前言

在客户端使用Nuxt的useFetch调用接口并存储cookie，发现一些趣事~

cookie存储需要遵守同源策略~ 理论我们是知道的，但具体是怎么一回事呢~

实现

在Nuxt中是这样的~

直接访问

Nuxt

<template><div>{{ data }}</div>
</template><script setup lang="ts">
const { data } = await useFetch('http://localhost:9090/getUserInfo', {method: "POST",body: {name: "xxx"},server: false,})</script>

Express

const express = require("express")
const cookieParser = require("cookie-parser")
const cors = require("cors");
const app = express()
const PORT = 9090app.use(cors());
app.use(cookieParser())
app.use(express.json())
app.use(express.urlencoded({ extended: true }))app.post('/getUserInfo', (req, res) => {const { name } = req.bodyres.cookie('name', '张三', { httpOnly: true })res.send({text: `哎呀 ${name}你干嘛~`})
})app.listen(PORT, () => {console.log(`listening on ${PORT}`);
})

效果 

 直接访问是存储不了cookie，因为不同源~

代理

Nuxt

<template><div>{{ data }}</div>
</template><script setup lang="ts">
const { data } = await useFetch('/api/getUserInfo', {method: "POST",body: {name: "xxx"},server: false,})
</script>

nuxt.config.ts 

// https://nuxt.com/docs/api/configuration/nuxt-config
export default defineNuxtConfig({devtools: { enabled: true },modules: ['@nuxt/content',],vite: {server: {proxy: {'/api': {target: 'http://localhost:9090',changeOrigin: true,rewrite: (path) => path.replace(/^\/api/, '')}}}}
})

效果 

 

最后

Cookie需要遵守同源策略哦~
