koa中的cookie使用

• 基础用法

const Koa = require("koa");
const path = require("path");
const Router = require("koa-router");

const render = require("koa-art-template");

const app = new Koa();
const router = new Router();

render(app, {
  root: path.join(__dirname, "views"),
  extname: ".html",
  debug: true
});

router.get("/", async (ctx, next) => {
  ctx.cookies.set("userinfo", "JonSnow", {
    maxAge: 10 * 1000
  });
  await ctx.render("index");
});

router.get("/news", async (ctx, next) => {
  const userinfo = ctx.cookies.get("userinfo");
  await ctx.render("news", {
    name: "JonSnow",
    userinfo
  });
});

app.use(router.routes()).use(router.allowedMethods());

app.listen(8080);

有一个问题，无法存储中文，可通过Buffer将汉字转换为base64进行存储
