Google Analytics API：如何解决 OAuth2 缺少范围参数错误？

Question

我正在尝试让这个示例工作：https://developers.google.com/analytics/devguides/config/mgmt/v3/quickstart/web-php#enable

我得到的错误是“错误：invalid_request, Missing required parameter:scope”

为了安装google api资源，我使用了composer这个命令：

php composer.phar require google/apiclient:^2.0.0@RC

这在我的根站点文件夹中安装了“供应商”文件夹。我的 index.php 和 oauth2callback.php 文件位于“public_html”文件夹中。

这是我在 index.php 中的内容：

<?php
// Load the Google API PHP Client Library.
require_once '../vendor/autoload.php';

// Start a session to persist credentials.
session_start();

// Create the client object and set the authorization configuration
// from the client_secretes.json you downloaded from the developer console.
$client = new Google_Client();
$client->setAuthConfigFile('client_secrets.json');
$client->addScope(Google_Service_Analytics::ANALYTICS_READONLY);

// If the user has already authorized this app then get an access token
// else redirect to ask the user to authorize access to Google Analytics.
if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
    // Set the access token on the client.
    $client->setAccessToken($_SESSION['access_token']);

    // Create an authorized analytics service object.
    $analytics = new Google_Service_Analytics($client);

    // Get the first view (profile) id for the authorized user.
    $profile = getFirstProfileId($analytics);

    // Get the results from the Core Reporting API and print the results.
    $results = getResults($analytics, $profile);
    printResults($results);
} else {
    $redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . '/oauth2callback.php';
    header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
}


function getFirstprofileId(&$analytics) {
    // Get the user's first view (profile) ID.

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

    if (count($accounts->getItems()) > 0) {
        $items = $accounts->getItems();
        $firstAccountId = $items[0]->getId();

        // Get the list of properties for the authorized user.
        $properties = $analytics->management_webproperties
        ->listManagementWebproperties($firstAccountId);

        if (count($properties->getItems()) > 0) {
            $items = $properties->getItems();
            $firstPropertyId = $items[0]->getId();

            // Get the list of views (profiles) for the authorized user.
            $profiles = $analytics->management_profiles
            ->listManagementProfiles($firstAccountId, $firstPropertyId);

            if (count($profiles->getItems()) > 0) {
                $items = $profiles->getItems();

                // Return the first view (profile) ID.
                return $items[0]->getId();

            } else {
                throw new Exception('No views (profiles) found for this user.');
            }
        } else {
            throw new Exception('No properties found for this user.');
        }
    } else {
        throw new Exception('No accounts found for this user.');
    }
}

function getResults(&$analytics, $profileId) {
    // Calls the Core Reporting API and queries for the number of sessions
    // for the last seven days.
    return $analytics->data_ga->get(
    'ga:' . $profileId,
    '7daysAgo',
    'today',
    'ga:sessions');
}

function printResults(&$results) {
    // Parses the response from the Core Reporting API and prints
    // the profile name and total sessions.
    if (count($results->getRows()) > 0) {

        // Get the profile name.
        $profileName = $results->getProfileInfo()->getProfileName();

        // Get the entry for the first entry in the first row.
        $rows = $results->getRows();
        $sessions = $rows[0][0];

        // Print the results.
        print "<p>First view (profile) found: $profileName</p>";
        print "<p>Total sessions: $sessions</p>";
    } else {
        print "<p>No results found.</p>";
    }
}

这就是我的 oauth2callback.php 中的内容：

<?php
require_once '../vendor/autoload.php';

// Start a session to persist credentials.
session_start();

// Create the client object and set the authorization configuration
// from the client_secrets.json you downloaded from the Developers Console.
$client = new Google_Client();
$client->setAuthConfigFile('client_secrets.json');
$client->setRedirectUri('http://' . $_SERVER['HTTP_HOST'] . '/oauth2callback.php');

// Handle authorization flow from the server.
if (! isset($_GET['code'])) {
    $auth_url = $client->createAuthUrl();
    header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL));
} else {
    $client->authenticate($_GET['code']);
    $_SESSION['access_token'] = $client->getAccessToken();
    $redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . '/';
    header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
}

我已经阅读了类似的错误，并看到有人通过添加以下内容发布：

passport.authenticate('google', {scope: 'https://www.googleapis.com/auth/plus.login'});

它会起作用，但我不知道在哪里添加它，也不知道它是否能解决我的问题。

另外，不知道有没有必要知道，但是client_secrets.json文件和index.php文件在同一个文件夹下； (public_html) 文件夹。

顺便说一句，在我的 Google API 管理器中，我将授权重定向 URI 设置为仅“http://localhost:8080/oauth2callback.php”，这是我在这个问题中链接的第一个参考所说的。我不认为这应该是一个问题，只是想在这里得到我的全部问题。

谁能帮我理解从这里做什么？

我会附上我看到的错误截图。

Answer 1

改变这个（index.php）；

$client = new Google_Client();
$client->setAuthConfigFile('client_secrets.json');
$client->addScope(Google_Service_Analytics::ANALYTICS_READONLY);

到这个；

$client = new Google_Client();
$client->setAuthConfigFile('client_secrets.json');
$client->addScope('https://www.googleapis.com/auth/analytics.readonly');

另外，您的回调中缺少 addscope，请更改此 (oauth2callback.php)；

$client = new Google_Client();
$client->setAuthConfigFile('client_secrets.json');
$client->setRedirectUri('http://' . $_SERVER['HTTP_HOST'] . '/oauth2callback.php')

到这个；

$client = new Google_Client();
$client->setAuthConfigFile('client_secrets.json');
$client->setRedirectUri('http://' . $_SERVER['HTTP_HOST'] . '/oauth2callback.php')
$client->addScope('https://www.googleapis.com/auth/analytics.readonly');

您可以在这里找到更多信息https://developers.google.com/api-client-library/php/start/get_started#setup

旁注；

另外，我不知道是否有必要知道，但是 client_secrets.json 文件与 index.php 文件位于同一文件夹中； (public_html) 文件夹。

不建议这样做，您应该将 json 文件放在 'webapps' 目录之外，例如 config 文件夹。
