Google oAuth - part 2 - simple test

簡單的測試程式碼 ：

<a href="https://accounts.google.com/o/oauth2/v2/auth?response_type=token&scope=email%20profile&state=%2Fprofile&
redirect_uri=http%3A%2F%2Flocalhost%3A8080%2Fraas%2Ftesting%2FgoogleOAuth2_redirectUri.jsp&
client_id=YOUR_Client_ID">Google login test </a>

YOUR_Client_ID , 記得要修改 , 

如何取得client_id ,請參考前一篇文章  Google oAuth - part 1 

redirect_uri 後面會用到

測試結果如下：

點擊以下“Google login test”,出現以下畫面（如果已經登入過google,否則會先出現登入畫面)

上圖  ,按下允許或按下取消 , 會到 redirect_uri 這個網址的網頁

在 redirect_uri 這個網頁,可以get token ( access_token )

按下取消 : 

1. location:
   http://localhost:8080/raas/testing/googleOAuth2_redirectUri.jsp#error=access_denied&state=google

Validating the token

https://www.googleapis.com/oauth2/v3/tokeninfo?access_token=ＹＯＵＲ＿ＴＯＫＥＮ

得到結果如下：
