Nginx中proxy_pass 的 斜槓解析問題

server {
   listen       80;
   server_name  localhost;

   location /doc1/ {
           proxy_pass http://localhost:8080;
        }
   # http://localhost/doc1/xxx -> http://localhost:8080/doc1/xxx


   location /doc2/ {
           proxy_pass http://localhost:8080/;
        }
   # http://localhost/doc2/xxx -> http://localhost:8080/xxx


   location /doc3 {
           proxy_pass http://localhost:8080;
        }
   # http://localhost/doc3/xxx -> http://localhost:8080/doc3/xxx


   location /doc4 {
           proxy_pass http://localhost:8080/;
        }
   # http://localhost/doc4/xxx -> http://localhost:8080//xxx，請注意這裏的雙斜線，好好分析一下。


   location /doc5/ {
           proxy_pass http://localhost:8080/haha;
        }
   # http://localhost/doc5/xxx -> http://localhost:8080/hahaxxx，請注意這裏的haha和xxx之間沒有斜槓，分析一下原因。

   location /doc6/ {
           proxy_pass http://localhost:8080/haha/;
        }
   # http://localhost/doc6/xxx -> http://localhost:8080/haha/xxx

   location /doc7 {
           proxy_pass http://localhost:8080/haha;
        }
   # http://localhost/doc7/xxx -> http://localhost:8080/haha/xxx

   location /doc8 {
           proxy_pass http://localhost:8080/haha/;
        }
  # http://localhost/doc8/xxx -> http://localhost:8080/haha//xxx，請注意這裏的雙斜槓。
}

如果有二級文件夾，需要加上^~要注意

location ^~ /doc/ {}
