Django csrf 令牌无法读取

Question

我正在写一个网站，使用Vue作为前端框架，django作为后端框架。我已将 csrf 令牌包含在从前端到后端的每个请求中，以确保不会收到 403 Forbidden 错误。所有请求都正常并且功能正常。现在这里是事情不起作用的地方。我将代码作为压缩文件发送给其他人以供他们运行。前端和后端都运行没有问题，只是无法执行对后端的请求。每个请求都会返回 403 Forbidden 错误，这是因为请求中未包含 csrf 令牌。请记住，这是相同的代码，可以在一台笔记本电脑上运行，但不能在另一台笔记本电脑上运行。我可以做什么来解决这个问题？

前端到后端的请求：

try{
        const response = await fetch('http://127.0.0.1:8000/logout', {
            method:'POST',
            headers:{
                'Content-Type': 'application-json',
                'X-CSRFToken': Cookies.get('csrftoken'), 
            } ,
            credentials: 'include',
        })

尝试在不起作用的笔记本电脑上打印 csrf 令牌时的值：

undefined

问题最终是在一台笔记本电脑上，前端在 127.0.0.1 上运行，而在另一台笔记本电脑上则在 localhost 上运行。这导致 csrf 令牌被设置在一个域上，该域是后端的 127.0.0.1，我试图从本地主机读取它。我只需要将其添加到我的 vite.config 文件中，以确保前端与后端在同一域上运行：

  server: {
    host: '127.0.0.1'
  }
