我很难弄清楚为什么我在客户端的 POST 方法中收到了 400 个错误请求。我的其他 POST 方法适用于此服务和客户端。然而这个不工作？我希望一双新的眼睛可能会发现问题？
我的服务如下所示：
[OperationContract]
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Bare, RequestFormat = WebMessageFormat.Xml, ResponseFormat = WebMessageFormat.Xml, UriTemplate = "/Message")]
void AddMessage(Message message);
//Post Method for Message
[DataContract(Name = "Message")]
public class Message
{
[DataMember(Name = "MessageID")]
public string MessageID { get; set; }
[DataMember(Name = "GroupMessage")]
public string GroupMessage { get; set; }
//DataContracts for Message
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
public class RawDataService : IReceiveData
{
List<Message> messages = new List<Message>();
int eCount = 0;
public void AddMessage(Message message)
{
message.MessageID = (++eCount).ToString();
messages.Add(message);
}
// add message method, increment MessageID
要发布的客户端代码在标记行上给出 400 错误请求：
private void button15_Click(object sender, EventArgs e)
{
string uriMessage = "http://localhost:8000/Service/Message";
StringBuilder sb1 = new StringBuilder();
sb1.AppendLine("</Message>");
sb1.AppendLine("<GroupMessage>" + this.textBox22.Text + "</GroupMessage>");
sb1.AppendLine("</Message>");
string GroupMessage = sb1.ToString();
byte[] arr1 = Encoding.UTF8.GetBytes(GroupMessage);
HttpWebRequest req1 = (HttpWebRequest)WebRequest.Create(uriMessage);
req1.Method = "POST";
req1.ContentType = "application/xml";
req1.ContentLength = arr1.Length;
Stream reqStrm1 = req1.GetRequestStream();
reqStrm1.Write(arr1, 0, arr1.Length);
reqStrm1.Close();
HttpWebResponse resp1 = (HttpWebResponse)req1.GetResponse(); //400 bad request?
MessageBox.Show(resp1.StatusDescription);
reqStrm1.Close();
resp1.Close();
}
