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
