我們平常也經常使用QQ，微信賬號，登錄其他應用。最近公司讓我給網站添加一個谷歌賬號登錄。我來這里記錄一下，莫怪~~~莫怪~~~
1. 申請一個賬號登錄ID: https://developers.google.com/identity/sign-in/web/sign-in#before_you_begin
2. 拿到ID:
var clientId = "**********.apps.googleusercontent.com";
3. 在官網https://developers.google.com/identity/sign-in/web/有一段代碼更改下clientId就可以在頁面中使用，只是效果可能與實際需求有點差別。
<html lang="en"> <head> <title>test.html</title> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta name="google-signin-scope" content="profile email"> <meta name="google-signin-client_id" content="*** Your client_id ***.apps.googleusercontent.com" /> <script type="text/javascript" src="../js/jquery-1.8.3.min.js"></script> <script src="https://apis.google.com/js/platform.js" async defer></script> <script type="text/javascript"> function onSignIn(googleUser) { var profile = googleUser.getBasicProfile(); var parameter = { id: profile.getId(), userName: profile.getName(), email: profile.getEmail(), imageUrl: profile.getImageUrl(), givenName: profile.getGivenName(), familyName: profile.getFamilyName(), imgUrl: profile.getImageUrl() };
var vid_token = googleUser.getAuthResponse().id_token; } function signOut() { var auth2 = gapi.auth2.getAuthInstance(); auth2.signOut().then(function () { console.log('User signed out.'); }); }</script> </head> <body> <div class="g-signin2" data-onsuccess="onSignIn" data-theme="dark"></div> <a href="#" onclick="signOut();">Sign out</a> </body> </html>
4. 來啦來啦，下面是我根據公司網站和實際需求，參考着官網上寫的代碼。（感覺公司對待某些網站功能時，挺隨意的，需要的說添加就添加。呃，我啥也沒說~_~~~）

5.API: https://oauth2.googleapis.com/tokeninfo?id_token=*********驗證通過的返回值

6. 在瀏覽器加載頁面時，判斷是否登錄google賬號，若已登錄，則彈出提示窗口。
這個功能在iframe嵌套的頁面會出錯，具體原因不知道，聽老大說，有些服務會禁止在iframe嵌套的頁面使用。
