如何编写NGINX Url代理？

我想转换url

https://example.com/?city=FLorida&type=America&date=2019-06-06-15:15

当用户请求第二个url时，使用nginx作为代理为第一个url提供服务。

困难在于将月份名称转换为数字，这可以通过使用带有12个正则表达式的

映射来解决。有关详细信息，请参阅

第一个示例执行
映射中的所有操作。我使用了重定向来测试它，因为我不知道您打算如何在内部处理重写的URI

map $uri $newuri {
    default  0;
    ~*^/(?<city>\w+)/(?<type>\w+)/(?<day>\d\d)-jan(uary)?-(?<year>\d\d\d\d)-(?<hour>\d\d)(?<min>\d\d)$
       "/?city=$city&type=$type&date=$year-01-$day $hour:$min";
    ~*^/(?<city>\w+)/(?<type>\w+)/(?<day>\d\d)-feb(ruary)?-(?<year>\d\d\d\d)-(?<hour>\d\d)(?<min>\d\d)$
        "/?city=$city&type=$type&date=$year-02-$day $hour:$min";
    ~*^/(?<city>\w+)/(?<type>\w+)/(?<day>\d\d)-mar(ch)?-(?<year>\d\d\d\d)-(?<hour>\d\d)(?<min>\d\d)$
        "/?city=$city&type=$type&date=$year-03-$day $hour:$min";
    ~*^/(?<city>\w+)/(?<type>\w+)/(?<day>\d\d)-apr(il)?-(?<year>\d\d\d\d)-(?<hour>\d\d)(?<min>\d\d)$

server {
