如何在 QtWebKit 中获取响应
我是 QtWebKit 的初学者，我构建了加载页面的简单 Web 框架（服务器端） 当我从这个页面提交数据时，我喜欢在 C++ 端捕获来自服务器的响应字符串 我该怎么做？
im beginner with QtWebKit i build simple web frame that loaded page ( server side )

我对 Qt（我是新手）进行了修改，找到了一种捕获 WebKit 下载的所有资源的方法。具体方法如下：
1) 创建您自己的 QNetworkAccessManager 子类
2) 在派生类中，重写虚函数 createRequest
3) 调用基类实现以获取响应对象。之后你可以看看
URL（或其他参数）并确定是否需要捕获该特定资源
4) 如果需要 - 将readyRead信号连接到某个将捕获数据的插槽
5) 在该插槽中调用peek函数来读取数据，以便WebKit也将获取数据
6) 创建 QWebPage 对象后，调用 setNetworkAccessManager 并传递步骤 1 中新创建的子类实例)
就这样 - 享受吧！
I tinkered around with Qt (which I'm new to) and found a way to catch all resources downloaded by WebKit. Here's how:
1) Create your own subclass of QNetworkAccessManager
2) In your derived class, override virtual function createRequest
3) Call base class implementation to get the response object. After that you can look at
the URL (or other parameters) and determine whether you need to capture that particular resource or not
4) if you do - connect readyRead signal to some slot that will capture the data
5) in that slot call peek function to read data so that WebKit will get the data also
6) After creating QWebPage object, call setNetworkAccessManager and pass a newly created instance of your subclass from step 1)
That's it - enjoy!
您可以使用
QNetworkReply类。QWebPage实例具有networkAccessManager()方法返回QNetworkAccessManager实例能够发送请求和接收响应。您需要查找其
finished信号。void QNetworkAccessManager::finished (QNetworkReply * 回复)QNetworkReply又是QIODevice因此您可以调用它的readAll()方法以接收响应数据。您可能还会发现这个问题很有用。
You can use
QNetworkReplyclass for it.QWebPageinstances havenetworkAccessManager()method that returns aQNetworkAccessManagerinstance capable of sending requests and receiving responses.You need to look for its
finishedsignal.void QNetworkAccessManager::finished ( QNetworkReply * reply )QNetworkReplyin its turn is an inheritor ofQIODevicetherefore you are able to call itsreadAll()method in order to receive the response data.You may also find this question useful.
