自定义一个log4js的layout,在该layout中判断输出的内容

How to use

use

const LoggerContentFilter = require('log4js_content_filter');
const log4js = require('log4js');

//at first add filter case and layout name
LoggerContentFilter.addContentFilter("filter-content",function (msg) {
    if (msg.indexOf("法外狂徒张三") > -1) {
        return true;
    }
    return false;
});

log4js.configure({
    appenders: {
        stdout: {
            type: 'console',
            layout: {
                type: "filter-content",//new type addContentFilter function first argument
                useLayout:"Coloured"//logger output layout style :Basic, Coloured, Dummy, messagePassThrough

        },
    },
    categories: {
        default: { appenders: ['stdout'], level: 'debug' },
    },
