App开发之服务器框架搭建-轻识

关于服务器，在原有express上稍加改动。

增加 conf目录，创建config.js

var logger = require('../utils/log4jsutil').logger(__dirname+'/config.js');var server = {        sms:'',//短信 ali 阿里 jpush 极光        push:true,//推送        validate:true,//验证码        mysqldb:'default',//'default' 默认 'docker'   阿里云'ali'         app_name:'phelper',}/** * http服务器 */server.http_post = 9201;/** * 匹配服务器 */server.socket_match_post = 9104;/** * 猜诗聊天服务器 */server.socket_gp_chats_post = 8888;
server.socket_guess_post = 9201;
server.debug = 'debug';server.ali = 'ali';server.tencent = 'tencent';
server.env = server.debug;// server.env = server.ali;// server.env = server.tencent;
if(server.env == server.ali){    server.sms = 'ali';    server.push = true;    server.validate = true;    server.mysqldb = 'ali';}else if(server.env == server.tencent){      server.sms = 'ali';    server.push = true;    server.validate = true;    server.mysqldb = 'tencent';  }else{    // server.sms = 'ali';}
//配置项module.exports = {    server,};

bin/www中稍加改动，使用配置文件中的端口

var server_conf = require('../conf/config').server;var http_post = server_conf.http_post;
/** * Get port from environment and store in Express. */
var port = normalizePort(process.env.PORT || http_post);

创建daos目录，用来存放数据库操作

创建push目录，用来存放推送

创建test目录，用来存放一些测试单元

创建utils，用来存放工具集

utils目录下，创建log4jsutil.js,封装日志工具类

/** * 日志工具 *  logger.trace('This is an index page! -- log4js'); *  logger.debug('This is an index page! -- log4js'); *  logger.info('This is an index page! -- log4js'); *  logger.warn('This is an index page! -- log4js'); *  logger.error('This is an index page! -- log4js'); *  logger.fatal('This is an index page! -- log4js'); */var log4js = require('log4js');const fs = require('fs');
levels = {    'trace': log4js.levels.TRACE,    'debug': log4js.levels.DEBUG,    'info': log4js.levels.INFO,    'warn': log4js.levels.WARN,    'error': log4js.levels.ERROR,    'fatal': log4js.levels.FATAL};
function judgePath(pathStr) {    if (!fs.existsSync(pathStr)) {        fs.mkdirSync(pathStr);        // console.log('createPath: ' + pathStr);    }}

log4js.configure({  // appenders:[  //   //控制台输出  //   {"type": "console"},  //   {type: 'dateFile',  //   //文件名为= filename + pattern, 设置为alwaysIncludePattern：true  //   filename: 'logs/', // 需要手动创建此文件夹  //   pattern: 'yyyy-MM-dd.log',  //   //包含模型  //   alwaysIncludePattern: true,  // }],  // replaceConsole: true // 替换 console.log  appenders: {    out: { type: 'stdout' },    file: {         type: 'dateFile',        //文件名为= filename + pattern, 设置为alwaysIncludePattern：true        filename: 'logs/phelper', // 需要手动创建此文件夹        pattern: 'yyyy-MM-dd.log',        //包含模型        alwaysIncludePattern: true,     }  },  categories: {    default: { appenders: ['out','file'], level: 'debug' }  }})
exports.logger = function (name, level) {    name = name.replace(process.cwd(),'');    var logger = log4js.getLogger(name);    //默认为debug权限及以上    logger.level = levels[level] || levels['debug'];    return logger;};
exports.use = function (app, level) {  //加载中间件    app.use(log4js.connectLogger(log4js.getLogger('logInfo'), {        level: levels[level] || levels['debug'],      //格式化http相关信息        format: ':method :url :status'    }));};

安装log4js

npm install log4js
