在nginx中配置proxy_pass時，如果是按照^~匹配路徑時,要注意proxy_pass后的url最后的/。當加上了/，相當于是絕對根路徑，則nginx不會把location中匹配的路徑部分代理走;如果沒有/，則會把匹配的路徑部分也給代理走。

比如下面設置：

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，如果請求的url是http://servername/wangshibo/test.html會被代理成http://js.test.com/test.html

而如果這么配置

location ^~ /wangshibo/{proxy_cache js_cache;proxy_set_header Host js.test.com;proxy_pass http://js.test.com;}

則請求的url是http://servername/wangshibo/test.html會被代理到http://js.test.com/wangshibo/test.html

當然，可以用如下的rewrite來實現/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;}

列舉下面一例

1）第一種配置

[root@BJLX_16_202_V vhosts]# cat ssl-wangshibo.confupstream at {  server 192.168.1.202:8080 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/wang.cer;    ssl_certificate_key ssl/wang.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;    }  }

訪問https://www.wangshibo.com/attendance/和http://192.168.1.202:8080/attendance結果是一致的。

2）第二種配置

[root@BJLX_16_202_V vhosts]# cat ssl-wangshibo.confupstream at {  server 192.168.1.202:8080 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/wang.cer;    ssl_certificate_key ssl/wang.key;    location / {  proxy_pass http://at/attendance/;                         //一定要加上"/"              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;    }  }

訪問https://www.wangshibo.com和http://192.168.1.202:8080/attendance結果是一致的。
