这个项目演示了如何使用OpenResty和Moochine开发Web应用。
Get Docker image and run:
docker pull kdr2/debian:sid-moochine
# run in attached docker container shell:
$ docker run -t -i -p 0.0.0.0:9801:9800 kdr2/debian:sid-moochine /bin/bash
root@4df89d75e286:/# /root/moochine-demo/bin/start.sh
# or in a detached dcoker container:
$ docker run -d -p 0.0.0.0:9801:9800 kdr2/debian:sid-moochine /root/moochine-demo/bin/start.sh -f
Then visit http://localhost:9801/ltp with you browser. More details: https://registry.hub.docker.com/u/kdr2/debian/
参看:http://openresty.org/#Installation
编译时选择luajit, ./configure --with-luajit
#Checkout Moochine 代码
git clone git://github.com/appwilldev/moochine.git
#设置OpenResty环境变量
export OPENRESTY_HOME=/usr/local/openresty
#设置Moochine环境变量
export MOOCHINE_HOME=/path/to/moochine
#将以上两个环境变量 加到 ~/.bash_profile 里,下次登陆自动生效
vim ~/.bash_profile
#使环境变量立即生效
source ~/.bash_profile
git clone git://github.com/appwilldev/moochine-demo.git

请求处理函数接收2个参数,request和response,分别对应HTTP的request和response。从request对象拿到客户端发送过来的数据,通过response对象返回数据。request和response对象也可以通过ngx.ctx.request, ngx.ctx.response来获取。

tail -f nginx_runtime/logs/error.log #查看 Nginx 错误日志和调试日志 的输出
- MOOCHINE URL Mapping Error
- Error while doing defers
- Moochine ERROR
多个 moochine-app 可以运行与同一nginx进程中,只要将本例子中nginx.conf内moochine-app相关段配置多份即可。
某moochine-app可以作为另一app的sub-app运行,在主app的application.lua内配置:
subapps={
subapp1 = {path="/path/to/subapp1", config={}},
...
}
