A Facebook Graph API SDK In Golang

This is a Go library fully supports Facebook Graph API (both 1.0 and 2.0) with file upload, batch request, FQL and multi-FQL. It can be used in Google App Engine.

See full document for details.

Quick Tutorial

Here is a sample to read my Facebook username by uid.

    package main

    import (
        "fmt"
        fb "github.com/huandu/facebook"
    )

    func main() {
        res, _ := fb.Get("/538744468", fb.Params{
            "fields": "username",
        })
        fmt.Println("here is my facebook username:", res["username"])
    }

Type of res["username"] is interface{}. This library provides several helpful methods to decode fields to any Go type or even a custom Go struct.

    // Decode "username" to a go string.
    var username string
    res.DecodeField("username", &username)
    fmt.Println("alternative way to get username:", username)

    // It's also possible to decode the whole result into a predefined struct.
    type User struct {
        Username string
    }
    var user User
    res.Decode(&user)
    fmt.Println("print username in struct:", user.Username)

Out of Scope

1. No OAuth integration. This library only provides APIs to parse/verify access token and OAuth code.
2. No old RESTful API support. Such APIs are deprecated for years. Forget about them.
