Method and device for controlling access

Abstract

The invention discloses a method and a device for controlling access, and relates to the field of resource management. A specific embodiment of the method comprises the following steps: receiving an access request sent by a client, and searching one or more first flow configuration parameter values and / or one or more control parameter values matched with an access resource positioning identifier of the access request from custom configuration information; constructing a control flow strategy corresponding to the access request; and releasing or prohibiting the access request according to a flow control strategy. By customizing configuration information, the flexibility of determining configuration parameters and the flexibility of managing and controlling access granularity are improved; by dynamically constructing the control flow strategy, the problem that the flexibility is poor due to the fact that configuration files or codes need to be modified in order to modify the control flow strategy in an existing method is solved, the problem that a system needs to be restarted in order to modify configuration information in the existing method is solved, and the flexibility and efficiency of flow control are improved.

Description

technical field [0001] The invention relates to the field of resource management, in particular to a method and device for controlling access. Background technique [0002] In distributed systems of various business types, the system needs to maintain stability and high availability under high concurrency conditions. At present, system stability and high availability can usually be achieved by controlling the flow of access requests (current limiting). [0003] The current method for controlling the flow of access requests usually uses setting configuration files or codes to specify a control strategy for setting user information (such as user ID, user IP address, etc.). When some business scenarios need to modify the control strategy (such as adding or modifying control parameters), it is necessary to modify the existing setting configuration files or codes, and the system needs to be restarted to make the modified control strategy take effect; it can be seen that the exist...
