Iterate through all PostForm values Gin Gonic

Question

Is there an easy way to list / iterate through all post values using Gin Gonic? (Go)

I have tried:

c.Request.ParseForm()
for key, value := range c.Request.PostForm {
    log.Printf("POST %v = %v",key,value)
}

But this shows no values, however when I test the values directly from context:

log.Printf("POST email = %v", c.PostForm("email")

It outputs fine.

What I'm trying to do is to map all post values into a gin.H{} context, so that upon failure I can pass the posted values back into the .HTML template context and have them prefilled (along with my error message). Best I've found is manually wiring each POST value to the gin.H{} map, but for a large form these seems verbose and not ideal.

Answer 1

We also needed something like @BadPirate describes so if anyone need for gin 1.6.2

func register(c *gin.Context){
    c.MultipartForm()
    for key, value := range c.Request.PostForm {
        log.Printf("%v = %v \n",key,value)
    }
}

Thanks @BadPirate and @phoet for the info.
