README

该仓库包含一个开源PHP SDK，允许您从您的PHP应用程序中访问产品广告API。

亚马逊提供的代码副本

这是亚马逊提供的代码的几乎完全相同的公开副本，因为截至编写时，他们的版本无法通过Packagist获得。

我们没有以任何方式更改API，但我们确实清理了代码的部分内容，并更新了依赖项。以下列出了更改内容。

亚马逊的更改

• 用\GuzzleHttp\Psr7\build_query替换了使用\GuzzleHttp\Psr7\Query::build #8
• 添加了对Guzzle 7的支持 #6
• 使用PHP 8时移除了弃用警告 #13
• 使用PHP 8时移除了动态属性创建警告 #13
• 将PHP最低版本更新为PHP 8 #13
• 使用PSR-2进行代码检查 #13
• 更新了开发依赖项以反映PHP 8版本要求 #13

安装

可以使用Composer安装产品广告API PHP SDK。SDK可以通过Packagist在thewirecutter/paapi5-php-sdk软件包中找到。如果您的系统上已全局安装Composer，您可以在项目基本目录中运行以下命令将SDK作为依赖项添加：

composer require thewirecutter/paapi5-php-sdk

用法

注意：此版本的PHP产品广告API SDK需要PHP 5.5或更高版本。

简单示例：使用SearchItems搜索“哈利·波特”关键字在图书类别中的亚马逊产品
