haakurudzire kushandiswa kwavo kwezvinangwa zvekutengesa.]

Tiri kudzidza dambudziko

Tine: pachinzvimbo chegumi maprofayiri ane pagination, iyo yekutsvaga inodzoka matatu chete, mushure mezvo bhuroka rine "kurudziro" yeprimiyamu account inoiswa uye pazasi ine blurry uye isingabatike profiles.

Pakarepo, ruoko runosvika kune mugadziri wekoni kuti atarise aya akavanzika maprofile - pamwe tinogona kubvisa mamwe masitayipi ekufinyama, kana kubvisa ruzivo kubva mubhuroka mune markup. Asi, zvinonyatsotarisirwa, aya maprofile angori placeholder mifananidzo uye hapana ruzivo rwakachengetwa.

Zvakanaka, ikozvino ngatitarisei kune Network tab uye titarise kana imwe mhinduro yekutsvaga inodzosera maprofile matatu chete inoshanda. Isu tinowana chikumbiro chatinofarira che "/api/search/blended" uye tarisa mhinduro.

Maprofiles anouya mune `akasanganisirwa` array, asi atove nemasangano mairi 15. Muchiitiko ichi, matatu ekutanga acho zvinhu zvine rumwe ruzivo, chinhu chimwe nechimwe chine ruzivo pane chaiyo profil (semuenzaniso, kana iyo profil iri premium. )

Iwo gumi nemaviri anotevera maprofiles chaiwo - mitsva yekutsvaga, iyo mitatu chete icharatidzwa kwatiri. Sezvo iwe unogona kutofungidzira, inoratidza chete avo vanogamuchira rumwe ruzivo (zvinhu zvitatu zvekutanga). Semuenzaniso, kana iwe ukatora mhinduro kubva kuprofile pasina muganho, iwe unogashira 12 masangano - gumi zvinhu nekuwedzera. ruzivo uye 28 profiles.

Pindura chimiro pasina muganhu

Nei anopfuura gumi profiles achisvika, kunyangwe gumi chaiwo akakumbirwa, uye ivo vasingatore chikamu mukuratidzira nenzira ipi neipi, kunyangwe pane rinotevera peji havazove - ini handisati ndaziva. Kana iwe ukaongorora iyo URL yekukumbira, unogona kuona iyo count=10 (mangani maprofile ekudzoka mumhinduro, anodarika makumi mana nemapfumbamwe).

Ndingafara kugamuchira chero mhinduro panhau iyi.

Ngatiedzei

Zvakanaka, chinhu chinonyanya kukosha chatinoziva chokwadi ndechekuti kune mamwe maprofile mumhinduro pane yavanotiratidza. Izvi zvinoreva kuti tinogona kuwana data rakawanda, kunyangwe muganhu. Ngatiedzei kudhonza iyo API isu pachedu, zvakananga kubva kune iyo console, tichishandisa kutora.

Sezvinotarisirwa, tinowana kukanganisa, 403. Izvi zvinokonzerwa nekuchengeteka, pano isu hatisi kutumira chiratidzo cheCSRF (CSRF paWikipedia. Muchidimbu, chiratidzo chakasiyana chinowedzerwa kune chimwe nechimwe chikumbiro, icho chinotariswa pane sevha yechokwadi).

Inogona kukopwa kubva kune chero chimwe chikumbiro chakabudirira kana kubva kukiki, kwainochengetwa mundima ye 'JSESSIONID'.

Kwaungawane chiratidzoMusoro wechimwe chikumbiro:

Kana kubva kukiki, zvakananga kuburikidza nekoni:

Ngatiedzei zvakare, panguva ino tinopfuudza marongero ekutora, umo tinotsanangura yedu csrf-chiratidzo separameter mumusoro.

Kubudirira, tinogashira ese gumi profiles. :tada:

Nekuda kwekusiyana kwemisoro, chimiro chemhinduro chakati siyanei nezvakagamuchirwa muchikumbiro chekutanga. Unogona kuwana chimiro chimwe chete kana ukawedzera 'Gamuchira:'application/vnd.linkedin.normalized+json+2.1' kune chinhu chedu, padivi pe csrf tokeni.
Muenzaniso mhinduro ine musoro wakawedzerwa

Chii chinotevera?

Ipapo iwe unogona kugadzirisa (nemaoko kana automate) iyo `kutanga` parameter, inongedza kune index, kubva patichapihwa gumi profiles (default = 10) kubva pane yese yekutsvaga mhinduro. Mune mamwe mazwi, nekuiwedzera negumi mushure mekukumbira kwega kwega, tinowana yakajairika peji-ne-peji kuburitsa, gumi profiles panguva.

Panguva ino ndaive nedata yakakwana uye rusununguko rwekuenderera mberi nekushanda pachirongwa chepet. Asi chingadai chiri chivi kusaedza kuratidza iyi data ipapo ipapo, sezvo yaive yatovepo. Hatisi kuzopinda muEmber, iyo inoshandiswa kumberi. jQuery yaive yakabatana nesaiti, uye wachera kunze ruzivo rwekutanga syntax mundangariro, unogona kugadzira zvinotevera mumaminetsi akati wandei.

(Muganho wakaonekwa muna Ndira 2015; izvi zvisati zvaitika pakanga pasina muganhu).

PS

Nomuzvarirwo, iyo jQuery kodhi muenzaniso wekare wekugona. Parizvino ndagadzira browser yekuwedzera kuti ikwane zvandinoda. Iyo inowedzera mabhatani ekudzora uye inopa yakazara maprofile nemifananidzo, bhatani rekukoka uye zvakabatana zvinongedzo. Uyezve, inounganidza zvine simba mafirita enzvimbo, makambani, uye zvimwe zvinhu, uye inotora chiratidzo kubva kukiki. Saka hapana chikonzero che hardcode chero chinhu zvakare. Zvakanaka, inowedzera mamwe masisitimu ekuwedzera, iyo "mangani maprofiles ekukumbira panguva, kusvika makumi mana nemapfumbamwe."

Ndichiri kushanda pakuwedzera uku uye ndinoronga kuiburitsa kune veruzhinji. Nyora kana uchifarira.
