- 修改 /src/app.module.ts
import { Module } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import { ConfigModule } from '@nestjs/config';
import configuration from 'config/configuration';
// 環(huán)境變量加載
const envFilePath = ['env/.env'];
if (process.env.NODE_ENV) {
envFilePath.unshift(`env/.env.${process.env.NODE_ENV}`);
}
@Module({
imports: [
ConfigModule.forRoot({
load: [configuration],
envFilePath,
}),
],
controllers: [AppController],
providers: [AppService],
})
export class AppModule {}
main.ts 使用配置
const configService = app.get(ConfigService);
const value = configService.get('xxxx');
// 獲取環(huán)境變量
const dbUser = configService.get<string>('DATABASE_USER');
// 獲取自定義配置值
const dbHost = configService.get<string>('database.host');
import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import { ConfigService } from '@nestjs/config';
import { Logger } from '@nestjs/common';
import {
FastifyAdapter,
NestFastifyApplication,
} from '@nestjs/platform-fastify';
import { ConfigurationType } from 'config/configuration';
async function bootstrap() {
const app = await NestFactory.create<NestFastifyApplication>(
AppModule,
new FastifyAdapter(),

const configService = app.get(ConfigService<ConfigurationType>);
const PORT = configService.get('port');
const HOST = configService.get('host');
const PREFIX = `/${configService.get('prefix')}`;

`,
);
});
}
bootstrap();
services 使用配置
- module 引入-ConfigModule
imports: [SequelizeModule.forFeature([UserModel]), ConfigModule],
- 依賴(lài)注入
import { HttpService } from '@nestjs/axios';
import { HttpException, HttpStatus, Injectable } from '@nestjs/common';
import { ConfigService } from '@nestjs/config';
import { InjectModel } from '@nestjs/sequelize';
import { AppJobModel } from 'src/model/customer/app-job.model';

import { CONST_CONFIG } from 'src/utils/const-config';
@Injectable()
export class AppJobService extends IBaseService<AppJobModel> {
constructor(
@InjectModel(AppJobModel)
private appJobModel: typeof AppJobModel,
private readonly httpService: HttpService,
private configService: ConfigService,
) {
super();
}
/**
* 獲取java 任務(wù)信息
* @param jobId
*/
async queryJavaJob(jobId: string) {
const url = `${this.configService.get<string>(
CONST_CONFIG.JAVASERVERURL,
)}/app-web/marketing/bee/task?taskCode=${jobId}`;
return this.httpService.axiosRef
.get(url)
.then((res) => res.data)
.catch((error) => {
console.log(error);
throw new HttpException(error, HttpStatus.INTERNAL_SERVER_ERROR);
});
}
}
