Example Embodiment

[0035] In order to make the purpose, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

[0036] As mentioned above, the prior art has security problems. In addition, the prior art also has other problems. For example, the process of transmitting pictures needs to consume the paid network traffic of the mobile devices of both users; when the amount of data of the pictures is large, the transmission takes more time; the cloud disk itself may requir...

Abstract

The application discloses a file transmission method and device which are used for solving a problem of a relatively high data leakage risk of a mode of transmitting images between mobile devices by a cloud disk in the prior art. A first client and a second client are positioned in the same local area network. The method comprises the steps that: the first client acquires address information of a built-in server of the first client in the local area network; the first client generates a DOI including the address information according to the address information, so that the second client sends a file to the built-in server by scanning the DOI; and the first client acquires the file received by the built-in server.

Description

technical field [0001] The present application relates to the field of network technology, in particular to a file transmission method and device. Background technique [0002] With the popularity of mobile devices, users increasingly share various files through mobile devices (such as mobile phones, tablet computers, smart watches, etc.), and this sharing is realized based on file transfer. [0003] Pictures are one of the most common types of files that users transfer. For example, in some commercial operations, merchants require users to provide pictures in their mobile phones for verification or other purposes. Assuming that merchants provide users with a free photo printing function, users are required to provide photos to be printed in their mobile phones. [0004] In the prior art, users usually transmit pictures indirectly through cloud disks in the Internet. Assuming that user A wants to transfer the pictures in his mobile phone to user B, user A can connect his m...
