Multiple Headers in Python Requests

Python Requests is a popular library used for making HTTP requests in Python. When making requests, it's often necessary to include headers to provide additional information about the request. Headers can be used to pass authentication credentials, specify the content type of the request, and more.

Adding Multiple Headers in Requests

To add multiple headers in Python Requests, you can use a dictionary to specify the headers. Here's an example:


import requests

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

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

In this example, we've defined a dictionary called `headers` that contains two key-value pairs. The first key is `Authorization` and its value is `Bearer my_access_token`. The second key is `Content-Type` and its value is `application/json`. We then pass this dictionary as the `headers` argument to the `requests.get()` method.

Adding Headers with Different Values for Different Requests

Often times, you may want to use different headers for different requests. In this case, you can simply define a dictionary of headers for each request. Here's an example:


import requests

# Define headers for first request
headers1 = {
    'Authorization': 'Bearer my_access_token_1',
    'Content-Type': 'application/json'
}

# Make first request with headers1
response1 = requests.get('https://api.example.com', headers=headers1)

# Define headers for second request
headers2 = {
    'Authorization': 'Bearer my_access_token_2',
    'Content-Type': 'application/xml'
}

# Make second request with headers2
response2 = requests.post('https://api.example.com', headers=headers2)

In this example, we've defined two dictionaries of headers - `headers1` and `headers2`. We then use each of these dictionaries for the corresponding requests. The first request uses `headers1` and the second request uses `headers2`.

Conclusion

In Python Requests, you can add multiple headers to HTTP requests using a dictionary. If you need to use different headers for different requests, simply define a dictionary of headers for each request. This makes it easy to customize your requests with the necessary headers.
