An error occurred while accessing redis using python on the local machine (windows) today. There are two types of errors: If I configure sentinel, an error such as unknowncommandSENTINEL will be reported; if I configure StrictRedis, NOAUTHAuthenticationrequired will be reported .... an error occurred while accessing redis using
Here we will bring you the Python Flask framework application to call the Redis queue data method, so as to achieve asynchronous and non-blocking, so as to improve the performance of some programs in real-time processing. For more information, see
