如何在不覆盖 Express 中原始请求的情况下为 res.body 创建 TypeScript 类型注释？

Question

我可以像下面这样将 req.body 的类型设置为 PersoneModel。

import { Request, Response } from 'express';

router.post('/',(req: Request<{}, any, PersoneModel>, res: Response) => {
   // req.body is now PersoneModel
}

但是，我覆盖了原始请求，例如下面显示的P extends core.Params = core.ParamsDictionary。

interface Request<P extends core.Params = core.ParamsDictionary, ResBody = any, ReqBody = any, ReqQuery = core.Query> extends core.Request<P, ResBody, ReqBody, ReqQuery> { }

如何避免这种情况？

Answer 1

您可以像下面那样从 express-serve-static-core 导入 ParamsDictionary。

import { ParamsDictionary } from "express-serve-static-core";
import { Request, Response } from 'express';


router.post('/',(req: Request<ParamsDictionary, any, PersoneModel>, res: Response) => {
   // req.body is now PersoneModel
}
