致命错误:在数据存储中找不到类“GDS网关”.php在第 2 行 - Fatal error: Class 'GDSGateway' not found in datastore.php on line 2

Fatal error: Class 'GDSGateway' not found in datastore.php on line 2

我试图测试这个谷歌数据存储库的PHP。我已将GDS文件夹复制到应用程序的根目录，并在同一根目录中创建了一个php文件。当我运行代码时，我收到此错误Fatal error: Class 'GDS'Gateway' not found in /home/personal/SampleApp/datastore.php on line 2

数据存储.php

<?php
    $obj_client = GDS'Gateway::createGoogleClient('AppID', 'xxxx@developer.gserviceaccount.com', 'appKeyFile.p12');
    $obj_gateway = new GDS'Gateway($obj_client, 'AppID');
    $obj_book_store = new GDS'Store($obj_gateway, 'Book');
    $obj_book = new GDS'Entity();
    $obj_book->title = 'Romeo and Juliet';
    $obj_book->author = 'William Shakespeare';
    $obj_book->isbn = '1840224339';
    $obj_book_store->upsert($obj_book);
?>

我在这里缺少什么吗？

您是否使用作曲家来拉入库？如果没有，则需要编写自己的自动加载脚本或添加以下行

include_once 'src/GDS/Entity.php';
include_once 'src/GDS/Gateway.php';
include_once 'src/GDS/Store.php';
