var timeout_wrapper = function (req) {
return function () {
// do some logging, cleaning, etc. depending on req
req.abort();
};
};
但这种可能不够灵活，更高级的：
var timeout_wrapper = function (req) {
return function () {
// do some logging, cleaning, etc. depending on req
req.abort();
};
};
var request = http.get(options, function (res) {
res.on('data',function (data) {
file.write(data);
// reset timeout
clearTimeout(timeout);
timeout = setTimeout(fn, 10000);
}).on('end',function () {
// clear timeout
clearTimeout(timeout);
file.end();
console.log(file_name + ' downloaded ');
cb(null, file.path);
}).on('error', function (err) {
// clear timeout
clearTimeout(timeout);
console.log("Got error: " + err.message);
cb(err, null);
});
});
// generate timeout handler
var fn = timeout_wrapper(request);
// set initial timeout
var timeout = setTimeout(fn, 10000);
