1、下载

npm i --save @nestjs/axios axios

2、全局配置

import { HttpModule } from '@nestjs/axios';@Global()
@Module({imports: [HttpModule.registerAsync({inject: [ConfigService],useFactory: async (configService: ConfigService) => {return {timeout: configService.get('http.timeout'),maxRedirects: configService.get('http.maxRedirects'),};},}),],exports: [HttpModule],
})

全部全局模块如下

import { Global, Module } from '@nestjs/common';
import { ConfigModule, ConfigService } from '@nestjs/config';
import { HttpModule } from '@nestjs/axios';
import { TypeOrmModule, TypeOrmModuleOptions } from '@nestjs/typeorm';
import configuration from '../../config/index';
import { JwtModule } from '@nestjs/jwt';
import { APP_FILTER, APP_GUARD, APP_INTERCEPTOR } from '@nestjs/core';
import { JwtGuard } from 'src/utils/jwt/jwt-guard';
import { JwtStrategy } from 'src/utils/jwt/jwt-strategy';
import { WinstonService } from 'src/utils/logger/winston-service';
import { CatchLoggerFilter } from 'src/utils/logger/catch-logger-filter';
import { ResponseLoggerInterceptor } from 'src/utils/logger/response-logger-interceptor';
import { RedisModule } from '@nestjs-modules/ioredis';
import { RequirePermissionGuard } from 'src/utils/premission/require-premission.guard';
@Global()
@Module({imports: [ConfigModule.forRoot({isGlobal: true,load: [configuration],}),TypeOrmModule.forRootAsync({name:"default",inject: [ConfigService],useFactory: (configService: ConfigService) => {return {type: 'mysql',...configService.get('db.mysql'),timezone: '+08:00',// logger: 'advanced-console',entities: [__dirname + '/../**/*.entity.{js,ts}'],} as TypeOrmModuleOptions;},}),TypeOrmModule.forRootAsync({name: "oracle",inject: [ConfigService],useFactory: async (configService: ConfigService) => {return {type: 'oracle',...configService.get('db.oracle'),// logger: 'advanced-console',timezone: '+08:00',entities: [__dirname + '/../**/*.entity.{js,ts}'],} as TypeOrmModuleOptions;},}),HttpModule.registerAsync({inject: [ConfigService],useFactory: async (configService: ConfigService) => {return {timeout: configService.get('http.timeout'),maxRedirects: configService.get('http.maxRedirects'),};},}),RedisModule.forRootAsync({inject: [ConfigService],useFactory: (configService: ConfigService) => {return {type: "single",url: configService.get('redis.url'),};},}),JwtModule.registerAsync({inject: [ConfigService],global: true,useFactory: (configService: ConfigService) => {return {secret: configService.get('jwt.secretkey'),// signOptions: { expiresIn: configService.get('jwt.expiresin') },};},})],providers: [JwtStrategy,{provide: APP_GUARD,useFactory: (configService: ConfigService) => {return new JwtGuard(configService);},inject: [ConfigService],},{provide: APP_GUARD,useClass: RequirePermissionGuard},{provide: WinstonService,inject: [ConfigService],useFactory: (configService: ConfigService) => {return new WinstonService(configService);}},{provide: APP_FILTER,useClass: CatchLoggerFilter},{provide: APP_INTERCEPTOR,useClass: ResponseLoggerInterceptor}],exports: [WinstonService,HttpModule],
})
export class ShareModule { }

3、使用

import { Injectable } from "@nestjs/common";
import { HttpService } from "@nestjs/axios";
import { firstValueFrom } from "rxjs";@Injectable()
export class TestService {constructor(private readonly httpService: HttpService,) { }async getTest() {const observable = this.httpService.get('https://api.github.com/users/yangxiaodong');// 请求成功后使用firstValueFrom方法获取结果const response = await firstValueFrom(observable);return response.data}
}
