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/ 如果我启动调试器，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/，我会得到404。

为什么会这样？我有没有做过路由规则的错误？

Answer 1

你的第二条路线中有拼写错误：）

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

应该是

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

flask可选url参数不起作用
