一、proxy_pass

  • Nginx proxy_pass 后面的url 加/与不加/的区别

[!TIP] 在nginx中配置proxy_pass时,当在后面的url加上了/,相当于是绝对根路径,则nginx不会把location中匹配的路径部分代理走;

如果没有/,则会把匹配的路径部分也给代理走

  • 第一种
location  /proxy/ {
    proxy_pass http://127.0.0.1:81/;
}
location  /proxy/ {
    proxy_pass http://127.0.0.1:81/;
}

💡 说明

会被代理到 http://127.0.0.1:81/test.html 这个url

  • 第二(相对于第一种,最后少一个 / ) (proxy_pass 参数中如果不包含url的路径,则会将location的pattern识别的路径作为绝对路径
location  /proxy/ {
    proxy_pass http://127.0.0.1:81;
}
location  /proxy/ {
    proxy_pass http://127.0.0.1:81;
}

💡 说明

会被代理到 http://127.0.0.1:81/proxy/test.html 这个url

  • 第三种
location  /proxy/ {
    proxy_pass http://127.0.0.1:81/ftlynx/;
}
location  /proxy/ {
    proxy_pass http://127.0.0.1:81/ftlynx/;
}

💡 说明

会被代理到 http://127.0.0.1:81/ftlynx/test.html 这个url

  • 第四种情况(相对于第三种,最后少一个 / )
location  /proxy/ {
    proxy_pass http://127.0.0.1:81/ftlynx;
}
location  /proxy/ {
    proxy_pass http://127.0.0.1:81/ftlynx;
}

💡 说明

会被代理到 http://127.0.0.1:81/ftlynxtest.html 这个url
