为什么会出现这个错误：Error: connect ECONNREFUSED?

Question

我正在尝试连接到 API Mailchimp，但在启动

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)

Answer 1

ECONNREFUSED

表示您的操作系统无法建立 TCP 连接。

0.0.0.0:443

上没有监听任何服务，这是您自己的计算机。您确定

0.0.0.0

是您需要连接的主机吗？

您需要在计算机上启动所需的服务，或者需要使用正确的 IP 地址（无论是什么）。
