{
"comments": [
{ "id": 1, "body": "some comment", "postId": 1 }
]
}
启动模拟api服务
./a-server.sh
./b-server.sh
配置Nginx为API网关
vim /etc/nginx/conf.d/a.conf
a.conf参考代码
server {
listen 80;
server_name 192.168.1.6;
location / {
proxy_pass http://192.168.1.6:3000/;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
}
location /aaa/ {
proxy_pass http://192.168.1.6:3000/;
}
location /bbb/ {
proxy_pass http://192.168.1.6:3001/;
