其余-API网址中的“：”和“ {}”有什么区别？

Question

I have seen two styles ( /api/users/:uid and /api/users/{uid} ) when designing API:

Do they have different meanings? Or just styles?

Answer 1

Both examples refer to captured elements of a submitted URL. When your service receives a request in the form of /api/users/foo , the controller (or whatever piece of code gets invoked to process the request) will receive a request parameter named uid with value foo . Whether it's prefixed with a colon, or wrapped in braces depends on the syntax of the particular framework you're using.
