C#調用Java的WebService添加SOAPHeader驗證（2）html

1.問題描述web

調用的Java的webservice函數

string Invoke(string func, string reqXml)post

　使用C#直接調用一直報錯。ui

webservice提供方有說明以下：編碼

身份驗證採用對SOAP身份認證(用戶名/密碼驗證/序列號)的方式部署，設定用戶名和密碼由系統配置，全部文本內容編碼選擇UTF-8編碼規範
<?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>[系統配置] </vc:Username>
<vc:Password>[系統配置]</vc:Password>
<vc:SerialNo>[系統配置]</vc:SerialNo >
</vc:Authentication>
</soapenv:Header>
<soapenv:Body>
</soapenv:Body>
</soapenv:Envelope>

相信就是soapenv:Header這裏的問題了，C# 沒soapenv:Header這些東西的url

網上查了好多相似下面的spa

C#訪問Java的WebService添加SOAPHeader驗證的問題

都沒有用xml

後來嘗試sopui及xmlspy建立soap，直接發送xml，終於試出來了，而後C#使用http post調用webservice，成功了。

2.問題解決1

C#拼接的須要http post的soap字符串以下

</SOAP-ENV:Header> 照搬給的文檔裏的字符串

<SOAP-ENV:Body> 爲調用函數，string Invoke(string func, string reqXml) 函數名Invoke，兩個參數，自行理解吧

注意：裏面的\r\n換行標誌都要保留，否則都是報錯

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

　　而後發送，隨便找個http post的代碼就好了

 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.問題解決2

發現仍是報錯，http 500錯誤，和以前不同，但依然不對

研究webservice的wsdl發現了問題

調用時加上

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

終於成功了

 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;
            }
        }

其餘調用webservice的方式：
