如何在 Java（或 C#）中使用摘要身份验证 HTTP 通过 HTTP 发送 SOAP 请求？

Question

我的网络服务 url 是 http://192.168.0.10/services/abc?wsdl
此 Web 服务器使用摘要身份验证，用户名是 admin，密码是 admin
我想将请求发送到此服务器

SOAP 请求 XML 是 SOAP_RQ.XML

 <soapenv:Envelope
    xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:log="LogsGet" xmlns:mal="MalteseGlobal" xmlns:job="JobGlobal">
         <soapenv:Body>
             <log:LogsGetReq Cmd="Start" OpV="01.00.00" Sev="Info to critical"/>
          </soapenv:Body>
</soapenv:Envelope>

我的代码：

 private static SOAPMessage createSOAPRequest(String username, String password) throws Exception {
        MessageFactory messageFactory = MessageFactory.newInstance();
        SOAPMessage soapMessage = messageFactory.createMessage();
        SOAPPart soapPart = soapMessage.getSOAPPart();
        // SOAP Envelope
        SOAPEnvelope envelope = soapPart.getEnvelope();
        envelope.addNamespaceDeclaration("log", "LogsGet");
        envelope.addNamespaceDeclaration("mal", "MalteseGlobal");
        envelope.addNamespaceDeclaration("job", "JobGlobal");
        // SOAP Body
        SOAPBody soapBody = envelope.getBody();
        SOAPElement soapBodyElem = soapBody.addChildElement("LogsGetReq", "log");
        QName Cmd = new QName("Cmd");
        QName OpV = new QName("OpV");
        QName Sev = new QName("Sev");
        soapBodyElem.addAttribute(Cmd, "Start");
        soapBodyElem.addAttribute(OpV, "01.00.00");
        soapBodyElem.addAttribute(Sev, "Info to critical");
        //SOAP Header
        MimeHeaders hd = soapMessage.getMimeHeaders();
        hd.addHeader("UsernameToken", username);
        hd.addHeader("PasswordText", password);

        soapMessage.saveChanges();       
        return soapMessage;
    }

public void sendSoapRequest(String url, String username, String password) {
        try {
            // Create SOAP Connection
            SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
            SOAPConnection soapConnection = soapConnectionFactory.createConnection();

            // Send SOAP Message to SOAP Server         
            SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(username, password, txtArea), url);
            // Process the SOAP Response               
            ByteArrayOutputStream bos = new ByteArrayOutputStream();
            soapResponse.writeTo(bos);
            System.out.println();  
            soapConnection.close();

        } catch (Exception e) {
            System.out.println("Error occurred while sending SOAP Request to Server");              
            e.printStackTrace();
        }
    }

当我发送请求时，我收到了如下消息：错误响应：（需要 401 授权）

如果我发送请求使用 curl 工具 (http://curl.haxx.se/download/curl-7.41.0.zip) 命令行：curl.exe -X POST http://192.168.0.10/services/Maltese -H "Content-Type: text/xml; charset=utf-8" -H "SOAPAction:LogsGet" --digest -u admin:admin -d @SOAP_RQ.xml-v
我收到消息回复OK。

任何人都可以帮助我，如何使用 JAVA（或 C#）通过 HTTP 发送 SOAP 请求？

谢谢

如果使用 C#
