await Request
由于WP上对HTTP的请求都采用异步的方式，以下代码可以把它变成同步可等待的方式
public static string GetContentFromURL(string url)
{
var task = GetResult(url);
return task.Result;
}
private static Task<string> GetResult(string url)
{
url = url.Replace("http://","");
url = "http://" + url;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "GET";
request.UserAgent = "Mozilla/5.0 (Linux; U; Android 4.0.3; de-ch; HTC Sensation Build/IML74K) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30";
Task<WebResponse> task = Task.Factory.FromAsync(
request.BeginGetResponse, asyncResult => request.EndGetResponse(asyncResult), (object)null
);
return task.ContinueWith(t => ReadStreamFromResponse(t.Result));
}
private static string ReadStreamFromResponse(WebResponse response)
{
using (Stream responseStream = response.GetResponseStream())
using (StreamReader sr = new StreamReader(responseStream))
{
//Need to return this response
string strContent = sr.ReadToEnd();
return strContent;
}
}
