The client side does not look like the difference, and the phenomenon that the whole system is unavailable due to single-point failure can be avoided.
As shown in fig. 3, fig. 3 is a schematic flow chart of the data search method applied to a network file system server in a data search system, where the network file system server is in communication connection with a client and a cloud storage server respectively, and the method may include:
s301: receiving a request for inquiring a next-level directory of a current directory, which is sent by a client; the request comprises path information of the current directory;
in practical application, before receiving a request for querying a next-level directory of a current directory sent by a client, a communication connection may be established with the client, and a preset root directory is sent to the client. The communication connection with the client is established, and the user may input a user name and a password at the client, and log in to a Network File System server through a third party Protocol CIFS (Common internet File System)/NFS (Network File System)/FTP (File transfer Protocol); and after the login is successful, the network file system server sends the preset root directory to the client.
S302: determining the directory level of the next-level directory according to the path information of the current directory, and judging whether the next-level directory is a file name directory or not; if the next-level directory is the file name directory, executing the step S303;
in practical application, the directory level of the next-level directory is determined according to the path information of the current directory, and whether the next-level directory is a file name directory is determined.
S303: sending a request for acquiring attribute information of a specified attribute name to a cloud storage server according to attribute information corresponding to each level of directory in the path information of the current directory; wherein, the specified attribute name is: one or more preset attribute names of file names used for generating data;
s304: acquiring attribute information corresponding to the specified attribute name returned by the cloud storage server;
