使用nodejs从ibm云函数调用http GET请求

const https = require('https');

function main(params) {
  return new Promise((resolve, reject) => {
    const options = {
      hostname: 'api.example.com',
      path: '/endpoint',
      method: 'GET'
    };

    const req = https.get(options, (res) => {
      let data = '';

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

      res.on('end', () => {
        resolve(data);
      });
    });

    req.on('error', (err) => {
      reject(err);
    });

    req.end();
  });
}
