如何通过授权的上游代理将我们的客户端请求传递到特定的网址？

我必须输入用户名/密码来连接上游代理，然后在我的浏览器中以 HTTP 和 HTTPS 协议（我可以在 Firefox 手动代理选项中设置）打开一些网页（例如 jj.com）。所以我想为其他客户端打开 jj.com 提供访问权限，而无需知道并输入用户名/密码并通过 NginX 在她/他的浏览器中打开网页（如 jj.com）。

 +--------------------+                      +---------------------+
 |                    |                      | upstramProxy:9090   |       +----------+
 | Client browser     |                      | user:user-003       |+----->| jj.com   |
 |                    |                      | pass:123456         |<------+----------+
 +--------------------+                      +---------------------+
     |  ^ (myProxyService.com:8080/pr?url=jj.com)   |  ^
     |  |                                           |  |
     |  |                                           |  |
     |  |                                +---------------------+
     |  +--------------------------------| myProxyService.com  |
     |                                   | NginX in myServer   |
     +---------------------------------->| Listen to 8080      |
                                         +---------------------+

有可能吗？如果还有其他方法我想知道。

witch java 中的简单 java web 应用程序通过名为 myProxyServer 的第三方代理发送所有请求

 public static void processRequest(HttpServletRequest req, HttpServletResponse resp) {
    try {
        PrintWriter out = resp.getWriter();
        System.out.println(req.getRequestURI());
        System.out.println(req.getRequestURL());
        jjTools.ShowAllParameter(req);
        final BasicCredentialsProvider credsProvider = new BasicCredentialsProvider();
        credsProvider.setCredentials(
                new AuthScope("thirdpartyProxy.com", 8080),
                new UsernamePasswordCredentials("username", "passss".toCharArray())
        );
        try (final CloseableHttpClient httpclient = HttpClients.custom()
                .setDefaultCredentialsProvider(credsProvider).build()) {
            
            final HttpHost target = new HttpHost("https", "www.targetwebSite.com", 443);
            final HttpHost proxy = new HttpHost("http", "thirdpartyProxy.com", 8080);
            final RequestConfig config = RequestConfig.custom()
                    .setProxy(proxy)
                    .setCircularRedirectsAllowed(true)
                    .build();                                        
            final HttpGet httpget = new HttpGet(req.getRequestURI().replaceFirst("/My_Proxy/", "/"));                
            httpget.setConfig(config);                

            System.out.println("Executing request " + httpget.getMethod() + " " + httpget.getUri()
                    + " via " + proxy);

            try (final CloseableHttpResponse response = httpclient.execute(target, httpget)) {
                System.out.println("----------------------------------------");
                resp.setContentType(response.getHeader("Content-Type").toString());
                System.out.println(response.getHeader("Content-Type").toString());
                System.out.println(response.getCode() + " " + response.getReasonPhrase());
                out.print(EntityUtils.toString(response.getEntity())+"<scipt>alert");
            }
        }
        out.close();
    } catch (Exception ex) {
        Logger.getLogger(Listener.class.getName()).log(Level.SEVERE, null, ex);
    }
}

然后你必须像下面的代码那样配置 nginX.conf：

server {
    listen          80;
    server_name         targetwebSite.localhost;
    location / {
        #proxy_set_header X-Forwarded-Host $host;
        #proxy_set_header X-Forwarded-Server $host;
        #proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://localhost:8080/My_Proxy/;
    }

}

对于结果，它将适用于所有包含其 CSS 和 JavaScript 文件的页面

http://targetwebSite.localhost/

地址
