koatty middleware test

• 4.Create a Model

//default use thinkorm
koatty model test


//use typeorm
koatty model -o typeorm test

• 5.Create a Aspect

定义切面类:

koatty aspect test

使用切面：

@Controller()
@BeforeEach("TestAspect")  //类的每一个方法执行之前执行
export class TestController extends BaseController {
    app: App;

    @RequestMapping("/test", RequestMethod.ALL)
    @After("TestAspect") //test方法执行之前执行
    async test() {
        const info = await this.testService.test();
        return this.body(info);

    age: number;
}

使用实体类进行验证：

@Controller()
export class TestController extends BaseController {
    app: App;

    @RequestMapping("/test", RequestMethod.ALL)
    @Validated() // <== 开启验证   
    async test(@Get() param: TestDTO) { // <== 指定DTO
