是否可以使用 nginx 代理将获取请求转发到与端口相同的 url

Question

我有一个简单的 python 瓶 api，以及一个托管 index.html 的 nginx 服务器，该服务器向在端口 8001 上的本地主机上运行的瓶 api 发出 ajax 请求。问题是我不处理 CORS，因为它在封闭的环境中运行，它只是一个简单的 api 来管理一些活动目录的东西，它位于防火墙和基本身份验证后面。我并不真正担心跨站点脚本。我需要知道的是，如果我从

编写我的 ajax 请求

                $.ajax({ 
                   type: "GET",
                   url: "http://localhost:8001/newuser/" + "firstName=" + fname + "&lastName=" + lname + "&email=" + email + "&password=" + new_password,
                   success: function(data){        
                     alert(data);
                     document.getElementById("alert").innerHTML = data.toString();
                   }
                });

到

                $.ajax({ 
                   type: "GET",
                   url: "/newuser/" + "firstName=" + fname + "&lastName=" + lname + "&email=" + email + "&password=" + new_password,
                   success: function(data){        
                     alert(data);
                     document.getElementById("alert").innerHTML = data.toString();
                   }
                });

如何编写 nginx 重写以获取 ajax 请求并使其转到本地主机的端口 8001，如果可能的话。我看了几个例子，但找不到我需要的。

有人可以帮我解决这个问题的 nginx 代码吗，当检测到 /newuser/ 时，我需要将请求转发到 localhost 的 :8001 而不是 :80。

这是因为当我调用 localhost:8001 时，它在 Web 控制台中给了我一个 cors 错误。

我尝试在 nginx 中禁用 CORS

nginx 配置

location * {
        add_header 'Access-Control-Allow-Origin' '*';
        add_header 'Access-Control-Allow-Credentials' 'true';
        add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
        add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';

}

虚拟 nginx 配置

    location * {
         if ($request_method = 'OPTIONS') {
            add_header 'Access-Control-Allow-Origin' '*';
            #
            # Om nom nom cookies
            #
            add_header 'Access-Control-Allow-Credentials' 'true';
            add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
            #
            # Custom headers and headers various browsers *should* be OK with but aren't

            # Tell client that this pre-flight info is valid for 20 days
            #
            add_header 'Access-Control-Max-Age' 1728000;
            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-Methods' 'GET, POST, OPTIONS';

         }
         if ($request_method = 'GET') {
            add_header 'Access-Control-Allow-Origin' '*';
            add_header 'Access-Control-Allow-Credentials' 'true';
            add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
            add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';

这是我想出来的解决方案。

#
# A virtual host using mix of IP-, name-, and port-based configuration

upstream admanager.oneplatform.build {
    server localhost:8001;
}

server {
        listen       80 default_server;
        server_name  _;
        root /opt/admanager1;
        index index.html;

        auth_basic "Restricted";
        auth_basic_user_file /etc/nginx/.htpasswd;

        location /newuser/ {
                proxy_set_header X-Real-IP $remote_addr;
