连接MongoDb(Mongooes)

安装

npm i @nestjs/mongoose mongoose

配置

import { Module } from '@nestjs/common'
import { AppController } from './app.controller'
import { MongooseModule } from '@nestjs/mongoose'
import { AppService } from './app.service'
@Module({
  imports: [MongooseModule.forRoot(`mongodb://47.92.214.203/jiamei`)],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}

模型注入

import { Prop, Schema, SchemaFactory } from '@nestjs/mongoose'
import { HydratedDocument } from 'mongoose'

export type CatDocument = HydratedDocument<App>

@Schema()
export class App {
  @Prop()
  userName: string

  @Prop()
  passWord: string

  @Prop()
  isActive: string
}

export const AppSchema = SchemaFactory.createForClass(App)

使用

app.module.ts

import { Module } from '@nestjs/common'
import { AppController } from './app.controller'
import { MongooseModule } from '@nestjs/mongoose'
import { AppService } from './app.service'
import { App, AppSchema } from './app.entity'

@Module({
  imports: [
    MongooseModule.forRoot(`mongodb://47.92.214.203/jiamei`),
    MongooseModule.forFeature([{ name: App.name, schema: AppSchema }]),
  ],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}

app.controller.ts

import { Controller, Get } from '@nestjs/common'
import { AppService } from './app.service'

@Controller()
export class AppController {
  constructor(private readonly appService: AppService) {}

  @Get('register')
  register() {
    return this.appService.register()
  }
}

app.service.ts

import { Injectable } from '@nestjs/common'
import { App } from './app.entity'
import { InjectModel } from '@nestjs/mongoose'
import { Model } from 'mongoose'
@Injectable()
export class AppService {
  constructor(@InjectModel(App.name) private readonly app: Model<App>) {}
  async register() {
    const createdUser = new this.app({
      userName: 'admin',
      passWord: '123456',
      isActive: false,
    })
    const data = await createdUser.save()
    return {
      code: 200,
      msg: '注册成功',
      result: data,
    }
  }
}
