PROSAGA码农传奇-知识图谱-nginx使用OR设置在正则表达式中为地图

<div class =“post-text”itemprop =“text”>
  
    迈克，你应该使用 ~ 符号来表示正则表达式。
  
  
    看看这里
    <a href="http://nginx.org/en/docs/http/ngx_http_map_module.html#map" rel="noreferrer">
      模块ngx_http_map_module
    </A>
  
  <BLOCKQUOTE>
    
      对于区分大小写的匹配，正则表达式应该从 ~ 符号开始，或者对于不区分大小写的匹配，应该从 ~* 符号（1.0.4）开始。正则表达式可以包含命名和位置捕获，以后可以在其他指令中使用结果变量。
    
  </BLOCKQUOTE>
  
    正确的配置应该是：
  
   <pre>
 <code>
 map $request_uri $redirect_uri {
 ~/(?<lang>(en|de|fr))/oldname /$lang/newname;
}

</code>
 </pre>
  
    祝好运！

    以下是基于默认配置的完整配置（echo指令由nginx-echo-module提供）
  
   <pre>
 <code>
 #user nobody;
worker_processes 1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

    worker_connections  1024;

 }

server {
        listen       80;
        server_name  localhost;

#charset koi8-r;

#access_log  logs/host.access.log  main;

location / {
            echo $redirect_uri;
        }

#error_page  404              /404.html;

# redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

# proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;

        #
        #location ~ \.php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}

# deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }

# another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {

    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

#    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

# HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

#    ssl_certificate      cert.pem;

    #        index  index.html index.htm;
    #    }
    #}

}

</code>
 </pre>
  
    这是我的测试用例：
  
   <pre>
 <code>
 yxr nginx # curl localhost/en/oldname
/en/newname
yxr nginx # curl localhost/de/oldname
/de/newname
yxr nginx # curl localhost/fr/oldname
/fr/newname
yxr nginx # curl localhost/cn/oldname

yxr nginx #

</code>
 </pre>

    正如@Mike指出的那样，这至少需要
     <code>
 nginx/1.11.0
 </code>
    。
