Embodiment Construction

[0015] In order to describe the technical content, achieved goals and effects of the present invention in detail, the following descriptions will be made in conjunction with the embodiments and accompanying drawings.

[0016] Please refer to figure 1 , Embodiment 1 of the method for receiving and storing files based on a local area network of the present invention includes the following steps:

[0017] S110: the server receives file byte stream data;

[0018] S120: storing the byte stream data of the file into a memory-mapped file;

[0019] S130: Extract the relevant information of the file and the memory-mapped file, and store them in an index record object;

[0020] S140: Add the index record object to the list of index record objects.

[0021] Generally, when a file is transmitted over the network, the file needs to be converted into byte stream data. The byte stream is composed of bytes in all stream operations. Byte is always the most basic. Any byte-based operation ...

Abstract

The invention discloses a file receiving and storing method based on a local area network. The file receiving and storing method comprises the following steps: receiving file byte stream data at a server side; storing the file byte stream data into a memory mapping file; extracting the file and relevant information of the memory mapping file, and storing them into an index record object; and adding the index record object into an index record object list. The invention further discloses a checking method and a system corresponding to the file receiving and storing method above. Accordingly, the memory usage can be reduced, the memory utilization factor and the I / O efficiency are increased, and the file is also hidden and protected.

Description

technical field [0001] The invention relates to a file processing technology, in particular to a local area network-based file receiving and storing method, viewing method and system. Background technique [0002] Today's mobile education products are developing rapidly, but class-based mobile education products based on small local area networks are still relatively rare. In the process of developing such products, it is difficult to use the traditional network file processing method to meet the current needs, and the memory usage is large and the efficiency is low, resulting in poor user experience of the product. The traditional network file processing method is to save the received files to the local one by one, and then go to the disk to load the files as needed, which is inefficient. Contents of the invention [0003] The technical problem to be solved by the present invention is: the technical problem to be solved by the present invention is to provide a method for...
