Abstract

The invention relates to a resource access method, device and system, electronic equipment and a storage medium, and relates to the field of cloud computing. According to the technical scheme, the detection code is injected into the client, and the abnormity of the access CDN node is monitored by checking the response message. And when the CDN access node is abnormal, the application server switches resource access to a source server serving as a CDN data source, and directly pulls resources from the source server. Thus, the situation that the CDN side is difficult to detect access exception of individual users and cannot timely and effectively solve the exception problem is avoided, and the client can timely discover the access exception and automatically switch resource access to the source server so as to ensure that the users can timely, safely and reliably access resources.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a resource access method, device, system, electronic equipment and storage medium. Background technique [0002] In order to solve network congestion and improve the response speed and success rate of users accessing the network, a content delivery network (Content Delivery Network, hereinafter referred to as CDN) emerges as the times require. At present, CDN technology is widely used in Internet applications. Developers store static resources such as pictures, multimedia materials, and Cascading Style Sheets (CSS), which occupy large resources, in CDN nodes located around the world. When a user requests a resource, the resource cached by the nearest CDN node is returned, which greatly reduces the pressure on the source server and improves user experience. [0003] However, the use of CDN still has certain risks. Since CDN resources exist in third-party servers,...
