Sending HTTP Requests with Python Requests Library

The Python Requests Library simplifies the process of making HTTP requests. With this library, you can perform GET, POST, PUT, DELETE, and other HTTP methods effortlessly. To send an HTTP request, use methods like requests.get(url, params) or requests.post(url, data, params). These methods allow you to interact with servers, submit forms, download files, set timeouts, and more.

For example, you can include custom headers using the headers parameter, send cookies with the cookies parameter, or provide authentication credentials with the auth parameter. Below is an example of a GET request with a custom HTTP header to the ReqBin echo URL. Click Execute to run Python HTTP Requests examples online and view results.

What is the Python Requests Library?

The Python Requests Library is one of the most popular tools for making HTTP requests. It provides a straightforward API for interacting with web resources, making it simple to send GET, POST, DELETE, and other requests.

Key features include:

• SSL certificate validation.
• Support for international domain names.
• Handling of session cookies.

Although not included in the standard Python distribution, Requests is widely used because it simplifies HTTP interactions, making the code shorter and more readable.

How to Install the Python Requests Library

To install the Requests Library, use the pip package manager:

pip install requests

After installation, import it into your code:

import requests

Common HTTP Methods with Python Requests

1. Sending HTTP GET Requests

Use GET requests to fetch data from a server. GET requests are:

• Cacheable.
• Bookmarkable.
• Stored in browser history.

Example:

response = requests.get("https://example.com")

2. Sending HTTP POST Requests
POST requests allow you to send data, such as forms, JSON, or files, to the server. These requests are:
•	Not cacheable.
•	Not stored in browser history.
•	Useful for updating or creating resources.
Example:

response = requests.post("https://example.com", data={"key": "value"})

3. Sending HTTP PUT Requests

Use PUT requests to replace or update existing resources on a server. These requests are not cacheable or bookmarkable.

Example:

response = requests.put("https://example.com/resource", data={"key": "new_value"})

4. Sending HTTP DELETE Requests

DELETE requests are used to remove resources from a server. They are neither cacheable nor stored in browser history.

Example:

response = requests.delete("https://example.com/resource")

5. Sending HTTP HEAD Requests

HEAD requests are similar to GET requests but retrieve only the headers, not the response body. They are useful for checking metadata.

Example:

response = requests.head("https://example.com")

6. Sending HTTP PATCH Requests

PATCH requests allow partial updates to existing resources. They are faster and less resource-intensive than PUT requests.

Example:

response = requests.patch("https://example.com/resource", data={"key": "partial_update"})

7. Sending HTTP OPTIONS Requests

OPTIONS requests are used to query the communication options available for a resource. This is commonly used for CORS (Cross-Origin Resource Sharing).

Example:

response = requests.options("https://example.com")

The Python Requests Library provides a robust, easy-to-use interface for handling HTTP requests. Whether you’re fetching data, uploading files, or managing resources, it simplifies complex HTTP interactions. By understanding its features and the various HTTP methods, you can efficiently integrate web services into your Python projects.
