如何在不覆盖TypeScript中的原始请求类型的情况下为req.body进行req.body类型注释？

Question

我可以执行如下操作，将req.body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，我重写了原始请求类型，如下面所示的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> { }

我怎么才能避免这种情况？

Answer 1

您可以像下面这样从ParamsDictionary中导入express-serve-static-core。

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
}
