Python Requests Module Self Signed Certificate

If you use Python requests module to make HTTP requests to a server with a self-signed SSL certificate, the verification of the certificate will fail by default. This happens because the certificate is not issued by a trusted certificate authority.

However, there are ways to make requests ignore the SSL certificate error and continue with the request without verifying the certificate.

Option 1: Verify=False

The easiest way to ignore the SSL certificate error is to pass verify=False parameter in requests.get() method.

import requests
response = requests.get('https://example.com', verify=False)
print(response.content)

By passing verify=False, you are telling requests to ignore the SSL certificate and continue with the request. This is not recommended for production use, as it exposes your application to security vulnerabilities.

Option 2: Provide the CA Certificate

If you have the CA certificate that signed the server's SSL certificate, you can pass it to requests module to verify the SSL certificate.

import requests
response = requests.get('https://example.com', verify='/path/to/ca_certificate.pem')
print(response.content)

By providing the CA certificate, requests will be able to verify the SSL certificate and establish a secure connection with the server.

Option 3: Disable SSL Verification Globally

If you want to disable SSL verification for all requests made by your Python application, you can use the following code snippet:

import requests
requests.packages.urllib3.disable_warnings()
response = requests.get('https://example.com')
print(response.content)

This code disables SSL certificate verification globally for all requests made by your Python application. This is not recommended for production use, as it exposes your application to security vulnerabilities.
