node.js - 使用 Typescript 的 Express.js 路由

Question

我想使用 Express.js使用 Typescript 来指定代码更加模块化/面向对象。

我想通过实现 IRoute 接口(interface)然后将新的 Route 添加到 app.use() 来实现 Route/Controller。

我面临的问题是每个操作(get、post、put、delete)本身都返回 IRoute 接口(interface)，我不确定要返回什么。回来 return <IRoute> this;在操作中不起作用。

typescript 编译器响应以下错误消息:

Class MessurmentsController incorrectly implements interface IRoute. Types of property all are incomatible. Type (req: Request, res: Response, next: Function) => void is not assignable to type (...handler: RequestHandler[]): IRoute. Types of parameters req and handler are incomatible. Type Request is not assignable to type RequestHandler.

/// <reference path="../../../typings/tsd.d.ts" />

import {IRoute, Request,Response}  from 'express';


export class MeasurementsController implements IRoute {
	path: string;
	stack: any;
	
	constructor(){
		this.path = "/api/measurements"
	}
	
	
	all(req: Request, res: Response, next: Function){
		res.send('');
        //return <IRoute> this;
	}
	
	get(req: Request, res: Response, next: Function){
		res.send('');
	}
	
	post(req: Request, res: Response, next: Function){
		res.send('');
	}
	
	put(req: Request, res: Response, next: Function){
		res.send('');
	}
	
	delete(req: Request, res: Response, next: Function){
		res.send('');
	}
	patch(req: Request, res: Response, next: Function){
		res.send('');
	}
	options(req: Request, res: Response, next: Function){
		res.send('');
	}
	head(req: Request, res: Response, next: Function){
		res.send('');
	}
}

d.ts中的Route定义为

    module e {
        interface IRoute {
            path: string;
            stack: any;
            all(...handler: RequestHandler[]): IRoute;
            get(...handler: RequestHandler[]): IRoute;
            post(...handler: RequestHandler[]): IRoute;
            put(...handler: RequestHandler[]): IRoute;
            delete(...handler: RequestHandler[]): IRoute;
            patch(...handler: RequestHandler[]): IRoute;
            options(...handler: RequestHandler[]): IRoute;
            head(...handler: RequestHandler[]): IRoute;
        }

知道我需要在操作中返回什么才能使它正常工作吗？

终于有了解决办法:

路由 Controller 允许使用方法创建 Controller 类作为处理请求的操作。您可以将路由 Controller 与 express.js 或 koa.js 一起使用。 https://github.com/pleerock/routing-controllers
