You would really need a complete render engine for this to work, and I doubt any of them would run on Google App Engine. 您确实需要一个完整的渲染引擎来使其正常工作，我怀疑其中任何一个都可以在Google App Engine上运行。 I think it would be best to use an external API such as thumbalizr . 我认为最好使用诸如thumbalizr的外部API。 Also have a look at BrowserShots . 还可以看看BrowserShots 。

i would use a public webservice for that. 我会为此使用公共网络服务。 something like girafa . 类似吉拉法。 if you need shots for all browsers browsershots is the one for you. 如果您需要所有浏览器的快照，那么browsershots就适合您。
