nginx配置正则验证

安装

npm install logregnginxconfig

配置

var  logregnginxconfig = require ('logregnginxconfig');

var logregnginxconfig = function (logFormat) {}

/* @Params: logFormat参数就是标准NGINX配置文件中对应log_format内容 通过logFormat.match() 提取实际配置部分; 优先提取多行NGINX配置 通过单引号提取实际KEY列表 */

if (logFormat == undefined || logFormat == null)
    return null;

示例

const logregnginxconfig = require('logregnginxconfig')//引入logregnginxconfig

const log_sample = `42.110.55.127 - - [17/Jan/2019:16:52:17 +0800] "GET /favicon.ico HTTP/1.1" 45.16.35.141 404 404 570 "http://example.com/" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36" 0.000 -`  //配置 日志样例

const log_format = `log_format main  '$remote_addr - $remote_user [$time_local] "$request" '
                 '$status $request_length '
                 '$status $body_bytes_sent "$http_referer" '
                 '"$http_user_agent"';`   //配置推荐的log_format日志格式
const result = logregnginxconfig(log_format)

const generateRegex = new RegExp(result.regex) //生成一个正则

console.log(result);

console.log(log_sample.match(generateRegex))//对正则进行macth操作，分割枚举

/*
console.log(result);运行生成的正则如下:
{ space_err: false,
  err_list: [],
  regex:
   '(\\S*)\\s*-\\s*(\\S*)\\s*\\[(\\d+/\\S+/\\d+:\\d+:\\d+:\\d+)\\s+\\S+\\]\\s*"(\\S+)\\s+(\\S+)\\s+\\S+"\\s*(\\S*)\\s*(\\S*)\\s*(\\S*)\\s*(\\S*)\\s*"(\\S*)"\\s*"([\\S ]*)".*',
  keys:
   [ 'remote_addr',
     'remote_user',
     'time_local',
     'request_method',
     'request_uri',
     'status',
     'request_length',
     'status',
     'body_bytes_sent',
     'http_referer',
     'http_user_agent' ] }

console.log(log_sample.match(generateRegex));代码运行结果如下:
