Description
Technical field
The present invention relates to field of computer technology, relate in particular to a kind of file and pull method and device.
Background technology
FTP(File Transfer Protocol, file transfer protocol (FTP)) be one of agreement using the earliest at TCP/IP network with on the Internet, can apply this agreement and between two computing machines, transmit file on TCP/IP network.FTP is the agreement of application layer, and it for user's service, is responsible for carrying out the transmission of file based on transport layer.FTP is the client-server agreement of 8, can operate the file of any type and not need further processing.Although World Wide Web (WWW) has substituted most of functions of FTP, FTP remains by Internet file is copied to the conventional approach of one server from client computer, ftp client can be to the server download file of giving an order, upload file, the catalogue on establishment or change server.
Many websites of operation FTP service have mostly been opened anonymous service, and under anonymity login arranges, user does not need account just can login ftp server, and under default situations, the user name of anonymous is: " anonymous ".This account does not need password, although conventionally require input user's addresses of items of mail as authentication password, this is that some details or this addresses of items of mail are not determined, but depends on the configuring condition of database.
The method of existing ftp file transmission has following shortcoming: password and file content all use plaintext transmission, may produce the eavesdropping of not wishing generation; Database generally all can limit the maximal rate of client downloads file, causes client can not obtain fast file.
Summary of the invention
The embodiment of the present invention provides a kind of file to pull method and apparatus, uses plaintext transmission in order to solve the ftp password and the file content that exist in prior art, the problem being easily ravesdropping, and client can not be from the problem of database quick obtaining file.
