Error handling Middleware

Define error handling middleware must use 4 parameters, otherwise it will be used as normal middleware

/* Error Handler */ application.use (function(err,req,res,next) {  console.error (err.stack);  Res.status. Send ("Code error, error message:<br/>" +Err.stack);}); /* 404 */ application.use (function(req,res,next) {  res.status (404). Send (" 404 pages were dug away by Martians ") ;

Create a file structure

Public folders (common), Controller folders (controllers), model folders (models), view folders (views), Static resource folders (statics)

Define configuration files and function files and load

Configuration file Common/config.js

/* * * Public configuration file */ module.exports={    db_host:' localhost ',    db_name:' blog ',    db_user: ' Root ',    db_pass:' root ',    db_pre:',    app_port:' 8888 '};

function File Common/functions.js

/** * Public Function file*/Module.exports={    /*Simulate PHP's date () function*/phpdate:function(formatstr,time) {varParammodel= ' Ymdhis '; if(!FORMATSTR) formatstr= "y-m-d h:i:s"; if(time) {Mydatetime=NewDate (time*1000); }Else{mydatetime=NewDate (); }        varStrtimearr=[Mydatetime.getfullyear (). ToString (), (Mydatetime.getmonth ()+1). ToString (), Mydatetime.getdate (). ToString (), Mydatetime.gethours (). ToString (), Myda        Tetime.getminutes (). ToString (), Mydatetime.getseconds (). ToString (),];  for(vari=0;i<strtimearr.length; i++) {Formatstr=Formatstr.replace (Parammodel.charat (i), strtimearr[i]); }        returnFormatstr; }};

Load public files, define resource files

/* load public files, define resource files */ Global. C=require ("./common/config"); global. F=require ("./common/functions"); Application.use (express.static (' public '));

Routing-level Middleware

The controller is divided into two groups home and admin

/* routing-level middleware */ application.use ('/', require ('./controller/home/index ')); Application.use ('/admin ', require ('./ Controller/admin/index '));
