The more difficult part in this video is the implementation of the shopping cart:

) The user does not log in with the user name and password, adds the product, closes the browser and opens it again without logging in with the user name and password. Password question: Are the items in the shopping cart still there?

2) The user logs in with username and password, adds products, closes the browser and reopens it without logging in with username and password. Question: Are the products in the shopping cart still there?

3) The user logs in with username and password, adds products, closes the browser, then opens it again, logs in with username and password. Question: Are the items in the shopping cart still there?

4) The user logs in with username and password, adds products, closes the browser, opens the browser from his hometown, and logs in with username and password. Question: Are the items in the shopping cart still there?

The above four questions are all based on JD.com, so guess what the result is?
1) In
2) No more
3) In
4) In

If you can guess the answer, then you are really great, so about these four How is the point implemented? (If there are friends who don’t agree with it, you can try it with JD.com)
Let’s explain the principle of the shopping cart, and finally talk about the specific code implementation.
1) User If you add products without logging in, the products at this time are added to the browser's cookies, so when you visit again (without logging in), the products are still in the cookies, so the products in the shopping cart still exist.
2 ) The user logs in and adds products. At this time, both the products in the cookie and the products selected by the user will be added to the shopping cart, and then the products in the cookie will be deleted. So when the user visits again (without logging in), the shopping cart in the cookie will be The product has been deleted, so the product in the shopping cart is no longer there.
3) The user logs in and adds the product. At this time, the product is added to the database for persistent storage. Open the login username and password again. The user The selected product must still exist, so the products in the shopping cart still exist.
4) Reason 3)
