为什么会出现此错误：错误：连接ECONNREFUSED？

编程问答 2022-06-12

问题描述

我正在尝试连接到API Mailchimp，但是启动app.js时出现此错误。

import mailchimp from "@mailchimp/mailchimp_marketing";

mailchimp.setConfig({
  apiKey: "apiKey",server: "server",});

async function run() {
  const response = await mailchimp.ping.get();
  console.log(response);
}

run();

这是完整的错误： 

(node:27226) UnhandledPromiseRejectionWarning: Error: connect ECONNREFUSED 0.0.0.0:443
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1144:16)
(Use `node --trace-warnings ...` to show where the warning was created)
(node:27226) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block,or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection,use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)
(node:27226) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future,promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
