Parse input from HTML <form>

Question

I got something running with the Goji framework:

package main

import (
        \"fmt\"
        \"net/http\"

        \"github.com/zenazn/goji\"
        \"gi         


        

Answer 1

In order to read html form values you have to first call r.ParseForm(). The you can get at the form values.

So this code:

func hello(c web.C, w http.ResponseWriter, r *http.Request){
    name := r.PostFormValue("name")
    fmt.Fprintf(w, "Hello, %s!", name)
}

Should be this:

func hello(c web.C, w http.ResponseWriter, r *http.Request){

    //Call to ParseForm makes form fields available.
    err := r.ParseForm()
    if err != nil {
        // Handle error here via logging and then return            
    }

    name := r.PostFormValue("name")
    fmt.Fprintf(w, "Hello, %s!", name)
}

Edit: I should note that this was a point that tripped me up when learning the net/http package
