Session Objects - Python requests Last Updated : 07 Jun, 2022 Comments Improve Suggest changes Like Article Like Report Session object allows one to persist certain parameters across requests. It also persists cookies across all requests made from the Session instance and will use urllib3’s connection pooling. So, if several requests are being made to the same host, the underlying TCP connection will be reused, which can result in a significant performance increase. A session object all the methods as of requests. Using Session Objects Let us illustrate the use of session objects by setting a cookie to a URL and then making a request again to check if the cookie is set. Python3 # import requests module import requests # create a session object s = requests.Session() # make a get request s.get('https://httpbin.org / cookies / set / sessioncookie / 123456789') # again make a get request r = s.get('https://httpbin.org / cookies') # check if cookie is still set print(r.text) Output One can check that cookie was still set when the request was made again. Sessions can also be used to provide default data to the request methods. This is done by providing data to the properties on a Session object: Python3 # import requests module import requests # create a session object s = requests.Session() # set username and password s.auth = ('user', 'pass') # update headers s.headers.update({'x-test': 'true'}) # both 'x-test' and 'x-test2' are sent s.get('https://httpbin.org / headers', headers ={'x-test2': 'true'}) # print object print(s) Output Comment More infoAdvertise with us Next Article Session Objects - Python requests N NaveenArora Follow Improve Article Tags : Python Python-requests Practice Tags : python Similar Reads response.json() - Python requests Python requests are generally used to fetch the content from a particular resource URL.
