Node.js http.request失败，并显示[错误:getaddrinfo EADDRINFO]

问题描述

我有充当代理的node.js服务器.通过执行http.request，它接收请求并将它们转发到另一个域上的Web服务.

I have node.js server which acts like a proxy. It receives requests and forwards them to web service on another domain, by executing http.request.

请求选项通常类似于:

{
  "host": "some.domain",
  "port": 443,
  "path": "/paht/item/id",
  "method": "POST",
  "headers": {
    "Host": "some.domain",
    "Content-Type": "application/json; charset=utf-8",
    "Content-Length": 100
  }
}

最近，我注意到有些请求因[Error: getaddrinfo EADDRINFO]失败，但并非全部.

Lately, I've noticed that some requests fail with [Error: getaddrinfo EADDRINFO], but not all of them.

有人知道EADDRINFO是什么意思，以及所谓的原因可能是什么?

Does anyone know what EADDRINFO means, and what the alleged cause can be?

推荐答案

EAADRINFO是一种错误类型，在找不到IP地址的情况下查找主机名的IP地址时可能会发生.因此，这很可能意味着请求的"some.domain"值无法解析为IP地址.

EAADRINFO is an error type that can occur when looking up a host name's IP address for the case where an IP address cannot be found. So here it likely means that the "some.domain" value of the request can't be resolved to an IP address.
