将XML发送到WCF时出现400错误请求

我正在尝试将一些XML发布到Web服务,每次我都会收到400 Bad Request错误。

在MyService.cs中:

[ServiceContract(Namespace = "http://foo")]
public class MyService
{

    [OperationContract, WebInvoke(UriTemplate = "/GetData/", RequestFormat = WebMessageFormat.Xml, ResponseFormat = WebMessageFormat.Xml, BodyStyle = WebMessageBodyStyle.Bare, Method = "POST")]
    public string GetData(DataRequest req)
    {
        return "Success!";
    }
}

[DataContract(Namespace = "http://foo")]
public class DataRequest
{
    [DataMember]
    public string ID { get; set; }
    [DataMember]
    public string Data { get; set; }
}

在单独的控制台应用程序Program.cs中:

    Path p = "C:\\Users\\sflan\\Desktop\\test.xml";
    string url = "http://foo/MyService.svc/GetData/";
    HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
    req.Method = "POST";
    req.ContentType = "application/xml";

    byte[] data = Encoding.UTF8.GetBytes(p.readFile());
    req.ContentLength = data.Length;
    using (Stream s = req.GetRequestStream())
    {
        s.Write(data, 0, data.Length);
        s.Close();
    }

    try
    {
        WebResponse response = req.GetResponse();
        using (StreamReader rdr = new StreamReader(response.GetResponseStream()))
        {
            Console.WriteLine(rdr.ReadToEnd());
            rdr.Close();
        }
    }
    catch (Exception ex) { Console.WriteLine(ex.Message); }

我试图在文件中发送的XML:

<root>
    <Users ID="2" Data="This is some sample data." />
</root>

我搜索了几个小时寻找解决方案,但一直找不到。我的web.config允许最大缓冲区大小/ poolsize和我能找到的所有相关内容,但仍然没有运气。值得注意的是,如果我从GetData方法签名中删除“DataRequest req”,我会得到我的成功消息,但我需要能够使用XML数据。

谁能告诉我我做错了什么?

答案 0 :(得分:1)

XML的格式很差,我不会从以同一问题为中心的帖子中找到答案。

适当的XML如下:

 <DataRequest xmlns="http://foo">
      <Data>This is some sample data.</Data>
      <ID>2</ID>
 </DataRequest>
