本文介绍了Flask URL路由:将多个URL路由到同一功能的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在使用Flask 0.9.

I am working with Flask 0.9.

现在我想将三个URL路由到相同的功能:

Now I want to route three urls to the same function:

/item/<int:appitemid> /item/<int:appitemid>/ /item/<int:appitemid>/<anything can be here>

<anything can be here>部分将永远不会在函数中使用.

The <anything can be here> part will never be used in the function.

我必须复制相同的函数两次才能实现此目标:

I have to copy the same function twice to achieve this goal:

@app.route('/item/<int:appitemid>/') def show_item(appitemid): @app.route('/item/<int:appitemid>/<path:anythingcanbehere>') def show_item(appitemid, anythingcanbehere):

会有更好的解决方案吗?
