如何使用Google API客户端刷新令牌？

提问于
浏览 次

我一直在使用Google AnalyticsAPI（V3）并遇到了som错误 . 首先，一切都设置正确，并与我的测试帐户一起使用 . 但是，当我想从其他 Profiles ID（相同的Google Accont / GA帐户）中获取数据时，我收到403错误 . 奇怪的是，来自某些GA帐户的数据将返回数据，而其他帐户会生成此错误 .

我已经撤销了令牌并再次进行了身份验证，现在看来我可以从我的所有帐户中获取数据 . 问题解决了？不 . 由于访问密钥将过期，我将再次遇到同样的问题 .

如果我理解正确，可以使用resfreshToken来获取新的authenticationTooken .

问题是，当我跑：

$client->refreshToken(refresh_token_key)

返回以下错误：

Error refreshing the OAuth2 token, message: '{ "error" : "invalid_grant" }'

我检查了refreshToken方法背后的代码，并将请求追溯回“apiOAuth2.php”文件 . 所有参数都正确发送 . grant_type在方法中被硬编码为'refresh_token'，所以我很难理解什么是错的 . 参数数组如下所示：

Array ( [client_id] => *******-uqgau8uo1l96bd09eurdub26c9ftr2io.apps.googleusercontent.com [client_secret] => ******** [refresh_token] => 1\/lov250YQTMCC9LRQbE6yMv-FiX_Offo79UXimV8kvwY [grant_type] => refresh_token )

程序如下 .

$client = new apiClient();
$client->setClientId($config['oauth2_client_id']);
$client->setClientSecret($config['oauth2_client_secret']);
$client->setRedirectUri($config['oauth2_redirect_uri']);
$client->setScopes('https://www.googleapis.com/auth/analytics.readonly');
$client->setState('offline');

$client->setAccessToken($config['token']); // The access JSON object.

$client->refreshToken($config['refreshToken']); // Will return error here

这是一个错误，还是我完全误解了什么？

    所以我终于想出了如何做到这一点 . 基本的想法是，您有第一次请求身份验证时获得的令牌 . 该第一个令牌具有刷新令牌 . 第一个原始令牌在一小时后到期 . 一小时后，您必须使用第一个令牌中的刷新令牌来获取新的可用令牌 . 您使用 $client->refreshToken($refreshToken) 来检索新令牌 . 我将调用此"temp token."您还需要存储此临时令牌，因为一小时后它也会过期并注意它没有与之关联的刷新令牌 . 为了获得新的临时令牌，您需要使用之前使用的方法并使用第一个令牌的refreshtoken . 我在下面附上了代码，这是丑陋的，但我是新的...

    //pull token from database
$tokenquery="SELECT * FROM token WHERE type='original'";
$tokenresult = mysqli_query($cxn,$tokenquery);
if($tokenresult!=0)
{
    $tokenrow=mysqli_fetch_array($tokenresult);
    extract($tokenrow);
}
$time_created = json_decode($token)->created;
$t=time();
$timediff=$t-$time_created;
echo $timediff."<br>";
$refreshToken= json_decode($token)->refresh_token;


//start google client note:
$client = new Google_Client();
$client->setApplicationName('');
$client->setScopes(array());
$client->setClientId('');
$client->setClientSecret('');
$client->setRedirectUri('');
$client->setAccessType('offline');
$client->setDeveloperKey('');

//resets token if expired
if(($timediff>3600)&&($token!=''))
{
    echo $refreshToken."</br>";
    $refreshquery="SELECT * FROM token WHERE type='refresh'";
    $refreshresult = mysqli_query($cxn,$refreshquery);
    //if a refresh token is in there...
    if($refreshresult!=0)
    {
        $refreshrow=mysqli_fetch_array($refreshresult);
        extract($refreshrow);
        $refresh_created = json_decode($token)->created;
        $refreshtimediff=$t-$refresh_created;
        echo "Refresh Time Diff: ".$refreshtimediff."</br>";
        //if refresh token is expired
        if($refreshtimediff>3600)
        {
            $client->refreshToken($refreshToken);
        $newtoken=$client->getAccessToken();
        echo $newtoken."</br>";
        $tokenupdate="UPDATE token SET token='$newtoken' WHERE type='refresh'";
        mysqli_query($cxn,$tokenupdate);
        $token=$newtoken;
        echo "refreshed again";
        }
        //if the refresh token hasn't expired, set token as the refresh token
        else
        {
        $client->setAccessToken($token);
           echo "use refreshed token but not time yet";
        }
    }
    //if a refresh token isn't in there...
    else
    {
        $client->refreshToken($refreshToken);
        $newtoken=$client->getAccessToken();
        echo $newtoken."</br>";
        $tokenupdate="INSERT INTO token (type,token) VALUES ('refresh','$newtoken')";
        mysqli_query($cxn,$tokenupdate);
        $token=$newtoken;
        echo "refreshed for first time";
    }      
}

//if token is still good.
if(($timediff<3600)&&($token!=''))
{
    $client->setAccessToken($token);
}

$service = new Google_DfareportingService($client);

    问题出在刷新令牌中：

    [refresh_token] => 1\/lov250YQTMCC9LRQbE6yMv-FiX_Offo79UXimV8kvwY

    当 '/' 的字符串获得 json encoded 时，它会被 '\' 转义，因此您需要将其删除 .

    您的案例中的刷新令牌应为：

    1/lov250YQTMCC9LRQbE6yMv-FiX_Offo79UXimV8kvwY

    我_2710555已完成的是你已经打印了谷歌发回的json字符串并将其复制并粘贴到你的代码中，因为如果你 json_decode 那么它会正确地为你删除 '\' ！

    访问类型应设置为 offline . state 是您为自己使用而设置的变量，而不是API的用途 .

