前端代码：
<li v-for="(itme,index) in GoodList">
<div class="pic">
<a href="#"><img v-lazy="'/static/'+itme.productImage" alt=""></a>
</div>
<div class="main">
<div class="name">{{itme.productName}}</div>
<div class="price">{{itme.salePrice}}</div>
<div class="btn-area">
<a href="javascript:;" class="btn btn--m" @click="addCart(itme.productId)">加入购物车</a>
</div>
</div>
</li>
addCart(productId){
axios.post('/goods/addCart',{productId:productId}).then((res)=>{
if(res.status==0){
alert("添加成功");
}else{
alert("msg:"+res.msg);
}
})后端代码：
///加入购物车
router.post("/addCart", function(req, res, next) {
var userId = "100000077";
var productId = req.body.productId;
var User = require('../models/user');
User.findOne({
userId: userId
}, function(err, userDoc) {
if(err) {
res.json({
status: "1",
msg: err.message
})
} else {
if(userDoc) {
console.log("userDoc:" + userDoc);
let goodsItem = '';
userDoc.cartList.forEach(function(item) {
if(item.productId == productId) {
goodsItem = item;
item.productNum++;
}
});
if(goodsItem) {
userDoc.save(function(err2, doc2) {
if(err2) {
res.json({
status: "1",
msg: err2.message
});
} else {
res.json({
status: "0",
msg: "",
result: "suc"
});
}
})
} else {
Goods.findOne({
productId: productId
}, function(err1, doc) {
if(err1) {
res.json({
status: "1",
msg: err1.message
});
} else {
if(doc) {
newobj = { //新创建一个对象，实现转换mongoose不能直接增加属性的坑
productId: doc.productId,

checked: "1",
}
userDoc.cartList.push(newobj);
