带有HTTPS请求的Node.JS UnhandledException

我需要一些帮助，试图阻止节点抛出这个错误，或至less明白为什么我似乎无法赶上它：

events.js:72 throw er; // Unhandled 'error' event ^ Error: socket hang up at SecurePair.error (tls.js:999:23) at EncryptedStream.CryptoStream._done (tls.js:695:22) at CleartextStream.read [as _read] (tls.js:496:24) at CleartextStream.Readable.read (_stream_readable.js:320:10) at EncryptedStream.onCryptoStreamFinish (tls.js:301:47) at EncryptedStream.g (events.js:175:14) at EncryptedStream.EventEmitter.emit (events.js:117:20) at finishMaybe (_stream_writable.js:354:12) at endWritable (_stream_writable.js:361:3) at EncryptedStream.Writable.end (_stream_writable.js:339:5) at EncryptedStream.CryptoStream.end (tls.js:633:31) at Socket.onend (_stream_readable.js:483:10) 

这是导致错误的代码片段：

 var req = https.request(options, function(res) { res.setEncoding('utf8'); var buffer = ''; res.on('data', function(data) { buffer += data; }); res.on('end', function() { try { var json = JSON.parse(buffer); } catch (err) { return callback(err); } callback(null, json); }); }); req.on('error', function(err) { callback(err); }); req.end(data); api.prototype._get = function(action, callback, args) { args = _.compactObject(args); var path = '/api/' + action + '/?' + querystring.stringify(args); this._request('get', path, undefined, callback, args) } api.prototype._post = function(action, callback, args) { var path = '/api/' + action + '/'; args = _.compactObject(args); var data = querystring.stringify(args); this._request('post', path, data, callback, args); } 

为什么不req.on（“错误”捕捉这个错误？

您错过了响应的error handling程序。

 res.on('error', function errorHandler(err) { console.log(err); });
