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

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 { }

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();
  }
}

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
    }
  }
}
