Layanan Lokasi GSM tina modul SIM800x sareng karyana sareng Yandex.Locator API

Google, hanjakalna keur loba pamaké modul GSM, 2-3 sababaraha bulan kapengker diblokir sarta ditransfer ka dasar dibayar API pikeun nangtukeun lokasi dumasar kana koordinat munara sél katempo modul. Kusabab ieu, on SIM800 modul runtuyan dihasilkeun Leyuran Wireless SIMCom, pungsionalitas paréntah AT + CIPGSMLOC eureun gawé. Dina tulisan ieu kuring bakal nyarioskeun ka anjeun kumaha anjeun tiasa ngabéréskeun masalah ieu nganggo jasa anu sami anu disayogikeun ku Yandex - Yandex.Locator.

Hayu urang skip kumaha Yandex narima koordinat tina munara sél, hal utama nyaéta yén urang bisa ngagunakeun layanan bébas ieu tur meunangkeun data handap: Lintang, Bujur, Altitude, kitu ogé kasalahan perkiraan pikeun tiap parameter. Tujuan utama tulisan nyaéta pikeun masihan tutorial pondok ngeunaan gancang ngalih kana API Yandex, tinimbang jasa anu henteu aya deui ti Google.

Di handap, sabagé conto, urang ngan ukur nunjukkeun lintang sareng bujur lokasi modul.

Ku kituna hayu urang ngamimitian

Mimiti anjeun kedah maca perjanjian pangguna anu aya di: yandex.ru/legal/locator_api. perhatian husus kudu dibayar ka klausa 3.6. perjangjian pamaké ieu, nu nyatakeun yén Yandex ngagaduhan hak pikeun ngarobih/ngalereskeun atanapi ngapdet Yandex.Locator API iraha waé, tanpa aya bewara sateuacanna..

Pindah ka alamat yandex.ru/dev/locator/keys/get sareng tambahkeun akun Yandex anjeun sateuacana ka grup pamekaran. Léngkah ieu bakal ngamungkinkeun anjeun kéngingkeun konci pikeun ngaksés jasa ieu.

Saatos ngalengkepan léngkah-léngkah ieu, anjeun bakal ngagaduhan aksés kana halaman éta yandex.ru/dev/locator/doc/dg/api/geolocation-api-docpage dimana inpormasi dasar ngeunaan mékanisme operasi jasa Yandex.Locator disayogikeun.

Pikeun ngahasilkeun pamundut XML dina format cURL kana jasa Yandex.Locator, anjeun kedah kéngingkeun inpormasi ngeunaan menara sél "katingali" ku modul:

• kode nagara - kode nagara
• operatorid - kode jaringan mobile
