google-maps - 在哪里放置 Google Geocoding API 的 API key ？

Question

我们使用 Google Geocoding API将地址映射到纬度和经度。

这是编码的示例 URL(返回 json)-

http://maps.googleapis.com/maps/api/geocode/json?address=Dallas&sensor=false

消息:OVER_QUERY_LIMIT

好的，这是有道理的，因为我们超过了 2500 个每日限制，所以我们像这样放置 API key -

http://maps.googleapis.com/maps/api/geocode/json?key=xxxxx&address=Dallas&sensor=false

消息:REQUEST_DENIED

我想知道在哪里/如何放置 API key 。

Answer 1

看起来在版本 3 中你需要通过 ClientID在 URL 中而不是 key就像您在免费版本中所做的那样:https://developers.google.com/maps/articles/v2tov3#newkey

所以你的 URL 应该是这样的:http://maps.googleapis.com/maps/api/geocode/json?client=xxxxx&address=Dallas&sensor=false

不太幸运有付费帐户，所以我无法测试 - 但我认为这会让你走上正确的道路。

Client ID

You must include your client ID in all API requests. Your client ID identifies you as a Maps API for Business customer and enables support and purchased quota for your application. Requests made without a client ID are not eligible for Maps API for Business benefits.

If you're switching from the free API services to a Maps API for Business implementation, you must remove the key parameter from your requests. Google Maps API web services will deny requests made with both a client ID and a key.

More information is available in the Authentication and Authorization chapter of this guide.

If you have lost your client ID, you can recover it by logging in to the support portal and clicking Maps: Add URLs from the links on the left of the page.
