当我在上面代码的 APIID 字段中设置我的 Developer API id 并运行时，它会在网页上显示 JSON 和 CSV 格式。但是我无法将网页上显示的这个 csv 数据保存到我的本地硬盘。
我看到一些可以创建文件并保存在硬盘上的 php 代码，但我无法使用这段代码使其工作。
我是新手，我在 eBay 上有 300 种产品的大量库存，我需要以 csv 格式下载这些产品，以便我可以将相同的产品提供给其他电子商务网站。
eBay 网站以 JSON 格式返回数据，也以 XML 格式返回数据，但我不想使用其他格式检索数据，因为到目前为止，我可以通过查看网络上的其他代码来查看网页上的 CSV 数据并使其与上面粘贴的 eBay 开发者网站上的示例代码一起使用。
我得到的输出是:-

最佳答案
您的 gson 数组由列表中每个项目几乎相同的 gson 结构组成，没有简单的方法来处理它，只能编写一个长函数来处理 json 数组中的每个项目。首先添加标题，然后为标题中的每个项目添加一行数据，
看看这段代码是否适合你，我对 json 数组中的项目进行了测试并且它有效，
