A Http request is meant to either retrieve data from a specified URI or to push data to a server. It works as a request-response protocol between a client and a server. Let’s demonstrate how to make a GET request to an method is used to retrieve information from the given server using a given URI. The GET method sends the encoded user information appended to the page request. The page and the encoded information are separated by the ‘? ’ example: to make GET request through Python RequestsPython’s requests module provides in-built method called get() for making a GET request to a specified –(url, params={key: value}, args)
Example –Let’s try making a request to github’s APIs for example this file as and through terminal run, python Output –For more, visit GET method – Python requestsHttp Request Methods –MethodDescriptionGETGET method is used to retrieve information from the given server using a given POST request method requests that a web server accepts the data enclosed in the body of the request message, most likely for storing itPUTThe PUT method requests that the enclosed entity be stored under the supplied URI. If the URI refers to an already existing resource, it is modified and if the URI does not point to an existing resource, then the server can create the resource with that LETEThe DELETE method deletes the specified resourceHEADThe HEAD method asks for a response identical to that of a GET request, but without the response TCHIt is used for modify capabilities. The PATCH request only needs to contain the changes to the resource, not the complete resourceResponse objectWhen one makes a request to a URI, it returns a response. This Response object in terms of python is returned by (), method being – get, post, put, etc. Response is a powerful object with lots of functions and attributes that assist in normalizing data or creating ideal portions of code. For example, atus_code returns the status code from the headers itself, and one can check if the request was processed successfully or sponse object can be used to imply lots of features, methods, and functionalities. Example:import requestsprint()print(atus_code)Save this file as, and run using below commandPython Status code 200 indicates that request was made sponse MethodsMethodDescriptionresponse. headersresponse. headers returns a dictionary of response sponse. encodingresponse. encoding returns the encoding used to decode sponse. elapsedresponse. elapsed returns a timedelta object with the time elapsed from sending the request to the arrival of the ()() closes the connection to the ntent returns the content of the response, in okies returns a CookieJar object with the cookies sent back from the sponse. historyresponse. history returns a list of response objects holding the history of request (url)_permanent_redirect returns True if the response is the permanent redirected url, otherwise _redirect returns True if the response was redirected, otherwise er_content()er_content() iterates over the ()() returns a JSON object of the result (if the result was written in JSON format, if not it raises an error) returns the URL of the returns the content of the response, in atus_code returns a number that indicates the status (200 is OK, 404 is Not Found)quest returns the request object that requested this returns a text corresponding to the status sponse. raise_for_status()response. raise_for_status() returns an HTTPError object if an error has occurred during the returns True if status_code is less than 200, otherwise returns the header thentication using Python RequestsAuthentication refers to giving a user permissions to access a particular resource. Since, everyone can’t be allowed to access data from every URL, one would require authentication primarily. To achieve this authentication, typically one provides authentication data through Authorization header or a custom header defined by server. Example –import requestsfrom import HTTPBasicAuth auth = HTTPBasicAuth(‘user’, ‘pass’))print(response)Replace “user” and “pass” with your username and password. It will authenticate the request and return a response 200 or else it will return error more visit – Authentication using Python requestsSSL Certificate VerificationRequests verifies SSL certificates for HTTPS requests, just like a web browser. SSL Certificates are small data files that digitally bind a cryptographic key to an organization’s details. Often, an website with a SSL certificate is termed as secure website. By default, SSL verification is enabled, and Requests will throw a SSLError if it’s unable to verify the certificate. Disable SSL certificate verificationLet us try to access a website with an invalid SSL certificate, using Python requestsOutput:-This website doesn’t have SSL setup so it raises this can also pass the link to the certificate for validation via python requests requestsresponse = (”, verify =’/path/to/certfile’)print(response)This would work in case the path provided is correct for SSL certificate for more visit- SSL Certificate Verification – Python requestsSession ObjectsSession 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 Session ObjectsLet us illustrate use of session objects by setting a cookie to a url and then making a request again to check if cookie is set.

