Compression method and system for oversized file fragment transmission process

The invention relates to the technical field of file compression, in particular to a compression method and system for an oversized file fragment transmission process. The compression method comprises the following steps: S1, acquiring input data; s2, carrying out block division on the input data to obtain data fragments; s3, performing block compression on the data fragments after block division to obtain a plurality of compressed blocks; s4, connecting the plurality of obtained compressed blocks to obtain a compressed file and outputting the compressed file; and S4, carrying out compressed block decoding on the output compressed file to obtain decompressed data. According to the method, data compression can be effectively carried out on the pieces in the large file transmission process, so that the total size of the file in the transmission process is reduced, and the effect of increasing the overall file transmission speed is achieved. 本发明涉及文件压缩技术领域，尤其是涉及一种用于超大文件分片传输过程的压缩方法及系统。所述压缩方法，包括：S1.获取输入数据；S2.对输入数据进
