Angular并在heroku上运行

Question

I am trying to put my app on Heroku. I am using angular on the front-end and Go on the backend.

I followed this tutorial http://mmcgrana.github.io/2012/09/getting-started-with-go-on-heroku.html

However, when I go to the domain of my heroku app, I get the directory of my app (everything in the git). When I navigate to the /app folder, (where my angular app lives) it shows the app.

I don't want my app to be at

foobar.herokuapp.com/app/#/

I want it to be at

foobar.herokuapp.com

A simplified version of my app directory is:

foobar
 - /app
 - /server/server.go
 - .godir             // contains "app"
 - Procfile           // contains "web: server"

I ran "go get" from inside my /server folder

These work:

$ PORT=5000 demoapp

$ curl -i http://127.0.0.1:5000/

Here is my simple server.go

package main

import (
"github.com/gorilla/handlers"
"log"
"net/http"
"os"
)

func main() {
log.Println("Starting Server")
http.Handle("/", logHandler(http.FileServer(http.Dir("../app/"))))

log.Println("Listening...")
panic(http.ListenAndServe(":"+os.Getenv("PORT"), nil))
}

func logHandler(h http.Handler) http.Handler {
return handlers.LoggingHandler(os.Stdout, h)

}

Answer 1

Changing your FileServer directory from "../app/" to "app/" (relative) or "/app/app/" (absolute) should solve the issue.

http.Handle("/", logHandler(http.FileServer(http.Dir("app/"))))

Your project root is the work folder when Heroku executes the Procfile command. It has the absolute path /app which is why ../app brings you back to your project root.

Although your server.go is stored in the ./server subfolder it is still compiled into the project root with package main.
