Django后端对印前判断请求未通过访问控制判断给我以下回应：否访问控制允许来源

我几乎什么都试过了，从研究到研究.基本上，我有我的前端服务器和后端服务器.我的前端服务器从运行Django的后端服务器收到错误.

这是我在Django应用程序中的设置

 .then(data => {
  processRecommendation(data);
 })

我将nginx设置为反向代理服务器，我有这个https://127.0.0.1:8000

我没有什么可以try 的东西了，我真的不想让所有人都访问我的服务器.

我基本上已经try 了我能想到的所有方法，试图让这件事奏效.这是我的睡衣

       location / {
                proxy_pass https://127.0.0.1:8000;
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
        }

我以为添加CORS_ALLOW_ALL_RESOURCES=True会让我达到一个可以工作的状态，但我错了.我也真的不想那样做.

错误消息

CORS策略已阻止从源‘appli.asdf.com’访问位于‘appliai.asdf.com/getPredictions’的XMLHttpRequest.:对印前判断请求的响应未通过访问控制判断:请求的资源上不存在‘Access-Control-Allow-Origin’标头.Xhr.js:220 post appliai.asdf.com/getPredictions net::Err_FAILED

我暂时负责这项工作，直到我能解决所有的问题.
