How to Retrieve MIME Type Using a HEAD Request in Python 2?

Sending HEAD HTTP Request in Python 2 for MIME Type Retrieval

This question explores how to send a HEAD request in Python 2 to retrieve only the headers of a URL, allowing us to determine its MIME type without downloading the content.

Using urllib2 for HEAD Request:

The urllib2 library provides a simple solution for this need. It handles URL parsing, making it easier to set up the request, as seen in the following code snippet:

<code class="python">import urllib2

class HeadRequest(urllib2.Request):
    def get_method(self):
        return "HEAD"

response = urllib2.urlopen(HeadRequest("http://google.com/index.html"))</code>

This effectively sends a HEAD request to the specified URL and stores the response in the 'response' variable.

Retrieving Headers:

Headers are accessible through the 'response.info()' method, as shown below:

<code class="python">headers = response.info()</code>

Now you have access to the MIME type and other header information for the requested URL. Additionally, the 'response.geturl()' method reveals the final URL you were redirected to, if any.
