这应该很容易,但是,我一直在努力获取正确的正则表达式语法,以便重写在某个位置下工作。简而言之,我需要搜索带有空格的特定查询字符串,然后将相同的参数传回内部 Web 服务器。我在这里遗漏了什么?
以下是相关位置:
location = /SubDirectory/ {
if ($args !~* "Report Files"){ #Contains Spaces
set $report "LongString_guest.jsp?reportName=Report with several spaces&reportPath=/Share/Reports/REPORT&appSwitcherDisabled=true";
rewrite ^(.*)$ $report break;
}
proxy_pass https://srvweb; #upstream loadbalanced servers
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。
