SOAP对象通过HTTP后在C＃.NET

Question

我想在C＃.NET撰写的SOAP消息（包括标题）以发送到使用HTTP后的URL。我想将它发送到URL不是Web服务，它只是接收SOAP消息，最终从中提取信息。如何做到这一点任何想法？

首先，你需要创建一个有效的XML。我使用LINQ XML来实现这一点，像如下：

XNamespace soapenv = "http://schemas.xmlsoap.org/soap/envelope/";
var document = new XDocument(
               new XDeclaration("1.0", "utf-8", String.Empty),
               new XElement(soapenv + "Envelope",
                   new XAttribute(XNamespace.Xmlns + "soapenv", soapenv),
                   new XElement(soapenv + "Header",
                       new XElement(soapenv + "AnyOptionalHeader",
                           new XAttribute("AnyOptionalAttribute", "false"),
                       )
                   ),
                   new XElement(soapenv + "Body",
                       new XElement(soapenv + "MyMethodName",
                            new XAttribute("AnyAttributeOrElement", "Whatever")
                       )
                   )
                );

然后，我使用它发送（修改的：加入XDocument.ToString()向下这里）

            var req = WebRequest.Create(uri);
            req.Timeout = 300000;  //timeout
            req.Method = "POST";
            req.ContentType = "text/xml;charset=UTF-8";

            using (var writer = new StreamWriter(req.GetRequestStream()))
            {
                writer.WriteLine(document.ToString());
                writer.Close();
            }

如果我要读一些响应，我（这随动上面的代码的）：

            using (var rsp = req.GetResponse())
            {
                req.GetRequestStream().Close();
                if (rsp != null)
                {
                    using (var answerReader = 
                                new StreamReader(rsp.GetResponseStream()))
                    {
                        var readString = answerReader.ReadToEnd();
                        //do whatever you want with it
                    }
                }
            }

你的代码上面缺少一个括号，并有一个额外的逗号，我固定在这里：

XNamespace soapenv = "http://schemas.xmlsoap.org/soap/envelope/"; 
var document = new XDocument( 
    new XDeclaration("1.0", "utf-8", String.Empty), 
    new XElement(soapenv + "Envelope", 
        new XAttribute(XNamespace.Xmlns + "soapenv", soapenv), 
        new XElement(soapenv + "Header", 
            new XElement(soapenv + "AnyOptionalHeader", 
                new XAttribute("AnyOptionalAttribute", "false")
            ) 
        ), 
        new XElement(soapenv + "Body", 
            new XElement(soapenv + "MyMethodName", 
                new XAttribute("AnyAttributeOrElement", "Whatever") 
            ) 
        ) 
    )
);
