Pycurl
pycurl
is a Python interface to the libcurl library, which is a widely used client-side URL transfer library supporting various protocols. With pycurl
, you can perform HTTP, HTTPS, FTP, and other types of network requests in Python.
Here are some key features and functionalities of pycurl
:
-
Protocol Support: It supports a variety of protocols, including HTTP, HTTPS, FTP, FTPS, SCP, SFTP, LDAP, and more.
-
Performance:
pycurl
is known for its high-performance capabilities, making it suitable for handling large volumes of network requests efficiently. -
Features:
pycurl
supports many features like HTTP POST, GET, PUT, DELETE requests, handling cookies, custom headers, file uploads, and more. -
Asynchronous Support:
pycurl
provides support for asynchronous network requests using callbacks. -
Security: It allows you to enable or disable SSL/TLS certificate verification to control security measures.
-
Multi-threading Support: You can use
pycurl
within multi-threaded environments to perform concurrent network operations.
Here’s a simple example of how to use pycurl
to make an HTTP GET request:
import pycurl
url = "https://www.example.com"
# Create a new curl object
curl = pycurl.Curl()
# Set the URL to fetch
curl.setopt(curl.URL, url)
# Set the SSL certificate verification options (optional)
curl.setopt(curl.SSL_VERIFYPEER, 1)
curl.setopt(curl.SSL_VERIFYHOST, 2)
# Buffer to store the response
response_buffer = bytearray()
# Set the WRITEFUNCTION to handle the response
curl.setopt(curl.WRITEFUNCTION, response_buffer.extend)
# Perform the request
curl.perform()
# Get the HTTP response code
http_response_code = curl.getinfo(curl.RESPONSE_CODE)
print(f"HTTP Response Code: {http_response_code}")
# Get the response body
response_body = response_buffer.decode("utf-8")
print(f"Response Body: {response_body}")
# Close the curl object
curl.close()
Make sure to have pycurl
installed in your Python environment before running the above code. You can install it using pip
:
pip install pycurl
Please note that pycurl
is a lower-level library compared to higher-level alternatives like requests
, so it might require a bit more boilerplate code. However, it can be a suitable choice when you need more control over network operations or when dealing with specific use cases not fully covered by higher-level libraries.
