Headless browser in Azure functions JavaScript?

Question

我尝试使用phantomjs，但显然不受支持，有没有办法使用javascript中的azure函数抓取网站？

Answer 1

There are many restrictions on Azure App Service (includes WebApps, Function Apps), such as Win32k.sys (User32/GDI32) Restrictions . So some packages are not supported on Azure App Service, which like PhantomJS/puppteer be required to start a headless browser which needs GDI support to communicate with javascript/nodejs to get DOM node.

You can scrape a static web page or only HTML via Node http.ClientRequest or Request package in Function App. If to scrape a DOM node of a web page dynamically, the only way is using PhantomJS/puppteer on Azure VM, not Function Apps.
