根因分析

多个路由装饰器应用于同一函数名，或同一端点名称注册了两次视图函数。

English

Multiple route decorators applied to the same function name or a view function registered twice with the same endpoint name.

generic

解决方案

  1. 95% 成功率 
    Specify different endpoint names in each decorator: @app.route('/a', endpoint='a_func') and @app.route('/b', endpoint='b_func')
  2. 90% 成功率 
    Use unique function names for each route: def index_a(): return 'A' and def index_b(): return 'B'

无效尝试

常见但无效的做法:

  1. 60% 失败

    The endpoint defaults to the function name; if the path is the same, Flask still sees a conflict if the old function isn't removed.

  2. 80% 失败

    Flask uses the function name as the endpoint by default, causing overwrite unless explicit endpoint is given.
