Python uses Requests to handle SSL certificate validation

In Python, using the Requests library to handle SSL certificate validation requires some preparation work. Firstly, ensure that the Requests library and required dependency libraries are installed. You can install them by using pip: pip install requests Next, we need to obtain the SSL certificate to be used. You can apply for a valid SSL certificate from the Certificate authority, or you can create a self signed certificate to test. For self signed certificates, OpenSSL tools can be used to generate them. Firstly, install the OpenSSL tool: sudo apt-get install openssl Then, execute the following command on the command line to generate a self signed certificate: openssl req -new -x509 -days 365 -nodes -out cert.pem -keyout key.pem This command will generate a self signed certificate file 'certificate. pem' and a private key file 'key. pem' with a validity period of 365 days. Now that we have prepared the SSL certificate and private key file, we can use the Requests library to implement SSL certificate verification. The following is a complete example, including environment setup, code implementation, and summary: python import requests #Set the path for SSL certificate and private key files cert_file = 'path/to/cert.pem' key_file = 'path/to/key.pem' #Request to verify SSL certificate url = 'https://example.com' #Send GET request response = requests.get(url, cert=(cert_file, key_file)) #Print response content print(response.text) In the above code, we first specified the path to the SSL certificate and private key file. Then, we defined the URL to verify the SSL certificate. Finally, we sent a GET request with an SSL certificate using the 'get' method of the Requests library and obtained the response. Summary: Using the Requests library to process SSL certificate validation in Python requires the following preparatory work: installing the Requests library and related dependency libraries, and obtaining available SSL certificates. Then, use methods such as' get 'or' post 'in the Requests library to send a request with an SSL certificate and obtain a response.
