How to Fix HTTP Error 406: Not Acceptable in Python Web Scraping

If you're delving into the world of web scraping with Python, you might encounter various hurdles. One such hurdle is the dreaded HTTP Error 406: Not Acceptable. This error can be frustrating, especially when you're just trying to get your code to work. In this post, we'll break down what this error means and how you can solve it effectively.

Understanding HTTP Error 406

The HTTP Error 406: Not Acceptable status code indicates that the web server cannot produce a response that matches the list of acceptable values defined in the request's headers. Essentially, the server doesn't have the necessary resources or conditions required to fulfill the client’s request. This is a protocol-based issue rather than a coding mistake in your Python script.

The Solution: Adding a User Agent

To resolve this error, you need to modify the request headers to include a user agent. A user agent is a string that browsers and apps send to the server to identify themselves. By specifying a user agent, you can ensure that the server recognizes your request as coming from a legitimate web browser, which can help in preventing the 406 error.

Step-by-Step Implementation

Here's how you can modify your original code to include a user agent in the headers:

Update Your Imports: Make sure you import the Request class in addition to urlopen.

Create a Request Object: Use the Request class to create a new request object that will include the headers.

Add the User Agent: Set a user agent string that mimics a real web browser.

Revised Python Code

Here's the updated code incorporating the necessary changes:

What This Code Does:

Makes the Request: The code initializes a request with the specified URL.

Sets the User-Agent Header: The added line configures the request to carry the user agent string.

Parses the Page: The content is parsed using BeautifulSoup to extract necessary information from the HTML structure.

Output

Once run, the code will output a list containing dictionaries with the extracted links and their associated images and text. For example:
