@webantic/nginx-config-parser nodejs nginx conf 解析以及生成处理包试用

@webantic/nginx-config-parser 是一个基于nodejs 开发nginx 配置解析工具

参考使用

• demo.conf

upstream mydemoapp {

        # simple round-robin

        server app1:80;

        server app2:80;

        check interval=1000 rise=2 fall=5 timeout=1000 type=http;

        check_http_send "HEAD / HTTP/1.0\r\n\r\n";

        check_http_expect_alive http_2xx http_3xx;

}

server {

    listen       80;

    server_name  mydemoapp.com;

    location / {

        root   html;

        index  index.html index.htm;

        proxy_pass http://mydemoapp;

    }

    location /status {

        healthcheck_status;

    }

}

 

 

server {

    listen       443 http2;

    server_name  mydemoapp.com;

    ssl app/cer;

    location / {

        root   html;

        index  index.html index.htm;

        proxy_pass http://mydemoapp;

    }

    location /status {

        healthcheck_status;

    }

}

• app.js

var ConfigParser = require('@webantic/nginx-config-parser')

var parser = new ConfigParser()

 

// parse straight from file. by default, will try to resolve includes

var config = parser.readConfigFile('demo.conf')

 

// to keep deterministic behaviour, set parseIncludes = false in the options

var configWithoutIncludes = parser.readConfigFile('demo.conf', { parseIncludes: false })

 

// write direct to file (overwriting existing one)

// 读取写到其他地方，比如基于json的解析，然后写到一个s3 的挂载中

parser.writeConfigFile('mynginx.conf', config, true)

console.log(configWithoutIncludes.server)

 

// 基于json 的nginx 配置生成

var sampleConfig = {

    "upstream mydemoapp":{

        "server":[

            "app1:80",

            "app2:80"

        ],

        "check":"interval=1000 rise=2 fall=5 timeout=1000 type=http",

        "check_http_send":"\"HEAD / HTTP/1.0\\\\r\\n\\r\\n\"",

        "check_http_expect_alive":"http_2xx http_3xx"

    },

    "server":[

        {

            "listen":"80",

            "server_name":"mydemoapp.com",

            "location /":{

                "root":"html",

                "index":"index.html index.htm",

                "proxy_pass":"http://mydemoapp"

            },

            "location /status":{

                "healthcheck_status":""

            }

        },

        {

            "listen":"443 http2",

            "server_name":"mydemoapp.com",

            "ssl":"app/cer",

            "location /":{

                "root":"html",

                "index":"index.html index.htm",

                "proxy_pass":"http://mydemoapp"

            },

            "location /status":{

                "healthcheck_status":""

            }

        }

    ]

}

 

// to multi-line config string

var configString = parser.toConf(sampleConfig)

var configString2 = parser.parse(sampleConfig)

console.log("app:",configString)

console.log("app2:",configString2)

// and back again

var configJson = parser.toJSON(configString)

 

// shorthand (will change object --> string and string --> object)

parser.parse(configString)

 

console.log(JSON.stringify(config))

说明

目前关于nginx 解析方便的工具并不是很多（主要是nginx 配置并不是很复杂，我们基于模版引擎也可以解决）
@webantic/nginx-config-parser 是一个不错的选择，可以解决我们管理nginx 配置的一些问题，而且支持json 以及nginx 配置的模式
集成到我们的系统中是一个不错的选择
