NestJs实现各种请求与参数解析

NestJs中的各种请求与携带参数的解析

demo.controller.ts

import { Body, Param, Controller, Delete, Get, Post, Patch } from '@nestjs/common';
import { DemoService } from './demo.service';
import { adduser, updateuser } from "./types/index"
@Controller('demo')
export class DemoController {
    constructor(private demoService: DemoService) {
    }
    // Get请求
    @Get("/getuserlist")
    getUserlist() {
        return this.demoService.getUserlist()
    }
    // Get请求携带Query参数
    @Get("/getuserlist/:name")
    getUserlistParam(@Param('name') name: string) {
        return this.demoService.getUserlistParam(name)
    }
    // Post请求
    @Post("/adduser")
    createUser(@Body() userdata: adduser) {
        return this.demoService.addUser(userdata.name)
    }
    // Delete请求
    @Delete("/deleteuser")
    deleteUser(@Body() name: adduser) {
        return this.demoService.deleteUser(name.name)
    }
    // Delete请求携带Query参数
    @Delete("/deleteuser/:name")
    deleteUserParam(@Param('name') name: string) {
        return this.demoService.deleteUserParam(name);
    }
    // Patch请求
    @Patch("/updateuser")
    updateUser(@Body() userdata: updateuser) {
        return this.demoService.updateUser(userdata.NewName, userdata.OldName)
    }
}

demo.service.ts

import { Injectable } from '@nestjs/common';
@Injectable()
export class DemoService {
    getUserlist() {
        return ["John", "Jane", "Bob"];
    }
    getUserlistParam(username: string) {
        return `User ${username} found`;
    }
    addUser(user: string) {
        return `User ${user} added successfully`;
    }
    deleteUser(user: string) {
        return `User ${user} deleted successfully`;
    }
    updateUser(user: string, newUser: string) {
        return `User ${user} updated to ${newUser} successfully`;
    }
    deleteUserParam(username: string) {
        return `User ${username} deleted successfully`;
    }
}
