Question

我遇到错误

错误TS1241：作为表达式调用时，无法解析方法装饰器的签名。”当我使用注释'@httpGet（'/ product'）

我导入了以下软件包：

"express": "^4.17.1",
"inversify": "^5.0.1",
"inversify-express-utils": "^6.3.2"

我的代码是：

import { controller, httpGet, request, response } from "inversify-express-utils";
import { Request, Response } from "express";

@controller("")
export class ProductController implements IProductController {

    @httpGet('/product')
    async get(@request() req: Request, @response() res: Response) {

        ....
    }
}

有人遇到过同样的问题吗？

控制器注释必须是路线的名称，get注释要求您指定查询参数，如果没有，则仅指定/。还可以尝试将interfaces.Controller用作基类。例如，尝试以下代码

import { interfaces, controller, httpGet, request, response } from "inversify-express-utils";
import { Request, Response } from "express";

@controller("/product")
export class ProductController implements interfaces.Controller {

    @httpGet('/')
    async get(@request() req: Request, @response() res: Response) { ... }

    @httpGet('/:productId')
    async get(@request() req: Request, @response() res: Response) { ... }
}

在节点Express中使用@httpGet批注时出错
