nginx测试rewrite

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

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uriif ($http_user_agent  ~* "iphone|ipad|androaid"){return 302 http://www.myng.com$request_uri;  #将uri传递}

api地址跳转

#api.myng.com/bbb   www.myng.com/api/bbbserver {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

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

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

根据ip区分用户

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ipset $ip 1;}if  ($ip=0){rewrite  ^/(.*)$ /wh.html break; #放在server下}

return 返回跳转

需求: 如果用户请求www.myng.com/test，则返回至ww.xuliangwei.com的urlserver {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

server {listen 80;server_name www.myng.com;root /code;location / {#http://www.myng.com/1.html    b.htmlrewrite /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;}
