javascript - 获取请求失败，错误为 : connect ECONNREFUSED

Question

我正在尝试向服务器发送获取请求。但我收到以下错误，知道如何避免该错误吗？

错误:

events.js:183 throw er; // Unhandled 'error' event ^

Error: connect ECONNREFUSED ****** at Object._errnoException (util.js:992:11) at _exceptionWithHostPort (util.js:1014:20) at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1186:14)

我的要求:

var https = require("https");

// Update these options with the details of the web service you would like to call
var options = {
  method: 'GET',
  uri: 'https:*****',
  resolveWithFullResponse: true,
  json: true
};

var req = https.request(options, res => {
  res.setEncoding('utf8');
  var returnData = "";

  res.on('data', chunk => {
    returnData = returnData + chunk;
  });
  res.on('end', () => {
    console.log('returndata: ' + JSON.stringify(returnData))
    var pop = JSON.parse(returnData).population;
    callback(pop);
  });
});
req.end();

这是一个示例，您不能在选项对象上设置 uri，您可以使用 uri 字符串/URI 对象，或者使用此请求类型的选项对象(请参阅 Node.js http.request docs)

const https = require('https');

const options = {
    hostname: 'jsonplaceholder.typicode.com',
    path: '/todos/1',
};

const req = https.request(options, (res) => {
    let returnData = "";

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

    res.on('end', () => {
        console.log('returndata: ', returnData);
    });
});

req.on('error', (e) => {
    console.error(e);
});

req.end();
