(As we all know, the official website of Bing Search will update a high-quality background image every day. Many students want to call in the interface,
But the Bing server is not particularly stable in China (>500ms). Bing-upyun can upload daily Bing pictures to Youpaiyun,
Provide an interface that supports image processing and backtracking (direct connection to the cloud is also adopted, and the actual measurement takes about 300ms from request to completion of receiving images, depending on network conditions)
And can choose to deploy an elegant front-end page. At present, there are many excellent Bing daily picture interfaces, which can store pictures locally on the server and provide calling interfaces, but most of them need to run permanently in the background. In addition, there is currently almost no similar interface for using cloud storage pictures. Hence this project.)
