qt中post和get请求

1.头文件

#include <QNetworkAccessManager>
#include <QNetworkReply>
#include <QEventLoop>
#include <QTextCodec>

2.GET请求

QString QtGuiApplication1::getRequest(QString url)
{
    QNetworkRequest request;
    QNetworkAccessManager* naManager = new QNetworkAccessManager(this);
    QUrl strUrl = url;
    request.setUrl(strUrl);
    request.setRawHeader("Content-Type", "charset='utf-8'");
    request.setRawHeader("Content-Type", "application/json");
    QNetworkReply* reply = naManager->get(request);
    QByteArray responseData;
    QEventLoop eventLoop;
    connect(naManager, SIGNAL(finished(QNetworkReply*)), &eventLoop, SLOT(quit()));
    eventLoop.exec();
    QTextCodec* codec = QTextCodec::codecForName("utf8");
    QString strReply = codec->toUnicode(reply->readAll());
    reply->deleteLater();
    return strReply;
}

3.POST请求

void QtGuiApplication1::postRequest(QString url, QByteArray array)
{
    QNetworkRequest request;
    QNetworkAccessManager* naManager = new QNetworkAccessManager(this);
    QUrl strUrl = url;
    request.setUrl(strUrl);
    request.setRawHeader("Content-Type", "charset='utf-8'");
    request.setRawHeader("Content-Type", "application/json");

    QNetworkReply* reply = naManager->post(request, array);
    QByteArray responseData;
    QEventLoop eventLoop;
    connect(naManager, SIGNAL(finished(QNetworkReply*)), &eventLoop, SLOT(quit()));
    eventLoop.exec();
    QTextCodec* codec = QTextCodec::codecForName("utf8");
    QString strReply = codec->toUnicode(reply->readAll());
    reply->deleteLater();
}
