Vue2.0+Node.js+MongoDB全栈打造商城系统（第10章）
第10章 登录模块实现
10-1 登录功能实现
ImoocMall/config/index.js中添加代理：
proxyTable: {
'/goods': {
target: 'http://localhost:3000'
},
'/goods/*':{
target:'http://localhost:3000'
},
'/users/*':{
target:'http://localhost:3000'
}
},
ImoocMall/server/routes/users.js登录接口:
var express = require('express');
var router = express.Router();
var User = require("./../models/user") //获取模型
/* GET users listing. */
router.get('/', function(req, res, next) {
res.send('respond with a resource');
});
//登录接口
router.post("/login", function (req,res,next) {
var param = {
userName:req.body.userName,
userPwd:req.body.userPwd
}
User.findOne(param, function (err,doc) {
if(err){
res.json({
status:"1",
msg:err.message
});
}else{
if(doc){
res.cookie("userId",doc.userId,{
path:'/',
maxAge:1000*60*60
});
res.json({
status:'0',
msg:'',
result:{
userName:doc.userName
}
});
}
}
});
});
module.exports = router;

ImoocMall/server/routes/goods.js修改：
-
router.get("/",function (req,res,next) {改成
router.get("/list",function (req,res,next) {
(一级路由改成二级路由。方便req.originalUrl.indexOf('/goods/list')>-1拦截)
ImoocMall/src/views/GoodsList.vue修改:
-
axios.get("/goods",{
改成axios.get("/goods/list",{
ImoocMall/src/views/NavHeader.vue新增检查跟新方法：
