QT 发送HTTP请求

2019独角兽企业重金招聘Python工程师标准>>>

今天领导让研究一下QT程序请求我写的网站后台数据，本人QT小白只写过三个小工具，所以到网上找了一些资料并写了一个小demo：

HTTP请求在QT中相应的类为NetworkRequest，HTTP响应的类为NetworkReply。发送请求需要创建一个管理器实例QNetworkAccessManager。可以调用它的get、post等方法发送get、post等HTTP请求。

class HttpTest : public QObject{
Q_OBJECT
public:
    void testGet(); //发送http请求
public slots:
    void replyFinish(QNetworkReply*); //用于处理响应返回的数据
};

void HttpTest::testGet(){
    QNetworkAccessManager* manager = new QNetworkAccessManager(this);
    QNetworkRequest request;

    request.setUrl(QUrl("http://192.168.1.1:8080/pvstation/status"));
    QNetworkReply* reply = manager->get(request);
    connect(manager, SIGNAL(finished(QNetworkReply*)), this, SLOT(replyFinish(QNetworkReply*)));
}


void HttpTest::replyFinish(QNetworkReply* reply)
{
    qDebug()<readAll();
}
