nginx的http模块

html的页面

[root@python html]# echo first > first/1.txt
[root@python html]# echo second  > second/1.txt
[root@python html]# echo third  > second/1.txt
[root@python html]# echo second  > second/1.txt
[root@python html]# echo third  > third/1.txt

url地址重写

rewrite模块:rewrite指令

sysntax : rewrite  regex replacement  [flag];

Default:   -

Context:  server,location,if

功能:

将regex指定的URL替换成replacement这个新的url可以使用正则表达式

当replacement以http://或者https://或$schema开头,则直接返回302重定向

替换后的url根据flag指定的方式进行处理

last:用replacement这个url进行新的location匹配

break:break指令是停止当前脚本指令的执行,等价于独立的break指令

redirect:返回302重定向(临时重定向)

permanent:返回301重定向(永久重定向)

server {
        server_name haha.com;
        listen 8080;
        error_page 404 /403.html;
        #return 405;
        location /{
                #return 404 "find nothing!
";
        }
	root html/;
	location /first {
		rewrite /first(.*) /second$1 last;  
		return 200 1first!
';
		}
	location /second {
		#rewrite /second(.*) /third$1 break;
		rewrite /second(.*) /third$1;
		return 200 'second!
';
		}
	location /third {
		return 200 'third!
';
	}
}

  测试

[root@python vhast]# curl haha.com:8080/first/1.txt
second!

  修改配置

[root@python vhast]# cat test.conf 
server {
        server_name haha.com;
        listen 8080;
        error_page 404 /403.html;
        #return 405;
        location /{
                #return 404 "find nothing!
";
        }
	root html/;#到这里找请求的资源
	location /first {
		rewrite /first(.*) /second$1 last;
		return 200 1first!
';
		}
	location /second {
		rewrite /second(.*) /third$1 break;  表示跳出指令块后
		#rewrite /second(.*) /third$1;
		return 200 'second!
';
		}
	location /third {
		return 200 'third!
';
