为什么不调用https.request回调？

Question

我有一些node.js代码,我正在尝试从raw.github.com获取package.info.我正在做一个HTTPS请求,但由于某种原因,它似乎永远不会调用回调,因为'here'永远不会输出.

有谁看到出了什么问题？

console.log(options)

req = https.request(options, function(res) {
  console.log('here')
  res.setEncoding('utf8')
  // ... more code here
 })

 console.log(req)

 // .. return -> listening and waiting

产量

{ host: 'raw.github.com',
  port: 443,
  path: '/jasny/bootstrap/2.2.2-j3-wip/package.json',
  method: 'GET' }
{ domain: null,
  _events:
   { response: { [Function: g] listener: [Function] },
     socket: { [Function: g] listener: [Function] } },
  _maxListeners: 10,
  output: [],
  outputEncodings: [],
  writable: true,
  _last: false,
  chunkedEncoding: false,
  shouldKeepAlive: true,
  useChunkedEncodingByDefault: false,
  sendDate: false,
  _hasBody: true,
  _trailer: '',
  finished: false,
  agent:
   { domain: null,
     _events: { free: [Function] },
     _maxListeners: 10,
     options: {},
     requests: {},
     sockets: { 'raw.github.com:443': [Object] },
     maxSockets: 5,
     createConnection: [Function: createConnection] },
  socketPath: undefined,
  method: 'GET',
  path: '/jasny/bootstrap/2.2.2-j3-wip/package.json',
  _headers: { host: 'raw.github.com' },
  _headerNames: { host: 'Host' }
}

有关完整代码,请参阅lib/packageinfo.js.该函数在index.js中调用

您需要调用end()请求来执行它,如下所示:

req = https.request(options, function(res) {
  console.log('here')
  res.setEncoding('utf8')
  // ... more code here
});
req.end();   // <= Here
