无法使用 PHP API 创建 Google 文档

Question

    $client->setAccessToken($_SESSION['access_token']);
    $service = new Google_Service_Docs($client);

    $title = $_SESSION['class'].' - '.date("Y-m-d");
    $document = new Google_Service_Docs_Document(array(
        'title' => $title
    ));

    //everything works until here. For some reason, this line doesn't run. It doesn't even proceed.
    $document = $service->documents->create($document);
    
    //this line isn't even printed
    print_r("success!");

    $documentId = $document->documentId;

    header('Location: https://docs.google.com/document/d/'.$documentId);
    exit();

我已经为此苦苦思索了好几个小时。我不知道为什么我不能创建一个新的 Google Doc。除了谷歌之外，网上绝对没有这样的例子，这里的大部分代码都是直接从他们那里复制而来的。

这是我在分配标题后但在执行服务以创建新文档之前打印 $document 时得到的结果。

PHP Quickstart 提供有关如何使用 Google Docs API 阅读 Google 文档的完整教程。

要创建新文档，请使用上面的示例并替换：

$documentId = '195j9eDD3ccgjQRttHhJPymLJUCOUjs-jmwTrekvdjFE';
$doc = $service->documents->get($documentId);
printf("The document title is: %s\n", $doc->getTitle());

与：

$title = 'My Document';
$document = new Google_Service_Docs_Document(array(
    'title' => $title
));

$document = $service->documents->create($document);
printf("Created document with title: %s\n", $document->title);

另外，请确保将项目的 SCOPE 更改为 Google_Service_Docs::DOCUMENTS，并在运行代码之前，删除 Token.json 以重新启动验证过程并使用您指定的范围创建新令牌。

您的代码应如下所示：

<?php
require __DIR__ . '/vendor/autoload.php';

/**
 * Returns an authorized API client.
 * @return Google_Client the authorized client object
 */
function getClient()
{
    $client = new Google_Client();
    $client->setApplicationName('Google Docs API PHP Quickstart');
    $client->setScopes(Google_Service_Docs::DOCUMENTS);
    $client->setAuthConfig('credentials.json');
    $client->setAccessType('offline');

    // Load previously authorized credentials from a file.
    $credentialsPath = expandHomeDirectory('token.json');
    if (file_exists($credentialsPath)) {
        $accessToken = json_decode(file_get_contents($credentialsPath), true);
    } else {
        // Request authorization from the user.
        $authUrl = $client->createAuthUrl();
        printf("Open the following link in your browser:\n%s\n", $authUrl);
        print 'Enter verification code: ';
        $authCode = trim(fgets(STDIN));

        // Exchange authorization code for an access token.
        $accessToken = $client->fetchAccessTokenWithAuthCode($authCode);

        // Store the credentials to disk.
        if (!file_exists(dirname($credentialsPath))) {
            mkdir(dirname($credentialsPath), 0700, true);
        }
        file_put_contents($credentialsPath, json_encode($accessToken));
        printf("Credentials saved to %s\n", $credentialsPath);
    }
    $client->setAccessToken($accessToken);

    // Refresh the token if it's expired.
    if ($client->isAccessTokenExpired()) {
        $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
        file_put_contents($credentialsPath, json_encode($client->getAccessToken()));
    }
    return $client;
}

/**
 * Expands the home directory alias '~' to the full path.
 * @param string $path the path to expand.
 * @return string the expanded path.
 */
function expandHomeDirectory($path)
{
    $homeDirectory = getenv('HOME');
    if (empty($homeDirectory)) {
        $homeDirectory = getenv('HOMEDRIVE') . getenv('HOMEPATH');
    }
    return str_replace('~', realpath($homeDirectory), $path);
}

// Get the API client and construct the service object.
$client = getClient();
$service = new Google_Service_Docs($client);

$title = 'My Document';
$document = new Google_Service_Docs_Document(array(
    'title' => $title
));

$document = $service->documents->create($document);
printf("Created document with title: %s\n", $document->title);
