An HTTP request is a message sent by a client (such as a web browser) to a server, following the rules of the HTTP Protocol. Users use it to request specific resources or perform actions on the server. In Python, you can work with HTTP requests by requests library.
Here's an overview of how Python HTTP requests are using the requests library:
- Install the requests library.
- Import requests module.
- Send an HTTP GET request.
- Send other types of HTTP requests.
HTTP supports several types of requests, each serving a different purpose. Here are the commonly used types of HTTP request methods:
- You use the GET request to retrieve data or resources from a server. It is a safe and idempotent operation, meaning it should not modify any server state. It sends the request parameters as part of the specified URL.
- The client uses the POST request to send data to the server for creating or modifying resources. Repeated identical POST requests may result in different outcomes. The request body sends the data.
- You use the PUT request to send data to the server to update or replace an existing resource. It replaces the entire resource with the data provided in the request. Like POST, it is not idempotent.
- The client sends form data to the server using the PATCH request. This updates an existing resource partially. It applies changes to the resource rather than replacing it entirely. The request body contains only the changes to be made. Like POST and PUT, it is not idempotent.
- The client uses the DELETE request to request the server to delete a specified resource. It removes the resource from the server. It is not idempotent.
- The HEAD request is like GET but only retrieves the response headers.
When you make an HTTP request, you can add different parameters to customize it and give more details. The main parameters include the URL, request method, headers, and request body. In Python, you can make HTTP requests in different ways.
You can make HTTP requests in two ways:
- Use the built-in http.Client library or
- Create custom HTTP clients with external libraries.
There are several ways to make HTTP requests:
- Built-in HTTP.Client,
- requests library,
- python-requests libraries, and
- Custom HTTP clients.
HTTP requests are an integral part of interacting with web servers and APIs. Python provides different options for executing HTTP requests, each with its characteristics.
Here the example of How to use Requests to make a simple HTTP GET request.
