Go-OAuth1.0

Golang lightweight package/ implementation example of OAuth1.0 Authentication Header/ Signature calculation (Twitter etc..)

To quickly import the package into your project:

 go get github.com/klaidas/go-oauth1

Example usage:

package main

import (
    "fmt"
    oauth1 "go-oauth1"
    "net/http"
)

func main() {
    method := http.MethodPost
    url := "https://api.twitter.com/1.1/statuses/update.json?include_entities=true"

    auth := oauth1.OAuth1{
        ConsumerKey: "xvz1evFS4wEEPTGEFPHBog",
        ConsumerSecret: "kAcSOqF21Fu85e7zjz7ZN2U4ZRhfV3WpwPAoE3Z7kBw",
        AccessToken: "370773112-GmHxMAgYyLbNEtIKZeRNFsMKPR9EyMZeS9weJAEb",
        AccessSecret: "LswwdoUaIvS8ltyTt5jkRh4J50vUPVVHtR2YPi5kE",
    }

    authHeader := auth.BuildOAuth1Header(method, url, map[string]string {
        "include_entities": "true",
        "status": "Hello Ladies + Gentlemen, a signed OAuth request!",
    })

    req, _ := http.NewRequest(method, url, nil)
    req.Header.Set("Authorization", authHeader)

    if res, err := http.DefaultClient.Do(req); err == nil {
        fmt.Println(res.StatusCode)
    }
}

• Simply import the package
• Create an OAuth1 Object with the information you have (In some cases, AccessSecret will be unknown, this is fine)
• Call BuildOAuth1Header to generate your Authorization Header for the request you're making

Output:

OAuth oauth_consumer_key="xvz1evFS4wEEPTGEFPHBog",oauth_token="370773112-GmHxMAgYyLbNEtIKZeRNFsMKPR9EyMZeS9weJAEb",oauth_signature_method="HMAC-SHA1",oauth_timestamp="1318622958",oauth_nonce="kYjzVBB8Y0ZFabxSWbWovY3uYSQ2pTgmZeNu2VS4cg",oauth_version="1.0",oauth_signature="hCtSmYh%2BiHYCEqBWrE7C7hYmtUk%3D"
