The invention provides a data file transmission method and platform. The data file transmission method comprises the steps that a data file sent by a terminal is received, the data file comprises at least one data segment, when each data segment is received, formats of the data segments are verified at the same time, the number of error messages of the received data segments in format is count-obtained, and if the number of the error messages is more than a preset number threshold, data file transmission is interrupted; when each data segment is received, the data segments are subjected to compression processing at the same time to obtain compression data segments corresponding to the data segments, and after all data segments are received, if the number of the error messages is not more than the number threshold, a CHK file of the data file is received. According to the data file transmission method and platform, a multithreading method is used, when the data file is received, the data file is subjected to verification and compression processing in real time and in a parallel mode, the method is an improvement of a data file transmission method that data files are firstly received and then processed, and data file processing efficiency is improved.
