Node.js http请求内存和cpu hog
|
我有一个连续请求页面的node.js脚本，有点像cron作业。
但是，几分钟后，Node开始使用大量CPU（最多70％）和内存（最多200mb）。
我的脚本有什么问题？
function cron(path)
{
var http = require(\'http\');
var site = http.createClient(443, \'www.website.com\', true);
var request = site.request(\'GET\', path, {\'host\': \'www.website.com\'});
request.end();
request.on(\'response\', function (response) {
setTimeout(function(){cron(path)},15000);
});
}
cron(\'/path/to/page\');

request.on(\'response\', function (response) { setTimeout(function(){cron(path)},15000); });创建了function() {}您在函数内部而不是模块范围外部调用。您只需要获得一次ѭ7，就可以放在模块作用域中文件的顶部。var http = require(\'http\'); var site = http.createClient(443, \'www.website.com\', true); function cron(path) { var request = site.request(\'GET\', path, {\'host\': \'www.website.com\'}); request.end(); var once = true; request.on(\'response\', doIt); function doIt(response) { if (!once) { once = null; doIt = function() {}; setTimeout(function(){cron(path)},15000); } }); site = null; request = null; } cron(\'/path/to/page\');臀博
var https = require(\'https\'); function poll(path) { https.get({ host: \'www.website.com\', port: 443, path: path }, function(res) { console.log(\"Got response: \" + res.statusCode); }).on(\'error\', function(e) { console.log(\"Got error: \" + e.message); }); } function cron(path) { return setInterval(function(){ poll(path); },15000); } var intervalId = cron(\'/path/to/page\'); // keep in case you need to use clearInterval
