如何从端点/规则获取视图功能？ [英] How can I get the view function from an endpoint/rule?

问题描述

在Flask（或werkzeug）中，当我拥有的是规则时，如何获得视图函数？ （或该规则的端点）？

解决方案

Werkzeug仅存储规则映射，每个规则都有一个端点。通过将每个端点与一个函数相关联，Flask添加到Werkzeug中。使用 app.view_functions dict从端点名称获取视图函数。

 ＃假设r是规则
f = app.view_functions [r.endpoint] 
  

In Flask(or werkzeug), how can I get the view function when all I have is the Rule? (or the Endpoint from that rule)?

解决方案

Werkzeug only stores a map of rules, each of which has an endpoint. Flask adds to Werkzeug by associating each endpoint with a function. Use the app.view_functions dict to get the view function from the endpoint name.

# assuming r is a Rule
f = app.view_functions[r.endpoint]
