Node.js无法在Windows上解析'localhost' [英] nodejs cannot resolve 'localhost' on windows

问题描述

以下代码在Windows下的node.js中产生异常:

The following code produces an exception in node.js under windows:

var Socket = require("net").Socket;

socket = new Socket();
socket.connect(80, "localhost");

这是消息:

    events.js:2083: Uncaught Error: getHostByName ENOTFOUND

当我删除localhost时，它可以正常工作.是什么原因造成的? 我尝试关闭防火墙，但没有效果.

When I remove localhost, it works fine. What could be causing this? I tried turning the firewall off, but to no effect.

推荐答案

node.js使用c-ares解析器，而完全忽略系统解析器.因此，有关C:\ WINDOWS \ system32 \ drivers \ etc \ hosts的建议可能无关紧要.

node.js uses c-ares resolver and ignores system resolver completely. So the advices regarding C:\WINDOWS\system32\drivers\etc\hosts are probably irrelevant.

c-ares库读取某些系统配置文件-例如在Windows和Cygwin上，其读取为/etc/resolv.conf.因此，您应该检查它是否读取/etc/hosts或C:\ WINDOWS \ system32 \ drivers \ etc \ hosts.如果没有并且没有对本地主机的内置支持-那么您将不得不使用127.0.0.1

c-ares library reads certain system config files - e.g. on Windows and Cygwin it reads /etc/resolv.conf. So you should check if it reads /etc/hosts or C:\WINDOWS\system32\drivers\etc\hosts. If it doesn't and doesn't have builtin support for localhost - then you will have to use 127.0.0.1
