Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, fig. 1 is a first flowchart of a file processing method according to an embodiment of the application.
The file processing method provided by the embodiment of the application is applied to a server of a distributed object storage system and can comprise the following steps:
step S101: and obtaining the object to be polymerized.
In practical applications, the server may first obtain the object to be aggregated, and specifically, the server may obtain the object to be migrated from the hot storage pool as the object to be aggregated, which is not specifically limited herein.
Step S102: and determining a target encryption object in the objects to be aggregated.
In practical applications, because there may be an encrypted object in the object to be aggregated, the encrypted object needs to be specially processed due to the encryption operation, so after the server obtains the object to be aggregated, the server needs to determine the target encrypted object in the aggregated object.
Step S103: and polymerizing the object to be polymerized to obtain the target polymerized object.
In practical application, after determining the target encryption object in the objects to be aggregated, the server may directly aggregate the objects to be aggregated to obtain the target aggregation object without considering the influence of the target encryption object on the aggregation object, so as to complete the aggregation of the small objects.
In a specific application scenario, after the server obtains the target aggregate object, the server may perform operations such as storing, brushing, etc. on the target aggregate object, which is not specifically limited herein. For example, the server aggregates the objects to be aggregated to obtain a target aggregate object, and then can also judge whether the brushing condition is met; and if the brushing condition is met, writing the target aggregation object into the target storage disk.
Step S104: and storing the encryption information of the target encryption object.
In practical applications, since the target encrypted object in the aggregate object needs to be decrypted when in use, in order to accomplish this, the server needs to store the encrypted information of the target encrypted object, so as to perform the decryption operation based on the encrypted information.
It should be noted that, the manner in which the server stores the encryption information of the target encryption object may be determined according to actual needs, for example, the server may store the encryption information of the target encryption object in the form of a key value pair, and so on. In a specific application scene, a marking mode and the like can be adopted to target whether the target aggregation encryption object has the target encryption object and the like, and further, a bitmap mode can be adopted to mark whether each object in the target aggregation encryption object is an encryption object and the like, so that the attribute information of the object can be quickly known.
The application provides a file processing method, which is applied to a server of a distributed object storage system and comprises the following steps: acquiring an object to be polymerized; determining a target encryption object in the objects to be aggregated; polymerizing the object to be polymerized to obtain a target polymerized object; and storing the encryption information of the target encryption object. In the application, after the object to be aggregated is obtained and the target encrypted object in the object to be aggregated is determined, the object to be aggregated can be aggregated, namely the encrypted object can be aggregated, because the application can save the encrypted information of the target encrypted object, the target encrypted object can be decrypted based on the encrypted information, and the like, the normal use of the encrypted object can be ensured, and the file processing speed of the distributed object storage system is improved.
In the file processing method provided by the embodiment of the application, because the aggregation information is added in the head object of the object after the object is aggregated, in order to quickly save the encryption information of the target encryption object, the server can save the encryption information into the aggregation extension attribute of the head object of the target encryption object. Accordingly, the server may acquire the encrypted information from the aggregate extension attribute of the header object of the target encrypted object.
In a specific application scenario, before the server stores the encryption information in the aggregation extension attribute of the header object of the target encryption object, the server may further delete the existing data in the header object of the target encryption object. To exclude the effect of other data on the aggregate extension attribute.
In the file processing method provided by the embodiment of the application, in order to further improve the performance of the distributed object storage system, the server aggregates the objects to be aggregated, and after obtaining the target aggregate objects, the server can further aggregate the target aggregate objects with a preset number to obtain the target objects.
Referring to fig. 2, fig. 2 is a second flowchart of a file processing method according to an embodiment of the application.
The file processing method provided by the embodiment of the application is applied to a server of a distributed object storage system and can comprise the following steps:
step S201: and obtaining the object to be polymerized.
Step S202: and determining a target encryption object in the objects to be aggregated.
Step S203: and polymerizing the object to be polymerized to obtain the target polymerized object.
Step S204: and storing the encryption information of the target encryption object.
Step S205: and obtaining an object downloading request of the client.
Step S206: and determining the object to be downloaded corresponding to the object downloading request from the target aggregate object.
Step S207: the object to be downloaded is classified as an unencrypted download object and an encrypted download object based on the encryption information.
Step S208: and decrypting the encrypted download object based on the encryption information to obtain a decrypted download object.
Step S209: and transmitting the unencrypted download object and the decrypted download object to the client as target download objects.
In practical application, because the server aggregates the target encrypted objects, the encrypted objects exist in the target aggregate object, so that in order to facilitate the client to acquire the object information, the server needs to determine the object to be downloaded corresponding to the object download request from the target aggregate object after acquiring the object download request of the client, classify the object to be downloaded into the non-encrypted download object and the encrypted download object based on the encrypted information, decrypt the encrypted download object based on the encrypted information to obtain the decrypted download object, and finally transmit the non-encrypted download object and the decrypted download object as the target download object to the client.
