写了一段用代理请求的代码，可是总会出现socket hang up的问题，我觉得是没有关闭request，但是加了req.end()之后，又会出现下面的错误。 req.abort(); ^ TypeError: Object false has no method ‘abort’ at null._onTimeout (/home/ilolita/node_model/spider/crawler/test/timeOutTest.js:6:9) at Timer.listOnTimeout [as ontimeout] (timers.js:110:15)

请问大神们这个问题怎么解决？？

var http = require(‘http’);

var request_timer = null, req = null; // 请求5秒超时 request_timer = setTimeout(function() { req.abort(); console.log(‘Request Timeout.’); }, 5000);

var options = { host: '180.118.105.153’, port: '18186’, path: ‘http://www.cnodejs.org/’ };

req = http.get(options, function(res) { clearTimeout(request_timer);

// 等待响应60秒超时
var response_timer = setTimeout(function() {
    res.destroy();
    console.log('Response Timeout.');
}, 60000);

console.log("Got response: " + res.statusCode);
var chunks = [], length = 0;
res.on('data', function(chunk) {
    length += chunk.length;
    chunks.push(chunk);
});
res.on('end', function() {
    clearTimeout(response_timer);
    console.log(res.headers);
});

}).on('error’,function(err){ console.log('Error: '+ err ); });
