webservice客户端代码
以下是一个简单的QT Webservice客户端程序,实现了调用WSDL文件中的方法并传递参数,获取Webservice服务的响应结果。
```cpp
#include <QtCore/QCoreApplication>
#include <QtXml/QDomDocument>
#include <QtNetwork/QNetworkAccessManager>
#include <QtNetwork/QNetworkRequest>
#include <QtNetwork/QNetworkReply>
class WebserviceClient : public QObject
{
Q_OBJECT
public:
WebserviceClient(QObject *parent = 0) : QObject(parent)
{
manager = new QNetworkAccessManager(this);
}
void callWebService()
{
// Webservice URL
QString url = "http://localhost:8080/Webservice/Service";
// SOAP request XML
QString xmlRequest = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:ser=\"http://service.webservice.com/\"><soapenv:Header/><soapenv:Body><ser:method><arg0>parameter1</arg0><arg1>parameter2</arg1></ser:method></soapenv:Body></soapenv:Envelope>";
// Create request
QNetworkRequest request;
request.setUrl(QUrl(url));
request.setHeader(QNetworkRequest::ContentTypeHeader, "text/xml;charset=UTF-8");
request.setRawHeader("SOAPAction", "http://service.webservice.com/method");
// Send request
QNetworkReply *reply = manager->post(request, xmlRequest.toUtf8());
// Handle response
QObject::connect(reply, SIGNAL(finished()), this, SLOT(onWebServiceResponse()));
}
private slots:
void onWebServiceResponse()
{
QNetworkReply *reply = qobject_cast<QNetworkReply*>(sender());
if (reply->error() == QNetworkReply::NoError)
{
// Parse response XML
QDomDocument xmlResponse;
xmlResponse.setContent(reply->readAll());
// Extract response data
QString responseData = xmlResponse.documentElement().firstChild().firstChild().toElement().text();
// Output response data
qDebug() << responseData;
}
else
{
// Handle error
qDebug() << reply->errorString();
}
reply->deleteLater();
}
private:
QNetworkAccessManager *manager;
};
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
WebserviceClient client;
client.callWebService();
return a.exec();
}
```
在程序中,先定义了一个WebserviceClient类,用于封装Webservice客户端的相关功能。在类中,首先定义了一个QNetworkAccessManager对象,用于发送Webservice请求和接收Webservice响应。然后,实现了一个callWebService()方法,用于调用Webservice服务并传递参数。在方法中,首先定义了Webservice的URL和SOAP请求XML,然后创建了一个QNetworkRequest对象,并设置相关请求头部信息。接着,使用QNetworkAccessManager发送Webservice请求,并在onWebServiceResponse()槽函数中处理Webservice响应。在槽函数中,首先判断响应是否正常,如果正常则解析XML数据,提取响应数据并输出;如果出现错误则输出错误信息。最后,程序在main函数中创建了一个WebserviceClient对象,并调用了callWebService()方法来实现Webservice客户端的功能。
需要注意的是,Webservice服务的URL和SOAP请求XML需要根据具体情况进行调整。
