瓶可选的url参数不起作用

问题描述

  @ mod.route（'/ participation /< survey_id> /'，defaults = {'work_id'：None}，methods = ['GET'，'POST']） 
 @ mod.route（'/ pariicipate /< survey_id> /< work_id>'方法= ['GET'，'POST']）
 def参与（survey_id，work_id）：
 / * do_something .. * / 
  

我可以访问 http：/ / localhost：5000 / participa / 512dc365fe8974149091be1f 或 http：// localhost：5000 / participa / 512dc365fe8974149091be1f /
如果我启动我可以看到 work_id = None 。

如果我尝试 http：/ / localhost：5000 / participa / 512dc365fe8974149091be1f / 512dc365fe8974149091be1f 或 http：// localhost：5000 / participa / 512dc365fe8974149091be1f / 512dc365fe8974149091be1f / / p>

为什么会发生这种情况？有没有什么我做了错误的路由规则？

解决方案

你的第二条路线有一个错字：）

  @ mod.route（'/ pariicipate /< survey_id> /< work_id>，methods = ['GET'，'POST ']）
  

应该是

<$ p $ >

@mod.route('/participate/<survey_id>/', defaults = {'work_id':None}, methods = ['GET','POST'])
@mod.route('/pariicipate/<survey_id>/<work_id>', methods = ['GET', 'POST'])
def participate(survey_id, work_id):
   /* do_something .. */

I can access http://localhost:5000/participate/512dc365fe8974149091be1f or http://localhost:5000/participate/512dc365fe8974149091be1f/and if I fire up a debugger I can see that work_id = None.

If I try http://localhost:5000/participate/512dc365fe8974149091be1f/512dc365fe8974149091be1for http://localhost:5000/participate/512dc365fe8974149091be1f/512dc365fe8974149091be1f/ I get 404.

why is this happening? Is there something I've done wrong with routing rules?

解决方案

Your second route has a typo in it :)

@mod.route('/pariicipate/<survey_id>/<work_id>', methods = ['GET', 'POST'])

should be

@mod.route('/participate/<survey_id>/<work_id>', methods = ['GET', 'POST'])
