ThinkPHP6 is a web application development framework based on PHP language. Its design concept is simple, elegant and practical. It is currently one of the most popular PHP frameworks in China. At the same time, WeChat public account development is also one of the more popular directions in the Internet field. This article will introduce how to use ThinkPHP6 to implement WeChat public account development.

1. Introduction to WeChat Public Platform

WeChat Public Platform is an interactive information dissemination service platform provided by WeChat for individuals, enterprises, governments and other institutions. These include WeChat public accounts and WeChat mini programs. WeChat public accounts are used to provide users with information services and interactive communication, and can be divided into subscription accounts, service accounts, enterprise accounts, certified media, government agencies, etc.; WeChat mini programs provide users with lightweight application services. Mini programs can be opened directly in WeChat without downloading and installation.

This article aims to introduce how to use the ThinkPHP6 framework to realize the development of WeChat public accounts and realize the basic functions of WeChat public accounts.

2. Preparation

Before you start writing code, you need to prepare the following elements:

1. The developer account of the WeChat official account. Developers need to register a developer account on the WeChat public platform and obtain two parameters, AppID and AppSecret, which will be used in subsequent development.
2. Preparation of server environment. Before developing a WeChat public account, you need to ensure that the server environment has been set up. The server needs to support PHP language, and MySQL or other supported database software needs to be installed.
3. Installation of ThinkPHP6 framework. Developing WeChat public accounts requires the use of the PHP framework. This article chooses to introduce the ThinkPHP6 framework, which is less difficult and widely used.

3. Configure the WeChat public account

1. Configure the server address in the WeChat public platform

In the WeChat public platform, you need Set the server address and forward the request from the WeChat server to the server you built. In subsequent code writing, you need to use the server address, Token and other parameters.

2. Configure routing

In the ThinkPHP6 framework, routing needs to be set up to forward different requests from the WeChat official account to different controllers and methods. Routing configuration can be set in the route.php file in the config directory.

3. Basic interface to implement the development of WeChat public accounts

Developing WeChat public accounts requires the implementation of the following basic interfaces:

(1) Receive the information sent by the WeChat server ask.
(2) Verify and process the received message.
(3) Return the processing results to the WeChat server.

The implementation of the basic interface needs to be carried out in the controller and processed separately according to the request type (GET or POST) sent by the WeChat server.

4. Implement the functions of WeChat public account development

After implementing the basic interface of WeChat public account, you can add functions to meet the needs of users according to business needs.

1. Custom menu

The custom menu is part of the WeChat official account function. It can display the list of functions provided by the official account to facilitate users to make choices. The custom menu needs to be implemented by sending an HTTP request to the WeChat server.

2. Message push and automatic reply

Message push and automatic reply are relatively common functions in the development of WeChat public accounts, which can automatically reply to corresponding information based on the user's behavior. The implementation of message push and automatic reply requires parsing and processing the messages sent by the WeChat server, and returning the processing results to the WeChat server.

3. Web page authorized login

Web page authorized login is a relatively advanced function in WeChat public account development. Users can authorize the official account to obtain the user's basic information by accessing the web page in WeChat. Web page authorization login requires first obtaining the user's authorization, and then obtaining the user's basic information through the user's authorization code.

5. Summary

This article introduces how to develop WeChat public accounts through the ThinkPHP6 framework, including the configuration, basic interface and function implementation of WeChat public accounts. Developers can develop WeChat public accounts according to the guidance in this article. Of course, in order to implement more complex functions, developers need to continue to learn and master more technical knowledge.
