php - 如何在 php 中初始化 Cloud Firestore？

Question

我按照这些教程在 PHP 中使用 Firestore:
https://github.com/googleapis/google-cloud-php-firestore https://firebase.google.com/docs/firestore/quickstart

但是当我加载我的页面时，会显示此消息:

Google\ApiCore\ValidationException: Error rendering 'projects/{project=}/databases/{database=}': expected binding 'project' to match segment '{project=*}', instead got null Provided bindings: Array ( [project] => [database] => (default) ) in C:\wamp64\www\php\vendor\google\gax\src\ResourceTemplate\RelativeResourceTemplate.php on line 238'

这是我的代码:

Composer .json:

 {
    "require": {
        "google/cloud-firestore": "^1.4",
        "grpc/grpc": "v1.19.0"
    }
}

index.php(示例的副本):

require ('vendor/autoload.php');
use Google\Cloud\Firestore\FirestoreClient;

/**
 * Initialize Cloud Firestore with default project ID.
 * ```
 * initialize();
 * ```
 */
    // Create the Cloud Firestore client
    $db = new FirestoreClient();
    printf('Created Cloud Firestore client with default project ID.' . 
PHP_EOL);



$docRef = $db->collection('users')->document('lovelace');
$docRef->set([
    'first' => 'Ada',
    'last' => 'Lovelace',
    'born' => 1815
]);

看起来您没有设置默认的项目 ID。

尝试设置 GCLOUD_PROJECT环境变量到您的项目 ID。

set GCLOUD_PROJECT=PROJECT_ID

您还可以尝试像这样设置项目 ID:

$db = new FirestoreClient([
        'projectId' => 'my-project-id',
    ]);
