[NODE之四]http模块练习2

昨天弄了个服务器和调用。今天写了个iphone的测试应用，专门对req.headers进行测试。发现这个headers里面还真有好多信息，怪不得http叫名文协议。服务器端代码和昨天一样，就是加了console.log(req.headers);api的请求把headers的配置项都去掉了，先暂时不用这种“野”方法。

API的post的headers

{ host: 'localhost:3001',
      connection: 'close',
      'transfer-encoding': 'chunked' }

API的get的headers

{ host: 'localhost:3001', connection: 'close' }

IOS模拟器post的headers

{ host: '127.0.0.1:3001',
      'content-type': 'application/x-www-form-urlencoded',
      connection: 'keep-alive',
      accept: '*/*',
      'user-agent': 'CallHttpForNode/1.0 (iPhone; iOS 10.2; Scale/2.00)',
      'accept-language': 'en;q=1',
      'content-length': '43',
      'accept-encoding': 'gzip, deflate' }

iOS模拟器get的headers

{ host: '127.0.0.1:3001',
      accept: '*/*',
      'accept-language': 'en;q=1',
      connection: 'keep-alive',
      'accept-encoding': 'gzip, deflate',
      'user-agent': 'CallHttpForNode/1.0 (iPhone; iOS 10.2; Scale/2.00)' }

chrome浏览器的headers

{ host: 'localhost:3001',
      connection: 'keep-alive',
      'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36',
      accept: '*/*',
      referer: 'http://localhost:3001/?name=%27%E7%99%BE%E5%BA%A6%27&url=%27www.baidu.com%27',
      'accept-encoding': 'gzip, deflate, sdch',
      'accept-language': 'zh-CN,zh;q=0.8,en;q=0.6',
      cookie: 'Webstorm-97ccd078=b588c8c8-9e96-432e-a4f7-30f754875a16' }

最后，ios端的代码
