Micronaut is decoding the ‘+’ in the path variable passed to the controller code

[sxsubram]

Expected Behavior

In my unit test with I have

URI = "/test/1.0/" +
"024-02-07T00:30:48.014+00:00?time=024-02-07T00:30:48.014+00:00"

The controller has
@Get(uris = {“/test/{version}/{+resourcePath}“})

The resourcePath variable and query param should have the raw format value
resource variable path = 024-02-07T00:30:48.014+00:00
query param = 024-02-07T00:30:48.014+00:00
for downstream processing to work.

Actual Behaviour

@Get(uris = {“/test/{version}/{+resourcePath}“})

In my unit test with

URI = "/test/1.0/" +
"024-02-07T00:30:48.014+00:00?time=024-02-07T00:30:48.014+00:00"

client setting unencoded PATH = /test/1.0/024-02-07T00:30:48.014+00:00

resource variable path = 024-02-07T00:30:48.014 00:00 //'+' is replaced with ' '
from http req : path = /test/1.0/024-02-07T00:30:48.014+00:00
from http req : query param time = 024-02-07T00:30:48.014 00:00 //'+' is replaced with ' '

I would like to get the resourcePath and query param in the raw format for downstream processing.

Steps To Reproduce

@Controller
public class HelloController {
    @Get(uris = {"/test/{version}/{+resourcePath}" })
    @Produces(MediaType.ALL)
    public HttpResponse<?> triggerGet(@PathVariable("version") @Nullable String version,
                                      @PathVariable("resourcePath") @Nullable String resourcePath,
                                      HttpRequest httpRequest) {

        String path = httpRequest.getPath(); //This is the actual path
        return HttpResponse.ok("resource variable path = " + resourcePath + "\n" +
                " from http req : path = " + httpRequest.getPath() + "\n" +
                " from http req : query param time = " + httpRequest.getParameters().get("time"));
    }

@Test
    public void testPathUrlUnEncoded() {
        HttpRequest<?> req = HttpRequest.GET("/test/1.0/" +
                "024-02-07T00:30:48.014+00:00?time=024-02-07T00:30:48.014+00:00");
        String path = req.getPath();
        System.out.println("client setting unencoded PATH = " + path + "\n");
        System.out.println(client.toBlocking().retrieve(req));
    }

(https://datatracker.ietf.org/doc/html/rfc2396) - Within a path segment, the characters
"/", ";", "=", and "?" are reserved, so + in a path should not be changed

[yawkat]

not sure we can change the existing behavior, but it seems reasonable to add an api to get the unencoded path component.

Hello @yawkat - Is there an ETA for this fix?
