提取HTTP POST数据(WCF C#)

Question

如何在我的WCF服务中收到的HTTP POST请求中获取数据？

我使用HTTP POST从另一个服务发送数据:

        string ReportText = "Hello world";

        ASCIIEncoding encoding = new ASCIIEncoding();
        byte[] data = encoding.GetBytes(ReportText);

        // Prepare web request...
        String serverURL = ConfigurationManager.AppSettings["REPORT"];
        HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(serverURL);
        myRequest.Method = "POST";
        myRequest.ContentType = "application/x-www-form-urlencoded";
        myRequest.ContentLength = data.Length;
        Stream newStream = myRequest.GetRequestStream();

        // Send the data.
        newStream.Write(data, 0, data.Length);
        newStream.Close();

但是当我在WCF中收到POST请求时,我找不到使用WebOperationContext.Current.IncomingRequest提取它的方法,如何从HTTP POST请求中提取数据？

我的猜测是你正在使用WCF Rest服务,你可以提取GET参数,但是你无法读取RAW后期数据？

如果是这种情况,则将Stream参数添加到Contract声明中参数列表的末尾.如果函数末尾有单个流,则框架将其视为原始数据流.

          [OperationContract]
          [WebInvoke(Method = "POST", UriTemplate = "DoSomething?siteId={siteId}&configTarget={configTarget}", 
          RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
          bool DoSomething(string itemid, Stream body);


    public bool DoSomething(int siteId, string configTarget, Stream postData)
    {
        string data = new StreamReader(postData).ReadToEnd();
        return data.Length > 0;
    }
