Qt - 如何使用 QNetworkAccessmanager 获取响应文本
这是我的代码：
Widget::Widget()
{
manager = new QNetworkAccessManager(this);
connect(manager, SIGNAL(finished(QNetworkReply*)),this, SLOT(replyFinished(QNetworkReply*)));
manager->get(QNetworkRequest(QUrl("http://qt.nokia.com")));
}
void Widget::replyFinished(QNetworkReply* reply)
{
//some other code here
}
我希望 reply 会有一些像 getrespnsetext() 这样的方法，但它不是......
有人能给我举个例子吗，我需要的只是打印出响应文本（有没有像 Javascript Ajax 那样的方式）
感谢您的帮助！
Here is my code:
Widget::Widget()
{
manager = new QNetworkAccessManager(this);
connect(manager, SIGNAL(finished(QNetworkReply*)),this, SLOT(replyFinished(QNetworkReply*)));
manager->get(QNetworkRequest(QUrl("http://qt.nokia.com")));
}
void Widget::replyFinished(QNetworkReply* reply)
{
//some other code here
}
I hope that reply will have some method like getrespnsetext() but it not...
Can some one show me an example, all the thing i need is print out the response text (is ther any way like in Javascript Ajax)
Thanks for your help!

您只需在
replyFinished(...)函数中使用reply->readAll()即可读取所有返回的文本。它返回一个QByteArray，因此您可以从那里做任何您想做的事情。You only need to use
reply->readAll()inside thereplyFinished(...)function to read all the returned text. It returns aQByteArray, so you can do wathever you want from there.此处查看
QNetworkReply的文档 ，特别是在完成信号处，它提到您可以使用 readAll() 来获取所有数据的 QByteArray 。假设您知道此类转换是否有效，QString确实有一个采用QByteArray作为参数的构造函数，如文档 此处。Looking at the documentation for
QNetworkReplyhere, specifically at the finished signal, it mentions that you can usereadAll()to get aQByteArrayof all of the data. Assuming that you know whether or not such a conversion is valid,QStringdoes have a constructor that takes aQByteArrayas a parameter, as documented here.
