我nginx是这么配置的：

                listen 443 ssl;
                server_name one.liuweiqing.top;

                        # 允许跨域的设置
                        add_header 'Access-Control-Allow-Origin' '*' always;

                        proxy_set_header Connection "upgrade";
                        # 预检请求
                        if ($request_method = 'OPTIONS') {
                                add_header 'Access-Control-Allow-Origin' "$http_origin";

                                add_header 'Access-Control-Allow-Headers' '*'; # 允许所有头
                                return 204;
              
上面的配置解决了oneapi的问题，但是没有解决这个网站的问题，继续求助

这个比较通用它既避免了原始程序在没有处理跨域问题时返回401未授权问题，又添加了对所有响应添加跨域请求的功能
