1. Cause
I found an article on Rare Earth Nuggets [Written for my girlfriend, automatically push heart-warming messages every day] , and it is very interesting to automatically send messages every day on a regular basis. I just heard a colleague talk about using the nodejs framework to implement the front-end and back-end at the weekly meeting. Examination system, I also learned through Baidu that the nodejs back-end framework ranks as shown in the figure, so I decided to try a nestjs (nodejs framework ranks second) implementation.
2. Environmental preparation
Operating system: windows, Linux, MacOs
Operating environment: except Nodejs>=12 v13 version
3. Create nestjs project
Creating a new project is very simple using Nest CLI. After installing npm, you can use the following command to create a Nest project in your OS terminal:
$ npm i -g @nestjs/cli
$ nest new project-name
The project-name directory will be created, node_modules and some other boilerplate will be installed, and a src directory will be created containing several core files.
src
├── app.controller.spec.ts
├── app.controller.ts
├── app.module.ts
├── app.service.ts
└── main.ts
Here is a brief overview of these core documents:
main.ts contains an asynchronous function that is responsible for bootstrapping our application:
import {
NestFactory } from '@nestjs/core';
import {
AppModule } from './app.module';
async function bootstrap() {
const app = await NestFactory.create(AppModule);
await app.listen(3000);
}
bootstrap();
To create a Nest application instance, we use the NestFactory core class. NestFactory exposes some static methods for creating application instances. The create() method returns an object that implements the INestApplication interface. This object provides a set of methods available. In the main.ts example above, we just started the HTTP service and let the application wait for HTTP requests.
4. Controller
@Controller('ymn')
export class YmnController {
constructor(private ymnService: YmnService) {
}
@Get()
async send(@Res() response: Response) {
const result = await this.ymnService.sendOut();
response.status(HttpStatus.OK).send('ok');
}
}
5. Service service layer
// 时间处理
const moment = require('moment');
@Injectable()
export class YmnService {
constructor(
private configService: ConfigService,
private readonly httpService: HttpService,
) {
}
/**
* @method 发送模板消息给媳妇儿
* @returns any[]
*/
async sendOut(): Promise<any[]> {
const token = await this.getToken();
const data = await this.getTemplateData();
console.log(data);
// 模板消息接口文档
const users = this.configService.get('weixin.users');
const promise = users.map((id) => {
data.touser = id;
return this.toWechart(token, data);
});
const results = await Promise.all(promise);
return results;
}
/**
* @method 获取token
* @returns string token
*/
async getToken(): Promise<string> {
...
}
/**
* @method 组装模板消息数据
* @returns dataType 组装完的数据
*/
async getTemplateData(): Promise<dataType> {
...
}
/**
* @method 获取距离下次发工资还有多少天
* @returns number
*/
getWageDay(): number {
...
}
/**
* @method 获取距离下次结婚纪念日还有多少天
* @returns number
*/
getWeddingDay(): number {
...
}
/**

*/
getbirthday(): number {
...
}
/**

*/
getDatetime(): string {
...
}
/**

* @returns number
*/
getMarryYear(): number {
...
}
/**

* @returns number
*/
getLoveYear(): number {
...
}
/**

* @returns number
*/
getBirthYear(): number {
...
}
/**
* @method 获取天气

*/
async getWeather(): Promise<weatherType> {
...
}
/**

* @returns string
*/
async getOneSentence(): Promise<string> {
...
}
/**
* @method 获取相恋天数

async toWechart(token: string, data: dataType): Promise<any> {

}
}
1. Obtain Access token
/**
* @method 获取token
* @returns string token
*/
async getToken(): Promise<string> {
const grantType = this.configService.get('weixin.grant_type');
const appid = this.configService.get('weixin.appid');
const secret = this.configService.get('weixin.secret');
// 模板消息接口文档
const url = `https://api.weixin.qq.com/cgi-bin/token?grant_type=${
grantType}&appid=${
appid}&secret=${
secret}`;
const result = await firstValueFrom(this.httpService.get(url));
if (result.status === 200) return result.data.access_token as string;
else return '';
}
2. Assemble template message data
/**
* @method 组装模板消息数据
* @returns dataType 组装完的数据
*/
async getTemplateData(): Promise<dataType> {
// 判断所需模板
// 发工资模板 getWageDay === 0 wageDay
// 结婚纪念日模板 getWeddingDay === 0 weddingDay
// 生日模板 getbirthday === 0 birthday
// 正常模板 daily
const wageDay = this.getWageDay();
const weddingDay = this.getWeddingDay();
const birthday = this.getbirthday();
const data = {
topcolor: '#FF0000',
template_id: '',
data: {
},
touser: '',
};
// 发工资模板
if (!wageDay) {
data.template_id = this.configService.get('weixin.wage_day');
data.data = {
dateTime: {
value: this.getDatetime(),
color: '#cc33cc',
},
};
} else if (!weddingDay) {
// 结婚纪念日模板
data.template_id = this.configService.get('weixin.wedding_day');

