PHP Firebase帮助-设置JWT

在我的服务器上，我运行了几个PHP文件来读取我的Firebase实时数据库。根据需要，我需要设置自定义令牌来运行。Firebase文件说我需要归还这个

  return JWT::encode($payload, $private_key, "RS256");

我如何准确地引用JWT类？我下载了一个JWT库，但我不知道如何在我的项目中实现它。任何帮助都会很好，我主要是一名移动开发人员，对PHP几乎没有经验

图书馆使用。如果您来自Android开发背景，Composer是PHP的依赖项管理器，类似于Java中的Maven。您需要知道如何使用PHP的require/include函数在PHP中导入类。您需要一些php经验才能使用composer

为了在不使用composer的情况下使用库，您可以使用以下示例代码：（我在

jwt

文件夹中下载了库）

您正在使用composer吗？
