Qt 访问 webservice 服务

一，利用QtSoap 第三方库方式

参考：GitHub - commontk/QtSOAP: The Qt SOAP project provides basic web service support with version 1.1 of the SOAP protocol. It is fork of

二，利用 http post方式，自己拼接xml

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:v1="http://portal.vidyo.com/user/v1_1">
<soapenv:Header/>
<soapenv:Body>
<v1:SearchRequest>
<v1:Filter>
<v1:query>liunianji</v1:query>
</v1:Filter>
</v1:SearchRequest>
</soapenv:Body>
</soapenv:Envelope>

在一些复杂的xml格式下，如上述格式 <v1:query> 上层有好多父节点，利用第一种没有搞定所以选择了第二种方式

（1），拼接 xml

QDomDocument doc;QDomElement tagStart = doc.createElement("soapenv:Envelope");tagStart.setAttribute("xmlns:soapenv","http://schemas.xmlsoap.org/soap/envelope/");tagStart.setAttribute("xmlns:v1","http://portal.vidyo.com/user/v1_1");QDomElement tagHeader = doc.createElement("soapenv:Header");QDomElement tagBody = doc.createElement("soapenv:Body");doc.appendChild(tagStart);tagStart.appendChild(tagHeader);tagStart.appendChild(tagBody);QDomElement tagSearchRequest = doc.createElement("v1:SearchRequest");QDomElement tagFilter = doc.createElement("v1:Filter");QDomElement tagQuery = doc.createElement("v1:query");QDomText queryName = doc.createTextNode(displayName);tagBody.appendChild(tagSearchRequest);tagSearchRequest.appendChild(tagFilter);tagFilter.appendChild(tagQuery);tagQuery.appendChild(queryName);

（2），post 发送

QString webSite = QString("%1/services/v1_1/VidyoPortalUserService/").arg(m_portal);QByteArray postBa = doc.toByteArray();QByteArray retBa;QNetworkReply::NetworkError ret=WebHelp::getInstance()->sendPostRequest(webSite,postBa,retBa);if(ret==QNetworkReply::NoError){qDebug()<< QString(retBa);return parseSearchClassRe(retBa);}else{qDebug()<< QStringLiteral("网络错误，请检查网络！")<<ret;}

三，封装好的单例类

class   WebHelp:public QObject
{Q_OBJECT
private:class Dispose{public:~Dispose();};
public:static WebHelp * getInstance();~WebHelp();public:QNetworkReply::NetworkError sendGetRequest(QString urlStr, QByteArray & ba, int timeOutms=3000);QNetworkReply::NetworkError sendPostRequest(QString website,const QByteArray & postBa, QByteArray& retBa, int timeOutms=3000);protected slots:void slot_error(QNetworkReply::NetworkError code);void provideAuthenication(QNetworkReply*,QAuthenticator*);
private:static WebHelp * serverHelp;static WebHelp::Dispose disp;QNetworkAccessManager *manager;QNetworkReply::NetworkError m_errCode;QString m_pwd;QString m_user;
private:WebHelp(QObject *parent=0);};class NetDataListenerThread:public QThread
{Q_OBJECT
public:NetDataListenerThread(QNetworkAccessManager *manager,QNetworkReply * reply,int timeoutms,QObject *parent = 0);~NetDataListenerThread();QByteArray getBa() const;bool getIsWaitTimeOut() const;protected:virtual void run();
private:bool waitForConnect();
protected slots:void slot_waitTimeout();signals:void sig_waitTimeout();
private:QNetworkAccessManager *mManager;int m_TimeOutms;bool m_waitTimeOut;bool m_isWaitTimeOut;QNetworkReply * m_reply;
};

