我有一个非常简单的 nodejs 程序，用于演示与 Alchemer API 的通信。每当我运行以下代码时，代码都会引发错误ECONNREFUSED。但是，当我将相同的 url 复制到浏览器或 Postman 中时，它工作得很好。

注意 - 我注意到一件奇怪的事情，在错误的堆栈跟踪（见下文）中，它说地址是 127.0.0.1，即使我显然没有向我的本地主机发出请求......

Nodejs 代码段

require('dotenv').config();
const https = require('https');
const querystring = require('querystring');

console.log('Formulating query string...');

const params = {
    api_token: process.env.API_TOKEN,
    api_token_secret: process.env.API_TOKEN_SECRET
};

const reqArgs = querystring.stringify(params);

console.log('Query string: ', reqArgs);

const reqOptions  = {
    url: 'https://api.alchemer.com',
    path: '/v5/survey?' + reqArgs,
}

console.log('Test Url: ', reqOptions.url + reqOptions.path); // THIS WORKS IN THE 
BROWSER / POSTMAN
console.log('Getting data...');

https.request(reqOptions, resp => {
    let data = '';

    resp.on('data', chunk => {
        data += chunk;
    });

    resp.on('error', err => {
        console.error(JSON.stringify(err));
    });

    resp.on('end', () => {
        console.log('Request complete.');
        console.log(data);
    });
});

观察到的错误

events.js:292
      throw er; // Unhandled 'error' event
      ^

根据此处的https.requests文档，URL 似乎不是在请求选项中设置 URL 的正确属性名称。

考虑更改url您的reqOptionstohostname或host

const reqOptions  = {
    hostname: 'https://api.alchemer.com',
    path: '/v5/survey?' + reqArgs,
}
