Reactjs 代理错误：Could not proxy request api from localhost：3000 to http：localhost：8000 (ECONNREFUSED)

我有一个React前端，它使用jwt与Django后端进行身份验证.后端工作正常，使用django视图连接正常，但当我try 代理React的请求时，它会给我一个连接拒绝错误.

代理错误:无法代理请求/api/auth/token/Acquire/from localhost:3000到http://localhost:8000(Econrefused).

连接到http://localhost:8000/api/auth/token/obtain/正常工作.使用Axios发送POST请求也可以正常工作，并返回标记json.但当我用node代理它时，它就不起作用了.

在我的package.json年中，我有:

  "proxy": {
    "/api/*":  {
      "target": "http://localhost:8000"
    }
  },

编辑:Public repo.如果安装了docker，您可以轻松运行.(使用1个图像和2个容器).克隆后只需运行docker-compose build，然后运行docker-compose up.

Edit2:请求的标题:
