再会。我在facebook上做了一个申请。它有画布 URL：http: //v-skladchinu.ru/user/main_choose/
画布页面：http ://apps.facebook.com/f-two-apps
和网站网址：http: //v-skladchinu.ru
但我无法通过画布页面 url 看到任何内容。只是空白页。
t even try to call my server for the application. I put a breackpoint to my code and it looks like facebook doesn在我检查了这种情况之后，我明白了，facebook根本不需要 http://v-skladchinu.ru/user/main_choose/页面。
为什么会这样？
You need a valid SSL certificate, not just a self-signed one. a self-signed certificate is telling the browser that you trust yourself, whereas a valid SSL certificate requires another website to verify you're not a spoof.
Just by googleing free SSL certificates, you get some good results. For example, http://cert.startcom.org/ gives you free SSL authentication, and even shows you how to set it up step by step, so I do recommend them. They even insure it for $10'000, which for me is the icing on the cake.
However, if you find out they don't suit your needs there are thousands of other free providers to choose from.
您的页面似乎存在 SSL 证书问题。
我已经尝试使用来自https://v-skladchinu.ru:8443/的应用程序，如果我在 Chrome 的警告上单击“继续”，它就可以正常工作。
您可能想尝试一些其他免费的 SSL 网站，例如heroku.com。
