last :相当于 Apache 里的(L)标记，表示完成rewrite 匹配;
break: 本条规则匹配完成后，终止匹配，不再匹配后面的规则。
# 其中last 和 break 用来实现 URL 重写时，浏览器地址栏URL 地址不变
redirect: 返回 302 临时重定向，浏览器地址会显示跳转后的 URL 地址。
permanent: 返回 301永久重定向，浏览器地址栏会显示跳转后的URL 地址
#不配置将显示304

根据浏览器，agent跳转

sh 复制代码 
server {
	listen 80;
	server_name www.myng.com.zh  www.myng.com.en;
	root /code;
	index index.html;
    location / {
#场景1: 根据用户浏览器的语言，自动跳转至不同的页面。	
        if ($http_accept_language ~* 'zh'){   
        	set $language zh;
        }
        
        if ($http_accept_language ~* 'en'){
        	set $language en;
        }  
        
     	rewrite ^/$ http://www.myng.com/$language redirect;
        
}

#2: 根据用户来源终端设备跳转至不同站点或不同域名
		if ($http_user_agent  ~* "iphone|ipad|androaid"){
        	rewrite ^/$ http://www.myng.com/m;
        }
        
#3：传递跳转的uri
		if ($http_user_agent  ~* "iphone|ipad|androaid"){
        	return 302 http://www.myng.com$request_uri;  #将uri传递
        }

api地址跳转

复制代码 
#api.myng.com/bbb   www.myng.com/api/bbb

server {
	listen 80;
	server_name api.myng.com;
	if ($http_host ~* (.*)\.(.*)\.(.*)){
		set $domain $1;
	}
	rewrite ^/(.*)$  http://www.myng.com/$domain/$1 last;
}

维护页面

sh 复制代码 
server {
	listen 80;
	server_name www.myng.com.zh  www.myng.com.en;
	root /code;
	rewrite ^/(.*)$ /wh.html break; #放在server下
	
    location / {...

根据状态码跳转

sh 复制代码 
server {
	listen 80;
	server_name www.myng.com;
	root /code;
	index index.html;
...    
            error_page   500 502 503 504  =@temp;
	location @temp {
		root /data/error
		rewrite ^/(.*)$ /wh.html break; #放在server下	
	}

根据ip区分用户

sh 复制代码 
server {
	listen 80;
	server_name www.myng.com;
	root /code;
	set $ip 0;
	if ($remote_addr ~ "10.0.0.1") { #X-Forwarded-For代理ip
		set $ip 1;
    }
    if  ($ip=0){
    	rewrite  ^/(.*)$ /wh.html break; #放在server下
    }

return 返回跳转

sh 复制代码 
需求: 如果用户请求www.myng.com/test，则返回至ww.xuliangwei.com的url

server {
        listen 80;
        server_name www.myng.com;
        location / {
        
            default_type text/html;# 需要设置--》识别返回字符串
            if ($request_uri  ~* '^/test'){
                return 200 "return test";
                #return 302 http://www.baidu.com;   #302跳转到百度
            }

            root /code;
            index index.html;
        }
}


#浏览器访问：返回
http://www.myng.com/test     return test

last break

当rewrite规则遇到break后，本locationf与其他ocation的所有rewrite/return规则都不再执行。

当rewrite规则遇到last后，本locationh里后续rewrite/return规则不执行，但重写后的url再次从头开始执行所有规则，哪个匹配执行哪个

sh 复制代码 
server {
	listen 80;
	server_name www.myng.com;
	root /code;
	location / {
		#http://www.myng.com/1.html    b.html
		rewrite /1.html /2.html;
            #http://www.myng.com/1.html    2.html
            #rewrite /1.html /2.html break; #break终止，不再匹配
            #http://www.myng.com/1.html    a.html 
            #rewrite /1.html /2.html last; #last终止当前location的匹配
            
		rewrite /2.html /3.html;
	}
	
	location /2.html {
		rewrite /2.html /a.html;
	}
	
	location /3.html {
	rewrite /3.html /b.html;
	}
}
