網站用戶與他們的Gmail帳戶永久連接如果用戶允許訪問他們的數據

Question

我探索谷歌日曆API以同步用戶谷歌事件與我的網站events.First我完成與gmail登錄並獲得用戶帳戶離線的權限訪問。我的代碼是

<?php 
 
require_once __DIR__.'/vendor/autoload.php'; 
 

 
session_start(); 
 

 
$client = new Google_Client(); 
 
$client->setAuthConfigFile(__DIR__.'/client_secrets.json'); 
 
$client->setRedirectUri('http://' . $_SERVER['HTTP_HOST'] . '/google4/oauth2callback.php'); 
 
$client->addScope(Google_Service_Calendar::CALENDAR_READONLY); 
 
$client->setAccessType('offline'); 
 
$client->setApprovalPrompt('force'); 
 
$client->setIncludeGrantedScopes(true); 
 
//echo $_GET['access_token'].' '.$_GET['code']; 
 
if (!isset($_GET['code']) && !isset($_SESSION['access_token'])) { //echo "werwe";exit; 
 
    $auth_url = $client->createAuthUrl(); 
 
    header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL)); 
 
} else { 
 
    $db = mysql_connect('localhost','root',''); 
 
    mysql_select_db('google',$db); 
 
    //echo $_SESSION['refresh_token']; 
 
    $client->refreshToken($_SESSION['refresh_token']); 
 
    $client->authenticate($_GET['code']); 
 
    // $client()->getRefreshToken(); 
 
    $_SESSION['access_token'] = $client->getAccessToken(); 
 
    //print_r($_SESSION['access_token']);exit; 
 
    // 
 
    $sql = "update google set access_token='".$_SESSION['access_token']['refresh_token']."' WHERE userId = '".$_SESSION['userId']."'"; 
 
    mysql_query($sql); 
 
    $_SESSION['refresh_token']=$_SESSION['access_token']['refresh_token']; 
 
    $redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . '/google4'; 
 
    header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL)); 
 
} 
 
?>

當用戶允許從API訪問他們的數據谷歌返回類似

[ 
    access_token => xxx, 
    token_type => bearer, 
    created => xxx, 
    expires_in => 3600, 
    refresh_token => xxx 
] 

陣列使用此訪問令牌我得到的事件數據，我的代碼是

<?php 
 
require_once __DIR__.'/vendor/autoload.php'; 
 
//error_reporting(E_PARSE); 
 
session_start(); 
 

 
$client = new Google_Client(); 
 
$client->setAuthConfig(__DIR__.'/client_secrets.json'); 
 
$client->addScope(Google_Service_Drive::DRIVE_METADATA_READONLY); 
 
$client->setRedirectUri('http://' . $_SERVER['HTTP_HOST'] . '/google4/oauth2callback.php'); 
 
$client->setAccessType('offline'); 
 
echo "<a href='logout.php'> logout </a>"; 
 

 
if (isset($_SESSION['access_token']) &&   $_SESSION['refresh_token']) { 
 
    $client->refreshToken($_SESSION['refresh_token']); 
 
    $client->setAccessToken($_SESSION['access_token']); 
 
    $service = new Google_Service_Calendar($client); 
 

 
    $calendarId = 'primary'; 
 
    $optParams = array(
 
     'maxResults' => 10, 
 
     'orderBy' => 'startTime', 
 
     'singleEvents' => TRUE, 
 
     'timeMin' => date('c'), 
 
    ); 
 
$results = $service->events->listEvents($calendarId, $optParams); 
 

 
    if (count($results->getItems()) == 0) { 
 
    print "No upcoming events found.\n"; 
 
    } else { 
 
    print "Upcoming events:\n"; 
 
    foreach ($results->getItems() as $event) { 
 
    $start = $event->start->dateTime; 
 
    if (empty($start)) { 
 
     $start = $event->start->date; 
 
    } 
 
    printf("%s (%s)\n", $event->getSummary(), $start); 
 
    } 
 
} 
 

 
} else { 
 
    $redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . '/google4/oauth2callback.php'; 
 
    header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL)); 
 
}

我得到事件數據但會話過期時如何獲取用戶數據？

我有什麼來存儲用戶，從而使該網站直接連接到他們的帳戶，如果我有脫機訪問權限我可以訪問用戶的日曆數據下線？

如果會話過期使用保存的用戶數據，每次我如何從用戶日曆中獲取數據？

Answer 1

谷歌允許脫機訪問60天（請確保google.com目前的政策） 要離線訪問功能，你需要通過你的OAuth請求以下標誌

access_type=offline 

請注意以下標誌是，當有用你要問離線訪問用戶強行

approval_prompt=force 

所以，每次你需要獲得你需要請求與以前的訪問令牌數據刷新令牌訪問谷歌的數據。您必須將訪問令牌數據保存到數據庫中。
