问题
I have a URL in my app.js containing routes. lets say the url is:
/api/:opt1/:opt2/:opt3/users
I want that my url will work in any case, i should able to ignore the optional parameters (opt1, opt2 or opt3, may be all or few). How can I achieve this.
Is there any way that I can call $location.path('/users'), and I can specify also what are the values of the optional parameters?
回答1:
Optional route parameters are marked with ?, like this:
`/users/:id?`
Then this route matches both /users and /users/1 paths
