- 一個(gè)種方案是proxy_pass后面加根路徑/.
- 另一種方案是使用rewrite
使用Nginx做代理的時(shí)候，可以簡(jiǎn)單的直接把請(qǐng)求原封不動(dòng)的轉(zhuǎn)發(fā)給下一個(gè)服務(wù)。
比如，訪問(wèn)abc.com/appv2/a/b.html, 要求轉(zhuǎn)發(fā)到localhost:8088/appv2/a/b.html
簡(jiǎn)單配置如下：
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，設(shè)置proxy_pass即可。請(qǐng)求只會(huì)替換域名。
但很多時(shí)候，我們需要根據(jù)url的前綴轉(zhuǎn)發(fā)到不同的服務(wù)。
比如
abc.com/user/profile.html轉(zhuǎn)發(fā)到 用戶服務(wù)localhost:8089/profile.html
abc.com/order/details.html轉(zhuǎn)發(fā)到 訂單服務(wù) localhost:8090/details.html
即，url的前綴對(duì)下游的服務(wù)是不需要的，除非下游服務(wù)添加context-path, 但很多時(shí)候我們并不喜歡加這個(gè)。如果Nginx轉(zhuǎn)發(fā)的時(shí)候，把這個(gè)前綴去掉就好了。
一個(gè)種方案是proxy_pass后面加根路徑/.
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/表示匹配前綴是user的請(qǐng)求，proxy_pass的結(jié)尾有/， 則會(huì)把/user/*后面的路徑直接拼接到后面，即移除user.
另一種方案是使用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結(jié)尾沒(méi)有/， rewrite重寫了url。
