C#怎么发送soap报文的请求

Iovswety 2013-05-21 01:39:51

我这边需要做一个平台，调度WebService请求以及监控服务的流量跟使用次数等这些操作，现在碰到个问题，用http协议post请求webService，怎么构造post的soap的报文呢？？

比如我某一个webService，soap 1.2请求格式是这样

POST /MyServices.asmx HTTP/1.1
Host: localhost
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://tempuri.org/HelloWorld"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<HelloWorld xmlns="http://tempuri.org/">
<abc>
<a>string</a>
<b>int</b>
<c>
<string>string</string>
<string>string</string>
</c>
</abc>
</HelloWorld>
</soap:Body>
</soap:Envelope>

我是这样写的，之后报了400错误，麻烦各位牛人帮帮忙看看。



string data = string.Format(@"

<?xml version=""1.0"" encoding=""utf-8""?>

<soap:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">

  <soap:Body>

    <HelloWorld xmlns=""http://tempuri.org/"">

      <abc>

        <a>纳菲恩</a>

        <b>123</b>

        <c>

          <string>gg</string>

          <string>ff</string>

          <string>火锅</string>

          <string>办法</string>

        </c>

      </abc>

    </HelloWorld>

  </soap:Body>

</soap:Envelope>");

 

            HttpWebRequest wrt = (HttpWebRequest)WebRequest.Create("http://localhost:9542/MyServices.asmx");

            wrt.Headers.Add("Accept-Encoding", "gzip,deflate,sdch");

            wrt.Headers.Add("Accept-Language", "zh-CN,zh;q=0.8");

            wrt.Headers.Add("Cache-Control", "max-age=0");

            wrt.Headers.Add("SOAPAction", "http://tempuri.org/HelloWorld");

            wrt.ContentType = "text/xml; charset=utf-8";

            wrt.Method = "POST";

            wrt.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.172 Safari/537.22";

            wrt.Referer = "http://localhost:9542/MyServices.asmx?op=HelloWorld";

            wrt.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";

            wrt.Connection = "Open";

 

            byte[] byteArray = Encoding.UTF8.GetBytes(data);

            wrt.ContentLength = byteArray.Length;

            Stream stream = wrt.GetRequestStream();

            stream.Write(byteArray, 0, byteArray.Length);

            stream.Close();

            string html = ReadZipData(wrt);
