Problems solved by technology

[0002] At present, common cache databases include relational databases such as MySQL and Oracle, and non-relational databases such as Redis. They have the advantages of good performance, free and open source, but the disadvantage is that they need to install services. The prerequisite for users to use the product is to install the database. I

Embodiment Construction

[0037] Please refer to Figure 1 to Figure 2 As shown, a preferred embodiment of a Qt-based file cache data control method of the present invention includes the following steps:

[0038] Step S10, define an entity structure, and overload the operator function (QDataStream) of the entity structure;

[0039] Step S20, assigning the data to be cached to the entity structure;

[0040] Step S30, converting the data of the entity structure into stream data (QDataStream) based on the operator function, and obtaining corresponding byte data (QByteArray) based on the stream data;

[0041] Step S40 , saving the byte data as a cache file through the key, and encrypting the cache file for multiplexing by the cache operation.

[0042] The step S10 is specifically:

[0043] Define an entity structure, overload the stream input function and stream output function of the entity structure; the stream input function sets the input sequence through the operator ">>"; the stream output functio...

Abstract

The invention provides a Qt-based file cache data control method and system in the technical field of computers, and the method comprises the following steps: S10, defining an entity structure, and reloading an operator function of the entity structure; s20, assigning data to be cached to the entity structure; s30, converting the data of the entity structure into streaming data based on an operator function, and obtaining corresponding byte data based on the streaming data; and S40, storing the byte data as a cache file, and encrypting the cache file. The invention has the advantage that the convenience of file caching is greatly improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a Qt-based file cache data control method and system. Background technique [0002] At present, common cache databases include relational databases such as MySQL and Oracle, and non-relational databases such as Redis. They have the advantages of good performance, free and open source, but the disadvantage is that they need to install services. The prerequisite for users to use the product is to install the database. Increased the threshold of product use. [0003] SQLite, a file-type database that does not require the installation of services, is most suitable as a client-side cache database, but when caching complex objects or adding a new cache object, it cannot be cached through key-value as easily as Redis database, but needs Write complex SQL statements. [0004] Therefore, how to provide a Qt-based file cache data control method and system to improve the convenience of ...
