# Gopher protocol library for Golang
|
||||
|
||||
This is a standards compliant Gopher library for the Go programming language
|
||||
implementing the RFC 1436 specification. The library includes both client and
|
||||
server handling and examples of each.
|
||||
|
||||
## Installation
|
||||
|
||||
$ go get github.com/prologic/go-gopher
|
||||
|
||||
## Usage
|
||||
|
||||
```#!go
|
||||
import "github.com/prologic/go-gopher"
|
||||
```
|
||||
|
||||
## Example
|
||||
|
||||
### Client
|
||||
|
||||
```#!go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
|
||||
"github.com/prologic/go-gopher"
|
||||
)
|
||||
|
||||
func main() {
|
||||
res, _ := gopher.Get("gopher://gopher.floodgap.com/")
|
||||
bytes, _ = res.Dir.ToText()
|
||||
fmt.Println(string(bytes))
|
||||
}
|
||||
```
|
||||
|
||||
### Server
|
||||
|
||||
```#!go
|
||||
package main
|
||||
|
||||
import (
|
||||
"log"
|
||||
|
||||
"github.com/prologic/go-gopher"
|
||||
)
|
||||
|
||||
func hello(w gopher.ResponseWriter, r *gopher.Request) {
|
||||
w.WriteInfo("Hello World!")
|
||||
}
|
||||
|
||||
func main() {
|
||||
gopher.HandleFunc("/hello", hello)
|
||||
log.Fatal(gopher.ListenAndServe("localhost:70", nil))
|
||||
}
|
||||
