Nginx 重写包含带空格的查询字符串的参数

Nginx 重写包含带空格的查询字符串的参数

我们在另一台主机上有一个 SAS 9.4 VisualAnalyticsViewer 页面，我想通过 443 公开展示。内部 SAS 服务器运行 Apache Tomcat 并仅监听 8343。如果可能的话，我宁愿不必更改 SAS 框上的每个 proxy_pass 语句，也不必自定义其端口，只需通过端口 443 提供单个页面。目前，我们的 Web 服务器使用 IFrames 链接到 8343 上的内部服务器，这些链接可以工作，但由于远程防火墙限制，限制了公共用户访问。我想将 Nginx 放在 Tomcat 服务器前面，让它监听 443。我的问题是处理重写语句中的空格。有人可以向我展示如何实现此目的的正确语法或正则表达式吗？

请注意；绕过 Nginx 并将带有空格的完整内部 URL 粘贴到本地浏览器中是有效的。

应用场景：

External Client Request:

https://apppub.domain.com/appVisualAnalyticsViewer Or,

https://apppub.domain.com/appVisualAnalyticsViewer/VisualAnalyticsViewer_guest.jsp?reportName=Report with Spaces&reportPath=/Some Data Path with Spaces/SubFolder/REPORT&appSwitcherDisabled=true

Nginx 代理检查 URI 查询字符串，然后将其重写或附加到端口 8343 上的内部 SAS 服务器。

Nginx Reverse Proxy:

https://appint.domain.com:8343/appVisualAnalyticsViewer/VisualAnalyticsViewer_guest.jsp?reportName=Report with Spaces&reportPath=/Some Data Path with Spaces/REPORT&appSwitcherDisabled=true

客户响应：

https://apppub.domain.com/appVisualAnalyticsViewer/（从远程客户端浏览器 URL 中剥离查询字符串）

以下是 apppub.conf（仅限此网站）、response.conf 和 proxy.conf 的完整配置，它们均由同一代理服务器上的多个站点使用。


Nginx Config:

    upstream appint { 
    least_conn; 
    server appint.domain.com:8343; 
}

server {

      listen 80;
      server_name apppub.domain.com;

      access_log off;
      autoindex off;

      location / {
         # Rate limit first 6 requests and burst next 4. Reject everything else
         limit_req zone=one burst=10 delay=6;
         return 301 https://$server_name$request_uri;
      }

}

server {

    listen 443 ssl;

     server_name apppub.domain.com;

   # Site Specific Logging Metrics
     access_log /var/log/nginx/apppub.access.log main_ext;
     error_log /var/log/nginx/apppub.error.log warn;

    location ~ ^/appVisualAnalyticsViewer {

       if ($args !~* "Report Name with Spaces"){
           set $report "VisualAnalyticsViewer_guest.jsp?reportName=Report with Spaces&reportPath=/Some Data Path with Spaces/REPORT&appSwitcherDisabled=true";
           rewrite ^(.*)$ $report break; 
           **(What's the correct syntax for a rewrite?)**
       }

       include /etc/nginx/conf.add/proxy.conf; (See Below)
       proxy_pass https://appint;

     }

你们可能对此感兴趣。我找出了语法错误，并最终使用位置周围的单引号纠正了它。
