使用nginx做反向代理的时候，可以简单的直接把请求原封不动的转发给下一个服务。设置proxy_pass请求只会替换域名，如果要根据不同的url后缀来访问不同的服务，则需要通过如下方法：
方法一：加"/"**
server {
listen 8000;
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。
方法二：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;
}
}
proxy_pass结尾没有/， rewrite重写了url。
