C#调用Java的WebService添加SOAPHeader验证

C#调用Java的WebService添加SOAPHeader验证（2）

1.问题描述

调用的Java的webservice

string Invoke(string func, string reqXml)

　使用C#直接调用一直报错。

webservice提供方有说明如下：

身份验证采用对SOAP身份认证(用户名/密码验证/序列号)的方式部署，设定用户名和密码由系统配置，所有文本内容编码选择UTF-8编码规范
<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header>
<vc:Authentication xmlns: vc ="http://ant.com">
<vc:Username>[系统配置] </vc:Username>
<vc:Password>[系统配置]</vc:Password>
<vc:SerialNo>[系统配置]</vc:SerialNo >
</vc:Authentication>
</soapenv:Header>
<soapenv:Body>
</soapenv:Body>
</soapenv:Envelope> 

相信就是soapenv:Header这里的问题了，C# 没soapenv:Header这些东西的

网上查了好多类似下面的

C#访问Java的WebService添加SOAPHeader验证的问题

都没有用

后来尝试sopui及xmlspy创建soap，直接发送xml，终于试出来了，然后C#使用http post调用webservice，成功了。

2.问题解决1

C#拼接的需要http post的soap字符串如下

</SOAP-ENV:Header> 照搬给的文档里的字符串

<SOAP-ENV:Body> 为调用函数，string Invoke(string func, string reqXml) 函数名Invoke，两个参数，自行理解吧

注意：里面的
换行标志都要保留，不然都是报错

 string soap = "<?xml version="1.0" encoding="utf-8"?>
" +
                "<SOAP-ENV:Envelope
" +
                "xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
" +
                "xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
" +
                "xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
" +
                "xmlns:xsd="http://www.w3.org/2001/XMLSchema">
" +
                "<SOAP-ENV:Header>
" +
                    "<vc:Authentication
" +
                        "xmlns:vc="http://ant.com">
" +
                        "<vc:Username>xx</vc:Username>
" +
                        "<vc:Password>xxx</vc:Password>
" +
                        "<vc:SerialNo>xxxx</vc:SerialNo>
" +
                    "</vc:Authentication>
" +
                "</SOAP-ENV:Header>
" +
                "<SOAP-ENV:Body>
" +
                    "<m:Invoke
" +
                        "xmlns:m="http://tempuri.org/">
" +
                        "<m:func>" + jkid + "</m:func>
" +
                        "<m:reqXml>" + HttpUtility.HtmlEncode(xml) + "</m:reqXml>
" +
                    "</m:Invoke>
" +
                "</SOAP-ENV:Body>
" +
                "</SOAP-ENV:Envelope>";

　　然后发送，随便找个http post的代码就行了

 public static string GetSOAPReSource(string url, string datastr)
        {
            try
            {
                //request
                Uri uri = new Uri(url);
                WebRequest webRequest = WebRequest.Create(uri);
                webRequest.ContentType = "text/xml; charset=utf-8";

                webRequest.Method = "POST";
                using (Stream requestStream = webRequest.GetRequestStream())
                {
                    byte[] paramBytes = Encoding.UTF8.GetBytes(datastr.ToString());
                    requestStream.Write(paramBytes, 0, paramBytes.Length);
                }
                //response
                WebResponse webResponse = webRequest.GetResponse();
                using (StreamReader myStreamReader = new StreamReader(webResponse.GetResponseStream(), Encoding.UTF8))
                {
                    string result = "";
                    return result = myStreamReader.ReadToEnd();
                }
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }

　　

3.问题解决2

发现还是报错，http 500错误，和之前不一样，但依然不对

研究webservice的wsdl发现了问题

调用时加上

webRequest.Headers.Add("SOAPAction", "http://tempuri.org/IAjsjService/Invoke");

终于成功了

 public static string GetSOAPReSource(string url, string datastr)
        {
            try
            {
                //request
                Uri uri = new Uri(url);
                WebRequest webRequest = WebRequest.Create(uri);
                webRequest.ContentType = "text/xml; charset=utf-8";
                webRequest.Headers.Add("SOAPAction", "http://tempuri.org/IAjsjService/Invoke");

                webRequest.Method = "POST";
                using (Stream requestStream = webRequest.GetRequestStream())
                {
                    byte[] paramBytes = Encoding.UTF8.GetBytes(datastr.ToString());
                    requestStream.Write(paramBytes, 0, paramBytes.Length);
                }
                //response
                WebResponse webResponse = webRequest.GetResponse();
                using (StreamReader myStreamReader = new StreamReader(webResponse.GetResponseStream(), Encoding.UTF8))
                {
                    string result = "";
                    return result = myStreamReader.ReadToEnd();
                }
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }

　　

其他调用webservice的方式：

C# 调用WebService的3种方式 :直接调用、根据wsdl生成webservice的.cs文件及生成dll调用、动态调用
