php - 如何通过 lambda 脚本将 JSON 数据发布到另一台服务器

Question

我正在尝试从 AWS lambda 函数将一些 JSON 数据(从 DaynamoDB 获取)发送到另一台服务器，但同时在脚本中给出 URL:

'use strict';

const https = require('https');

exports.handler = (event, context, callback) => {

      var options = {
      hostname: 'https://www.corecomputersystem.com',
      path: '/getSyncData.php',
      port : 432,
      method: 'POST',
      headers: {
          'Content-Type': 'application/json',
      }
    };
     event.Records.forEach((record) => {

        console.log(record.eventID);
        console.log(record.eventName);
        console.log('DynamoDB Record: %j', record.dynamodb);
        var res = record.dynamodb;

        const req = https.request(options, (res) => {
        let body = "";
        console.log('Status:', res.statusCode);
        console.log('Headers:', JSON.stringify(res.headers));
        res.setEncoding('utf8');
        res.on('data', (chunk) => body += chunk);
        res.on('end', () => {
            console.log('Successfully processed HTTPS response');
            // If we know it's JSON, parse it
            if (res.headers['content-type'] === 'application/json') {
                body = JSON.parse(body);
            }
            callback(null, body);
        });
    });
    req.on('error', callback);
    req.write(JSON.stringify(event.data) + "");
    req.end();
    //context.succeed();
    });

};

它抛出以下错误，

{
  "errorMessage": "getaddrinfo ENOTFOUND https://www.corecomputersystem.com https://www.corecomputersystem.com:432",
  "errorType": "Error",
  "stackTrace": [
    "errnoException (dns.js:26:10)",
    "GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:77:26)"
  ]
}

如果我取消注释 context.succeed()，则不会出现错误，我需要帮助来识别错误。

就深度而言，@at0mzk 表示，主机名永远不会采用任何端口号，因此任何像 [http、https、smb、nfs]://这样的前缀都会在请求主机名的任何地方引发错误。

( http://localhost === 本地主机:80)
