Nginx中proxy_pass的斜杠问题

转载自https://www.jianshu.com/p/c751250a5112

各种情况如下：

server {
  listen       80;
  server_name  localhost;

  location /api1/ {
    proxy_pass http://localhost:8080;
  }
  # http://localhost/api1/xxx -> http://localhost:8080/api1/xxx

  location /api2/ {
    proxy_pass http://localhost:8080/;
  }
  # http://localhost/api2/xxx -> http://localhost:8080/xxx

  location /api3 {
    proxy_pass http://localhost:8080;
  }
  # http://localhost/api3/xxx -> http://localhost:8080/api3/xxx

  location /api4 {
    proxy_pass http://localhost:8080/;
  }
  # http://localhost/api4/xxx -> http://localhost:8080//xxx，请注意这里的双斜线，好好分析一下。

  location /api5/ {
    proxy_pass http://localhost:8080/haha;
  }
  # http://localhost/api5/xxx -> http://localhost:8080/hahaxxx，请注意这里的haha和xxx之间没有斜杠，分析一下原因。

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

  location /api7 {
    proxy_pass http://localhost:8080/haha;
  }
  # http://localhost/api7/xxx -> http://localhost:8080/haha/xxx

  location /api8 {
    proxy_pass http://localhost:8080/haha/;
  }
  # http://localhost/api8/xxx -> http://localhost:8080/haha//xxx，请注意这里的双斜杠。
