"wildcard route conflicts with existing children"

[wodim]

router.GET("/:something/", Blabla)
router.GET("/:something/else", Bleble)
router.GET("/:something/:different/:again", Blibli)

panic: wildcard route ':different' conflicts with existing children in path '/:something/:different/:again'

Am I doing something wrong or is this simply not allowed?

#1301 , so it's not allowed

[wodim]

Wow, that is terrible.

[thinkerou]

expected, thanks! you should re-write your route.

[wodim]

Saying it's "expected" makes it double terrible, because it means you will never get around to fix it.

There is no way Gin should confuse Bleble with Blibli: Bleble has two slashes, and Blibli has three!

In the end I had to write my own router like this:

router.GET("/", ViewHome)
router.GET("/:first", ViewRouterOne)
router.GET("/:first/:second", ViewRouterTwo)
router.GET("/:first/:second/:third", ViewRouterThree)
router.GET("/:first/:second/:third/:fourth", ViewRouterFour)

Then from those functions you can redirect requests to the correct view functions. I hope this is useful to someone.

how this routes cause conflict

pGroup.POST("/fork", controllers.Fork)
pGroup.POST("/:id/process", controllers.processN)

Am I the only one who doesn't understand why something so basic is not implemented in gin?

me either,such basic functional route supported by most http server in the world but not in gin
therefore,I have to rewrite the old openapi spec to make path can work with gin

How can i fix this? Where should i start to contribute to fix this?

It's httprouter's problem that gin currently based on

[appcypher]

Wow! Gin routing pattern matching is a mess. Now I have to refactor my app to use another framework.
