无法从公开的谷歌日历 API v3 获取活动

Question

按照本教程 http://www.androidhive.info/2012/01/android-json-parsing-tutorial，我对其进行了调整，以使用此URL"https://www.googleapis.com/calendar/v3/calendars/[calendar_ID]/events？singleEvents=true&orderBy=startTime&key=[my_API_key]"而不是示例中的URL来解析公共Google日历。此日历是公开的。

当我执行应用程序时，响应是这样的：

{
 "error": {
  "errors": [
   {
    "domain": "usageLimits",
    "reason": "accessNotConfigured",
    "message": "Access Not Configured. The API is not enabled for your project, or there is a per-IP or per-Referer restriction configured on your API key and the request does not match these restrictions. Please use the Google Developers Console to update your configuration.",
    "extendedHelp": "https://console.developers.google.com"
   }
  ],
  "code": 403,
  "message": "Access Not Configured. The API is not enabled for your project, or there is a per-IP or per-Referer restriction configured on your API key and the request does not match these restrictions. Please use the Google Developers Console to update your configuration."
 }
}

问题出在哪里？我做错了什么？

Answer 1

最后我找到了解决方案。

在这个URL https://www.googleapis.com/calendar/v3/calendars/[calendar_ID]/events？singleEvents=true&orderBy=startTime&key=[my_API_key]中，我使用的是Android应用程序的API密钥。当我为浏览器的 API 密钥更改此密钥时，问题消失了。
