Node.js http.request fails with [Error: getaddrinf

问题:

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.

Request options usually are similar to:

{
  "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
  }
}

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

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

回答1:

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.
