Requests - Overview
Requests is a HTTP library that provides easy functionality to deal with http request/response in your web application. The library is developed in python.
The official website of Python Requests which is available at https://2.python-requests.org/en/master/ defines Requests as follows −
Requests is an elegant and simple HTTP library for Python, built for human beings.
Features of Requests
The features of Requests are discussed below −
The python requests library has easy to use methods available to handle Http request. Passing of parameters and handling the request type like GET, POST, PUT, DELETE, etc. is very easy.
You can get the response in the format you need and the supported ones are text format, binary response, json response, and raw response.
The library allows you to read, update or send new headers as per your requirements.
Timeouts can be easily added to the URL you are requesting using python requests library. It so happens that you are using a third-party URL and waiting for a response.
It is always a good practice to give a timeout on the URL as we might want the URL to respond within that timeout with a response or an error that is coming because of timeout. Not doing so can cause either to wait on that request indefinitely.
The requests module gives support for error handling and some of which are Connection Error, Timeout errors, TooManyRedirects, Response.raise_for_status errors, etc.
The library allows you to read, write and update for the requested URL.
To maintain the data, you require between requests you need sessions. So, if the same host is called again and again you can re-use the TCP connection which in turn will improve the performance.
SSL certificate is a security feature that comes with secure urls. When you use Requests, it also verifies SSL certificates for the https URL given. SSL Verification is enabled by default in the requests library and will throw an error if the certificate is not present.
HTTP authentication is on the server-side asking for some authentication information like username, password when the client requests a URL. This is an additional security for the request and the response being exchanged between the client and the server.
Advantages of using Python Requests Library
Following are the advantages of using Python Requests Library −
- Easy to use and fetch the data from the URL given.
- Requests library can be used to scrape the data from the website.
- Using requests, you can get, post, delete, update the data for the URL given.
- The handling of cookies and session is very easy.
- The security is also taken care of the help of authentication module support.
