本地主机不能在Chrome中工作，127.0.0.1确实有效

问题描述

我试图运行本地节点服务器，但无论出于何种原因 localhost：3000 都不起作用。错误页面显示该网页不可用ERR_CONNECTION_CLOSED 但是， 127.0.0.1:3000 确实有效。我试图更改我的主机文件，但无济于事。有谁知道是什么原因导致了这个问题？

Chrome版本为46.0.2490.80米

解决方案

1. 编辑我的hosts文件，使<$ c $


2. 清理我的Chrome缓存，特别是Cookie和缓存文件


3. 清除 chrome：// net-internals /＃dns
中的主机缓存

4. 重新启动Chrome浏览器

另外，这也适用：

1. 导航到chrome：// net-internals /＃hsts


2. 在删除域下，输入 localhost 并删除

我不知道，我的项目有一个HSTS中间件，它设置了一个HSTS cookie




I'm trying to run a local node server, but for whatever reason localhost:3000 does not work. The error page states This webpage is not available ERR_CONNECTION_CLOSED However, 127.0.0.1:3000 does work. I have tried making changes to my hosts file, but to no avail. Does anyone have any idea what's causing the problem?

Chrome version is 46.0.2490.80 m

解决方案

Here are the steps I took to make this work correctly:

1. Edited my hosts file so 127.0.0.1 localhost. was present, and saved the file
2. Cleared my Chrome cache, specifically cookies and cached files
3. Cleared host cache in chrome://net-internals/#dns
4. Restarted chrome

Alternatively, this also works:

1. Navigate to chrome://net-internals/#hsts
2. Under "Delete domain", type localhost and delete

Unbeknownst to me, my project had an HSTS middleware that set an HSTS cookie
