Issue
My code
app.Get("/event/*", func(c *fiber.Ctx) error {
// GET THE ACCOUNT FROM THE PATH
fmt.Println("PATH")
fmt.Println(c.Path())
fmt.Println("END PATH")
fmt.Printf("%+v\n", c)
fmt.Println("END PERCENT V")
msg := fmt.Sprintf("%s\n", c.Params("*"))
fmt.Println(msg)
fmt.Println("END PARAMS *")
fmt.Println(c.Body())
fmt.Println("END BODY")
fmt.Println(c)
fmt.Println("END RAW")
I call this
curl 'localhost:3000/event/?a=b&b=c&d=e'
My output
PATH
/event/
END PATH
#0000000100000001 - 127.0.0.1:3000 <-> 127.0.0.1:46890 - GET http://localhost:3000/event/?a=b&b=c&d=e
END PERCENT V
END PARAMS *
[]
END BODY
#0000000100000001 - 127.0.0.1:3000 <-> 127.0.0.1:46890 - GET http://localhost:3000/event/?a=b&b=c&d=e
END RAW
What I want is
a=b&b=x&d=e as a string or as a json object. However! There is no fixed format to this string. it could just as easily be blah=123&blah2=234. or x=1&somekey=somevalue
All the docs i can find involve turning the querystring into a struct. All this service needs to do is convert the query string to json and write it to disk. If I drop the ?, I can use Params(‘*’) to get it, but then the path is problematic, because I need the word "/event/" also. And that value is also arbitrary. This service just writes it to disk and return 200.
But I cannot figure out how to get the query string using golang’s Fiber. Is there a way? If not, is there some other performant method of getting this?
Solution
fiber uses fasthttp.
- https://pkg.go.dev/github.com/gofiber/fiber/v2#Request
- https://pkg.go.dev/github.com/valyala/fasthttp#RequestCtx.URI
package main
import (
"fmt"
"log"
"github.com/gofiber/fiber/v2"
)
func main() {
app := fiber.New()
app.Get("/", func (c *fiber.Ctx) error {
fmt.Println(string(c.Request().URI().QueryString()))
return c.SendString("Hello, World!")
})
log.Fatal(app.Listen(":3000"))
}
