Question

我在https://server.mysite.com/level/two上有一个网页

我在以下位置提供api端点： https://server.mysite.com:17777/twbets

我遇到错误：

Access to XMLHttpRequest at 'https://server.mysite.com:17777/twbets' from origin 'https://server.mysite.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

如何使该错误消失？我觉得我已经尝试了Nginx配置文件的每个排列，但无法使其正常工作。下面是我的网站当前可用的配置文件的位置部分。对于每种请求类型，我不需要单独的部分，这只是我尝试过的最新内容，因为另一个问题提出了建议。

server {

    server_name server.mysite.com;
    root /var/www;

        location ^~ /level/two {
        if ($request_method = 'OPTIONS') {
            add_header 'Access-Control-Allow-Origin' '*';
            #
            #
            add_header 'Access-Control-Allow-Credentials' 'true';
            add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
            #

            add_header 'Content-Type' 'text/plain charset=UTF-8';
            add_header 'Content-Length' 0;
            return 204;
         }
         if ($request_method = 'POST') {
            add_header 'Access-Control-Allow-Origin' '*';
            add_header 'Access-Control-Allow-Credentials' 'true';

            add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';
         }

            add_header 'Access-Control-Allow-Origin' '*';
            add_header 'Access-Control-Allow-Credentials' 'true';

         }
    }
