自上周以来我一直禁用Google登录身份验证我试图让oAuth 2.0使用服务帐户。我们希望为我们的内部Web应用程序的用户提供在办公室外设置的机会。
我下载了最新的Google APIs Client Library for PHP。在Google Developer Console中,我为我的应用程序创建了一个新项目,并创建了Service account
个凭据。我还在开发者控制台中启用了API服务:Admin SDK
。
我已授予帐户用户ID访问权限的范围(我认为):
当我使用service-account.php示例并更改详细信息时,我收到带有访问令牌的JSON,但是当我执行CURL请求(与之前相同)以从用户获取电子邮件设置时,发生错误"You are not authorized to access this API."
。
我的代码:
<?php
include_once "templates/base.php";
require_once realpath(dirname(__FILE__) . '/../src/Google/autoload.php');
$client_id = '124331845-DELETEDPART-hbh89pbgl20citf6ko.apps.googleusercontent.com'; //Client ID
$service_account_name = '124331845-DELETEDPART-89pbgl20citf6ko@developer.gserviceaccount.com'; //Email Address
$key_file_location = 'globaltext-4ce09b20cb73.p12'; //key.p12
$client = new Google_Client();
if (isset($_SESSION['service_token'])) {
$client->setAccessToken($_SESSION['service_token']);
}
$key = file_get_contents($key_file_location);
$cred = new Google_Auth_AssertionCredentials(
$service_account_name,
array('https://apps-apis.google.com/a/feeds/emailsettings/2.0/'),
$key
);
$client->setAssertionCredentials($cred);
if ($client->getAuth()->isAccessTokenExpired()) {
$client->getAuth()->refreshTokenWithAssertion($cred);
}
$aOutput = json_decode($client->getAccessToken());
$strEmailAdresSplit = explode('@', "FIRSTNAME.LASTNAME@DOMAIN.EXTENSION");
$strDomein = $strEmailAdresSplit[1];
$strAlias = $strEmailAdresSplit[0];
$resConnectionJobs = curl_init();
$aHeader = array();
$aHeader[] = 'Authorization: Bearer '.$aOutput->access_token;
$aHeader[] = 'Content-Type: application/atom+xml';
curl_setopt($resConnectionJobs, CURLOPT_URL, "https://apps-apis.google.com/a/feeds/emailsettings/2.0/DOMAIN.EXTENSION/FIRSTNAME.LASTNAME/vacation");
curl_setopt($resConnectionJobs, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($resConnectionJobs, CURLOPT_HTTPHEADER, $aHeader);
curl_setopt($resConnectionJobs, CURLOPT_RETURNTRANSFER, true);
curl_setopt($resConnectionJobs, CURLOPT_HEADER, false);
$oCurlData = curl_exec($resConnectionJobs);
curl_close($resConnectionJobs);
echo $oCurlData;
?>

您确定您的凭据是否正常?
请尝试以下程序以确保您拥有正确的凭据。
创建API密钥
转到developer's console并按照以下步骤操作:
获取访问令牌&amp;刷新令牌
创建包含以下代码的文件:
<?php
if (isset($_GET['code'])) {
// try to get an access token
$code = $_GET['code'];
$url = 'https://accounts.google.com/o/oauth2/token';
$params = array(
"code" => $code,
"client_id" => YOUR_CLIENT_ID,
"client_secret" => YOUR_CLIENT_SECRET,
"redirect_uri" => 'http://' . $_SERVER["HTTP_HOST"] . $_SERVER["PHP_SELF"],
"grant_type" => "authorization_code"
);
$ch = curl_init();
curl_setopt($ch, constant("CURLOPT_" . 'URL'), $url);
curl_setopt($ch, constant("CURLOPT_" . 'POST'), true);
curl_setopt($ch, constant("CURLOPT_" . 'POSTFIELDS'), $params);
$output = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
if ($info['http_code'] === 200) {
header('Content-Type: ' . $info['content_type']);
return $output;
} else {
return 'An error happened';
}
} else {
$url = "https://accounts.google.com/o/oauth2/auth";
$params = array(
"response_type" => "code",
"client_id" => YOUR_CLIENT_ID,
"redirect_uri" => 'http://' . $_SERVER["HTTP_HOST"] . $_SERVER["PHP_SELF"],
"scope" => "https://www.googleapis.com/auth/plus.me"
);
$request_to = $url . '?' . http_build_query($params);
header("Location: " . $request_to);
}
现在,将YOUR_CLIENT_ID
和YOUR_CLIENT_SECRET
替换为您的客户端ID和客户端密码。
确保您的范围正确无误。例如,如果您想要访问Google Analytics,则应为https://www.googleapis.com/auth/analytics
。
如果您运行该文件,则应获得OAuth2批准屏幕。
如果您现在按Accept
,您应该得到如下结果:
{
"access_token" : YOUR_ACCESS_TOKEN,
"token_type" : "Bearer",
"expires_in" : 3600,
"refresh_token" : YOUR_REFRESH_TOKEN
}
结果可能包含其他字段,具体取决于您申请的范围。
在后台与Google的系统连接
一旦您完成上述工作,您的应用程序需要实现以下工作流程:
1)检查您的输入是否包含名为&#34;代码&#34;的GET参数。如果&#34;代码&#34;存在,获取新的访问令牌并重复此步骤(刷新页面) 如果&#34;代码&#34;不存在,请转到第2步。
2)检查您是否为您的服务存储了凭据。如果存在凭据,请检查您的访问令牌是否已过期或将很快过期。然后转到步骤3.如果凭据不存在,请转到服务的身份验证路径以获取身份验证代码并返回步骤1(确保Google重定向到您当前的网址)。
3)如果需要刷新,请刷新页面并返回步骤1。 如果不需要刷新,您就可以在第一时间真正做好自己想做的事情了。
但是,如果oAuth2为您流动,Google的PHP库会照顾您。如果您正在使用他们的图书馆,图书馆将负责三步流程中的每个步骤,您应该可以立即为Google的服务做任何您想做的事情。我自己在my Google Adwords dashboard中使用此策略。
但是,您可以编写自定义库并直接连接服务。以下是几个月前我写的一个项目的开发代码。虽然它没有开箱即用(因为它是一个较大的应用程序的控制器),它应该可以帮助您了解Google的图书馆所处理的流程引擎盖。

答案 1 :(得分:-1)
看起来你可能遇到了我遇到的问题。
对Google_Auth_AssertionCredentials
的调用实际上需要的参数多于您发送到服务帐户的参数。 (至少,它确实在我的情况下。)
您需要传递足够的参数来包含sub(由于该用户而采取操作的用户)。
没有它,我总是拒绝访问。这显然不是很明显,因为甚至有一个函数添加到php库loadServiceAccountJson
,它应该设置一个服务帐户客户端连接,但因为它没有&#39而中断; t set sub。
