Python Issue SSL CERTIFICATE VERIFY FAILED смотреть онлайн

Title: Python - How to Resolve "SSL: CERTIFICATE_VERIFY_FAILED" Issue
Introduction:
Python is a versatile and widely used programming language. It offers many libraries and modules to work with various internet-related tasks. However, when working with web resources, you may encounter SSL certificate verification issues, resulting in the error message "SSL: CERTIFICATE_VERIFY_FAILED." This tutorial will explain the causes of this error and guide you through resolving it with code examples.
When you perform HTTPS requests in Python, the SSL certificate of the remote server is verified to ensure secure communication. If the SSL certificate cannot be verified, Python raises the "SSL: CERTIFICATE_VERIFY_FAILED" error, preventing the connection. This error is a crucial security feature to protect against man-in-the-middle attacks.
Common causes for SSL certificate verification issues include:
The most recommended solution is to update the CA certificate bundle used by Python. This bundle contains a list of trusted root certificates for certificate verification.
You can update the bundle using the certifi library, a commonly used certificate bundle in Python. Install it if you haven't already:
Then, update the CA certificate bundle in your Python code:
Disabling SSL verification is not recommended for production applications, as it compromises security. However, for development or testing purposes, you can use the following code to bypass SSL verification:
In cases where you have custom CA certificates or want to trust self-signed certificates, you can provide a custom certificate bundle:
Here are some code examples for handling the "SSL: CERTIFICATE_VERIFY_FAILED" error:
Remember to choose the most appropriate solution based on your use case, and prioritize security in production environments.
Conclusion:
Resolving the "SSL: CERTIFICATE_VERIFY_FAILED" issue in Python is essential for secure communication. Understanding the causes and applying the appropriate solution will help you work with HTTPS resources while maintaining the integrity and security of your applications.
