1)龙卷风给我这个错误
1) Tornado give me that error

2)Apache运行良好，并向我展示了我想要的.
2) Apache works good and show me what I want.
我做错了什么?，似乎龙卷风不能与{{}}运算符一起使用?
推荐答案
RequestHandler.render 用于处理Tornado模板，该模板使用 {{}} 进行表达式替换(与Angular相同).如果您使用Angular模板，则可以将此HTML用作静态文件，而不是通过模板引擎运行它，也可以将 {{！"替换为大括号.龙卷风将删除感叹号，其余部分将由角钢处理.
RequestHandler.render is for processing Tornado templates, which use {{ }} for expression substitution (same as Angular). If you use Angular templates, you can either serve this HTML as a static file instead of running it through the template engine, or replace the opening braces with {{!. Tornado will remove the exclamation point and leave the rest alone to be processed by angular.