    确保你有latest version of the client library并添加：

    $client->setAccessType('offline');

    有关参数的说明，请参见Forming the URL .

    这是设置令牌的片段，在此之前确保访问类型应设置为 offline

    if (isset($_GET['code'])) {
  $client->authenticate();
  $_SESSION['access_token'] = $client->getAccessToken();
}

    刷新令牌

    $google_token= json_decode($_SESSION['access_token']);
$client->refreshToken($google_token->refresh_token);

    这将刷新你的令牌，你必须在会话中更新它，你可以做

    $_SESSION['access_token']= $client->getAccessToken()

    @ uri-weg发布的答案对我有用，但由于我没有发现他的解释非常清楚，让我稍微改写一下 .

    在第一个访问权限序列期间，在回调中，当您到达收到身份验证代码的位置时，您也必须 save the access token and the refresh token .

    原因是google api仅在提示访问权限时才向您发送带有刷新令牌的访问令牌 . 下一个访问令牌将在没有任何刷新令牌的情况下发送（除非您使用 approval_prompt=force 选项） .

    The refresh token you received the first time stays valid until the user revokes access permission.

    在简单的php中，回调序列的一个例子是：

    // init client
// ...

$authCode = $_GET['code'];
$accessToken = $client->authenticate($authCode);
// $accessToken needs to be serialized as json
$this->saveAccessToken(json_encode($accessToken));
$this->saveRefreshToken($accessToken['refresh_token']);

    稍后，在简单的php中，连接序列将是：

    // init client
// ...

$accessToken = $this->loadAccessToken();
// setAccessToken() expects json
$client->setAccessToken($accessToken);

if ($client->isAccessTokenExpired()) {
    // reuse the same refresh token
    $client->refreshToken($this->loadRefreshToken());
    // save the new access token (which comes without any refresh token)
    $this->saveAccessToken($client->getAccessToken());
}

    这是我在我的项目中使用的代码，它工作正常：

    public function getClient(){
    $client = new Google_Client();
    $client->setApplicationName(APPNAME);       // app name
    $client->setClientId(CLIENTID);             // client id
    $client->setClientSecret(CLIENTSECRET);     // client secret 
    $client->setRedirectUri(REDIRECT_URI);      // redirect uri
    $client->setApprovalPrompt('auto');

    $client->setAccessType('offline');         // generates refresh token

    $token = $_COOKIE['ACCESSTOKEN'];          // fetch from cookie

    // if token is present in cookie
    if($token){
        // use the same token
        $client->setAccessToken($token);
    }

    // this line gets the new token if the cookie token was not present
    // otherwise, the same cookie token
    $token = $client->getAccessToken();

    if($client->isAccessTokenExpired()){  // if token expired
        $refreshToken = json_decode($token)->refresh_token;

        // refresh the token
        $client->refreshToken($refreshToken);
    }

    return $client;
}

    有同样的问题;我的剧本昨天有效，因为一些奇怪的原因今天没有 . 没有变化 .

    显然这是因为我的系统时钟关闭了2.5（!!）秒，与NTP同步修复了它 .

    仅供参考：如果您在过期时拥有刷新令牌，3.0 Google AnalyticsAPI将自动刷新访问令牌，因此您的脚本永远不需要 refreshToken .

    （参见 auth/apiOAuth2.php 中的 Sign 函数）

    有时刷新令牌我不是通过使用 $client->setAccessType ("offline"); 生成的 .

    试试这个：

    $client->setAccessType ("offline");
$client->setApprovalPrompt ("force");

    我使用智能代码的示例和当前版本的Google API，但那个没有用 . 我认为他的API太过时了 .

    所以，我刚刚根据其中一个API示例编写了我自己的版本...它输出访问令牌，请求令牌，令牌类型，ID令牌，到期时间和创建时间为字符串

    如果您的客户端凭据和开发人员密钥是正确的，则此代码应该是开箱即用的 .

    <?php

session_start();

$client = new Google_Client();
$client->setApplicationName("Get Token");
// Visit https://code.google.com/apis/console?api=plus to generate your
// oauth2_client_id, oauth2_client_secret, and to register your oauth2_redirect_uri.
$oauth2 = new Google_Oauth2Service($client);

if (isset($_GET['code'])) {
    $client->authenticate($_GET['code']);
    $_SESSION['token'] = $client->getAccessToken();
    $redirect = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];
    header('Location: ' . filter_var($redirect, FILTER_SANITIZE_URL));
    return;
}

if (isset($_SESSION['token'])) {
    $client->setAccessToken($_SESSION['token']);
}

if (isset($_REQUEST['logout'])) {
    unset($_SESSION['token']);
    $client->revokeToken();
}

    我有一个相同的问题与谷歌/谷歌api-php-client v2.0.0-RC7和搜索1小时后，我解决这个问题使用 json_encode 像这样：

    if ($client->isAccessTokenExpired()) {
        $newToken = json_decode(json_encode($client->getAccessToken()));
        $client->refreshToken($newToken->refresh_token);
        file_put_contents(storage_path('app/client_id.txt'), json_encode($client->getAccessToken()));
    }

    根据Authentication on google: OAuth2 keeps returning 'invalid_grant'

    “您应该重用第一次成功验证后获得的访问令牌 . 如果您之前的令牌尚未过期，您将收到invalid_grant错误 . 请将其缓存到某处，以便您可以重复使用它 . ”
