nestjs 开发手册
安装
npm i -g @nestjs/cli
创建项目
nest new <project-name>
nestjs 开发依赖
orm - prisma
pnpm add prisma-binding @prisma/client
pnpm add -D prisma
mock 数据
pnpm add mockjs
pnpm add -D @types/mockjs
配置文件
pnpm add @nestjs/config
校验
pnpm add class-validator class-transformer
密码加密
bcrypt 依赖 python 环境
pnpm add bcrypt
或者下载 bcryptjs
pnpm add bcryptjs
pnpm add -D @types/bcryptjs
bcrypt 使用
使用 bcrypt 加密密码
import { hashSync } from "bcryptjs"
// hasnSync(要散列的值，加密等级)
// val ? hashSync(val) : val;
// 对比密码是否一致
jwt
pnpm add @nestjs/jwt
SECRET = 22222
import { JwtModule } from '@nestjs/jwt'
@Global()
@Module({
imports: [JwtModule.registerAsync({
useFactory() {
return {
secret: process.env.SECRET,
}
}
})],
providers: [],
exports: [JwtModule]
})
export class JwtModule {}
passport 验证
安装依赖
pnpm add @nestjs/passport passport passport-local passport-jwt
pnpm add -D @types/passport @types/passport-local @types/passport-jwt
使用
进行登录时的校验并颁发 token
import { PassportStrategy } from "@nestjs/passport"
import { compareSync } from "bcryptjs"
import { IStrategyOptions, Strategy } from "passport-local"
export class LocalStrategy extends PassportStrategy(Strategy, "local") {
// local为策略的名称，默认为passport-local ,-后面的local。可以自定义名称，自定义名称后，使用AuthGuard需要指定对应的名称
constructor(@InjectModel(User) private userModel: ReturnModelType<typeof User>) {
super({
usernameField: "username",
passwordField: "password",
} as IStrategyOptions)
}
// 策略执行
async validate(username: string, password: string) {
const user = await this.userModel.findOne({ username }).select("password")
// 用户不存在
if (!user) {
throw new BadRequestException("用户名不正确")
}
// 密码不存在
if (!compareSync(password, user.password)) {
throw new BadRequestException("密码错误")
}
return user
}
}
import { PassportStrategy } from "@nestjs/passport"
import { compareSync } from "bcryptjs"
import { ExtractJwt, Strategy, StrategyOptions } from "passport-jwt"
export class LocalStrategy extends PassportStrategy(Strategy, "jwt") {
// jwt为策略的名称，默认为passport-jwt ,-后面的jwt。可以自定义名称，自定义名称后，使用AuthGuard需要指定对应的名称
constructor(@InjectModel(User) private userModel: ReturnModelType<typeof User>) {
super({
jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
secretOrKey: process.env.SECRET,
} as StrategyOptions)
}
// 策略执行
async validate(id) {
return await this.userModel.findById(id)
}
}
export class LoginDto {
username: string
password: string
}
import { Module } from "@nestjs/common"
import { PassportModule } from "@nestjs/passport"
import { AuthController } from "./auth.controller"
import { JwtStrategy } from "./jwt.strategy"
import { LocalStrategy } from "./local.strategy"
@Module({
imports: [PassportModule],
controllers: [AuthController],
providers: [LocalStrategy, JwtStrategy],
})
export class AuthModule {}
import { Post, UseGuards } from "@nestjs/common"
import { AuthGuard } from "@nestjs/passport"
import { LoginDto } from "./login.dto.ts"
import { JwtService } from "/jwt.module"
export class AuthController {
constructor(private jwtService: JwtService) {}
@Post("login")
@UseGuards(AuthGuard("local"))
async login(@Body() dto: LoginDto, @Req() req) {
return {
token: this.jwtService.sign(String(req.user._id)),
}
}
@Post("user")
@UseGuards(AuthGuard("jwt"))
async user(@Req() req) {
return req.user
}
}
token 颁发
日期处理
pnpm add dayjs
swagger 集成
pnpm add
