Embodiment 1

[0059] Please refer to figure 1 , is a schematic diagram of the hardware environment of the file transfer method of an embodiment. In the hardware environment composed of the server 102 and the terminal 104, the server 102 is connected to the terminal 104 through a network. The above-mentioned network includes but is not limited to: a wide area network, a metropolitan area network network or local area network, the terminal 104 is not limited to PCs, mobile phones, tablet computers or other mobile terminal devices. The file transfer method in this embodiment may be executed by the server 102, may also be executed by the terminal 104, and may also be executed jointly by the server 102 and the terminal 104. Wherein, the file transfer method performed by the terminal 104 in the embodiment of the present invention may be performed by a client installed on the terminal 104 .

Embodiment 2

[0087] Please refer to Figure 4 , is a schematic diagram of a model architecture of a file transfer method in an embodiment, and is used for implementing the file transfer device of the above file transfer method, and the device may include:

[0088] The response unit 41 is configured to obtain a target file to be transmitted by the user in response to the file transmission request sent by the user; segment the target file to obtain several segments of the target file.

[0089] The verification unit 42 is used to verify all fragments of the target file to the server; for any fragment, if the browser verifies that the fragment already exists in the server, the fragment is marked as transmitted, otherwise, if the browser If the fragment does not exist on the verification server, the fragment is marked as not transmitted.

[0090] The sending unit 43 is configured to transmit the fragments marked as not transmitted to the server, so that the server merges the existing fragments...

Embodiment 3

[0093] Please refer to Figure 5 , is a schematic flowchart of a file transmission system in another embodiment, the file transmission system includes a sending unit and a receiving unit, and the method includes the following steps:

[0094] Step 301 The sending unit compares the size of the pre-uploaded target file with a preset value.

[0095] Step 302 If the size of the target file is smaller than the preset value, the sending unit sends verification information to the receiving unit to verify whether the receiving unit has the target file.

[0096] Step 303 The receiving unit compares the verification information to confirm whether the target file exists.

[0097] Step 304: The receiving unit sends confirmation information to the sending unit.

[0098] Step 305: The sending unit ends the transmission request after receiving the confirmation information that the receiving unit exists the target file.

[0099] Step 306: The sending unit receives the confirmation informati...

Abstract

The invention relates to file transfer technologies for the field of Internet, in particular to a browser-based file transfer method and device. In response to a file transfer request sent by a user,a browser carries out fragmentation on a target file and respectively transfers all fragments, and all fragment files are finally reintegrated into the transferred file, so that the problem that a large file needs to be retransferred after a transfer failure is solved. The method and device provided by the invention is applicable for large file transfer among multiple browsers and among multiple browser versions, is particularly applicable to a multi-operation system environment of government agencies or large enterprise information departments, adopts file fragment uploading, and totally supports an application client clustering or load balancing environment, so that high efficiency and a high success rate of large file uploading on the browser are ensured.

Description

technical field [0001] The invention relates to file transmission technology in the Internet field, in particular to a browser-based file transmission method and device. Background technique [0002] With the popularization of the network and the improvement of business complexity, the need to transfer files has become more and more common and important. Even the nuclear power industry has higher and higher requirements for file interaction systems. However, based on safety considerations, computers actually used in the nuclear power industry are relatively slow to update both hardware and software, and computer equipment and software will be added and updated in different periods. In this way, the file transfer environment becomes more and more complicated and difficult, especially the transfer of large files. The World Wide Web or local area network basically transmits files through a browser. A browser refers to a software that can display the content of HTML files (an a...
