我使用以下代码:
var request = (HttpWebRequest)WebRequest.Create(new Uri(addy));
request.UserAgent = "Mozilla/5.0 (Windows; U; MSIE 9.0; WIndows NT 9.0; en-US))";
request.BeginGetResponse(
r =>
{
var httpRequest = (HttpWebRequest)r.AsyncState;
var httpResponse = (HttpWebResponse)httpRequest.EndGetResponse(r);
using (var reader = new StreamReader(httpResponse.GetResponseStream()))
{
var response = reader.ReadToEnd();
results = (String)response;
}
}, request);
addy是:http://maps.googleapis.com/maps/api/geocode/xml?address=limavady&sensor=false
,结果只是一个全局字符串,我想输出Web请求的结果。
问题只是我一直得到结果的空值输出,我检查了网址,它是正确的,应该有输出。
关于这一点的任何想法,或者如果你能指出我正确的方向,我将不胜感激

Content-Encoding: gzip
向您发送数据。将NuGet包SharpZipLib.WindowsPhone7
添加到您的项目中,并查看下面的示例代码。检查HttpWebResponse.StatusCode
属性。
static Stream responseStream( this HttpWebResponse resp )
{
if( null == resp ) return null;
string enc = resp.Headers[ HttpRequestHeader.ContentEncoding ];
if( !string.IsNullOrEmpty( enc ) )
{
enc = enc.ToLower();
if( enc == "gzip" )
return new GZipInputStream( resp.GetResponseStream() );
}
return resp.GetResponseStream();
}

感谢您的帮助,我设法使用以下方法解决了问题:
WebClient webClient = new WebClient();
webClient.OpenReadAsync(new Uri(addy));
webClient.OpenReadCompleted += new OpenReadCompletedEventHandler(webClient_OpenReadCompleted);
}
void webClient_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e)
{
var reader = new StreamReader(e.Result);
results = reader.ReadToEnd();
}
