Technical Field
The invention relates to a method and a system for transmitting files of a PC (personal computer) end and an Android end, and belongs to the field of data communication.
Background
Nowadays, a smart phone is basically one hand. According to data statistics, the smart phone operating systems used by the netizens in 2021 are basically divided into an Android system, an IOS system, a Blackberry system, a Windows system and a Symbian system, and the usage ratios of the netizens are 89.6%, 33.1%, 5.3%, 8.1%, 2.3% and 1.7%, respectively. Therefore, the Android mobile phone still occupies the main part of the smart phone.
With the development of various software such as short videos and hand games, the number of files stored in the mobile phone is gradually increased, and the efficiency of transmitting a large number of small files becomes a point to be paid attention. Currently, most Android mobile phones transmit files based on an MTP protocol. The sdcard of the Android mobile phone is mounted on the PC in an MTP mode, and a virtual file system is established for the PC through an MTP protocol method. When the PC operates the files in the intelligent mobile phone, a request is sent to the intelligent mobile phone through a standard MTP protocol, and the speed of transmitting a large number of small files is very low. However, the method based on the MTP protocol has the advantages that the Android mobile phone only constructs a virtual file system to the PC to manage the mobile phone files, and the PC initiates a request to the mobile phone each time the mobile phone files are operated; the MTP can also judge whether the media file copied by the PC is supported by the target mobile phone, and the MTP supports the protection of the digital license, cannot transmit the protected file and has certain safety.
In summary, at present, there is a certain demand for managing files at the Android mobile phone side at the PC side as old, but the transmission rate of a large number of small files is slow in the prior art. With the increase of the memory of the mobile phone, the number of files stored in the mobile phone gradually increases, the requirement of people on efficient transmission of the mobile phone files cannot be met by adopting the traditional MTP (multiple time transfer protocol) mode transmission, and the problem that the transmission rate of a large number of small files is slow becomes an urgent need to be solved.

It should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments, so the following embodiments are illustrative of the present invention and are not intended to limit the scope of the present invention.
Example 1
As shown in the accompanying drawings, the embodiment discloses a file transmission method for a PC side and an Android side, which includes the steps:
the method comprises the following steps: firstly, connecting a PC end and an Android mobile phone end by using a USB data line, then starting a server Socket locally by the PC end, binding a local port, mapping the port by an adb reverse, mapping the port of the PC end to the Android end, starting the Android end APP, transmitting the mapped port as an accessory parameter to the mobile phone APP, finally starting a foreground Android Service by the Android end, starting a Socket in the Service, and connecting the Socket to the server Socket of the PC end after the starting is successful;
step two: the method comprises the steps that a user selects a copy operation, 1000 files under a directory ' sdcard/Android/1/test ' are copied to ' sdcard/Android/1/to ', the user operates at a PC end to generate request messages { ' id ': xxxxxx ', ' cmd ': copy _ file ', ' reply ': 0 ', data { ' from ': sdcard/Android/1/test ', ' to ': sdcard/Android/1/to ' }, then a text field is compressed in a GZIP mode, the load length of the text field and the number of bytes occupied by the load length are calculated, and it is judged that no multimedia file exists, and the number of bytes occupied by the load length of the text field, the load length of the text field and the content of the text field are packaged and sent;
step three: the Android end receives a message sent by the PC end, reads the high four bits of the 4 th byte, obtains the number of bytes occupied by the load length of the text field, and records the number of bytes as Y1; reading the lower four bits of the 4 th byte to obtain the number of bytes occupied by the load length of the multimedia, and recording as Y2; judging that the value of Y2 is 0, starting from the 5 th byte, reading Y1 bytes backwards, which is the load length of the text field and is marked as Y1', starting from the Y1+5 th byte, reading Y1' bytes backwards, which is the compressed content of the text field, and then decompressing to obtain the original text field;
step four: according to the read content, the Android terminal performs corresponding operation to generate a response message, and if the copying is successful, the content of a text field in the generated response message is as follows: { "id": xxxxxx "," cmd ": get _ file _ list", "code": 0 "," reply ": 1", "message": copy success ", data {" name ": test.txt", "size": 7987655 "," last _ modify ": 103243243", "file _ type": 1} }, if copy fails, the text field content in the response message is { "id": xxxxxx "," cmd ": get _ file _ list", "code": 1 "," message ": operation failure" }is generated
Example 2
As shown in the accompanying drawings, a PC-side and Android-side file transfer system of this embodiment includes: the system comprises a connection establishing module, a data packing and sending module, a data receiving and unpacking module and a response module. And the connection establishing module is used for establishing the connection between the PC end and the Android end. And the data packaging and sending module is used for packaging the data and sending the data to the Android terminal after the data is generated according to the user operation. And the data receiving and unpacking module is used for disassembling and reading the data packet sent by the PC side after the Android side receives the data packet. And the response module is used for generating a response and generating a response message after the Android terminal reads the data, and sending the response message to the PC terminal.
In the embodiments 1 and 2, when the PC sends the multimedia file, a text field is generated according to an operation, the text field is compressed, and then the load length of the text field and the number of bytes occupied by the load length are calculated. During packaging, the number of bytes occupied by the text field load length is stored in the upper four bits of the 4 th byte, the number of bytes occupied by the multimedia load length is stored in the lower four bits of the 4 th byte, and the next fields respectively store the text field length, the multimedia length, the text field content and the multimedia content in sequence. And if no multimedia file exists, the multimedia file is not stored. When the Android receives, reading the high four bits of the 4 th byte can know that several bits are needed to be read backwards from the 5 th byte to obtain the text field length, determining to read several bytes backwards according to the obtained text field length to obtain the whole text content, and obtaining the multimedia content in the MTP mode in the same way, the method needs 69s for copying 1000 small files of 1KB from one directory to another directory, and only once interaction is carried out in the sending and receiving process, and only 7s is needed for copying 1000 small files of 1KB from one directory to another directory, so that the transmission rate of the method is greatly improved, and the problem of low speed of transmitting a large number of small files between the PC end and the Android end is solved.
