Взаимодействие с API геолокации Yandex и Google

Имея учётную запись в Yandex и Google, можно получить ключ для доступа к API сервисов геолокации. Что с ними делать далее в замтке.

На сервере, к имени которого привязан ключ, размещаем скрипт следующего содержания:

переменным yandex_api_key и google_api_key нужно прописать соответствующие ключи доступа, в переменную keys — ключи клиентов.

Для определения координат нужно сделать следующий GET-запрос: https://mysite/geoapi?key=apikey&provider=yandex&mcc=250&mnc=99&lac=220000&cellid=330000&signal=-81, меняя переменную provider, можно выбрать поставщика услуг геолокации. В ответ сервер вернёт JSON-объект с данными о местоположении:

{"status":true,"lat":XX.XXXXXXX,"lng":YY.YYYYYYY,"precision":3201,"url":"https:\/\/maps.yandex.ru\/?ll=YY.YYYYYYY,XX.XXXXXXX&pt=YY.YYYYYYY,XX.XXXXXXX&spn=0.05,0.05&l=sat,skl"}

1	{"status":true,"lat":XX.XXXXXXX,"lng":YY.YYYYYYY,"precision":3201,"url":"https:\/\/maps.yandex.ru\/?ll=YY.YYYYYYY,XX.XXXXXXX&pt=YY.YYYYYYY,XX.XXXXXXX&spn=0.05,0.05&l=sat,skl"}
