hello大皮——使用Qt访问Python Web服务 (使用Qt获取网页数据)

#include "widget.h"#include "ui_widget.h"
Widget::Widget(QWidget *parent) :    QWidget(parent),    ui(new Ui::Widget){    ui->setupUi(this);
    //请求python服务数据    mp_clsManager = new QNetworkAccessManager(this);    connect(mp_clsManager,SIGNAL(finished(QNetworkReply*)),            this,SLOT(slot_replyFinished(QNetworkReply*)));}
Widget::~Widget(){    delete ui;}
void Widget::slot_replyFinished(QNetworkReply *reply){    //在槽中接收python服务信息    if(reply->error() == QNetworkReply::NoError)    {        QString str(reply->readAll());
        qDebug() << "str is :" << str;
    }}
void Widget::on_pbn_sendMsg_clicked(){    QString postRequest  = QString("http://%1:8080/hello?str=你好，大皮")            .arg("localhost");    mp_clsManager->get(QNetworkRequest(QUrl(postRequest)));}
