Description

The comparison method that the FTP packet is downloaded
Technical field
The present invention relates to the comparison method that a kind of FTP packet is downloaded, particularly relate to a kind of comparison method of downloading to the FTP packet of wireless communication module.
Background technology
FTP is that the English of File Transfer Protocol (FTP) is called for short, and Chinese abbreviates " literary composition passes agreement " as, is used for the transmitted in both directions of the control documents on the Internet.Simultaneously, it also is an application program (Application).The user can link to each other a large amount of programs and information on the access server to oneself PC with all servers that move File Transfer Protocol all over the world through it.The main effect of FTP; Letting the user connect a remote computer (moving the ftp server program on these computers) exactly watches remote computer which file is arranged; Copy local computer to file from remote computer then, or deliver to remote computer to the file of local computer.Because FTP develops widely, increasing wireless communication module begins to support the FTP function.But wireless communication module is as the M2M product, and the form that can not preserve into a file to the data that FTP obtains can only be exported from serial ports as data.And that the downloaded files type has is varied; There is text that binary file is also arranged; Some need could be read by instruments such as UE; Some ftp server can add ESC with data downloaded, and the correctness of downloading through manual work comparison checking like this can prolong the testing time, and the efficient of manual function's test is quite low.
Summary of the invention
The technical problem that the present invention will solve is in order to overcome the defective that artificial comparison can prolong the testing time in the prior art, testing efficiency is low, the comparison method that provides a kind of automatic FTP packet to download.
The present invention solves above-mentioned technical problem through following technical proposals:
The comparison method that a kind of FTP packet is downloaded, its characteristics are that it may further comprise the steps:
S 1, set up being connected of wireless communication module and PC, confirm that AT order communication is normal;
S 2, configuration FTP GET functional test parameter, and needing downloaded files to be configured to file 1;
S 3, carry out the FTP download function, the content that serial ports is obtained is stored as file 2 through the capturing function of WINDOWS hyper terminal;
S 4, traversal file 2, the character in the file 2 is changed, form file 3, so that file 3 is the character on the identical platform with character in the file 1;
S 5, traversal file 1 and file 3, output test result, it is identical and different to be divided into file.
Preferably, step S 4In, open file 2 with binary mode, begin from first byte of file 2, in case find the existence of 0x0D 0x0D 0x0A, just convert the form of 0x0D 0x0A to, form file 3 at last.
Preferably, step S 5Also comprise the steps: before with binary form open file 1 with file 3, obtain the size of file 1 and file 3, at first if the comparison document size inequality, representes that then file size is different, shows that the data in two files are also just different.
Preferably,, then, relatively arrive the end of file always,, then write down and point out discrepancy if find byte inequality since first byte comparison of two files if file size is identical.
Positive progressive effect of the present invention is: this comparison method can be used for FTP packet download back and the original packet compares; And provide the result; Thereby reference frame as the FTP functional test of wireless communication module; The correctness of subtest FTP download function has promoted the efficient of functional test.
Description of drawings
Fig. 1 is the flow chart of preferred embodiment of the present invention.
Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to specify technical scheme of the present invention.
Present embodiment is explained the method for automatic comparison FTP data download bag correctness on the WINDOWS platform, to be embodied as example.Certainly, comparison method of the present invention is not limited to the realization on the WINDOWS platform, and those skilled in the art should know, and the present invention is equally applicable to other operating system platforms, such as the realization on the platforms such as Linux.Following mask body is introduced idiographic flow of the present invention, and is as shown in Figure 1.
Step 101 is connected through Serial Port Line wireless communication module with PC, set up the communication port between PC and the module, confirms that AT order communication is normal.
Step 102, the GET functional test parameter of configuration FTP is such as the path of server, user name, password or the like.Be configured to 1.dat to the needs downloaded files then, 1.dat only is that the file of also configurable other extension name of one-tenth is such as forms such as txt, gif, bin or jpg for example here.
Step 103 is carried out the FTP download function, and the content that serial ports is obtained is stored as 2.dat through the capturing function of WINDOWS hyper terminal;
Step 104; Consider because the residing platform of ftp server is different; Such as LINUX and local platform; Such as the difference of WINDOWS platform, usually the 0x0A character on LINUX can be become 0x0D 0x0A by the WINDOWS escape, needs therefore to remove that ftp server obtains data and the otherness that causes.Method is to open file with binary mode, and obtains file size, begins from first byte of file, in case find the existence of 0x0D 0x0D 0x0A, just converts the form of 0x0D 0x0A to, forms 3.dat at last.
Step 105 is opened 1.dat and 3.dat with binary form, and obtains file size.
Step 106, at first if the comparison document size inequality, representes that then file size is different, data are also just different certainly like this.
Step 107 if file size is identical, then begins comparison from first byte, relatively arrives the end of file always.If find byte inequality, then write down and point out discrepancy, write down byte location inequality.
Step 108, last, no matter be the identical or difference of file, all output test result, it is identical and different to be divided into file.
Wherein, step 104-108, those skilled in the art can adopt known programming technique, develop an executable program, when test, utilize this executable program just can realize automatically than right.The benefit of doing like this is: 1, will could read by the UE instrument originally, and need tester's time spent energy long, that expend big, and occur mistake unavoidably.The situation of 2, for some server data downloaded having been added ESC, the present invention can eliminate the otherness of platform automatically, and compares, with correctness and the lifting testing efficiency that guarantees comparison.
Though more than described embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is limited appended claims.Those skilled in the art can make numerous variations or modification to these execution modes under the prerequisite that does not deviate from principle of the present invention and essence, but these changes and modification all fall into protection scope of the present invention.
