Management system itclub (Part 1)

Management system -ITclub（ On ）

author ： Xianda egg

The goal is ： Complete the project

describe ：ITclub It is a platform for programmers to share life dynamics

1. Initialize project

First step ： Let the project run first

• Successful launch

  

2. Project directory structure

├── src                        #  Source code 
│   ├── router                 #  route 
│   ├── utils                  #  Tool method 
│   ├── conctroller       #  All controller methods 
│   ├── service              #  Database operations

│   ├── main.js                #  Entrance file   Load components   Initialization etc. 
├── postcss.config.js          # postcss  To configure 
└── package.json               # package.json

3. Project structures,

The application configuration information is written to the environment variable

① To write .env file

② adopt doenv Load the configured environment variables

③ Writing configuration files

Complete the project initialization （2022-05-23）

4. User registration interface

Writing process ：

• Register user routes router To write ;
• The controller that handles the function controller To write ;
• Operating the database service To write ;

Be careful ： Need to install koa Yes body Dependency resolution

// Catalog ：./src/app/index.js
const Koa = require("koa")
const bodyParser = require("koa-bodyparser")

const userRouter = require('../router/user_router')

const app = new Koa()

app.use(bodyParser())
app.use(userRouter.routes())
app.use(userRouter.allowedMethods())

module.exports = app

Database connection operation （mysql2）

① install mysql2

② Connect to database

ps: The environment variables here need to be in .env Fill in the environment configuration file

Registered user verification

① Write user information to the database

#  Create a user table 
CREATE TABLE IF NOT EXISTS `user`(
	id INT PRIMARY KEY AUTO_INCREMENT,
	name VARCHAR(30) NOT NULL UNIQUE,
	password VARCHAR(50) NOT NULL,
	createAt TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
	updateAt TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);

• Insert the success

② Verify user , Create middleware verifyUser（./src/middleware/user_middleware）

③ Verify whether the user has registered

Password encrypted storage

Block the password registered by the user and encrypt it , And then stored in the database , Prevent database leaks , Here the MD5 encryption

① establish handlePassword function

② stay utils Create under directory password_handle.js

Complete the user registration interface （2022-05-24）

5. User login interface

Writing process

• to grant authorization router Compiling

• Dealing with functions contrler To write

Verification middleware （verifyLogin）

• Whether the account and password are empty

• Whether the user name exists

• Verify that the passwords are consistent

• To complete the verification

Supplementary treatment （index.js) Route introduction encapsulation in

Successful login returns credentials

Be careful ： Add here cookie and token Knowledge about http://t.csdn.cn/u4tO1

introduce keys（ Reference resources http://t.csdn.cn/u4tO1 ）–> Write the public and private keys to the configuration file （src/app/config.js）

Dispatch token and verification token

① Write verification test interface

√ Complete the user interface design （20222-5-27）
