QT调用webService接口的代码?

答：要调用WebService接口，需要使用SOAP协议，并使用XML报文格式发送请求。 具体的代码实现，可以参考下面的示例： String soapEndpointUrl = "http://example.com/webservices/soap";
String soapAction = "http://example.com/webservices/soap/getData"; // Create SOAP Connection
SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
SOAPConnection soapConnection = soapConnectionFactory.createConnection(); // Send SOAP Message to SOAP Server
SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(soapAction), soapEndpointUrl); // print SOAP Response
System.out.print("Response SOAP Message:");
soapResponse.writeTo(System.out); // close SOAP connection
soapConnection.close();

QT webservice服务端 代码？

以下是一个简单的QT webservice服务端代码示例：

#include <QtCore/QCoreApplication>
#include <QtNetwork>
#include <QtXmlPatterns>

class MyWebService : public QObject
{
    Q_OBJECT
public:
    MyWebService(QObject *parent = 0) : QObject(parent)
    {
        //创建QTcpServer监听来自客户端的请求
        tcpServer = new QTcpServer(this);
        connect(tcpServer, SIGNAL(newConnection()), this, SLOT(onNewConnection()));
        if (!tcpServer->listen(QHostAddress::Any, 8080)) {
            qCritical() << "Failed to start server:" << tcpServer->errorString();
        } else {
            qDebug() << "Server started";
        }
    }

private slots:
    void onNewConnection()
    {
        //接收来自客户端的请求
        QTcpSocket *clientConnection = tcpServer->nextPendingConnection();
        connect(clientConnection, SIGNAL(disconnected()), clientConnection, SLOT(deleteLater()));
        connect(clientConnection, SIGNAL(readyRead()), this, SLOT(onReadyRead()));
    }

    void onReadyRead()
    {
        //读取客户端请求的数据
        QTcpSocket *clientConnection = qobject_cast<QTcpSocket *>(sender());
        if (!clientConnection) {
            return;
        }

        QByteArray requestData = clientConnection->readAll();
        qDebug() << "Received request:" << requestData;

        //构造响应并发送给客户端
        QByteArray responseData = "<response>Hello, world!</response>";
        clientConnection->write(responseData);
        clientConnection->disconnectFromHost();
    }

private:
    QTcpServer *tcpServer;
};

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    //创建WebService并启动
    MyWebService webService;
    return a.exec();
}

#include "main.moc"

这个示例代码创建了一个QTcpServer对象来监听来自客户端的请求，并在接收到请求时构造响应并发送回客户端。您可以根据您的需求修改响应的内容。

jdk17 调用webservice接口代码

你可以使用Java的JAX-WS库来调用WebService接口。以下是一个示例代码，演示了如何使用JDK17调用WebService接口：

import javax.xml.namespace.QName;
import javax.xml.ws.Service;
import java.net.URL;

public class WebServiceClient {
    public static void main(String[] args) throws Exception {
        // 创建访问URL
        URL url = new URL("http://example.com/your-service-url?wsdl");

        // 创建QName，指定命名空间和服务名称
        QName qname = new QName("http://example.com/your-service-namespace", "YourServiceName");

        // 创建Service实例
        Service service = Service.create(url, qname);

        // 获取服务实现类
        YourService serviceImpl = service.getPort(YourService.class);

        // 调用接口方法
        String result = serviceImpl.yourMethod(param1, param2);

        // 处理返回结果
        System.out.println("Result: " + result);
    }
}

请将上述代码中的`http://example.com/your-service-url?wsdl`替换为你要调用的WebService的URL，将`http://example.com/your-service-namespace`替换为相应的命名空间，将`YourServiceName`替换为服务名称。另外，还需根据WebService的定义修改`YourService`接口和相关方法。
