Coupling setRequestInterception() with request.isNavigationRequest() and request.redirectChain() you can now abort navigation redirects in Puppeteer like this: await page.setRequestInterception(true); page.on(‘request’, request => { if (request.isNavigationRequest() && request.redirectChain().length) request.abort(); else request.continue(); }); await page.goto(‘https://example.com’);await page.setRequestInterception(true); page.on(‘request’, request => { if (request.isNavigationRequest() && request.redirectChain().length) request.abort(); else request.continue(); }); await page.goto(‘https://example.com’); References: https://github.com/GoogleChrome/puppeteer/issues/1132#issuecomment-393724933
With Express.js you can use req.query like this: var express = require(‘express’); var app = express(); app.get(‘/’, function(req, res){ res.send(‘id: ‘ + req.query.id); }); app.listen(8088);var express = require(‘express’); var app = express(); app.get(‘/’, function(req, res){ res.send(‘id: ‘ + req.query.id); }); app.listen(8088); It handles the $_GET[‘id’] GET query, i.e: http://127.0.0.1:8088/?id=123http://127.0.0.1:8088/?id=123
To split an array in chunks in NodeJs you can use splice(): var a = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15]; var b = a.splice(0,10); //a is now [11,12,13,14,15]; //b is now [1,2,3,4,5,6,7,8,9,10];var a = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15]; var b = a.splice(0,10); //a is now [11,12,13,14,15]; //b is now [1,2,3,4,5,6,7,8,9,10]; You can also loop the array and do something with the […]
