如何更改中间件node.js中的响应头
我在谷歌上搜索了很多这个问题，但不幸的是，所有的解决方案都不适合我 我需要向响应头isAuth添加特殊属性，该属性必须为true。我试着使用set、setHeader、append等。但所有这些方法对我都不起作用 我的中间件：如何更改中间件node.js中的响应头,node.js,typescript,express,middleware,Node.js,Typescript,Express,Middleware,我在谷歌上搜索了很多这个问题，但不幸的是，所有的解决方案都不适合我 我需要向响应头isAuth添加特殊属性，该属性必须为true。我试着使用set、setHeader、append等。但所有这些方法对我都不起作用 我的中间件： export const isAuthenticated = async (req, res, next) => { res.set('isAuth', true); next(); } 我的控制器，我想在其中读取此标头属性isAuth: impo
export const isAuthenticated = async (req, res, next) => {
res.set('isAuth', true);
next();
}
import httpStatus from 'http-status';
import { RequestHandler } from 'express';
export const controller: RequestHandler = async (req: Request<ParamsDictionary, any, any, QueryString.ParsedQs>, res: Response<any>) => {

console.log('isAuth: ', isAuth)

从“http状态”导入httpStatus；
从“express”导入{RequestHandler}；
export-const-controller:RequestHandler=async（请求：请求，回复：响应）=>{
