Python Requests Options

If you are working with APIs or web scraping, you may have come across the need to send HTTP requests to a server. Python Requests is a popular library for sending HTTP requests in Python.

The Options Method

The HTTP Options method is used to retrieve the communication options available for a given URL. This method returns a list of methods that are available for the URL.

To send an Options request using Python Requests, you can use the options() method of the requests library. Here is an example:


import requests
response = requests.options('https://jsonplaceholder.typicode.com/posts')
print(response.status_code)
print(response.headers['allow'])
  • The options() method takes the URL as the first argument.
  • We then print the status code and the Allow header from the response object.

The above code will send an Options request to the given URL and return the list of HTTP methods that are allowed for that URL.

Passing Headers

You can also pass headers while making a request. For example:


import requests
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'
}
response = requests.options('https://jsonplaceholder.typicode.com/posts', headers=headers)
print(response.status_code)
print(response.headers['allow'])
  • We define a dictionary of headers where we specify the User-Agent header.
  • We then pass this headers dictionary as the second argument to the options() method.
  • We again print the status code and the Allow header from the response object.

The above code will send an Options request to the given URL with the specified User-Agent header and return the list of HTTP methods that are allowed for that URL.

Using a Session

If you are making multiple requests to the same server, it is recommended that you use a session. A session will persist cookies across requests and improve performance.


import requests
session = requests.Session()
response = session.options('https://jsonplaceholder.typicode.com/posts')
print(response.status_code)
print(response.headers['allow'])
  • We create a session object using the requests.Session() method.
  • We then use this session object to send an Options request to the given URL.
  • We again print the status code and the Allow header from the response object.

The above code will send an Options request to the given URL using a session object and return the list of HTTP methods that are allowed for that URL.

Conclusion

The Python Requests library provides a simple and easy-to-use interface for sending HTTP requests. The Options method can be used to retrieve the communication options available for a given URL. You can also pass headers and use a session for improved performance.
