Question

我正在尝试使用Gmail API和php更新标签。

我已经回顾了问题here，但这是关于python的，对我来说没有多大意义。

我指的是代码here。

具体来说，这个：

    /**
 * Update an existing Label.
 *
 * @param  Google_Service_Gmail $service Authorized Gmail API instance.
 * @param  string $userId User's email address. The special value 'me'
 * can be used to indicate the authenticated user.
 * @param  string $labelId ID of Label to update.
 * @param  string $labelName Updated name.
 * @param  string $labelListVisibility Updated Label list visibility.
 * @param  string $messageListVisibility Updated Message list visibility.
 * @return Google_Service_Gmail_Label updated Label.
 */
function updateLabel($service, $userId, $labelId, $labelName,
  $labelListVisibility, $messageListVisibility) {
  $label = new Google_Service_Gmail_Label();
  $label->setName($labelName);
  $label->setLabelListVisibility($labelListVisibility);
  $label->setMessageListVisibility($messageListVisibility);
  try {
    $label = $service->users_labels->update($userId, $labelId, $label);
    print 'Label with ID: ' . $labelId . ' successfully updated.';
  } catch (Exception $e) {
    print 'An error occurred: ' . $e->getMessage();
  }
  return $label;
}

我想我已经找到了所有的参数，但它说的是，

* @param  Google_Service_Gmail $service Authorized Gmail API instance.

我不知道“授权的Gmail API实例”指的是什么。

我已经使用API连接并验证了（我可以列出标签），所以我猜它正在寻找我的连接的一些参考。但我不知道在哪里可以找到它或如何表达它。

以下代码用于列出标签（gauth.php）：

    <?php
session_start();

require_once('settings.php');
require_once('google-login-api.php');

// Google passes a parameter 'code' in the Redirect Url
if(isset($_GET['code'])) {
    try {
        $gapi = new GoogleLoginApi();

        // Get the access token 
        $data = $gapi->GetAccessToken(CLIENT_ID, CLIENT_REDIRECT_URL, CLIENT_SECRET, $_GET['code']);

        // Get user information
        $user_labels = $gapi->ListUserLabels($data['access_token']);

        $labels_array = $user_labels["labels"];

        $i = 0;

        while($i <= count($labels_array)) 
            {
            if($labels_array[$i]['type'] == "user")
                {
                echo $labels_array[$i]['name']." - ".$labels_array[$i]['id'];
                echo'<br />';
                }
            $i++;
            } 


        // Now that the user is logged in you may want to start some session variables
        $_SESSION['logged_in'] = 1;

        // You may now want to redirect the user to the home page of your website
        // header('Location: home.php');
    }
    catch(Exception $e) {
        echo $e->getMessage();
        exit();
    }
}

这是google-login-api.php：

class GoogleLoginApi
{
    public function GetAccessToken($client_id, $redirect_uri, $client_secret, $code) {  
        $url = 'https://accounts.google.com/o/oauth2/token';            

        $curlPost = 'client_id=' . $client_id . '&redirect_uri=' . $redirect_uri . '&client_secret=' . $client_secret . '&code='. $code . '&grant_type=authorization_code';
        $ch = curl_init();      
        curl_setopt($ch, CURLOPT_URL, $url);        
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);        
        curl_setopt($ch, CURLOPT_POST, 1);      
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);    
        $data = json_decode(curl_exec($ch), true);
        $http_code = curl_getinfo($ch,CURLINFO_HTTP_CODE);      
        if($http_code != 200) 
            throw new Exception('Error : Failed to receieve access token');

        return $data;
    }

    public function ListUserLabels($access_token) { 
        //$url = 'https://www.googleapis.com/plus/v1/people/me';    
        $url = 'https://www.googleapis.com/gmail/v1/users/me/labels';       

        $ch = curl_init();      
        curl_setopt($ch, CURLOPT_URL, $url);        
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: Bearer '. $access_token));
        $data = json_decode(curl_exec($ch), true);
        $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);     
        if($http_code != 200) 
            throw new Exception('Error : Failed to get user information');

        return $data;
    }
}

和settings.php：

/* Google App Client Id */
define('CLIENT_ID', 'xxxxxxxxxxxxxxxx.apps.googleusercontent.com');

/* Google App Client Secret */
define('CLIENT_SECRET', 'xxxxxxxxxxxxxxxxxxx');

/* Google App Redirect Url */
define('CLIENT_REDIRECT_URL', 'http://localhost:8888/xxxxxxxx/gauth/gauth.php');

感谢。

这也把我绊倒了！如今，Google似乎并不在乎PHP，是吧？他们的文档确实像人们所说的那样糟糕。

$gmail = new Google_Service_Gmail($client);

这就是我为克服这一障碍而取得进步的方法。我认为的含义是，您必须像上面那样创建一个特定的服务对象，而不仅仅是使用客户端对象本身？可以用更好的措辞来表达，或者加以扩展。

祝你好运！（您将需要它！）

要每次获取访问令牌，只需使用有效的凭据调用此函数

function GetRefreshedAccessToken($client_id, $refresh_token, $client_secret) {  

    $url_token = 'https://www.googleapis.com/oauth2/v4/token';          

    $curlPost = 'client_id=' . $client_id . '&client_secret=' . $client_secret . '&refresh_token='. $refresh_token . '&grant_type=refresh_token';
    $ch = curl_init();      
    curl_setopt($ch, CURLOPT_URL, $url_token);      
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);        
    curl_setopt($ch, CURLOPT_POST, 1);      
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);    
    $data = json_decode(curl_exec($ch), true);  //print_r($data);
    $http_code = curl_getinfo($ch,CURLINFO_HTTP_CODE);  

    if($http_code != 200) 
        throw new Exception('Error : Failed to refresh access token');

    return $data;
}
