Reading QueryArray from Gin golang

Question

Hi I am passing a query parameter to my gin server like this:

curl -X POST \
'http://localhost:4000/url?X=val1&Y=val2&x[]=1&x[]=2'

This is then sent to the my gin handler function

func handler (c *gin.Context) {
    fmt.Println(c.Query("X"))
    fmt.Println(c.Query("Y"))
    fmt.Println(c.QueryArray("x"))
}

While c.Query("x") and c.Query("Y") works, c.QueryArray("x") does not work!

I am not sure what am I missing over here. I have tried the same with GET request as well and it does not work.

Other experiments that did not work for me are here:

fmt.Println(c.Params.Get("x"))
fmt.Println(c.Params.Get("gene"))
fmt.Println(c.PostFormArray("x"))

Drafted answer from my comment for SO users.

Repeat field name with values:

curl -X POST 'http://localhost:4000/url?X=val1&Y=val2&x=1&x=2'

or:

Separated by commas:

curl -X POST 'http://localhost:4000/url?X=val1&Y=val2&x=1,2'
