如何在 Google Cloud Platform 上使用 Firestore 正确部署 PHP 应用程序？

Question

我正在 PHP 应用程序 中设置 Cloud Firestore Google 云平台 基于 https://github.com/googleapis/google-cloud-php-firestore.

部署到 App Engine 后，我看到“new FirestoreClient();”不起作用，但代码相同在 localhost 上正常运行。我该如何解决这个问题？

代码：

index.php

<?php

require_once 'vendor/autoload.php';
use Google\Cloud\Firestore\FirestoreClient;

echo "Hello Firestore";

$firestore = new FirestoreClient();
$collectionReference = $firestore->collection('boards');
$documentReference = $collectionReference->document("b-1");
$snapshot = $documentReference->snapshot();
$data = $snapshot->data();
var_dump($data);

echo "Goodbye Firestore";
?>

app.yaml

runtime: php72

handlers:
- url: /favicon\.ico
  static_files: favicon.ico
  upload: favicon\.ico

- url: /images
  static_dir: images

- url: /stylesheets
  static_dir: stylesheets

    "require": {

        "grpc/grpc": "^1.19"
    }
}

用本地主机输出

Hello Firestore

array(4) { ["headline"]=> string(1) "b" ["amount_of_threads"]=> int(1) ["description"]=> string(22) "Flood and nothing else" ["content_type"]=> string(7) "default" }

Goodbye Firestore

使用Google云平台

输出

Hello Firestore

我认为您可能缺少 php.ini 文件来启用 Cloud Firestore 需要的 grpc 扩展：

php.ini

extension=grpc.so

将此文件包含在您的申请中。查看这些文档：

另外，您提到在您的日志中没有看到任何错误。错误可能已在默认情况下不可见的不同文件中报告。以下是如何在控制台中查看它们：