// 获取天气
const getWeather = await this.getWeather();
// 获取每日一句
const message = await this.getOneSentence();
data.data = {

}
return data;
}
3. Get the number of days until the next salary payment
/**
* @method 获取距离下次发工资还有多少天
* @returns number
*/
getWageDay(): number {
const wageDay = this.configService.get('time.wage_day');
// 获取日期 day
// 如果在wage号之前或等于wage时，那么就用wage-day
// 如果在wage号之后，那么就用wage +（当前月总天数 - day）
// 当日日期day
const day = moment().date();
// 当月总天数
const nowDayTotal = moment().daysInMonth();
// // 下个月总天数
let resultDay = 0;
if (day <= wageDay) resultDay = wageDay - day;
else resultDay = wageDay + (nowDayTotal - day);
return resultDay;
}
4. Get the number of days until the next wedding anniversary

const mmdd = moment(weddingDay).format('-MM-DD');
// 获取当年
const y = moment().year();
// 获取今年结婚纪念日时间戳
const nowTimeNumber = moment(y + mmdd).valueOf();
// 判断今天的结婚纪念日有没有过，如果已经过去（now>nowTimeNumber），resultMarry日期为明年的结婚纪念日
// 如果还没到，则结束日期为今年的结婚纪念日
let resultMarry = nowTimeNumber;
if (now > nowTimeNumber) {

async getWeather(): Promise<weatherType> {
try {
const dataType = this.configService.get('weather.data_type');
const ak = this.configService.get('weather.ak');
const districtId = this.configService.get('weather.district_id');
// https://api.map.baidu.com/weather/v1/?district_id=130128&data_type=all&ak=bGjmaBLLzlBZXTiAkOwSqiVjftZlg17O
const url = `https://api.map.baidu.com/weather/v1/?district_id=${

}
7. Configuration file
Configuration method reference configuration
1. WeChat public account configuration
Because individuals can only apply for a subscription number, and the subscription number does not support sending template messages, so the WeChat public account used here for testing can be applied for with a WeChat account, free of registration, and scan the code to log in
No public account required, quick application for interface test account
Directly experience and test all advanced interfaces of the public platform
import {
registerAs } from '@nestjs/config';
export default registerAs('weixin', () => ({
grant_type: '*',
appid: '*',
secret: '*',
users: ['*'],// 用户的openid
wage_day: '*',// 工资日模板
wedding_day: '*',// 结婚纪念日模板
birthdate: '*',// 生日模板
daily: '*',// 普通模板
}));
2. Special time point settings
import {
registerAs } from '@nestjs/config';
// 时间
export default registerAs('time', () => ({
wage_day: 10, // 工资日
wedding_day: '*',// 结婚纪念日
birthdate: '*',// 生日阴历
love: '*',// 相爱日期
}));
3. Weather configuration
import {
registerAs } from '@nestjs/config';
export default registerAs('weather', () => ({
data_type: 'all',
ak: '*',
district_id: '110100',
}));
8. WeChat message template
This needs to be set up separately in the WeChat public platform test account mentioned above
The following is the template I use
1. Normal template
{
{
dateTime.DATA}}
今天是 我们相恋的第{
{
love.DATA}}天
距离上交工资还有{
{
wage.DATA}}天
距离你的生日还有{
{
birthday.DATA}}天
距离我们结婚纪念日还有{
{
marry.DATA}}天
今日天气 {
{
wea.DATA}}
当前温度 {
{
tem.DATA}}度
最高温度 {
{
tem1.DATA}}度
最低温度 {
{
tem2.DATA}}度
风向 {
{
win.DATA}}
风力等级 {
{
wind_class.DATA}}
每日一句
{
{
message.DATA}}
2. Salary template
{
{
dateTime.DATA}}
老婆大人，今天要发工资了，预计晚九点前会准时上交，记得查收！
3. Birthday template
{
{
dateTime.DATA}}
听说今天是你人生当中第 {
{
individual.DATA}} 个生日？天呐，
我差点忘记！因为岁月没有在你脸上留下任何痕迹。
尽管，日历告诉我：你又涨了一岁，但你还是那个天真可爱的小妖女，生日快乐!
4. Wedding anniversary
{
{
dateTime.DATA}}
今天是结婚{
{
anniversary.DATA}}周年纪念日,在一起{
{
year.DATA}}年了,
经历了风风雨雨,最终依然走在一起,很幸运,很幸福!我们的小家庭要一直幸福下去。
