放置自动填充API以从输入的地址获取GPS坐标

Question

我的应用程序中有一个地址字段,用户需要输入所需的地址.我使用谷歌地理编码器来获取地址的GPS坐标.但现在我想通过使用地方自动填充功能让用户更轻松.但地方自动填充仅返回地点的地址,ID和地点.

有没有办法使用Places Autocomplete API获取用户选择的地址的GPS坐标？用户从"地方自动填充"中选择地址后,是否必须再次使用地理编码器？

或者,在用户选择地址以获取地址的GPS坐标后,我是否应该再次使用Places API？由于使用限制,我不想向Places API发送多个请求..这是Places API的预期响应.响应中没有GPS坐标.

Answer 1

您只需使用Places API 的Place Details部分,您可以使用"reference"值从每个建议中的引用中获取实际位置.例如:

https://maps.googleapis.com/maps/api/place/details/json?reference=CiQYAAAA0Q_JA...kT3ufVLDDvTQsOwZ_tc&sensor=true&key=AddYourOwnKeyHere

这将为您提供有关该地点的信息,包括其坐标(特定位置的点,区域的边界).
