File transfer system and method of instant message

Abstract

The invention discloses a document transmission system and method for instant message. The method comprises that from a first instant message client end, one or more second instant message client endsare chosen from a contact person list, and documents are chosen to be transmitted directly; the document transmission request from the first instant message client end is received by an instant message application module, and reassigned to a document transmission service module for processing which receives the document uploaded by the first instant message client end and informs the instant message application module that the reception is finished. The instant message application module establishes the document access authority of the second instant message client end through a mutually usedauthentication database, and when the second instant message client end receives the document download link notice from the instant message application module, and links the document transmission service module, the document transmission service module judges the document download authority of the second instant message client end, and decides whether to download the documents. The invention realizes the document transmission in the process of instant message group chat or the document transmission that is initiated by contact persons.
