Question

我正在尝试使用Google分析API。我在开发者控制台中创建了一个帐户，我使用OAuth2授予对用户数据的访问权限。所以我有我的refresh_token。但现在，我想在GA中获取我可以访问的帐户的所有profilesID。我按照Google的官方教程进行操作，我收到了此错误：

{
"error": {
    "errors": [{
        "domain": "global",
        "reason": "required",
        "message": "Login Required",
        "locationType": "header",
        "location": "Authorization"
    }],
    "code": 401,
    "message": "Login Required"
}

}

我看到我错过了凭证，但我不知道如何在此次通话中通过access_token。这是我的代码：

$client = new Google_Client();
    $client->setApplicationName("APP_NAME");
    $client->setAuthConfig(GA_KEYS_JSON);

    $client->setScopes(['https://www.googleapis.com/auth/analytics.readonly']);
    $analytics = new Google_Service_Analytics($client);

    // Get the list of accounts for the authorized user.
    $accounts = $analytics->management_accounts->listManagementAccounts();
    $items = $accounts->getItems();

    var_dump($items);die();

有什么想法吗？

请看这里：https://developers.google.com/api-client-library/php/auth/web-app#exchange-authorization-code

function jsonToCsvConvertor(JSONData, reportTitle) {
    //If JSONData is not an object then JSON.parse will parse the JSON string in an Object
    var arrData = typeof JSONData !== 'object' ? JSON.parse(JSONData) : JSONData,                    
        csv = '',

        key1,
        i,
        subGridData;

    //Set Report title in first row or line

并刷新访问令牌：https://developers.google.com/api-client-library/php/auth/web-app#offline

Answer 2

好的，我找到了一个解决方案，但可能还有另一种提高效率并使用Google_Client类的方式。

public function generateToken($refresh_token)
{
    $data = [
        "client_id" => "ClientID",
        "client_secret" => "SecretID",
        "refresh_token"=> "RefreshToken",
        "grant_type"=> "refresh_token"
    ];

    $url = "https://www.googleapis.com/oauth2/v4/token";
    $res = post_request($url, $data);
    $res = json_decode($res, true); 
    return $res["access_token"];
}

Answer 3

$客户端 - ＆GT; fetchAccessTokenWithRefreshToken（$客户端 - ＆GT; getRefreshToken（））;

当您可以提供刷新令牌时，

可用于获取新的访问令牌。

以下是从我的示例项目中删除的一些代码。 Google analytics v3

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

if (! isset($_GET['code'])) {
    $client = buildClient();
    $auth_url = $client->createAuthUrl();
    header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL));
} else {
    $client = buildClient();
    $client->authenticate($_GET['code']); // Exchange the authencation code for a refresh token and access token.
    // Add access token and refresh token to seession.
    $_SESSION['access_token'] = $client->getAccessToken();
    $_SESSION['refresh_token'] = $client->getRefreshToken();    
    //Redirect back to main script
    $redirect_uri = str_replace("oauth2callback.php",$_SESSION['mainScript'],$client->getRedirectUri());

Answer 4

我使用Google_Client（）类找到了更好的解决方案：

$client->refreshToken($theRefreshTokenYouHadStored);

所以不需要执行POST请求来获取新的令牌，所有这些都是隐式地使用了refreshToken（）方法。
