What's the easiest way to authenticate using JWT in Gol?

<p>I&#39;m newbie to go and developed a REST API in Go withouth framework. Now I want to use Google OAuth2 authentication. I&#39;m wondering what is the most fool-proff way to do so? </p> <hr/>**评论：**<br/><br/>shovelpost: <pre><blockquote> <p>Now I want to use Google OAuth2 authentication.</p> </blockquote> <p>Use <a href="https://godoc.org/golang.org/x/oauth2" rel="nofollow">golang.org/x/oauth2</a>.</p></pre>gar44: <pre><p>Any slow-paced tutorial to use the library? </p></pre>icholy: <pre><p>see <a href="https://godoc.org/golang.org/x/oauth2#example-Config" rel="nofollow">https://godoc.org/golang.org/x/oauth2#example-Config</a></p></pre>gar44: <pre><p>Too cryptic for me. </p></pre>gogroob: <pre><p>Full tutorial from start to finish <a href="https://cloud.google.com/go/getting-started/authenticate-users" rel="nofollow">https://cloud.google.com/go/getting-started/authenticate-users</a></p></pre>gar44: <pre><p>This is for GAE, not useful for me. </p></pre>dobegor: <pre><p>No it&#39;s not for GAE only.
