烧瓶可选的URL参数不工作

Question

@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 .. */ 

我可以访问http://localhost:5000/participate/512dc365fe8974149091be1f或http://localhost:5000/participate/512dc365fe8974149091be1f/ 如果我火了一个调试器，我可以看到work_id = None。

如果我尝试http://localhost:5000/participate/512dc365fe8974149091be1f/512dc365fe8974149091be1f或http://localhost:5000/participate/512dc365fe8974149091be1f/512dc365fe8974149091be1f/我得到404

为什么会出现这种情况？有没有我做了路由规则的错误？

Answer 1

你的第二条路线有一个错字在它:)

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

应该

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