Bypass Robots Txt
how to bypass robots.txt while crawling – Stack Overflow
Can anyone please tell me if there is any way to ignore or bypass while crawling. Is there any way to modify script in such way that it ignores and go on with crawling?
Or is there any other way to achieve the same?

If you are writing a crawler then you have complete control of it. You can make it behave nicely or you can make it behave badly.
If you don’t want your crawler to respect then just write it so it doesn’t. You might be using a library that respects automatically, if so then you will have to disable that (which will usually be an option you pass to the library when you call it).
There is no way to use client side JavaScript to cause a crawler reading the page embedding the JS to stop respecting

if you are writing Crawler in mechanize (Python) and have an interface with
then use the following command:
import mechanize
br = owser()
t_handle_robots(False)

How to ignore robots.txt for Scrapy spiders – Simplified Guide
Website owners tell web spiders such as Googlebot what can and can’t be crawled on their websites file. The file resides on the root directory of a website and contains rules such as the following;
User-agent: *
Disallow: /secret
Disallow:
A good web spider will first read the file and adhere to the rule, though it’s actually not compulsory.
If you run a scrapy crawl command for a project, it will first look for the file and abide by all the rules.
$ scrapy crawl myspider
2018-06-19 12:05:10 [] INFO: Scrapy 1. 5. 0 started (bot: scrapyproject)
—snipped—
2018-06-19 12:05:10 [scrapy. middleware] INFO: Enabled downloader middlewares:
[‘botsTxtMiddleware’,
2018-06-19 12:05:11 [] DEBUG: Crawled (200)
You can ignore for your Scrapy spider by using the ROBOTSTXT_OBEY option and set the value to False.
Steps to ignore for Scrapy spiders:
Crawl a website normally using scrapy crawl command for your project to use the default to adhere to rules. $ crapy crawl spidername
Use set option to set ROBOTSTXT_OBEY option to False when crawling to ignore rules. $ crapy crawl –set=ROBOTSTXT_OBEY=’False’ spidername
Open Scrapy’s configuration file in your project folder using your favorite editor. $ vi scrapyproject/
Look for the ROBOTSTXT_OBEY option. # Obey rules
ROBOTSTXT_OBEY = True
Set the value to FalseROBOTSTXT_OBEY = False
Scrapy should no longer check for and your spider will crawl for everything regardless of what’s defined in the file.
