在 C# 中添加肥皂 header

Question

我正在为 android 构建一个 Xamarin.forms 应用程序，我们在其中使用第三方网络服务。我已经创建了代理，我可以看到服务公开的方法。

但是我无法访问该服务的方法，因为我必须将 header 添加到我的获取密钥的 SOAP 请求中。

代码片段：为代理创建客户端

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

我没有看到任何添加 header 的选项，以便进行身份验证。请指导我如何在我的请求中添加肥皂 header..

它可能在 android 应用程序中创建 SOAP object 附加 header 并发送。

示例 header 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();

Answer 2

通过覆盖 reference.cs

中的 System.Net.WebRequest 修复了它

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;

    }
