Ukweqa umkhawulo wosesho lwe-LinkedIn ngokudlala nge-API

Umkhawulo

Kunomkhawulo onjalo ku-LinkedIn - Umkhawulo wokusetshenziswa kwezohwebo. Kungenzeka kakhulu ukuthi nawe, njengami kuze kube muva nje, awukaze uhlangane noma uzwe ngakho.

Ingqikithi yomkhawulo ukuthi uma usebenzisa usesho lwabantu abangaphandle koxhumana nabo kaningi (awekho amamethrikhi aqondile, i-algorithm inquma ngokusekelwe ezenzweni zakho - ukuthi useshe kangaki futhi kangakanani, wengeza abantu), bese kuba umphumela wosesho. izokhawulelwa kumaphrofayili amathathu, esikhundleni sika-1000 (amakhasi ayi-100 azenzakalelayo, amaphrofayili ayi-10 ngekhasi ngalinye). Umkhawulo usethwa kabusha ekuqaleni kwenyanga ngayinye. Ngokwemvelo, ama-akhawunti e-premium awanawo lo mkhawulo.

Kodwa kungekudala, ngephrojekthi yezilwane ezifuywayo, ngaqala ukudlala kakhulu ngosesho lwe-LinkedIn futhi ngokuzumayo ngathola lo mkhawulo. Ngokwemvelo, angizange ngikuthande kakhulu lokhu, ngoba angizange ngiyisebenzise noma yiziphi izinjongo zokuthengisa, ngakho-ke umcabango wami wokuqala kwakuwukufunda umkhawulo bese uzama ukuzungeza.

[Ukucaciswa okubalulekile: izinto eziku-athikili zethulwa kuphela ngezinjongo zolwazi nezemfundo. Umbhali akakukhuthazi ukusetshenziswa kwazo ngezinjongo zokuthengisa.]

Sifunda inkinga

Sine: esikhundleni samaphrofayili ayishumi ane-pagination, ukusesha kubuyisela amathathu kuphela, emva kwalokho ibhulokhi "enesincomo" se-akhawunti ye-premium ifakiwe futhi ngezansi kukhona amaphrofayili alufiphele futhi angachofozeki.

Ngokushesha, isandla sifinyelela kukhonsoli yonjiniyela ukuze sibheke lawa maphrofayela afihliwe - mhlawumbe singasusa izitayela ezithile ezifiphalisayo, noma sikhiphe ulwazi kubhulokhi kumakhaphu. Kodwa, ngokulindelekile, lawa maphrofayili alungile izithombe zokubamba indawo futhi akukho lwazi olugciniwe.

Kulungile, manje ake sibheke ithebhu Yenethiwekhi bese sibheka ukuthi eminye imiphumela yosesho ebuyisela amaphrofayili amathathu kuphela iyasebenza yini. Sithola isicelo esinentshisekelo kuso sokuthi "/api/search/blended" futhi sibheke impendulo.

Amaphrofayili afika ngohlelo `luhlanganisiwe`, kodwa sekunezinhlaka eziyi-15 kulo, ezintathu zokuqala ziyizinto ezinolwazi olwengeziwe, into ngayinye iqukethe ulwazi ngephrofayili ethile (isibonelo, noma ngabe iphrofayili iyiprimiyamu. ).

Ezilandelayo eziyi-12 zingamaphrofayili angempela - imiphumela yosesho, emithathu kuphela esizoyiboniswa. Njengoba usuvele uqagele, kukhombisa kuphela labo abathola ulwazi olwengeziwe (izinto ezintathu zokuqala). Isibonelo, uma uthatha impendulo kuphrofayili ngaphandle komkhawulo, uzothola izinhlangano ezingama-28 - izinto eziyi-10 ezinokungeziwe. ulwazi kanye namaphrofayili angu-18.

Phendula iphrofayela ngaphandle komkhawulo

Kungani kufika amaphrofayili angaphezu kwe-10, nakuba kucelwe i-10 ngqo, futhi abahlanganyeli noma iyiphi indlela ekubonisweni, ngisho nasekhasini elilandelayo ngeke abe khona - angazi okwamanje. Uma uhlaziya i-URL yesicelo, ungabona ukuthi count=10 (mangakhi amaphrofayili azobuyiselwa empendulweni, umkhawulo ongu-49).

Ngingajabula ukuthola noma yikuphi ukuphawula ngalolu daba.

Ake sizame

Kulungile, into ebaluleke kakhulu manje esiyazi ngokuqinisekile ukuthi kukhona amaphrofayli amaningi empendulweni kunaleyo asibonisa yona. Lokhu kusho ukuthi singathola idatha eyengeziwe, ngaphandle komkhawulo. Ake sizame ukudonsa i-API ngokwethu, ngqo kusuka kukhonsoli, sisebenzisa ukulanda.

