我正在使用 Bingmaps API 来获取纬度和经度的 AdminDistrict 和 CountryRegion。它可以在浏览器中输入此网址：

http://dev.virtualearth.net/REST/v1/Locations/-30,-70/?includeEntityTypes=AdminDivision1,CountryRegion&o=xml&c=es-ES&key= myBingmapsApiKey

但是在 WP7 上的 C# 中，我无法让它工作。这是代码：

string wsUrl = "http://dev.virtualearth.net/REST/v1/Locations/-30,-70/?includeEntityTypes=AdminDivision1,CountryRegion&o=xml&c=es-ES&key=*myBingmapsApiKey*";

var request = new RestSharp.RestRequest(Method.GET);
var client = new RestSharp.RestClient(wsUrl);

try
{
    RestSharp.RestResponse resource;
    client.ExecuteAsync(request, (response) =>
    {
        resource = response;
        string content = resource.Content;
        string status_code = resource.StatusCode.ToString();
        string response_status = resource.ResponseStatus.ToString();
    });
}
catch (Exception e)
{
    string error = "Error: " + e.ToString() + "\n. Stack Trace: " + e.StackTrace;
}

回应是：

    <?xml version="1.0" encoding="utf-8"?>
    <Response xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://schemas.microsoft.com/search/local/ws/rest/v1">

    </Response>

该网址与在网络浏览器上工作的网址相同。有什么问题？

可能此时您已经想出了一个解决方案，但是在 google 上搜索我发现了这个主题，解决方案是不要像您那样通过 url 发送密钥，而是将其作为参数添加到请求中，如下所示：

string wsUrl = "http://dev.virtualearth.net/REST/v1/Locations/-30,-70/";    

var request = new RestSharp.RestRequest(Method.GET);    
request.AddParameter("includeEntityTypes", "AdminDivision1,CountryRegion");
request.AddParameter("key", myLey);
request.AddParameter("o", "xml");

如果我理解这一点，那么您使用的 REST API可能会花钱。也许您的 API 密钥没有为可计费交易设置？

该页面说明了 Location API 的计费：

*如果此类别发生在 AJAX 控件或 Silverlight 控件会话的上下文中，则不计费。

也许浏览器算作 AJAX 控件，而手机并不完全是“Silverlight 控件”。
