有没有办法在路由中间添加一个可选参数？
示例路由:
/things/entities/
/things/1/entities/
我试过这个，但不管用:
get('things/{id?}/entities', 'MyController@doSomething');
我知道我能做到.
get('things/entities', 'MyController@doSomething');
get('things/{id}/entities', 'MyController@doSomething');
... 但我的问题是:Can I add an optional parameter in the middle of a route?
不需要.可选参数需要转到路由的末尾，否则路由将不知道如何将URL与路由匹配.您已经实施的是正确的方法:
get('things/entities', 'MyController@doSomething');
get('things/{id}/entities', 'MyController@doSomething');
You could try doing it with one route:
get('things/{id}/entities', 'MyController@doSomething');
如果你想获取所有东西的实体，就通过* or 0，但我称之为黑客.
There are some other hacks that could allow you to use one route for that, but it will increase the complexity of your code and it's really not worth it.