When you are working on the web, for business or personal purposes, you are likely to look for some information. Or you may want to use a website for viewing videos, uploading data or checking social media. To get access to all these resources on the Internet, you have to send a request through your browser to the Internet sever.
HTTP (Hypertext Transfer Protocol) is the set of rules that enable communication between a client and a server over the Internet. While programming in Python, you can make these requests using a module called requests. To gain expertise in python, check out our data science courses.
In this article, we will learn the basics of the Python requests module.
Python Requests moduleGET RequestPOST RequestWrapping Up
Python Requests module
The requests module in Python allows you to exchange requests on the web. It is a very useful library that has many essential methods and features to send HTTP requests. As mentioned earlier, HTTP works as a request-response system between a server and a client. Your web browser may be the client, and the system that hosts the site you want to access is the server. Check out all important python libraries.
When you are looking to send a request to a server, there are two methods that you will come across:
GET – This method is used for requesting data from a server.
POST – This method is used for submitting some data to the server for processing it.
The Python requests module has a simple API that you can use for handling all these requests. It offers you many interesting features, such as passing parameters within URLs, adding headers, sending custom headers and much more.

To begin working with the requests module, the first step is to install the module in Python. To do so, type in the following code in Python:
$ pip install requests
In case you want to use Pipenv, a Python packaging tool for installing the requests module, type in the following code:
$ pipenv install requests
After installing the module, you can use it within your programs by importing it. Use the following code:
import requests
Now, let us understand the most important methods of the python requests module – GET and POST.
GET Request
This method is used for sending a GET request to a URL. This indicates that you are looking to obtain data from a resource on the web. The basic syntax is:
(url, params={key: value}, args)
Here, url is the URL of the website where you want to send the request. The params is a dictionary or a list of tuples used to send a query string. The args can be any one or more of the various named arguments (optional) offered by the GET method. And, these are:
allow_redirects – This is a Boolean value used to enable or disable redirection. Default value: True
auth – This is a tuple for enabling an HTTP authentication. Default value: None
cert – This can be a tuple or a string for mentioning a cert file or key. Default value: None
timeout – It is can be a tuple or a number that indicates the number of seconds to wait for the client to establish a connection or before sending a response. Default value: None
verify – This is a string or a Boolean value that indicates the server’s TLS certificate verification. The default value is True.
cookies – This is a dictionary of cookies that you want to send to the specified URL. Default value: None
headers – This is a dictionary containing HTTP headers that you wish to send to a URL. Default value: None
stream – It is a Boolean value True or False that indicates whether the response should be streamed (True) or immediately downloaded (False). Default value: False
proxies – This is a dictionary of the protocol for the proxy URL. Default value: None

After successfully sending the GET request, the method will return a sponse object. This object stores the response that is obtained from the server. You can store the result of the get() method in a variable. Then, you can examine the details of this response. The important properties that help you in this regard are as follows:
ntent – This gives you the content of the data of the response.
atus_code – This gives you the status of your request. For example, 200 OK means your request was successful, but 404 NOT FOUND means your request could not locate the resource for you.
okies – This is used for obtaining a CookieJar object having all the cookies you got from the server.
POST Request
You can send some information to a server using the post() method. The basic syntax for the request is:
(url, data={key: value}, json={key: value}, args)
Some of the important parameters are:
url – This is the URL where you want to send some data. This is a mandatory parameter.
data – This is an optional parameter that specifies a dictionary, file object or tuple you want to send to the URL.
json – This is the JSON object to be sent to the URL.
args can be any of the different named arguments, such as:
files – This is a dictionary of files for sending to the URL.
headers – A dictionary of HTTP headers to send to the specified URL.
cookies – This indicates the dictionary of cookies that you may want to send.
Just like get(), the post() method also returns a sponse object.
Wrapping Up
The python requests module tutorial above will assist you in making basic server requests. One thing to keep in mind is that the get() method is less secure than post(). This is because in get(), the parameters are passed through the URL. So, sensitive information, such as passwords may be exposed. Thus, use post() in situations where passwords or important information needs to be exchanged.
