In an underlying distributed storage system or cloud storage system of an insurance system, generally, a plurality of tenants exist under a root authority, each tenant corresponds to a plurality of buckets for storing various types of data objects, the tenant may correspond to a certain type of large department in the insurance system, the bucket may correspond to a middle-level department in the insurance system, a logical bucket pair may correspond to a data storage server, for example, a file server using an s3 interface, the bucket may include multiple types of application data or various types of subsystem storage data, and each department may be considered as a specific business scenario.
The invention relates to a unified interface processing method, a device, equipment and a medium for multiple storage media, which are mainly applied to a scene that different storage media cannot be accessed through a unified interface in distributed storage of an insurance system, and are combined with a basic flow schematic diagram of the unified interface processing method for the multiple storage media shown in a figure 1(a) and a system architecture schematic diagram shown in a figure 1(b), wherein the method comprises the following steps:
in step 110, defining a unified interface based on a plurality of interfaces of a bucket, wherein the unified interface is installed in a logic bucket, the logic bucket corresponds to a logic concept of the bucket, and the unified interface is used for providing services according to a software development kit;
the barrel belongs to the subordinate concept of the tenant, a plurality of barrels can exist under one tenant, and one barrel can be used for storing one special data, and can be the same medium or formed by combining different storage media.
When a bucket is formed by combining a plurality of storage media, each storage medium of the bucket corresponds to an application interface for data access, and the application interfaces of the plurality of storage media of different buckets in an insurance system are defined, so that a logically uniform interface is formed, and the uniform interface can realize functions realized by various types of application interfaces, such as picture processing, video processing, monitoring service, authority service, index service, file transmission, file asynchronous service, electronic document service and the like.
The unified interface can shield the difference of multiple storage medium interfaces at the bottom layer through a set of logical virtual storage architecture, so that the upper layer application has no perception on the difference between the storage medium interfaces, and the file storage of different storage media can be realized by directly calling the unified interface provided by the content management system.
In the specific implementation manner of the exemplary embodiment of the present invention, in an object storage manner, an interface protocol of logical S3 is simulated, and concepts of logical tenants and buckets are simulated, a set of logical APIs is provided, and services such as permission, monitoring, indexing, file transfer, picture processing, video processing, and the like are implemented, so that a set of virtual logical storage architecture is constructed, and the storage adaptation engine in fig. 1(b) can be used for write switching of a unified interface to different storage media when a failure occurs. The invention respectively realizes the functions of uploading, downloading and the like of various storage media aiming at different storage media.
In step 120, receiving request information of an application party through the unified interface, where the request information at least includes one of a permission information token, a file ID, or a logic bucket, and the request information includes an uplink request and a downlink request;
as shown in fig. 2, this process specifically includes the following steps:
step 101: the application side transmits the token carrying the authority information, the file flow, the logic bucket and other parameters together and receives an uploading instruction of the application side;
the file upload operation may occur in a variety of scenarios, including a page Restful API, i.e., a uniform interface request, and various SDKs, i.e., software development kit requests.
The barrel names carried by the application side during uploading are logical barrels in a logical meaning, and one logical barrel corresponds to a plurality of storage barrels. The invention supports write-once read-many function of the storage bucket, namely, the logic bucket only corresponds to one storage bucket used for write operation, but can carry out read operation on a plurality of related storage buckets. Therefore, when the storage barrel is changed, the invention only needs to modify the configuration to make the logic barrel associated with the new storage barrel, and can realize the switching of the barrel for writing operation, and the application side still uses the original logic barrel name to perform reading/writing operation without any modification.
When uploading, the application side needs to transmit the required service index in addition to the parameters necessary for the uploading interface, and uses the index service for recording for subsequent retrieval, statistics and other scenes.
Step 102: analyzing token information of an application party for authentication;
and calling the authority service to authenticate the application party and checking whether the logic bucket has the authority of uploading the file. If the authentication is successful, calling a file transmission service to upload; and if the authentication fails, returning an error report.
