axios发送请求，后端无法获取cookie

1.前端

axios默认不携带cookie

添加如下代码

import axios from "axios"
const requrst = axios.create({baseURL: import.meta.env.VITE_APP_URL,timeout: 5000,})
//让axios携带cookie
requrst.defaults.withCredentials = true

2.后端nestjs

main.ts

app.enableCors({//不用localhostorigin: 'http://127.0.0.1:5173', // 允许跨域源credentials: true,//允许携带methods: 'GET,HEAD,PUT,PATCH,POST,DELETE',})app.use(session({secret: 'yyds',name: "delicious",resave: false,saveUninitialized: false,cookie: { maxAge: 999999 }}))

在新建的user.controller.ts中

//发送验证码@Get('code')Code(@Req() req, @Res() res, @Session() session) {const CodeImg = svgCaptcha.create({size: 4,fontSize: 50,color: true,background: 'black',inverse: true,width: 100})//保存验证码session.code = CodeImg.textreq.session.delicious = "ddddd"// console.log(req.session)res.type('image/svg+xml')res.send(CodeImg.data)}//测试 
@Post()async create(@Body() body: User_add, @Res() res, @Session() session, @Req() req) {//不要用localhost，也不要写*res.setHeader("Access-Control-Allow-Origin", "http://127.0.0.1:5173");res.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE, HEAD,PUT");res.setHeader("Access-Control-Allow-Headers", "access-control-allow-origin, authority, content-type, version-info, X-Requested-With");//关键配置res.setHeader("Access-Control-Allow-Credentials", "true")console.log(req.session)res.send({ok: "ok"})}

主要的问题就是使用了localhost，而不是127.0.0.1，导致一直获取不到
