我是使用下面的代码通过HttpWebRequest使用此Web服务和

得到错误远程服务器返回错误：（400）错误请求。它适用于get方法.----

I am using below code to use this web service through HttpWebRequest and
got error "The remote server returned an error: (400) Bad Request." It working fine for get method.----

string postData = string.Format("user={0}&pwd={1}", "me", "123");
            HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("http://localhost:52631/Service1.svc/chkUserPwd");
            webRequest.Method = "POST";
            webRequest.ContentType = "application/x-www-form-urlencoded";
            webRequest.ContentLength = postData.Length;
            try
            {
                using (StreamWriter requestWriter2 = new StreamWriter(webRequest.GetRequestStream()))
                {
                    requestWriter2.Write(postData);
                }

                using (StreamReader responseReader = new StreamReader(webRequest.GetResponse().GetResponseStream()))
                {
                    // dumps the HTML from the response into a string variable
                    postData = responseReader.ReadToEnd();
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
            }

推荐答案

credential obj = new credential();
            obj.user = "me";
            obj.pwd = "123";
            JavaScriptSerializer js = new JavaScriptSerializer();
            string postData= js.Serialize(obj);
            HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("http://localhost:52631/Service1.svc/chkUserPwd");
            webRequest.Method = "POST";
            webRequest.ContentType = "application/json"
            webRequest.ContentLength = postData.Length;
            try
            {
                using (StreamWriter requestWriter2 = new StreamWriter(webRequest.GetRequestStream()))
                {
                    requestWriter2.Write(postData);
                }

                using (StreamReader responseReader = new StreamReader(webRequest.GetResponse().GetResponseStream()))
                {
                    // dumps the HTML from the response into a string variable
                    postData = responseReader.ReadToEnd();
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
            }

public class credential
        {
            public string user { get; set; }
            public string pwd { get; set; }
        }

正如我在WebInvoke上提到的那样是BodyStyle = WebMessageBodyStyle.Wrapped然后我们必须发布数据json或xml。

As I mentioned on WebInvoke is BodyStyle = WebMessageBodyStyle.Wrapped then we must post the data json or xml.
