为什么不调用https.request回调？(Why isn't the https.request callback called?)

为什么不调用https.request回调？(Why isn't the https.request callback called?)

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，它看起来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

I have some node.js code where I'm trying to get package.info from raw.github.com. I'm doing a HTTPS request, but for some reason it looks like the callback is never called, because 'here' is never outputted.

Does anyone see what's going wrong?

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

Output

{ 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' } }

For the full code see lib/packageinfo.js. The function is called in index.js

最满意答案

您需要在请求上调用end()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

You need to call end() on the request to execute it, like this:

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