NetDataListenerThread::NetDataListenerThread(QNetworkAccessManager *manager, QNetworkReply *reply, int timeoutms, QObject *parent):QThread(parent),mManager(manager),m_TimeOutms(timeoutms),m_reply(reply)
{m_waitTimeOut = false;m_isWaitTimeOut = false;
}NetDataListenerThread::~NetDataListenerThread()
{}void NetDataListenerThread::run()
{m_isWaitTimeOut = waitForConnect();
}bool NetDataListenerThread::waitForConnect()
{QEventLoop eventLoop;QTimer * timer = nullptr;m_waitTimeOut = false;bool bWaitTimeOut = false;if (m_TimeOutms > 0){timer = new QTimer;connect(timer, SIGNAL(timeout()), this, SLOT(slot_waitTimeout()));timer->setSingleShot(true);timer->start(m_TimeOutms);connect(this, SIGNAL(sig_waitTimeout()), &eventLoop, SLOT(quit()));}connect(mManager, SIGNAL(finished(QNetworkReply *)), &eventLoop, SLOT(quit()));if (m_reply != nullptr){connect(m_reply, SIGNAL(readyRead()), &eventLoop, SLOT(quit()));}eventLoop.exec();if (timer != nullptr){timer->stop();delete timer;timer = nullptr;}bWaitTimeOut = m_waitTimeOut;m_waitTimeOut = false;return !bWaitTimeOut;
}void NetDataListenerThread::slot_waitTimeout()
{m_waitTimeOut = true;emit sig_waitTimeout();
}bool NetDataListenerThread::getIsWaitTimeOut() const
{return m_isWaitTimeOut;
}WebHelp * WebHelp::serverHelp = nullptr;
WebHelp::Dispose WebHelp::disp;WebHelp::WebHelp(QObject *parent):QObject(parent)
{m_user = SetupWidget::gConfig.user();m_pwd = SetupWidget::gConfig.pwd();manager = new QNetworkAccessManager();m_errCode= QNetworkReply::NoError;connect(manager, SIGNAL(authenticationRequired(QNetworkReply*,QAuthenticator*)),SLOT(provideAuthenication(QNetworkReply*,QAuthenticator*)));
}WebHelp::~WebHelp()
{manager->deleteLater();}WebHelp *WebHelp::getInstance()
{if(serverHelp==nullptr){serverHelp = new WebHelp();}return serverHelp;
}QNetworkReply::NetworkError WebHelp::sendGetRequest(QString urlStr, QByteArray & ba,int timeOutms)
{QNetworkReply::NetworkError retError = QNetworkReply::NoError;m_errCode= QNetworkReply::NoError;QNetworkRequest request;QUrl url(urlStr);request.setUrl(url);QNetworkReply *reply = manager->get(request);connect(reply,static_cast<void (QNetworkReply::*)(QNetworkReply::NetworkError)>(&QNetworkReply::error),this,&WebHelp::slot_error);QEventLoop eventLoop;NetDataListenerThread * thread = new NetDataListenerThread(manager,reply,timeOutms);connect(thread, &NetDataListenerThread::finished,&eventLoop,&QEventLoop::quit);thread->start();eventLoop.exec();if(thread->getIsWaitTimeOut()){ba = reply->readAll();}else{m_errCode=QNetworkReply::TimeoutError;}thread->deleteLater();delete reply;delete thread;thread = nullptr;retError = m_errCode;m_errCode= QNetworkReply::NoError;return retError;
}QNetworkReply::NetworkError WebHelp:: sendPostRequest(QString website, const QByteArray &postBa, QByteArray &retBa, int timeOutms)
{QString urlStr =website;QNetworkReply::NetworkError retError = QNetworkReply::NoError;m_errCode= QNetworkReply::NoError;QNetworkRequest request;QSslConfiguration config;config.setPeerVerifyMode(QSslSocket::VerifyNone);config.setProtocol(QSsl::TlsV1SslV3);request.setSslConfiguration(config);QUrl url(urlStr);request.setUrl(url);request.setHeader( QNetworkRequest::ContentTypeHeader, QVariant(QString("text/xml;charset=utf-8")));request.setHeader(QNetworkRequest::ContentLengthHeader, QVariant(qulonglong(postBa.size()) ));request.setAttribute(QNetworkRequest::CacheLoadControlAttribute, QVariant( int(QNetworkRequest::AlwaysNetwork)));QNetworkReply *reply = manager->post(request,postBa);connect(reply,static_cast<void (QNetworkReply::*)(QNetworkReply::NetworkError)>(&QNetworkReply::error),this,&WebHelp::slot_error);QEventLoop eventLoop;NetDataListenerThread * thread = new NetDataListenerThread(manager,reply,timeOutms);connect(thread, &NetDataListenerThread::finished,&eventLoop,&QEventLoop::quit);thread->start();eventLoop.exec();if(thread->getIsWaitTimeOut()){retBa = reply->readAll();}else{m_errCode=QNetworkReply::TimeoutError;}thread->deleteLater();delete reply;delete thread;thread = nullptr;retError = m_errCode;m_errCode= QNetworkReply::NoError;return retError;
}void WebHelp::slot_error(QNetworkReply::NetworkError code)
{m_errCode = code;
}void WebHelp::provideAuthenication(QNetworkReply *, QAuthenticator *ator)
{ator->setUser(m_user);ator->setPassword(m_pwd);
}WebHelp::Dispose::~Dispose()
{if(WebHelp::serverHelp!=nullptr){delete WebHelp::serverHelp;WebHelp::serverHelp=nullptr;}
}

四，备注

（1），如果网站需要用户名和密码需要再此处设置

void WebHelp::provideAuthenication(QNetworkReply *, QAuthenticator *ator)
{ator->setUser(m_user);ator->setPassword(m_pwd);
}

（2），两个 header 可能略有不同

request.setHeader( QNetworkRequest::ContentTypeHeader, QVariant(QString("text/xml;charset=utf-8")));request.setHeader(QNetworkRequest::ContentLengthHeader, QVariant(qulonglong(postBa.size()) ));
