WCF Rest不接受请求中的xml声明

我正在开发WCF REST服务,以接收来自第三方公司的输入。如果我发送一个简单的xml结构,它可以正常工作,但是如果请求中存在xml声明,则它会失败。不幸的是,我无法控制正在发送的内容,因此必须使用声明来完成此工作。

我的服务界面和实现如下:

[ServiceContract(Namespace = "")]
public interface IService1
{
    [OperationContract]
    [WebInvoke(Method = "POST",
        ResponseFormat = WebMessageFormat.Xml,
        RequestFormat = WebMessageFormat.Xml,
        BodyStyle = WebMessageBodyStyle.Bare,
    UriTemplate = "report")]
    ResponseData Report(testclass req);
}

public class Service : IService1
{
    public string Report(testclass req)
    {
        return req.operatorStatusMessage;
    }
}

这是我的测试班:

  [DataContract(Namespace = "", Name = "testclass")]
    public partial class testclass
    {
        [DataMember]
        public ushort id { get; set; }

        [DataMember]
        public byte statusCode { get; set; }

        [DataMember]
        public string statusMessage { get; set; }

        public testclass()
        { }
    }

..这是我的Web.config

 <system.serviceModel>
<services>
  <service name="SMSRep.Service" behaviorConfiguration="serviceBehavior">
    <endpoint address="" binding="webHttpBinding" contract="SMSRep.IService" behaviorConfiguration="webHttp" />
  </service>
</services>
<bindings>
  <webHttpBinding>
    <binding name="webHttpBinding" maxReceivedMessageSize="50000" />
  </webHttpBinding>
</bindings>
<behaviors>
  <serviceBehaviors>
    <behavior name="serviceBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="false"/>
    </behavior>
  </serviceBehaviors>
  <endpointBehaviors>
    <behavior name="webHttp">
      <webHttp />
    </behavior>
  </endpointBehaviors>
</behaviors>
<serviceHostingEnvironment aspNetCompatibilityEnabled="false" multipleSiteBindingsEnabled="true"/>

我要发送的xml是

<?xml version = "1.0" encoding="UTF8" ?>
<testclass>
   <id>6789</id>
   <statusCode>200</statusCode>
   <statusMessage>Some message</statusMessage>
 </testclass>

正如我提到的,如果没有xml声明,它就可以正常工作, 如果包含,则会收到错误“ 400错误请求”。 WebException的InnerException表示“协议错误”。

我发送的testapp看起来像这样:

const string url = "http://localhost:4337/Service.svc/Report";

    string txt = File.ReadAllText(xmlfile);
    byte[] requestBytes = Encoding.UTF8.GetBytes(txt);

    HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
    req.Method = "POST";
    req.ContentType = "text/xml;charset=utf-8";
    req.Timeout = 10000;
    req.ContentLength = requestBytes.Length;

    using (Stream streamWriter = req.GetRequestStream())
    {
        streamWriter.Write(requestBytes, 0, requestBytes.Length);
    }

    HttpWebResponse res = (HttpWebResponse)req.GetResponse();
    using (var streamReader = new StreamReader(res.GetResponseStream()))
    {
        var result = streamReader.ReadToEnd();
        txtReceive.Text = result;
    }

已经使用谷歌搜索了好几天,请给我一个提示!

xml 文件应该有架构实例。试试这样添加

<testclass xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\">
 <id>6789</id>
 <statusCode>200</statusCode>
 <statusMessage>Some message</statusMessage>
</testclass>

注意:删除根xml节点。

如果这也失败了。尝试使用 DataContractSerializer服务中的合同 进行数据合同序列化,然后检查 xml 字符串是否与您在请求中提供的内容相匹配。
