由于 Google 登录身份验证自上周起被禁用,我正在尝试让 oAuth 2.0 使用服务帐户。我们希望为我们内部网络应用程序的用户提供设置外出的机会。

我下载了最新的Google APIs Client Library for PHP .在Google Developer Console ,我为我的应用程序创建了一个新项目并创建了一个 Service account 凭据。我还在开发者控制台中启用了 API 服务:Admin SDK

enter image description here

我已授予帐户用户 ID 访问正确范围的权限(我认为): enter image description here

当我使用 service-account.php 示例并更改详细信息时,我会收到带有访问 token 的 JSON,但是当我执行 CURL 请求(与之前相同)以从用户那里获取电子邮件设置时,出现错误 “您无权访问此 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;

?>

最佳答案

您确定您的凭据没问题吗?

请尝试以下过程以确保您拥有正确的凭据。

创建您的 API key

转到 developer's console并按照以下步骤操作:

  • 选择您的项目
  • 选择菜单项“APIs & auth”
  • 选择菜单项“已注册的应用”
  • 注册一个“网络应用”类型的应用
  • 根据您要创建的应用类型,选择以下选项之一。服务器端语言应该使用这个选项:
    • 服务器应用程序 key (带 IP 锁定)

获取访问 token 和刷新 token

创建一个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_IDYOUR_CLIENT_SECRET 替换为您的客户端 ID 和客户端密码。

确保您的范围是正确的。例如,如果您想访问 Analytics,它应该是 https://www.googleapis.com/auth/analytics

如果您运行该文件,您应该会看到一个 OAuth2 批准屏幕。

如果您现在按接受,您应该得到如下所示的结果:

{
"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。


在后台连接 Google 的系统

完成上述工作后,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“code”的 GET 参数。如果存在“代码”,请获取新的访问 token 并重复此步骤(刷新您的页面)如果“代码”不存在,转到步骤 2。

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 token 是否已过期或即将过期。然后转到第 3 步。如果凭据不存在,请转到您服务的授权路径以获取授权代码并返回到第 1 步(确保 Google 重定向到您当前的 URL)。

3) 如果需要刷新,请刷新您的页面并返回步骤 1。如果不需要刷新,您就可以真正开始做您想做的事了。


但是,Google 的 PHP 库会为您处理 oAuth2 流程。如果您使用的是他们的图书馆,则三步流程中的每一步都由图书馆负责,您应该可以立即使用 Google 的服务做任何您想做的事情。我自己在 my Google Adwords dashboard 中使用了这个策略.

但是,您可以只编写自定义库并直接连接服务。下面是我几个月前写的一个项目的一些开发代码。虽然它不是开箱即用的(因为它是一个较大应用程序的一部分的 Controller ),但它应该可以帮助您了解 Google 的库在幕后处理的流程。

namespace Application;

class Controller_API_Google_Youtube extends Controller_API {
public function read() {
$scope = "https://www.googleapis.com/auth/youtube";
$this->doOauth($scope);
}

function doOauth($scope) {

$oauth2Credentials = JSON_File::load(__DIR__ . DIRECTORY_SEPARATOR . 'Config.json');

$paths = array(
'token' => 'https://accounts.google.com/o/oauth2/token',
'auth' => "https://accounts.google.com/o/oauth2/auth"
);

$refreshtime = 300;

if (isset($_GET['code'])) {
// Get access code
$query = $_GET;
unset($query['code']);
if (count($query) > 0) {
$query = '?' . http_build_query($query);
} else {
$query = '';
}

$client = \PowerTools\HTTP_Client::factory(

$responses = $client->getResponses();
$response = array_pop($responses);
$info = $response['maps']->getInfo();
$content = $response['maps']->getContent();
if ($info['http_code'] === 200) {
$output = JSON::decode($content);
$oauth2Credentials[$scope] = array();
$oauth2Credentials[$scope]['expires'] = time() + $output['expires_in'];

$this->read();