Step 103: uploading the file;
in one implementation of the exemplary embodiments of this invention, the method further comprises:
after the request information is analyzed, reading operation is carried out on other buckets except the bucket corresponding to the request information, namely, a storage bucket which is used for writing operation and corresponds to the current logical bucket is found through configuration, according to a storage medium of the storage bucket, the invention calls an uploading interface supporting the storage medium, records the information of the storage medium and the information of the logical bucket as system indexes, and writes a file into a correct storage bucket, and the specific process is as follows:
when the service index carried by an application side during uploading does not exceed 2KB, writing the file, the service index and the system index into corresponding storage, then calling an index service, recording the service index and the system index into an elastic search, and using the elastic search for subsequent query, statistics and other functions;
and writing the file and the system index into a corresponding storage when the service index carried by the application side is more than 2KB, then calling an index service, and recording the service index and the system index into an Elasticissearch for subsequent query, statistics and other functions.
Step 104: returning data information such as a file success identifier, a file ID and the like to the application party;
it can be seen from the foregoing embodiments that, the method for implementing file upload provided by the present invention implements shielding differences between upload interfaces of multiple storage media on the bottom layer by constructing a set of logical virtual storage architecture, so that an application party can invoke the upload function of the present invention without perception, implement file storage of various storage media, and do not need to perform customized development on different storage media, thereby enabling development of an upper application system to be simpler and more uniform.
The invention also provides a file downloading method of the differential shielding of the multiple storage medium interfaces. Fig. 3 is a schematic view of a download function flow of a differential shielding of multiple storage medium interfaces according to the present invention.
In step 130, the request information is parsed to perform corresponding data operations on the bucket corresponding to the request information.
Parsing includes parsing tokens, filestreams, logical buckets, and other parameters in the request information to implement the file operation corresponding to a specific request, and is not limited to a write operation.

The upper application system can realize file uploading/downloading operation on different storage media by calling the virtual logic storage function, thereby realizing shielding of differentiation of interfaces of multiple storage media.
In addition, the invention can better adapt to various commercial hardware, shield the influence and pressure on the application caused by the change in purchase, and avoid the modification of an upper application system caused by the change of the hardware; when a certain storage device is in failure, the storage medium can be immediately switched through the uniform interface in a short time, so that the stable operation of production is ensured; the system can be reasonably distributed and used according to the performances of different commercial hardware, and is provided with different service scenes; the development of the upper application system is simpler, more uniform and more convenient.
In an implementation manner of the exemplary embodiment of the present invention, the method for implementing file downloading further includes: authenticating the authority information token, and executing the operation corresponding to the request information after the authentication is passed, which specifically includes the following steps, with reference to fig. 3:
step 201: the application side transmits parameters such as a token carrying the authority information, a file ID, a logic bucket and the like together, and receives a downloading instruction of the application side;
the file download operation may occur in a variety of scenarios, including a page Restful API request and various SDK requests.
Step 202: analyzing token information of an application party for authentication;
step 203: downloading the file;
the file ID and the logic bucket are inquired through the index service, the corresponding storage bucket is found, and according to the storage medium of the storage bucket, a download interface supporting the storage medium is called to acquire the file stream.
Step 204: returning the required file stream to the application side;
it can be seen from the foregoing embodiments that, the file download implementation method provided by the present invention implements shielding of differences between download interfaces of multiple underlying storage media by constructing a set of logical virtual storage architectures. Therefore, the application side can download and retrieve the files stored in various storage media, the work that the application side needs to carry out data migration due to the replacement of the storage media is avoided, the development of the application side is facilitated, and meanwhile, the risk of loss of production data is reduced.
When the application side provides an interface for calling the uploading/downloading of the invention, the virtual logic storage constructed by the invention realizes the related functions of file storage according to the parameters transmitted by the upper system and the system index information. The application side can realize the uploading/downloading operation of different storage media by calling the uniform uploading/downloading interface.
