File transmission method and device based on Internet of things

Abstract

The invention provides a file transmission method and device based on the Internet of things. The method comprises the steps of receiving a login request sent by network access equipment and carrying an equipment account and an equipment password, and establishing a first long connection channel with the network access equipment after the login is authorized; receiving and storing a first file uploaded by a user terminal; generating a first index identifier corresponding to the stored first file and returning the first index identifier to the user terminal; receiving a first file transmission request sent by the user terminal and carrying the equipment account and the first index identifier; sending the first file transmission request to the network access equipment via the first long connection channel corresponding to the equipment account; receiving a download request sent by the network access equipment and carrying the first index identifier; and searching the first file corresponding to the first index identifier and transmitting the first file to the network access equipment. The file transmission method and device based on the Internet of things solve the problem that a file cannot be directly transmitted in the absence of a public network address.

Description
