Isebenza njani iGeolocation yesikhangeli?

Sonke sibonile i-pop-up: "example.com ifuna ukwazi indawo okuyo." Ukuba ucofa u-Vumela, iwebhusayithi isoloko ikhomba eyona ndawo ukuyo kwimizuzwana nje. Kodwa ukuba usebenzisa ilaptop ngaphandle kwetshiphu yeGPS, yazi njani apho ukuyo ngokuchanekileyo?

I-HTML5 Geolocation API

Izikhangeli zewebhu zanamhlanje zisebenzisa umgangatho obizwa ngokuba yiHTML5 Geolocation API. Le API ayifumani indawo yakho ngokwayo; kunoko, lisebenza njengomthunywa. Icela inkqubo yokusebenza yesixhobo (iWindows, macOS, iOS, Android) ukuba ifumanise ukuba iphi, kwaye emva koko idlulise ezo zilungelelanisi zibuyela kwiwebhusayithi.

Indlela iNkqubo yokuSebenza ikufumana ngayo

Isixhobo sakho sisebenzisa indibaniselwano yeendlela ukumisela indawo ekuyo, eyaziwa ngokuba ziiNkonzo zeNdawo. Iza kuzama ezona ndlela zichanekileyo kuqala, kwaye ibuyele kwezona zingachanekanga kangako ukuba kuyimfuneko:

1. GPS: Ukuba ukwi-smartphone ngaphandle, isixhobo siya kusebenzisa i-GPS chip eyakhelweyo ukunxibelelana neesathelayithi. Le yeyona ndlela ichanekileyo.
2. I-Wi-Fi Positioning System (WPS): Ukuba ukwilaptop, le yeyona ndlela ixhaphakileyo. Ikhompyuter yakho ijonga zonke iinethiwekhi zeWi-Fi ezikufutshane (naleyo ungaqhagamshelwanga kuyo). Ithumela amagama (SSIDs) kunye namandla omqondiso kwezi intanethi kwisiseko sedatha (ehlala ilawulwa nguGoogle okanye i-Apple). Ngenxa yokuba ezi nkampani zenze imephu yeendawo zezigidi zeerutha ze-Wi-Fi kwihlabathi jikelele, ziyakwazi ukwenza unxantathu kwindawo yakho ngokuchaneka okothusayo-kaninzi ngaphakathi kweemitha ezimbalwa.
3. I-Cell Tower Triangulation: Kwizixhobo eziphathwayo, i-OS inokumisela indawo okuyo ngokusekwe kumgama wakho ukusuka kwiitower zeseli ezikufutshane.
4. Idilesi ye-IP: Ukuba konke okunye akuphumeleli, inkqubo iya kubuyela ekusebenziseni idilesi yakho ye-IP ukuqikelela isixeko okanye ummandla wakho.

Iimpembelelo zabucala

Ngenxa yokuba i-geolocation yesikhangeli ichanekile (enkosi kwi-Wi-Fi scanning), iibhrawuza ziyilelwe ukuba zingaze zabelane ngolu lwazi ngaphandle kwemvume yakho ecacileyo, yokungena. Ukuba uyala imvume yewebhusayithi, i-Geolocation API iya kuvala isicelo, kwaye indawo kuya kufuneka ibuyele ekuqikeleleni indawo yakho ngedilesi ye-IP endaweni yoko.
