Generic Solution However, there are some generic approaches to avoid getting detected while web scraping: The first and foremost attribute a website can determine your script/program by is through your monitor size. Any login information saved will be removed from your account permanently as soon as the task is deleted. Having said that, reCAPTCHA can easily detect the network traffic and identify your program as a Selenium driven bot.1) Manually enter Captcha in local extraction. Although Octoparse cannot deal with Captcha automatically, there are workarounds to this issue. They would ask you to solve a Captcha before you log in to your account or access the data. When a task is exported, the password saved in the task gets removed automatically by Octoparse. Captcha or reCaptcha is a common anti-scraping technique applied by many websites. In Octoparse, when you enter your password, it is only accessible on your own account.In many cases, the CAPTCHA is shown directly when we open the first page of the website, which breaks the whole scraping process. The website might recognize that it is a Cloud server IP instead of a residential IP that is accessing the pages. To solve this, you will need to go through the log in steps once again by adding in the proper actions in order to obtain and save the updated cookie. CAPTCHA is also a frequently used method for a website to anti-scrape. Very simple text-based captchas can be solved using OCR (theres a python library called pytesseract for this). In Octoparse, the saved cookie will no longer work when it gets expired. But if were redirected to a captcha, then it gets tricky. Some have a specific expiration time, others expire immediately as the browser is closed. Right-click on the action and select "Delete".Ī saved cookie is only effective before it gets expiredĬookies come in many different forms. Now as the web page is supposed to "remember" the login and skip the login steps, we'll remove the previously created actions for the login to avoid running into issues when the workflow is executed.Click "Load cookie from current web page".
