Abstract
The invention provides a method for file transmission saving between terminals. A transmitting side saves a transmitted file in a transmitting side underlying buffer area and transmits the file to a receiving side underlying buffer area in fragments according to network speed; a file terminal data processing module takes out file data from the receiving side underlying buffer area; packet header and packet body data are analyzed according to the first fragment of data taken out from the file buffer area so that length and type information of the file is obtained; then a file saving linear message queue buffer area is created; finally a file saving thread is created, multiple fragments of data are acquired from the file saving buffer area, the multiple fragments of data are merged into a fragment of file data, and the fragment of file data are saved in a local file path; and multiple fragments of data are repeatedly acquired from the file buffer area and the data are merged and then locally saved until the file is completely saved. The beneficial effects of the method for file transmission saving between the terminals are that the problem of low efficiency in file receiving can be solved, and the defect of operation of frequent write-in of local data can be reduced.
Description
Technical field
The invention belongs to network communication field, particularly relate to the method that between terminal, file transfer is preserved.
Background technology
The user that develops into of network technology carries out file transfer and information interaction provides great convenience, can realize resource-sharing in tremendous range.
Along with the development of society's science and technology, use the people of mobile terminal to get more and more, the demand of people to the function of mobile terminal also gets more and more.As people not only wish the function being realized network interaction and acquisition of information by mobile terminal, also wish to carry out the functions such as file transfer by mobile terminal, along with the rise of mobile Internet, between user and user, the file transfer between terminal and terminal also becomes more and more general.But due to the disposal ability of mobile terminal, display capabilities, the restriction of bandwidth, causes file transfer not convenient, and need complicated step could realize the transmission of file, the efficiency of transmission of complex operation, file is low, and speed is slow.
Present stage, file transfer is to receiving terminal, and file is saved in local path by receiving terminal, needs to do write operation very frequently, and just can start to process next segment data after write one piece of data, causes the efficiency of file reception terminal very low.
Summary of the invention
For the deficiency that above-mentioned prior art exists, when the object of the invention is to solve reception file, the problem of inefficiency, reduces the operation of frequent write local data, is achieved by the following technical solution.
Between terminal, file transfer preserves the method realized, and wherein, described method comprises the steps:
S1, transmitting terminal send file to receiving terminal, and the file data needing to send is processed by Communication Layer bottom buffering area by transmitting terminal, and segment transmissions is to receiving terminal;
S2,
receiving terminalreceive
transmitting terminalthe file data sent, the data segment that receiving terminal receives, first leaves in receiving terminal communication buffer district;
S3, receiving terminal data processing module take out file data from communication bottom document buffering area;
S4, according to obtain file size length information, the data obtaining follow-up length length are file data;
The linear message queue buffering area that S5, establishment file are preserved;
File data in first paragraph data is put into file and is preserved buffering area by S6, receiving terminal data processing module, then continues to obtain second segment file data and puts into file preservation buffering area;
Thread preserved by S7, establishment file, preserves buffering area and obtains multiple segment data, this multiple segment data is merged into segment file data, be saved in local file path by these segment file data from file;
S8, repeat from filebuf, to obtain multiple segment data and merging data, be then saved in this locality, until this file is preserved complete.
Described receiving terminal data processing module takes out file data from communication bottom document buffering area, and according to the first paragraph Data Analysis packet header of taking out from filebuf, inclusion data, obtain file size length, type information.
The linear message queue buffering area that described establishment file is preserved, performs the principle of first in first out.
Described receiving terminal data processing module is that the file data of length is all put into file and preserved buffering area by instructing length
The present invention compared with prior art has following beneficial effect: when solving reception file, the problem of inefficiency, reduces the operation of frequent write local data.
Accompanying drawing explanation
Fig. 1 is the flowage structure block diagram of the method that between a kind of terminal of the present invention, file transfer is preserved.
Fig. 2 is the structural representation of a specific embodiment of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in detail.
As shown in Figure 1, a kind of method that between terminal, file transfer is preserved, comprising:
S1, file transmitting terminal send file to file reception end, and the file data needing to send is processed by Communication Layer bottom buffering area by file transmitting terminal, and segment transmissions is to file reception end.
S2, file reception termination receive the file data that file transmitting terminal sends.The data segment that receiving terminal receives, first can in receiving terminal communication buffer district.
S3, file receiving terminal data processing module take out file data from communication bottom document buffering area.According to the first paragraph Data Analysis packet header of taking out from filebuf, inclusion data, obtain file size length, type, etc. relevant information.
S4 is according to the file size length information obtained, and the data obtaining follow-up length length are file data.
S5 creates file and preserves buffering area, and this buffering area is linear message queue, performs the principle of first in first out.
File data in first paragraph data is put into file and is preserved buffering area by S6 file receiving terminal data processing module, then continues to obtain second segment file data and puts into file preservation buffering area ... .. length is instructed to be that the file data of length is all put into file and preserved buffering area.
S7 creates file and preserves thread, preserves buffering area and obtains multistage (25,50,100, according to performance change) data, this multiple segment data is merged into segment file data, these segment file data be saved in local file path from file.
S8 repeats from filebuf, to obtain multiple segment data and merging data, is then saved in this locality, until this file is preserved complete.
As shown in Figure 2, it is the structure chart of a specific embodiment of the method that between terminal, file transfer is preserved, in the present embodiment, the file of transmission is kept at transmitting terminal bottom buffering area by the transmitting terminal of file, network environment residing for transmitting terminal detecting or network speed, file fragmentation is transferred to receiving terminal, multistage is specifically divided into determine according to network speed, the receiving terminal of file receives multistage file and is placed on receiving terminal bottom buffering area, the terminal data processing module of file takes out file data with the data of each 1K-8K from receiving terminal bottom buffering area, according to the first paragraph Data Analysis packet header of taking out from filebuf, inclusion data, obtain file size length, type, etc. relevant information, create file again and preserve buffering area, this buffering area is linear message queue, perform the principle of first in first out, finally create file and preserve thread, preserve buffering area from file and obtain multistage (25, 50, 100, according to performance change) data, this multiple segment data is merged into segment file data, these segment file data are saved in local file path.Repeat from filebuf, to obtain multiple segment data and merging data, be then saved in this locality, until this file is preserved complete.
