google-maps-api-3 - 来自 Amazon EC2 的地理定位请求

Question

我正在部署一个向 Google Maps Geolocation API 发出请求的应用程序。我的请求从我的工作站顺利通过。但是每次我从亚马逊云中的服务器运行它时，我都会收到 400 Bad Request 错误。

下面是我要测试的示例 curl 请求。使用中的 API 允许任何 IP。

curl -d "{'wifiAccessPoints':[{'macAddress':'c8:d7:19:16:3b:63'},{'macAddress':'c8:d7:19:16:3b:61'}]}" -H "Content-Type: application/json" -i "https://www.googleapis.com/geolocation/v1/geolocate?key=PUTYOURKEYHERE" -v

以下是错误结果的示例

Answer 1

我遇到了完全相同的问题，出于某种原因，我遇到了相同的问题 curl命令可以在 ubuntu 上运行，但不能在 amazon ami (centos) 上运行。
解决方案是添加 considerIp: false到请求正文，如下所示:

{
    "considerIp": false,
    "wifiAccessPoints": [
        ...
    ]
}
