[SOLVED] Gin Gonic - Literal colon inside the URL

Gin Gonic - Literal colon inside the URL

I'm creating some REST API with Gin Gonic in go. I have to expose this endpoint with this URL: /api/v1/action::request::export I'm using gin gonic to create the routes and I got this error "only one wildcard per path segment is allowed" because the colon ":" is used to map a parameters in the URL.

There is a way to escape the ":" character and use it into the URL?

Thanks

Solution

Like F.S mentioned in comment, you could use just one pathParam action and then in code handle parsing as needed.

Here is an example that would work for you:

package main

import (
    "strings"
    "github.com/gin-gonic/gin"
)

func main() {
    r := gin.Default()
    r.GET("/api/v1/:action", func(c *gin.Context) {
        params, ok := c.Params.Get("action")
        if !ok {
            // handle error
        }

        eachParam := strings.SplitN(params, ":", 3)
        request, export := eachParam[1], eachParam[2] // your actual params divided by ":"

        c.JSON(200, gin.H{
            "message": "good",
        })
    })
    r.Run()
}

But of course, this approach have its own caveats, you have to handle exceptions and edge cases yourself.
