如何使用QWebEngineView忽略SSL证书错误

Question

如何在QWebEngineView中通过C++忽略和启用/禁用SSL证书错误？我发现QWebEnginePage有虚拟方法证书Error，但无法通过QWebEngineView访问？

Answer 1

我现在的解决方案是从QWebEnginePage派生，覆盖方法certificateError，并通过调用setPage将派生类的实例传递给QWebEngineView。如果有人感兴趣，这里有一个例子。

网页.h

#ifndef WEBPAGE_H
#define WEBPAGE_H
#include <QWebEnginePage>
class WebPage : public QWebEnginePage
{
Q_OBJECT
public:
explicit WebPage(QWidget *parent = 0);
protected:
bool certificateError(const QWebEngineCertificateError &error) override;
};
#endif // WEBPAGE_H

网页.cpp

#include "webpage.h"
WebPage::WebPage(QWidget *parent) :
QWebEnginePage(parent)
{
}
bool WebPage::certificateError(const QWebEngineCertificateError &error)
{
// TODO: conditional treatment
return error.isOverridable();
}

用法：

auto webView = new QWebEngineView(this);
auto webPage = new WebPage(this);
webView->setPage(webPage);

在QT 6中，此插槽已更改为插槽。您可以连接它并调用acceptCertificate:

connect(this, &WebPage::certificateError, this, &WebPage::onCertificateError);

void WebPage::onCertificateError(QWebEngineCertificateError
error) {
#if IGNORE_SSL_ERRORS   qWarning() << "WebPage:: ignoring certificate error: " << error.description();  
auto mutableError = const_cast<QWebEngineCertificateError&>(error);
mutableError.acceptCertificate();     
#endif   
qCritical() << "WebPage:: certificate error: " << error.description();   }
