Node.js的学习入门（三、发送请求）

let http = require('http');

let util = require('util');

http.get('http://www.hao123.com/sugdata_s4.json?r=-838709',  (res) => {

  const { statusCode } = res;
  const contentType = res.headers['content-type'];

  console.log(statusCode);
  console.log(contentType);
  let error;
  if (statusCode !== 200) {
    error = new Error('请求失败。\n' +
      `状态码: ${statusCode}`);
  } else if (!/^application\/json/.test(contentType)) {
    error = new Error('无效的 content-type.\n' +
      `期望 application/json 但获取的是 ${contentType}`);
  }

  let data = '';
  res.on("data", function (chunk) {
    data += chunk;
  });

  res.on("end", function () {
    let result = JSON.parse(data);
    console.log("result:"+ util.inspect(result));
  });



});
