Nginx中proxy_pass里斜杠的问题总结

在使用 Nginx 做反向代理时，路径中结尾的斜杠会影响最终的效果，这里总结了一下各种带/和不带/的区别

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。
