Node.js中CORS跨域报错求助：配置及扩展均无效

在Chrome浏览器打开前端页面时，控制台持续弹出以下两个错误：

Access to XMLHttpRequest at 'https://hog.simplify.jobs/decide/?v=3&ip=1&_=1688782636903&ver=1.57.2' from origin 'http://localhost:8080' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

POST https://hog.simplify.jobs/decide/?v=3&ip=1&_=1688782636903&ver=1.57.2 net::ERR_FAILED 404 contentScript.bundle.js:1 

已尝试以下方案，但均未解决问题：

• 安装Chrome跨域扩展，无效
• 在Node.js后端配置CORS，两种方式都试过：
  1. 使用cors库：

     app.use(cors({origin: '*'}));
     

  2. 手动设置响应头：

     app.use(function (req, res, next) {
         res.setHeader('Access-Control-Allow-Origin', '*');
         res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
         res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With, content-type');
         res.setHeader('Access-Control-Allow-Credentials', true);
         next();
     });
