Get indefinite amount of string params from ASP.NET Core route

Question

I have a basic HttpGet method where people can add an indefinite amount of string params. So basically this means that you can navigate to api/controller/foo , api/controller/foo/bar , api/controller/foo/bar/biz , etc

I tried going at it like below but this doesn't seem to work

[HttpGet("{container}/{prefixes}")]
public async Task<ActionResult<string>> Get(string container, params string[] prefixes)

Answer 1

You can use a catch-all template parameter and split the path yourself to solve your problem:

[HttpGet("{container}/{*prefixPath}")]
public async Task<ActionResult<string>> Get(string container, string prefixPath)
{
    string[] prefixes = prefixPath?.Split('/');
    ...
}
