ajax+node+request爬取网络图片的实例(宅男福利)

const express = require("express");const morgan = require('morgan');const ejs = require('ejs');const path = require('path');const bodyParser = require('body-parser');const app = express();//logs info to serverapp.use(morgan('dev'));//post resolveapp.use(bodyParser.json());app.use(bodyParser.urlencoded({extended: false}));// view engine setupapp.engine('html', ejs.__express);app.set('views', path.join(__dirname, 'views'));app.set('view engine', 'html');//设置静态文件如：图片， CSS, JavaScript 等。app.use(bodyParser.json());app.use(bodyParser.urlencoded({extended: false}));app.use(express.static(path.join(__dirname, 'public')));/** reuire pages*/var index = require('./routes/index')/** render pages*/app.use('/', index);// catch 404 and forward to error handlerapp.use(function(req, res, next) {var err = new Error('Not Found');err.status = 404;next(err);});// error handlerapp.use(function(err, req, res, next) {// set locals, only providing error in developmentres.locals.message = err.message;res.locals.error = req.app.get('env') === 'development' ? err : {};// render the error pageres.status(err.status || 500);res.render('error', {"title": '404',"msg": '服务异常'});});module.exports = app;app.listen(3000,function(){console.log('http://127.0.0.1:3000')});

client.get(url,function(err, response, body) {　　if((typeof body)!="string"){　　　　body = JSON.stringify(body);　　}　　arr =body.match(reg);　　console.log(arr);　　//这里就是当前页面的路径以及页面上图片列表的数组，通过res.json发送到client；　　res.json({"url":url,"records":arr});});})
