在 System.Net 命名空间下提供了 HttpWebRequest 与 HttpWebResponse 类。....本系列文章详细介绍了 HttpWebRequest 与 HttpWebResponse 类以及其重要的属性、方法，最后提供了封装好的通用方法。
HttpWebResponse.StatusCode 属性获取响应的状态。对应 HttpStatusCode 枚举值之一。...示例 下面的示例将返回的状态进行比较HttpWebResponse的成员HttpStatusCode类来确定响应的状态。...HttpWebRequest)WebRequest.Create("http://www.contoso.com"); 2 httpReq.AllowAutoRedirect = false; 3 4 HttpWebResponse...httpRes = (HttpWebResponse)httpReq.GetResponse(); 5 6 if (httpRes.StatusCode==HttpStatusCode.Moved...包含的 HTTP 请求的状态 HttpWebResponse.StatusCode 属性。
httpWebResponse = httpWebRequest.GetResponse() as HttpWebResponse; // 获取响应 10 if (httpWebResponse...httpWebResponse = httpWebRequest.GetResponse() as HttpWebResponse; // 获取响应 20 if (httpWebResponse...httpWebResponse = httpWebRequest.GetResponse() as HttpWebResponse; // 获取响应 17 if (httpWebResponse...httpWebResponse = httpWebRequest.GetResponse() as HttpWebResponse; // 获取响应 if (httpWebResponse !...httpWebResponse = httpWebRequest.GetResponse() as HttpWebResponse; 21 if (httpWebResponse !
例子 下面的示例返回一个从HttpWebRequest 对象返回的 HttpWebResponse对象。...httpWResp = httpWReq.GetResponse() as HttpWebResponse; 4 if(httpWResp!...该HttpWebResponse类用于构建发送HTTP请求HTTP独立的客户端应用程序和接收HTTP响应。...您必须调用Stream.Close或HttpWebResponse.Close方法来关闭响应并释放连接以便重用。...下表显示了可通过属性的常见 HTTP 标头HttpWebResponse类。
string PostRequest(string Url, string Param) { HttpWebRequest request; HttpWebResponse...request.GetRequestStream().Write(Data, 0, Data.Length); response = (HttpWebResponse...(WebException ex) { strValue = ex.Message; response = (HttpWebResponse...request.ContentType = "application/json;charset=UTF-8"; response = (HttpWebResponse...(WebException ex) { strValue = ex.Message; response = (HttpWebResponse
httpWebResponse = httpWebRequest.GetResponse() as HttpWebResponse; 37 if (httpWebResponse !...= null) 38 { 39 GetResponse(ref httpResult, httpWebResponse); 40 httpWebResponse.Close...">正在被读取的HTTP响应 6 private void GetResponse(ref HttpResult httpResult, HttpWebResponse httpWebResponse...) 7 { 8 httpResult.HttpWebResponse = httpWebResponse; 9 httpResult.Status = HttpResult.STATUS_SUCCESS...exResponse = webException.Response as HttpWebResponse; 9 if (exResponse !
