proxy_pass根据path路径转发时的"/"问题记录

在nginx中配置proxy_pass时，如果是按照^~匹配路径时,要注意proxy_pass后的url最后的/。当加上了/，相当于是绝对根路径，则nginx不会把location中匹配的路径部分代理走;如果没有/，则会把匹配的路径部分也给代理走。

比如下面设置：
location ^~ /wangshibo/ 
{ 
proxy_cache js_cache; 
proxy_set_header Host js.test.com; 
proxy_pass http://js.test.com/; 
}
如上面的配置，如果请求的url是http://servername/wangshibo/test.html会被代理成http://js.test.com/test.html

而如果这么配置
location ^~ /wangshibo/ 
{ 
proxy_cache js_cache; 
proxy_set_header Host js.test.com; 
proxy_pass http://js.test.com; 
}
则请求的url是http://servername/wangshibo/test.html会被代理到http://js.test.com/wangshibo/test.html

当然，可以用如下的rewrite来实现/的功能
location ^~ /wangshibo/ 
{ 
proxy_cache js_cache; 
proxy_set_header Host js.test.com; 
rewrite /wangshibo/(.+)$ /$1 break; 
proxy_pass http://js.test.com; 
}

-----------------------------------------------------看看下面的实例--------------------------------------------------------------

1）第一种配置
[root@BJLX_16_202_V vhosts]# cat ssl-wangshibo.conf
upstream at {
    server 172.29.16.202:8080 max_fails=3 fail_timeout=30s;
}
 
server {
   listen 443;
   server_name www.wangshibo.com;
   ssl on;
 
   ### SSL log files ###
   access_log logs/wangshibo_access.log;
   error_log logs/wangshibo_error.log;
 
### SSL cert files ###
   ssl_certificate ssl/bkjk.cer;     
   ssl_certificate_key ssl/bkjk.key;  
 
   location /attendance/ {
   proxy_pass http://at;                                                          //不需要加上"/"                      
   proxy_next_upstream error timeout invalid_header http_500 http_502 http_503;
   proxy_set_header Host $host;
   proxy_set_header X-Real-IP $remote_addr;
   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
   proxy_set_header X-Forwarded-Proto https;
   proxy_redirect off;
       }
 
}
 
访问https://www.wangshibo.com/attendance/和http://172.29.16.202:8080/attendance结果是一致的。
