qWebEngine如何判断ajax加载完成

qWebEngine如何判断ajax加载完成 有什么信号吗 或者通过什么其他办法

使用QWebEngineView 它是一个抽象详细看代码：

#include <QWebEngineUrlRequestInterceptor>
#include <QDebug>

class RequestInterceptor : public QWebEngineUrlRequestInterceptor
{
public:
    explicit RequestInterceptor(QObject * parent = Q_NULLPTR) : QWebEngineUrlRequestInterceptor(parent) {}
    virtual void interceptRequest(QWebEngineUrlRequestInfo & info) Q_DECL_OVERRIDE;
};

void RequestInterceptor::interceptRequest(QWebEngineUrlRequestInfo & info)
{
    // Intercepting the requested URL
    QUrl url = info.requestUrl();
    qDebug() << "Request URL: " << url;

    // Optionally redirect the request URL but it only works for requests 
    // without payload data such as GET ones
    info.redirect(QUrl("https://www.google.com"));

    // Set HTTP header
    QByteArray httpHeaderName = "SomeHeaderName";
    QByteArray httpHeaderValue = "SomeHeaderValue";
    info.setHttpHeader(httpHeaderName, httpHeaderValue);
}

然后你需要在QWebEngineProfile中为特定的QWebEnginePage注册指向此拦截器的指针,如下所示：

QWebEngineView * view = new QWebEngineView;
RequestInterceptor * interceptor = new RequestInterceptor(view);
QWebEngineProfile * profile = new QWebEngineProfile(view);
profile->setRequestInterceptor(interceptor);
QWebEnginePage * page = new QWebEnginePage(profile, view);
view->setPage(page);

网页如果是你们自己写的话
也可以使用QWebEngineView提供的js和c++的通信的方式

这个是加载前，不是加载完成。。。。大哥们看清楚问题
