nginx location 目錄匹配詳解

nginx location 加不加 / 匹配原則

nginx每個location都是一個匹配目錄，nginx的策略是：訪問請求來時，會對訪問地址進行解析，從上到下逐個匹配，匹配上就執行對應location大括號中的策略，並根據策略對請求作出相應。

server {   
  listen       80;   
  server_name  localhost;   # http://localhost/wddd01/xxx -> http://localhost:8080/wddd01/xxx

  location /wddd01/ {           
    proxy_pass http://localhost:8080;   
  }

  # http://localhost/wddd02/xxx -> http://localhost:8080/xxx   
  location /wddd02/ {           
    proxy_pass http://localhost:8080/;    
  }

  # http://localhost/wddd03/xxx -> http://localhost:8080/wddd03*/xxx   
  location /wddd03 {           
    proxy_pass http://localhost:8080;   
  }

  # http://localhost/wddd04/xxx -> http://localhost:8080//xxx，請注意這里的雙斜線，好好分析一下。
  location /wddd04 {           
    proxy_pass http://localhost:8080/;   
  }

  # http://localhost/wddd05/xxx -> http://localhost:8080/hahaxxx，請注意這里的haha和xxx之間沒有斜杠，分析一下原因。
  location /wddd05/ {           
    proxy_pass http://localhost:8080/haha;    
  }

  # http://localhost/api6/xxx -> http://localhost:8080/haha/xxx   
  location /wddd06/ {           
    proxy_pass http://localhost:8080/haha/;   
  }

  # http://localhost/wddd07/xxx -> http://localhost:8080/haha/xxx   
  location /wddd07 {           
    proxy_pass http://localhost:8080/haha;   
  } 
        
  # http://localhost/wddd08/xxx -> http://localhost:8080/haha//xxx，請注意這里的雙斜杠。
  location /wddd08 {           
    proxy_pass http://localhost:8080/haha/;   
  }
}

location目錄后加"/",只能匹配目錄，不加“/”不僅可以匹配目錄還對目錄進行模糊匹配。而proxy_pass無論加不加“/”,代理跳轉地址都直接拼接。
