主要是基于java 开发一个简单的扩展，学习下流程

MyApp.java
package com.dalong;
import nginx.clojure.java.ArrayMap;
import nginx.clojure.java.NginxJavaRingHandler;
import java.io.IOException;
import java.util.Map;
import static nginx.clojure.MiniConstants.*;
public class MyApp implements NginxJavaRingHandler {@Override
public Object[] invoke(Map<String, Object> map) throws IOException {return new Object[] {NGX_HTTP_OK, //http status 200
ArrayMap.create(CONTENT_TYPE, "text/plain"), //headers map
"Hello, Java & Nginx!" //response body can be string, File or Array/Collection of string or File
};
}
}
运行
基于docker-compose
- docker-compose 文件
version: '3'
services:
app:
image: dalongrong/nginx-clojure-0.5.3:latest
volumes:
- ./nginx.conf:/usr/local/nginx/conf/nginx.conf
- ./appjars:/opt/appjars
ports:
- 80:80
- nginx.conf
###you can uncomment next two lines for easy debug
###Warning: if master_process is off, there will be only one nginx worker running. Only use it for debug propose.
#daemon off;
#master_process off;
user root;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {worker_connections 1024;
}
http {include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
#gzip on;
jvm_path auto;
### Set my app jars and resources, it must include nginx-clojure runtime jar,e.g. nginx-clojure-0.5.3.jar and
### for clojure user clojure runtime jar is also needed.
### See http://nginx-clojure.github.io/directives.html#jvm_classpath
# 添加自定义classpath
jvm_classpath "libs/*:jars/*:/opt/appjars/*";
###jvm heap memory
#jvm_options "-Xms1024m";
#jvm_options "-Xmx1024m";
#for enable java remote debug uncomment next two lines
#jvm_options "-Xdebug";
#jvm_options "-Xrunjdwp:server=y,transport=dt_socket,address=840#{pno},suspend=n";
###threads number for request handler thread pool on jvm, default is 0.
###check more details from
#jvm_workers 8;
server {listen 80;
server_name localhost;
location / {root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {root html;
}
# 自己开发的java 方法
location /dalongdemo {content_handler_type 'java';
content_handler_name 'com.dalong.MyApp';
}
location /clojure {handler_type 'clojure';
handler_code '
(fn[req]
{:status 200,
:headers {"content-type" "text/plain"},:body "Hello Clojure & Nginx!"
})
';
}
}
}
- 运行效果
说明
nginx-clojure 很不错，而且很强大，对于nginx 的扩展开发我们又多了一种可选的方法
