使用Nginx做代理的时候,可以简单的直接把请求原封不动的转发给下一个服务。
比如,访问abc.com/appv2/a/b.html, 要求转发到localhost:8088/appv2/a/b.html
简单配置如下:
upstream one {
server localhost:8088 weight=5;
}
server {
listen 80;
server_name abc.com;
access_log "pipe:rollback /data/log/nginx/access.log interval=1d baknum=7 maxsize=1G" main;
location / {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://one;
}
}
即,设置proxy_pass
即可。请求只会替换域名。
但很多时候,我们需要根据url的前缀转发到不同的服务。
比如
abc.com/user/profile.html转发到 用户服务localhost:8089/profile.html
abc.com/order/details.html转发到 订单服务 localhost:8090/details.html
即,url的前缀对下游的服务是不需要的,除非下游服务添加context-path, 但很多时候我们并不喜欢加这个。如果Nginx转发的时候,把这个前缀去掉就好了。
/
.server {
listen 80;
server_name abc.com;
access_log "pipe:rollback /data/log/nginx/access.log interval=1d baknum=7 maxsize=1G" main;
location ^~/user/ {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://user/;
}
location ^~/order/ {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://order/;
}
}
^~/user/
表示匹配前缀是user
的请求,proxy_pass的结尾有/
, 则会把/user/*
后面的路径直接拼接到后面,即移除user.
rewrite
upstream user {
server localhost:8089 weight=5;
}
upstream order {
server localhost:8090 weight=5;
}
server {
listen 80;
server_name abc.com;
access_log "pipe:rollback /data/log/nginx/access.log interval=1d baknum=7 maxsize=1G" main;
location ^~/user/ {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-NginX-Proxy true;
rewrite ^/user/(.*)$ /$1 break;
proxy_pass http://user;
}
location ^~/order/ {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-NginX-Proxy true;
rewrite ^/order/(.*)$ /$1 break;
proxy_pass http://order;
}
}
注意到proxy_pass结尾没有/
, rewrite
重写了url。
