Detailed explanation of the automatic card purchase plan for WeChat mini program coupons
I hope to automatically add coupons to user card packages in the WeChat mini program, without jumping to the WeChat coupon collection page? This requires the cooperation of the backend. This article will elaborate on the implementation process.
User scenario: The mini program displays a coupon list. The user clicks to collect it without jumping. It directly prompts "received successfully". The coupon is automatically deposited into the WeChat card package. wx.addCard()
method will jump to the WeChat collection page, so it is not applicable.
Implementation steps:
The front-end of the mini program triggers the collection: After the user clicks to receive the coupon, the front-end of the mini program sends a collection request to the back-end server, including the coupon ID and user information.
Back-end server processing: The back-end server verifies the user's qualifications, records the collection information, and calls the WeChat Open Platform API, and uses code parameters to directly add the coupon to the user's card package. This step does not require front-end participation.
The backend returns the result: After the backend processing is completed, the success or failure information is returned to the frontend of the applet.
Tips for the front-end of the mini program: The front-end returns the result based on the back-end, and displays a prompt of "receiving successfully" or failure. The coupons have been automatically added to the user's WeChat card package by the backend ("I"-"Card Pack"-"Coupon and Gift Card").
The core lies in the backend using the WeChat API to add coupons, and the frontend is only responsible for requests and prompts to achieve a seamless collection experience.

Python and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.

JavaScript can be used for front-end and back-end development. The front-end enhances the user experience through DOM operations, and the back-end handles server tasks through Node.js. 1. Front-end example: Change the content of the web page text. 2. Backend example: Create a Node.js server.

Choosing Python or JavaScript should be based on career development, learning curve and ecosystem: 1) Career development: Python is suitable for data science and back-end development, while JavaScript is suitable for front-end and full-stack development. 2) Learning curve: Python syntax is concise and suitable for beginners; JavaScript syntax is flexible. 3) Ecosystem: Python has rich scientific computing libraries, and JavaScript has a powerful front-end framework.

The power of the JavaScript framework lies in simplifying development, improving user experience and application performance. When choosing a framework, consider: 1. Project size and complexity, 2. Team experience, 3. Ecosystem and community support.

Introduction I know you may find it strange, what exactly does JavaScript, C and browser have to do? They seem to be unrelated, but in fact, they play a very important role in modern web development. Today we will discuss the close connection between these three. Through this article, you will learn how JavaScript runs in the browser, the role of C in the browser engine, and how they work together to drive rendering and interaction of web pages. We all know the relationship between JavaScript and browser. JavaScript is the core language of front-end development. It runs directly in the browser, making web pages vivid and interesting. Have you ever wondered why JavaScr

Node.js excels at efficient I/O, largely thanks to streams. Streams process data incrementally, avoiding memory overload—ideal for large files, network tasks, and real-time applications. Combining streams with TypeScript's type safety creates a powe

The differences in performance and efficiency between Python and JavaScript are mainly reflected in: 1) As an interpreted language, Python runs slowly but has high development efficiency and is suitable for rapid prototype development; 2) JavaScript is limited to single thread in the browser, but multi-threading and asynchronous I/O can be used to improve performance in Node.js, and both have advantages in actual projects.