httpWebResponse = null; if (File.Exists(savepath)) { File.Delete...= null) { httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse...= null) { httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse...= null) { httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse...= null) { httpWebResponse = (HttpWebResponse)await httpWebRequest.GetResponseAsync
httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse(); //利用Stream流读取返回数据 StreamReader...streamReader = new StreamReader(httpWebResponse.GetResponseStream(), Encoding.UTF8); //获得最终数据，一般是json...string responseContent = streamReader.ReadToEnd(); streamReader.Close(); httpWebResponse.Close...httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse(); //读取返回数据 StreamReader streamReader...(); streamReader.Close(); httpWebResponse.Close(); httpWebRequest.Abort(); return responseContent
data.Length); 26 requestStream.Flush(); 27 } 28 } 29 30 HttpWebResponse...httpWebResponse = httpWebRequest.GetResponse() as HttpWebResponse; 31 if (httpWebResponse !...= null) 32 { 33 GetResponse(ref httpResult, httpWebResponse); 34 httpWebResponse.Close
通过http进行post请求获得json数据，并将HttpWebResponse返回结果转换为string /// /// 向指定URL发送HTTP请求...writer.Write(jsonBody); writer.Flush(); } stream.Close(); HttpWebResponse...response = null; string json = string.Empty; response = (HttpWebResponse)request.GetResponse...getResponseString(response); return json; } /// /// 将 HttpWebResponse... /// 服务器返回数据JSON private static string getResponseString(HttpWebResponse
此方法会返回一个 HttpWebResponse 对象，该对象包含了响应的详细信息。...csharp复制代码HttpWebResponse response = (HttpWebResponse)request.GetResponse();4....读取响应内容获取到 HttpWebResponse 对象后，可以通过其 GetResponseStream() 方法获取响应的数据流，然后使用 StreamReader 来读取流中的数据。...response = (HttpWebResponse)request.GetResponse()) using (Stream responseStream = response.GetResponseStream...response = (HttpWebResponse)request.GetResponse()) using (Stream responseStream = response.GetResponseStream
HttpWebRequest 请求时，服务器会返回500 501这些错误 并包含错误信息，通过如下代码可以拿到错误信息 HttpWebResponse res; try { res =...(HttpWebResponse)req.GetResponse(); } catch (WebException ex) { res = (HttpWebResponse)ex.Response
data.Length); 33 requestStream.Flush(); 34 } 35 } 36 37 HttpWebResponse...httpWebResponse = httpWebRequest.GetResponse() as HttpWebResponse; 38 if (httpWebResponse !...= null) 39 { 40 GetResponse(ref httpResult, httpWebResponse); 41 httpWebResponse.Close...httpWebResponse = httpWebRequest.GetResponse() as HttpWebResponse; 39 if (httpWebResponse !...= null) 40 { 41 GetResponse(ref httpResult, httpWebResponse); 42 httpWebResponse.Close
//500 error but get the message HttpWebResponse res; try {...res = (HttpWebResponse)webRequest.GetResponse(); } catch (WebException ex)...{ res = (HttpWebResponse)ex.Response; } StreamReader sr = new
string PostRequest(string Url, string Param) { HttpWebRequest request; HttpWebResponse...request.GetRequestStream().Write(Data, 0, Data.Length); response = (HttpWebResponse...(WebException ex) { strValue = ex.Message; response = (HttpWebResponse...request.GetRequestStream().Write(Data, 0, Data.Length); response = (HttpWebResponse...(WebException ex) { strValue = ex.Message; response = (HttpWebResponse

HttpWebRequest和HttpWebResponse类是用于发送和接收HTTP数据的最好选择。它们支持一系列有用的属性。...接下来调用 HttpWebRequest.GetResponse()方法返回的是一个HttpWebResponse对象。...response = (HttpWebResponse)request.GetResponse()) { if (cookieContainer !...httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse(); StreamReader streamReader =...httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse(); StreamReader streamReader =
sbKV.Length - 1); 36 requestStream.Flush(); 37 } 38 } 39 40 HttpWebResponse...httpWebResponse = httpWebRequest.GetResponse() as HttpWebResponse; 41 if (httpWebResponse !...= null) 42 { 43 GetResponse(ref httpResult, httpWebResponse); 44 httpWebResponse.Close
newStream.Write(data, 0, data.Length); newStream.Close(); HttpWebResponse...myResponse = (HttpWebResponse)myRequest.GetResponse(); StreamReader reader = new StreamReader...newStream.Write(data, 0, data.Length); newStream.Close(); HttpWebResponse...myResponse = (HttpWebResponse)myRequest.GetResponse(); StreamReader reader = new StreamReader
4、本例子使用的技术为 HttpWebRequest类、HttpWebResponse类及Newtonsoft.Json.JsonConvert类的使用，自己有不懂的，请自行进行百度； 5、源代码如下：...WebRequest.CreateHttp(@"http://www.nmc.gov.cn/f/rest/province"); try { HttpWebResponse...response = request.GetResponse() as HttpWebResponse; Stream stream = response.GetResponseStream...www.nmc.gov.cn/f/rest/province/{proviceNamedict[provice]}"); response = request.GetResponse() as HttpWebResponse...www.nmc.gov.cn/f/rest/real/{cityNamedict[city]}"); response = request.GetResponse() as HttpWebResponse
