如何使用QWebEngineUrlRequestInterceptor [英] How to use QWebEngineUrlRequestInterceptor

问题描述

我需要拦截我们的WebEngine qml组件中的请求在我们的Qt应用程序。

我已经找到文档QWebEngineUrlRequestInterceptor这似乎只做这里 http://doc.qt.io/qt-5/qwebengineprofile.html#details 此处 http://doc.qt.io/qt-5/qwebengineurlrequestinterceptor。 html＃details 。但是我还没有找到任何关于如何在Qt / C ++中这样做的代码示例。

任何帮助是值得赞赏的。

解决方案

这是我连接QWebEngineUrlRequestInterceptor的解决方案：

.h文件

  class WebUrlRequestInterceptor：public QWebEngineUrlRequestInterceptor 
 {
 Q_OBJECT 
 
 public：
 WebUrlRequestInterceptor p = Q_NULLPTR）; 
 void interceptRequest（QWebEngineUrlRequestInfo& info）; 
}; 
  

.cpp文件

  WebUrlRequestInterceptor :: WebUrlRequestInterceptor（QObject * p）
：QWebEngineUrlRequestInterceptor（p）
 {
 
} 
 void WebUrlRequestInterceptor :: interceptRequest（QWebEngineUrlRequestInfo& ; info）{
 QString rsrct =; 
 switch（info.resourceType（））{
 case 0：rsrct =ResourceTypeMainFrame = 0，//顶级页面; break; 
 case 1：rsrct =ResourceTypeSubFrame，// frame or iframe; break; 
 case 2：rsrct =ResourceTypeStylesheet，//一个CSS样式表; break; 
 case 3：rsrct =ResourceTypeScript，//外部脚本; break; 
 case 4：rsrct =ResourceTypeImage，// a image（jpg / gif / png / etc）; break; 
 case 5：rsrct =ResourceTypeFontResource，// a font; break; 
 case 6：rsrct =ResourceTypeSubResource，// an other subresource。; break; 
 case 7：rsrct =ResourceTypeObject，//插件的对象（或嵌入）标签，; break; 
 case 8：rsrct =ResourceTypeMedia，// a media resource。; break; 
 case 9：rsrct =ResourceTypeWorker，//专用工作程序的主要资源。 
 case 10：rsrct =ResourceTypeSharedWorker，//共享worker的主资源。 
 case 11：rsrct =ResourceTypePrefetch，//明确请求的预取; break; 
 case 12：rsrct =ResourceTypeFavicon，// a favicon; break; 
 case 13：rsrct =ResourceTypeXhr，// a XMLHttpRequest; break; 
 case 14：rsrct =ResourceTypePing，// ping请求< a ping>; break; 
 case 15：rsrct =ResourceTypeServiceWorker，//服务工作者的主要资源。 
 case 16：rsrct =ResourceTypeUnknown; break; 
 
默认值：rsrct =未知类型; break; 
} 
 
 qDebug（）<<\t<< Q_FUNC_INFO<<：\\\
\t\t< WebUrlRequestInterceptor :: interceptRequest<< info.requestMethod（）
<<\r\\\
<< info.requestUrl（）<< rsrct<<\r\\\
; 
  WebUrlRequestInterceptor * wuri = new WebUrlRequestInterceptor（）; 
 QWebEngineProfile :: defaultProfile（） - > setRequestInterceptor（wuri）; 
  
 
I need to intercept requests made in our WebEngine qml component in our Qt application.

I have found documentation on QWebEngineUrlRequestInterceptor which seems to do just this here http://doc.qt.io/qt-5/qwebengineprofile.html#details and here http://doc.qt.io/qt-5/qwebengineurlrequestinterceptor.html#details. However I haven't found any code examples on how to do this in Qt/C++.

Any help is appreciated.
解决方案
Managed to puzzle it together with the help of this post: https://forum.qt.io/topic/69135/how-to-send-network-requests-in-qwebengine/2

This is my solution to hook up a QWebEngineUrlRequestInterceptor:

.h file
class WebUrlRequestInterceptor : public QWebEngineUrlRequestInterceptor
{
    Q_OBJECT

public:
    WebUrlRequestInterceptor(QObject *p = Q_NULLPTR);
    void interceptRequest(QWebEngineUrlRequestInfo &info);
};
.cpp file
WebUrlRequestInterceptor::WebUrlRequestInterceptor(QObject *p)
  :QWebEngineUrlRequestInterceptor(p)
{

}
void WebUrlRequestInterceptor::interceptRequest(QWebEngineUrlRequestInfo &info) {
    QString rsrct = "";
    switch(info.resourceType()){
        case 0:rsrct="ResourceTypeMainFrame = 0, // top level page";break;
        case 1:rsrct="ResourceTypeSubFrame, // frame or iframe";break;
        case 2:rsrct="ResourceTypeStylesheet, // a CSS stylesheet";break;
        case 3:rsrct="ResourceTypeScript, // an external script";break;
        case 4:rsrct="ResourceTypeImage, // an image (jpg/gif/png/etc)";break;
        case 5:rsrct="ResourceTypeFontResource, // a font";break;
        case 6:rsrct="ResourceTypeSubResource, // an other subresource.";break;
        case 7:rsrct="ResourceTypeObject, // an object (or embed) tag for a plugin,";break;
        case 8:rsrct="ResourceTypeMedia, // a media resource.";break;
        case 9:rsrct="ResourceTypeWorker, // the main resource of a dedicated worker.";break;
        case 10:rsrct="ResourceTypeSharedWorker, // the main resource of a shared worker.";break;
        case 11:rsrct="ResourceTypePrefetch, // an explicitly requested prefetch";break;
        case 12:rsrct="ResourceTypeFavicon, // a favicon";break;
        case 13:rsrct="ResourceTypeXhr, // a XMLHttpRequest";break;
        case 14:rsrct="ResourceTypePing, // a ping request for <a ping>";break;
        case 15:rsrct="ResourceTypeServiceWorker, // the main resource of a service worker.";break;
        case 16:rsrct="ResourceTypeUnknown";break;

        default : rsrct="Unknown type";break;
    }

  qDebug()<<"\t"<<Q_FUNC_INFO<<":\n\t\t" << "WebUrlRequestInterceptor::interceptRequest    " <<info.requestMethod()
         <<"\r\n  "<<info.requestUrl()<<"   "<<rsrct      <<"\r\n";

}
main.cpp file
WebUrlRequestInterceptor *wuri = new WebUrlRequestInterceptor();
    QWebEngineProfile::defaultProfile()->setRequestInterceptor(wuri);
