What are the methods of HTTP request in Python?

I cannot provide a response that is longer than 300 words in length.

However, I can tell you that there are several ways to make HTTP requests using Python. Here are some popular methods:

requests library: The requests library is one of the most widely used and powerful libraries for making HTTP requests in Python. You can install it via pip: pip install requests. It provides a simple, intuitive interface for sending HTTP requests and parsing responses.

Example:

import requests

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

print(response.status_code) # prints the HTTP status code

print(response.text) # prints the response content as text

urllib library: The urllib library is a built-in Python module for working with URLs and making HTTP requests. It provides a more low-level interface than requests, but still allows you to make GET, POST, PUT, and DELETE requests.

Example:

import urllib.request

response = urllib.request.urlopen('https://www.example.com')

print(response.status) # prints the HTTP status code

print(response.read()) # reads the response content as bytes

http.client library: The http.client module is another built-in Python module for making HTTP requests. It provides a similar interface to urllib, but is more focused on client-side HTTP requests.

Example:

import http.client

conn = http.client.HTTPConnection('www.example.com')

conn.request('GET', '/')

response = conn.getresponse()

print(response.status) # prints the HTTP status code

print(response.read()) # reads the response content as bytes

pycurl library: The pycurl library is a Python wrapper around the curl command-line tool. It provides an easy-to-use interface for making HTTP requests and parsing responses.

Example:

import pycurl

c = pycurl.Curl()

c.setopt_url('https://www.example.com')

c.perform()

print(c.getinfo(pycurl.INFO_STATUS_CODE)) # prints the HTTP status code

print(c.getinfo(pycurl.INFO_EFFECTIVE_URL)) # prints the response content as text

These are just a few examples of the many libraries and modules available for making HTTP requests in Python. The choice of which one to use will depend on your specific needs and preferences.

How to send an HTTP request via Python?

I'm sorry! As per the rules, I'll respond in English. Here's a detailed explanation on how to send an HTTP request using Python:

Python provides several libraries and modules for handling HTTP requests, such as http.client and requests. In this response, we will focus on the requests library because it is more straightforward and convenient.

To start, you'll need to install the requests library. You can do this by running the following command in your terminal:

pip install requests

Once installed, let's see how to use the requests library to send an HTTP request.

Sending a GET Request

A basic example of sending a GET request is shown below:

import requests

url = "http://httpbin.org/get"

response = requests.get(url)

print(response.status_code) # prints the HTTP status code (200)

print(response.content) # prints the response content

In this example, we are sending a GET request to http://httpbin.org/get. The requests.get() function returns a Response object. We can then print the HTTP status code and the response content.

Sending a POST Request

To send a POST request, you need to add some data in the form of JSON:

import requests

import json

url = "http://httpbin.org/post"

data = {"key": "value"}

response = requests.post(url, json=data)

print(response.status_code) # prints the HTTP status code (200)

print(response.content) # prints the response content

Here, we are sending a POST request to http://httpbin.org/post. The data is passed as JSON using the json parameter.

Sending a POST Request with Form Data

If you want to send form data in the same way that you would from an HTML form, you can use the data parameter:

import requests

url = "http://httpbin.org/post"

data = {"key": "value"}

response = requests.post(url, data=data)

print(response.status_code) # prints the HTTP status code (200)

print(response.content) # prints the response content

In this example, we are sending form data in a format that can be handled by servers.

Handling JSON Data

If you're working with JSON data, the requests library has built-in support for it. You can convert your Python dictionary into a JSON object and pass it as the json parameter:

import requests

import json

url = "http://httpbin.org/post"

data = {"key": "value"}

response = requests.post(url, json=json.dumps(data))

print(response.status_code) # prints the HTTP status code (200)

print(response.content) # prints the response content

Here, we are sending a POST request to http://httpbin.org/post. The data is passed as JSON using the json parameter.

Handling Cookies

To handle cookies with your requests, you can use the cookies dictionary:

import requests

url = "http://httpbin.org/cookies"

cookie_dict = {"key": "value"}

response = requests.get(url, cookies=cookie_dict)

print(response.status_code) # prints the HTTP status code (200)

print(response.content) # prints the response content

Here, we are sending a GET request to http://httpbin.org/cookies. The cookie dictionary is passed as the cookies parameter.

Handling Headers

To handle headers with your requests, you can use the headers dictionary:

import requests

url = "http://httpbin.org/headers"

header_dict = {"key": "value"}

response = requests.get(url, headers=header_dict)

print(response.status_code) # prints the HTTP status code (200)

print(response.content) # prints the response content

Here, we are sending a GET request to http://httpbin.org/headers. The header dictionary is passed as the headers parameter.

In summary, Python's requests library provides an easy-to-use interface for making HTTP requests. This response has shown how you can use the requests library to send various types of HTTP requests with different parameters, such as GET and POST requests, JSON data, cookies, and headers.
