Windows phone 8 HTTP Post 请求

 

一般我们在写 http post 的时候 都是下边这种情况

1 HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);
2 
3 request.Method = "POST";
4 
5 request.ContentType = "application/x-www-form-urlencoded";
6 
7 request.ContentLength = Encoding.UTF8.GetByteCount(postDataStr);
8 
9 ...(省略代码,网上有很多就不多写了)

 1 private async Task<string> WebRequestPost(string uri, string requestDetails)
 2         {
 3             string result = string.Empty;
 4             WebRequest webRequest = WebRequest.Create(uri);
 5             webRequest.ContentType = "application/x-www-form-urlencoded";
 6             webRequest.Method = "POST";
 7             byte[] bytes = Encoding.UTF8.GetBytes(requestDetails);
 8             using (Stream outputStream = await webRequest.GetRequestStreamAsync())
 9             {
10                 outputStream.Write(bytes, 0, bytes.Length);
11             }
12             using (WebResponse webResponse = await webRequest.GetResponseAsync())
13             {
14                 StreamReader sr = new StreamReader(webResponse.GetResponseStream());
15                 result = sr.ReadToEnd();
16             }
17             return result;
18         }

14             {
15                 await stream.WriteAsync(buffer, 0, buffer.Length);
16             }