Njengoba kulindelekile, sithola iphutha, 403. Lokhu kungenxa yokuphepha, lapha asithumeli ithokheni ye-CSRF (I-CSRF ku-Wikipedia. Kafushane, ithokheni eyingqayizivele yengezwa esicelweni ngasinye, ehlolwa kuseva ukuze kutholakale ubuqiniso).

Ingakopishwa kusuka kunoma yisiphi esinye isicelo esiphumelele noma kumakhukhi, lapho igcinwe khona emkhakheni we-'JSESSIONID'.

Ungathola kuphi ithokheniIsihloko sesinye isicelo:

Noma kusuka kumakhukhi, ngqo ngekhonsoli:

Ake sizame futhi, kulokhu sidlulisa izilungiselelo okufanele sizilande, lapho sicacisa ithokheni yethu ye-csrf njengepharamitha kunhlokweni.

Impumelelo, sithola wonke amaphrofayili ayi-10. :tada:

Ngenxa yomehluko kumaheda, ukwakheka kwempendulo kuhluke kancane kulokho okutholwa esicelweni sokuqala. Ungathola isakhiwo esifanayo uma wengeza okuthi 'Accept:'application/vnd.linkedin.normalized+json+2.1' entweni yethu, eduze nethokheni ye-csrf.
Isibonelo sempendulo enesihloko esengeziwe

Okuningi mayelana nesihloko esithi Yamukela

Yini okulandelayo?

Khona-ke ungakwazi ukuhlela (ngesandla noma ngokuzenzakalelayo) ipharamitha `yokuqala`, ekhomba inkomba, kusukela lapho sizonikezwa amaphrofayili angu-10 (okuzenzakalelayo = 0) kuwo wonke umphumela wosesho. Ngamanye amazwi, ngokuyikhulisa ngo-10 ngemva kwesicelo ngasinye, sithola okukhiphayo okujwayelekile kwekhasi nekhasi, amaphrofayili ayi-10 ngesikhathi.

Kulesi sigaba nginedatha eyanele nenkululeko yokuqhubeka nokusebenza kuphrojekthi yezilwane ezifuywayo. Kodwa bekuzoba yisono ukungazami ukuveza le datha khona lapho, ngoba ibivele ikhona. Ngeke singene ku-Ember, esetshenziswa ngaphambili. I-jQuery ixhunywe kusayithi, futhi ngemva kokukhipha ulwazi lwe-syntax eyisisekelo ememori, ungakha okulandelayo emizuzwini embalwa.

Uma wenza lokhu ngokuqondile kukhonsoli ekhasini lokusesha, izongeza inkinobho elayisha amaphrofayela amasha angu-10 ngokuchofoza ngakunye futhi iwanikeze ohlwini. Kunjalo, shintsha ithokheni ne-URL kube kwedingekayo ngaphambi kokwenza lokhu. Ibhulokhi yephrofayela izoqukatha igama, indawo, indawo, isixhumanisi sephrofayela kanye nesithombe sesibambi.

isiphetho

Ngakho, ngomzamo omncane, sakwazi ukuthola indawo ebuthaka futhi saphinde safuna ngaphandle kwemingcele. Kwanele ukuhlaziya idatha kanye nendlela yayo, bheka isicelo ngokwaso.

Angikwazi ukusho ukuthi lokhu kuyinkinga enkulu ye-LinkedIn, ngoba ayifaki usongo. Inzuzo enkulu elahlekile ngenxa yalezo "zokusebenza", ezikuvumela ukuthi ugweme ukukhokhela i-premium. Mhlawumbe impendulo enjalo yeseva iyadingeka ekusebenzeni okulungile kwezinye izingxenye zesayithi, noma kumane kuwubuvila babathuthukisi kanye nokuntuleka kwezinsiza ezingakuvumeli ukuthi kwenziwe kahle. (Umkhawulo uvele ngoJanuwari 2015; ngaphambi kwalokhu kwakungekho mkhawulo).

PS

Ngokwemvelo, ikhodi ye-jQuery iyisibonelo sakudala samakhono. Okwamanje ngidale isandiso sesiphequluli esifanelana nezidingo zami. Yengeza izinkinobho zokulawula futhi inikeze amaphrofayili agcwele anezithombe, inkinobho yesimemo nokuxhumana okuvamile. Futhi, iqoqa ngamandla izihlungi zezindawo, izinkampani, nezinye izinto, futhi ithola ithokheni kumakhukhi. Ngakho-ke asikho isidingo sokwenza i-hardcode noma yini. Yebo, yengeza izinkambu zezilungiselelo ezengeziwe, elithi "mangaki amaphrofayili ongawacela ngesikhathi, kuze kufike ku-49."

Ngisalungisa lokhu kwengezwa futhi ngihlela ukukudedela emphakathini. Bhala uma unentshisekelo.
