express 搭建脚手架 - 因为chroma网络设置开了代理导致无法显示页面。。。。。。。。
express & nodejs 设置路由获取mongodb的里面的数据：
数据请求页面设置：
var express = require('express');
var router = express.Router();
let mongodb = require('mongodb'); //mongodb == 对象
const MongoClient = require('mongodb').MongoClient; //链接对象
let url = 'mongodb://localhost:27017';
router.get('/', function(req, res, next) {
MongoClient.connect(url, function(err, client) {
const db = client.db('guazi'); //db==库
const product = db.collection('product');
let start = req.query.start - 0;
let count = req.query.count - 0;
product.find({}, { limit: count, skip: count * (start - 1) }).toArray((err, data) => {
if (err) {
res.send({ "error": 1, "message": "库操作错误", "data": null })
} else {
// console.log(data)
res.send({ "error": 0, "message": "成功", "data": data });
}
})
client.close();
});
});
module.exports = router;
