parse authorization headers in python

To parse the Authorization header in Python, you can use the Authorization module from the http library. The Authorization module is a subclass of the HTTPHeader module, which allows us to parse the header fields from an HTTP request or response message.

Here's a sample code that shows how to parse the Authorization header using Authorization module in Python:

main.py
import http.client

# Parse the Authorization header
auth_header = "Bearer access_token"
auth_tokens = auth_header.split(" ")
if len(auth_tokens) != 2 or auth_tokens[0] != "Bearer":
    raise ValueError("Invalid Authorization header")

access_token = auth_tokens[1]

# Use the access token for authentication
conn = http.client.HTTPConnection("api.example.com")
headers = {"Authorization": f"Bearer {access_token}"}
conn.request("GET", "/resource", headers=headers)
response = conn.getresponse()
data = response.read()
print(data.decode("utf-8"))
547 chars
18 lines

In this example, we split the Authorization header string into two parts using the split method. We then check if the first part is "Bearer", and if there are exactly two parts. If these checks pass, we extract the access token from the second part.

We then use the access token to authenticate the request by adding it to the Authorization header of the outgoing request. Finally, we print the response from the API endpoint.
