The client requests a shared network login status QNetworkCookieJar QNetworkCookie network module (seven)

A brief
1. Internet companies c / s architecture are done display and exchange data through the network interface or the browser request to access the server.
2. The client authenticates the server based account password link.
3. After verifying the identity of the server will be successful in writing client-side cookies back.
4.QNetworkAccessManager use cookies were QNetworkCookieJar management of all requests QNetworkAccessManager will use its internal QNetworkCookieJar

5. If you want to use QWebEngineView interface access requires authentication URL, such as Taobao, Jingdong and so need to log in. At this time, the above-described need to share cookies in QWebEngineView. Specific methods are as follows:
QWebEngineView :: QWebEnginePage CookieStore :: :: :: QWebEngineProfile the setCookie (const QNetworkCookie & Cookie, Origin = const QUrl & QUrl ()); the url is the addition of authentication to access the cookies
