Print HTTP request to stdout

echo.go

package main

import (
    "net"
    "os"
    "log"
    "fmt"
    "io"
)

func main() {
    port := 8080
    ln, err := net.Listen("tcp", fmt.Sprintf(":%d", port))
    if err != nil {
        log.Fatalf("could not listen to tcp connections on port %d: %v", port, err)
    }
    for {
        conn, err := ln.Accept()
        if err != nil {
            log.Printf("could not accept connection: %v", err)
        }
        go func(){
            io.Copy(os.Stdout, conn)
        }()
    }
}

For debugging purposes it is useful to see the request that gets sent.

eg. I was trying to send this request and it was failing because # isn't allowed in JSON in PyCharm. When I fired the request to the echo.go server above I could see why.

POST http://localhost:8080/
Content-Type: application/json

{
    "email": "foo.bar@example.com",
    "password": "pass#word"
}

This is what was sent

POST / HTTP/1.1
Content-Type: application/json
Content-Length: 60
Host: localhost:8080
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.5.2 (Java/1.8.0_152-release)
Accept-Encoding: gzip,deflate

{
    "email": "foo.bar@example.com",
    "password": "pass}
