在C＃中添加一个肥皂头

Question

我正在为Android构建Xamarin.forms应用程序，我们在其中使用第三方Web服务。 我已经创建了代理，并且可以看到该服务公开的方法。

但是我无法访问服务的方法，因为必须将标头添加到使用密钥的SOAP请求中。

代码段：为代理创建客户端

ThirdPartAuthService.AuthService clnt = new ThirdPartAuthService.AuthService();
clnt.getenquiry(XML);

我看不到添加标头以便进行身份验证的任何选项。 请指导我如何向我的请求添加肥皂标头。

在Android应用程序中可能会发生这种情况，因为他们正在创建添加标头并发送的SOAP对象。

样本标头xml请求：

<?xml version="1.0" encoding="utf-8"?>...
    <soapenv:Header><ns1:encKey soapenv:actor="http://schemas.xmlsoap.org/
    soap/actor/next"  xsi:type="soapenc:string" xmlns:ns1=
     xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">
    abcde</ns1:encKey></soapenv:Header>..

我需要添加令牌，用户名和密码

基本上你不能。 您必须手动更改Soap文本，例如：

 String soapBodyString = getXMLFromCache ();

                int pos1 = soapBodyString.IndexOf ("<soap:Body");  
                int pos2 = soapBodyString.Length - pos1;

                soapBodyString = soapBodyString.Substring (pos1, pos2);

                string headerText = "<?xml version=\"1.0\" encoding=\"utf-8\"?>"
                    + "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" \n{0}>"
                    + "<soapenv:Header><wsse:Security xmlns:wsse=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd\">"
                    + "<wsse:UsernameToken xmlns:wsu=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\">"
                    + "<wsse:Username>{1}</wsse:Username>"
                    + "<wsse:Password>{2}</wsse:Password>"
                    + "<wsse:Signature>{3}</wsse:Signature>"
                    + "</wsse:UsernameToken></wsse:Security></soapenv:Header>";


                Stream appOutputStream = new MemoryStream ();
                StreamWriter soapMessageWriter = new StreamWriter (appOutputStream);

                    headerText = string.Format (headerText,UriNamespace ,Username, Password, Signature);
                soapMessageWriter.Write (headerText);
                soapBodyString=soapBodyString.Replace("soap:Envelope", "soapenv:Envelope");
                soapBodyString=soapBodyString.Replace("soap:Body", "soapenv:Body");
                soapMessageWriter.Write(soapBodyString);

                soapMessageWriter.Flush();
                appOutputStream.Flush();
                appOutputStream.Position = 0;

                StreamReader reader = new StreamReader(appOutputStream);
                StreamWriter writer = new StreamWriter(this.outputStream);
                writer.Write(reader.ReadToEnd());
                writer.Flush();
                appOutputStream.Close();

通过覆盖reference.cs中的System.Net.WebRequest修复了此问题

protected override System.Net.WebRequest GetWebRequest(Uri uri)
    { 

        HttpWebRequest request;
        request = (HttpWebRequest)base.GetWebRequest(uri);
        NetworkCredential networkCredentials =   Credentials.GetCredential(uri, "Basic");

        //Other credentials  

        return request;

    }
