QWebView::Load https problem

I have a URL,

I am calling QWebView::load(); To show this page.
But this page load failed.

I assume you have not installed a version of the third-party OpenSSL libraries required to support HTTPS. One place you can get pre-built libraries for Windows is http://slproweb.com/products/Win32OpenSSL.html. For OS X there might be an equivalent binary distribution. You could build OpenSSL for yourself.
