访问/delcookie路由时浏览器挂起? [英] Browser hangs when accessing /delcookie route?

问题描述

我能够设置和打印cookie对象，但是当我访问 delcookie 路由时，浏览器将挂起并且不会删除cookie.

I am able to set and print the cookie object but when I access the delcookie route, my browser hangs and does not delete the cookie.

我的语法对delcookie路由是否正确?

Is my syntax correct for the delcookie route?

var express = require ("express");
var app = express();

app.use( express.cookieParser() );

app.get('/setcookie', function(req, res){
  res.cookie('cookiename', 'cookievalue', { maxAge: 900000, httpOnly: true });
  res.send ('200', "<div style='font-weight:bold; color:blue'>setting cookie</div>");
  console.log (req.cookies);
});

app.get('/printcookie', function(req, res){
  res.send ('200', "<div style='font-weight:bold;'>printing cookie</div>");
  console.log (req.cookies);
});

app.get('/delcookie', function(req, res){
  res.clearCookie('cookiename', { path: '/setcookie' });
});

app.listen(1337);

推荐答案

您实际上不是在发送响应. sendCookie 方法告诉Express添加一个标头，该标头将在发送响应后删除cookie.

You aren't actually sending a response. The sendCookie method tells Express to add a header that will delete the cookie when the response is sent.

添加确实会发送响应的内容:

Add something that does send a response:

app.get('/delcookie', function(req, res){
  res.clearCookie('cookiename', { path: '/setcookie' });
  res.send('ok');
});
