The invention discloses a data acquiring method and a data acquiring device. The data acquiring method comprises the steps of receiving a file uploaded by at least one client through a first thread, storing the received file, and parsing the stored file through a second thread to acquire data contained in the file. According to the data acquiring method and the data acquiring device disclosed by the embodiments of the invention, a file uploaded by at least one client is received through a first thread, the received file is stored, and the stored file is parsed through a second thread to acquire data contained in the file. Repeated development of the file uploading function is avoided, and resources are saved. By completing file uploading and file parsing through two threads, the phenomenon of session timeout and file uploading failure is avoided effectively, and the working efficiency is improved.
