UNC parse xtend routes end handle 輸出 數據流 加載中

app.js文件 搭建後自動生成的入口文件 var createError = require(‘http-errors‘); var express = require(‘express‘); var path = require(‘path‘); var cookieParser = require(‘cookie-parser‘); //cookie解析者解析cookie數據 //引入帶有cookie-parser這種叫做中間件 //express中間件（當獲取數據時對相應的數據流做預處理 ）

var logger = require(‘morgan‘); //logger代表著後臺輸出的一些數據

var indexRouter = require(‘./routes/index‘); var usersRouter = require(‘./routes/users‘);

var app = express();

// view engine setup //設置文件默認的路徑 app.set(‘views‘, path.join(__dirname, ‘views‘)); app.set(‘view engine‘, ‘ejs‘);//設置模板引擎ejs

app.use(logger(‘dev‘)); app.use(express.json()); app.use(express.urlencoded({ extended: false })); //use方法加載中間件 //post 把數據放在 body get把數據放在協議裏 app.use(cookieParser()); app.use(express.static(path.join(__dirname, ‘public‘)));

app.use(‘/‘, indexRouter); app.use(‘/users‘, usersRouter);

// catch 404 and forward to error handler app.use(function(req, res, next) { next(createError(404)); });

// error handler app.use(function(err, req, res, next) { // set locals, only providing error in development res.locals.message = err.message; res.locals.error = req.app.get(‘env‘) === ‘development‘ ? err : {};

// render the error page res.status(err.status || 500); res.render(‘error‘); });

module.exports = app;
