The zookeeper is a distributed application program coordination service with open source codes, is an open source implementation of Chubby of Google, and is an important component of Hadoop and Hbase. zookeeper is software that provides a consistent service for distributed applications, and is mainly used to solve some data management problems often encountered in distributed applications, such as: unified naming services, state synchronization services, cluster management, management of distributed application configuration items, and the like.
When the method is specifically implemented, an access request sent by a user is received, and the address of the user is determined according to the access request.
And after the address of the user is determined according to the access request, determining whether the user is in a zookeeper white list or not according to the address of the user.
And if the user is in the zookeeper white list, forwarding the access request to the corresponding service microservice, and successfully verifying the authority.
If the user is not in the zookeeper white list, reading the authority data of the user from the zookeeper according to the address of the user, and if the address of the user is determined to be legal according to the authority data of the user, forwarding the access request to the corresponding service microservice, wherein the authority verification is successful; and if the address of the user is determined to be illegal according to the authority data of the user, the authority verification fails, the user is refused to access, and the verification is finished.
The white list refers to an accessible user address set list, and the authority data of the user is stored in a user node in the zookeeper. Therefore, the distributed application permission verification method in an embodiment of the present invention shown in fig. 2 further includes, on the basis of fig. 1:
step 201: creating a user node and a white list in the zookeeper according to the address of the user;
