Some websites need you to login with user account and password before scraping data. Octoparse supports scraping data from websites which require authentication. While using Octoparse to scrape data from such websites please follow the steps below.
Step 1 Set Basic Information
First of, Enter the task name. Save your task to a category. Then click “next” to the second step.
Step 2 Design Workflow
Open the login page URL in the build-in browser.
Click the first textbox. Choose "Enter text value".
Type in your account in the input box under Customize Current Action. Click ”save".
Click the second textbox and select "Enter text value" again.
Type in your password and click "save".
Then click on sign-in button. Select "click an item".
Sometimes, the elements on the web page is not all loaded at the same time. Some elements may load later. If the item that you choose to click is not loaded and the page stopped loading, you need to set Ajax timeout.
Choose "load page with AJAX", then set Ajax time out. Click "save".
Then you can start to scrape data. Once done configuring extraction rule, click next.
You can choose not to load images to speed up the extraction. But sometimes may cause problems on certain websites. Then click “Next”.
