使用PostAsync将XML传输到自托管WCF服务

假设我使用BasicHttpsBinding提供了以下WCF服务：

[ServiceContract]
    public interface IHelloWorld
    {
        [OperationContract]
        void HelloWorld();
    }

我必须如何更改它才能处理以下包含XML数据的PostAsync请求

httpContent = new StringContent(xmlDoc.ToString(), Encoding.UTF8, "application/xml");
httpClient.PostAsync(requestURI, httpContent);

还是有更好的方法

谢谢大家!

约翰，这是我的解决办法。我必须面对几个问题：选择哪个绑定（WebHttpBinding）、处理PostAsync（同步方法中的异步）以及防止StringWriter将UTF8更改为UTF16

在服务器端，界面如下所示：

[ServiceContract]
[XmlSerializerFormat]
public interface IHelloWorld
{
    [OperationContract]
    [WebInvoke(Method = "POST",
               RequestFormat = WebMessageFormat.Xml,
               BodyStyle = WebMessageBodyStyle.Bare,
               UriTemplate = "")]
    void HelloWorld(MyRequest request);
}

var _serializer = new XmlSerializer(typeof(MyRequest));
StringContent _httpContent;

// We need to keep UTF8 encoding here (StringWriter uses UTF16 by default)
using (StringWriter _textWriter = new Utf8StringWriter())
{
     _serializer.Serialize(_textWriter, _ebicsRequest);
     _httpContent = new StringContent(_textWriter.ToString(), Encoding.UTF8, "application/xml");
}

HttpClient _httpClient = new HttpClient();
var task = _httpClient.PostAsync(_requestURI, _httpContent).Result;

属性XmlSerializerFormat指示WCF应该使用XMLSerializer而不是默认的DataContractSerializer。为了使其正常工作，必须使用[XmlElement]、[XmlAttribute]等对类MyRequest进行正确注释，请参阅

这是我配置WCF主机的地方：

WebServiceHost host = new WebServiceHost(typeof(HelloWorldService));

WebHttpBinding binding = new WebHttpBinding();
binding.Security.Mode = WebHttpSecurityMode.Transport;

var endpoint = host.AddServiceEndpoint(typeof(IHelloWorld), binding, _address);
endpoint.Behaviors.Add(new WebHttpBehavior());

host.Open();            

在客户端，代码如下所示：

[ServiceContract]
[XmlSerializerFormat]
public interface IHelloWorld
{
    [OperationContract]
    [WebInvoke(Method = "POST",
               RequestFormat = WebMessageFormat.Xml,
               BodyStyle = WebMessageBodyStyle.Bare,
               UriTemplate = "")]
    void HelloWorld(MyRequest request);
}

var _serializer = new XmlSerializer(typeof(MyRequest));
StringContent _httpContent;

// We need to keep UTF8 encoding here (StringWriter uses UTF16 by default)
using (StringWriter _textWriter = new Utf8StringWriter())
{
     _serializer.Serialize(_textWriter, _ebicsRequest);
     _httpContent = new StringContent(_textWriter.ToString(), Encoding.UTF8, "application/xml");
}

HttpClient _httpClient = new HttpClient();
var task = _httpClient.PostAsync(_requestURI, _httpContent).Result;

我在这里找到了Utf8StringWriter类：。

我需要使用SOAP而不是XML吗？我试图在中重现答案，但到目前为止运气不佳。此外，我已根据此链接使用HTTPS配置了WCF服务
