http response status

ist there any way to handle a response status explicitly? (puppeteer/cheerio) there seems to be a response parameter in the requesthandler but I don't know how to use that. so e.g looking to handle a 400 response code...

const crawler = new CheerioCrawler({
    requestHandler: ({ response }) => {
        console.log(response.statusCode);
    }
})

Thanks @thek1tten

    async requestHandler({
      request, page, log, response,
    }) {
      console.log(response.statusCode);

Cannot read properties of undefined (reading 'statusCode') I'm using a PuppeteerCrawler, does this make a difference? Obviously ist does. Seems like response object doesn't have a statusCode in PuppeteerCrawler, works in Cheerio

PuppeteerCrawler returns a Puppeteer HTTPResponse object. https://pptr.dev/next/api/puppeteer.httpresponse/ Grab the status from it with the .status() function.

import { PuppeteerCrawler } from 'crawlee';

const crawler = new PuppeteerCrawler({
    requestHandler: ({ response }) => {
        console.log(response.status());
    }
})

import { PuppeteerCrawler } from 'crawlee';

const crawler = new PuppeteerCrawler({
    requestHandler: ({ response }) => {
        console.log(response.status());
    }
})

HTTPResponse class | Puppeteer

The HTTPResponse class represents responses which are received by the Page class.

You can also adjust the blocked status code of sessionPool https://crawlee.dev/api/core/interface/SessionPoolOptions#blockedStatusCodes

@Lukas Krivka if I block it I can't handle it in my code anymore, right?

dependent-tan•3y ago

@bs Correct. For example, if you add the 200 status code to the blocked list, the request will immediately retry and the requestHandler for that request will not be executed.

Thanks @thek1tten that's what i thought. I'd rather handle the different status codes by myself 🙂

So you can make the list empty 😄
