Python Requests Multiple Headers

Have you ever encountered a situation where you needed to pass multiple headers in a Python Requests call? This is a common requirement when working with APIs that require authentication, authorization, or additional custom headers.

Method 1: Passing Headers as a Dictionary

The simplest and most common way to pass multiple headers is by adding them as key-value pairs to a dictionary and then passing this dictionary as the headers argument in the Requests call.


import requests

headers = {
    'Authorization': 'Bearer xxxxxxxx',
    'Content-Type': 'application/json'
}

response = requests.post('https://api.example.com', headers=headers)

In the example above, we are passing two headers: Authorization with a Bearer token and Content-Type with a value of application/json.

Method 2: Using the Headers Object

You can also create a headers object and use its methods to add or update headers. This approach is useful when you need to modify headers dynamically.


import requests

headers = requests.Headers()
headers['Authorization'] = 'Bearer xxxxxxxx'
headers['Content-Type'] = 'application/json'

response = requests.post('https://api.example.com', headers=headers)

In the example above, we are creating a Headers object and adding two headers using its __setitem__() method.

Method 3: Combining Headers

Sometimes, you may need to combine multiple headers into a single header. For example, you may need to pass a custom header that combines a user's access token and user ID.


import requests

access_token = 'xxxxxxxx'
user_id = '12345'

combined_header = f'Bearer {access_token};user-id={user_id}'

headers = {
    'Authorization': combined_header,
    'Content-Type': 'application/json'
}

response = requests.post('https://api.example.com', headers=headers)

In the example above, we are combining the access_token and user_id into a single header string and passing it as the Authorization header.

These are some of the ways you can pass multiple headers in Python Requests. Choose the method that works best for your use case and make sure to test your code thoroughly.
