Building RESTful Web services with Go

Creating a sample Go application and proxying it

Now, let us create a bare application server in Go with logging:

mkdir -p $GOPATH/src/github.com/narenaryan/basicServervi $GOPATH/src/github.com/narenaryan/basicServer/main.go

This file is a basic Go server to illustrate the proxy server's functioning. Then, we add a configuration to Nginx to proxy port 8000 (Go running port) to HTTP port (80). Now, let us write the code:

package mainimport (    "encoding/json"    "fmt"    "log"    "net/http"    "os"    "time")// Book holds data of a booktype Book struct {    ID int    ISBN string    Author string    PublishedYear string}func main() {    // File open for reading, writing and appending    f, err := os.OpenFile("app.log", os.O_RDWR|os.O_CREATE|os.O_APPEND, 0666) if err != nil ...
