Judging the browser type in JS is probably a problem that every developer who edited the page has encountered. Among many browser products, ie, Firefox, opera, Safari ........ many brands have different standards. Therefore, you often need to perform different operations based on different browsers or even different versions of the same browser.

object-based storage technology is emerging as a foundation for building large scale storage systems. It leverages existing processing technologies, network technologies, and storage components to achieve unprecedented scalability and throughput in a simple and convenient way.At the heart of this architecture is the object, which is the basic container that holds the application data and an extensible storage attribute. Traditional files are decomposed into a series of storage objects and distr
