help getting started with goji

[theirf]

Apologies if I am being a noob / novice, but I am just getting started with Go.

I'm trying to run the sample programme and I am getting an error.

Here is the contents of hello.go:

package main

import (
        "fmt"
        "net/http"

        "github.com/zenazn/goji"
        "github.com/zenazn/goji/web"
)

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

func main() {
        goji.Get("/hello/:name", hello)
        goji.Serve()
}

hello.go:7:9: cannot find package "github.com/zenazn/goji" in any of:
/usr/local/go/src/pkg/github.com/zenazn/goji (from $GOROOT)
/Users/Irfan/Projects/Go/src/github.com/zenazn/goji (from $GOPATH)
hello.go:8:9: cannot find package "github.com/zenazn/goji/web" in any of:
/usr/local/go/src/pkg/github.com/zenazn/goji/web (from $GOROOT)
/Users/Irfan/Projects/Go/src/github.com/zenazn/goji/web (from $GOPATH)

What am I doing wrong?

Did you run go get github.com/zenazn/goji?

[theirf]

Oh, no I didn't!

I'm so sorry. I was too excited about Goji.

Wait, I ran it. Now it is running successfully, saying Starting Goji on
[::]:8000 in the terminal, but that's it. I go to localhost:8000 and
nothing is there.

Because you are specifying in your routes that goji is to match requests on the following URL:

goji.Get("/hello/:name", hello)

You would want to specify that url in your browser. So for your example:

http://localhost:8000/hello/theirf

oh, beautiful! What I'd like to do is have a form and then on submit, sends what is in the textField to go and then print hello, name on the confirmation page.

Can someone help me with that?

@theirf it's not an issue related to goji code and project.

[theirf]

True, but I figured the best place to get help with how to use goji would
be here.

@theirf — for my own sanity, I'd actually like to keep the issues page on Github focused on issues with Goji itself. I'll look into starting a mailing list or IRC channel some time this weekend.

As for your original question, this can be accomplished using an HTML form with an "action" attribute (https://developer.mozilla.org/en-US/docs/Web/HTML/Element/form) that POSTs to another route on your site. You can then dig the form data from Go's http.Request object. There are many tutorials online covering POSTing data, and while I doubt any will be Goji-specific, I'm sure you'll find that the principles and ideas—as well as all of the HTML—translate well.
