Example IV
Fig. 4 is refer to, the present embodiment is a concrete application scene of above-described embodiment.
The present embodiment is related to browser component 21, data extraction APP22, wireless routing device assembly 11, hijacking data component
12nd, DNS service component 13, HTTP service component 14 and data extract totally seven components of serviced component 15.Wherein, browser component
21 and data extraction APP22 operates in mobile terminal 2, wireless routing device assembly 11, hijacking data component 12, DNS service component
13rd, HTTP service component 14 and data extraction serviced component 15 operate in equipment end 1.Equipment end 1 and multiple mobile terminals 2 are wireless
Communicate to connect (Fig. 4 is exemplified by connecting two mobile terminals), and with a move media 3 (can also be mobile terminal) cable modem
Letter connection.
What it is by Wi-Fi connection equipment end can be multiple Android phones, and by USB wired connections all the way, can access
Other types mobile phone or move media.Wherein, for data extraction service component as public module, common is Wi-Fi and USB two
Kind data extracting mode service.
It is following that seven above-mentioned components are illustrated respectively：
Can be any browser on mobile phone for browser component, it is clear that the component for Android phone provides webpage
Look at service.
For wireless routing device assembly, it can be offered wireless internet services for target mobile phones, the component can be connected to automatically
One IP address of handset allocation of equipment end, the connection for follow-up multiple mobile phones provide differentiation foundation.
For hijacking data component, in order that accession page must can be directed to by any network address of browser access
The downloading data extraction APP page is, it is necessary to which DNS can be accessed to hijacking data component data and HTTP accesses data and reset
To therefore, DNS can be accessed data redirection and give DNS service component by hijacking data component, and HTTP access data redirection is arrived
HTTP service component；The method of redirection is that the DNS request kidnapped is redirected into default first port (such as equipment end
The ports of UDP 53), the HTTP request that equipment end is received is redirected to default second port (80 ports of such as equipment end).
For DNS service component, the first port at the component audiomonitor end, when receiving a DNS request message,
It is parsed, obtains the network address of request, DNS response messages are then constructed, for the network address arbitrarily asked, all returning equipment
The IP address at end.
For HTTP service component, the second port at the component audiomonitor end, when receiving a HTTP request, solve
Analyse the header information of the HTTP request, obtain the URL of request, then judge the URL whether be data extraction APP URL, if
Then returned data extraction APP softwares, if the otherwise returned data extraction APP download page.
For data extraction service component, the component monitors the port specified, and service data extraction APP is accessed at any time；Carry
For tactful configuration service, it is allowed to which user changes data extraction strategy by U/I interface；There is provided policy download service, it is allowed to which data carry
APP is taken to obtain data extraction strategy by api interface；Data reception service is provided, receives the data letter of data extraction APP push
Breath；A set of data protocol is defined, multiple data extraction APP data message can be received simultaneously, realize that multichannel data extracts
Function, and can simultaneously compatible wired USB mobile phone or mobile memory medium all the way data extraction.
APP is extracted for data, after the component starts, mobile phone terminal IP is sent to data extraction service component so that number
Multiple mobile phones can be distinguished according to extraction serviced component；The data difference for needing to obtain for different operative scenarios, therefore data
Extraction APP needs actively to obtain data extraction strategy to data extraction service component after starting；After obtaining data extraction strategy, number
According to extraction APP according to the tactful data progressively extracted on mobile phone, then the data-pushing of extraction is given to data extraction service component；
After data extraction terminates, prompt user to delete data extraction APP and cancel Wi-Fi connection.
Pass through the realization of said modules, you can extracted in the data of same time compatibility USB and Wi-Fi wireless multi-path,
And the data extraction between each mobile phone is unaffected mutually.
Wherein, it is as follows for the flow of Wi-Fi wireless multi-paths data extraction：
1) more target mobile phones connect the wireless routing device assembly of equipment end erection simultaneously；
2) target mobile phones operation browser, accesses any network address；
3) browser performs dns resolution, and parsing accesses the IP address of network address；
4) hijacking data component gives dns resolution data forwarding to DNS service component；
5) IP address for accessing network address is arranged to equipment end IP and returns result to browser by DNS service component；
6) browser sends the HTTP request access target page；
7) HTTP request is transmitted to HTTP service component by hijacking data component；
8) HTTP service component is returned to one and downloads the page to browser, and the page includes data extraction APP；
9) downloading data extraction APP is clicked on, APP is installed and activated after the completion of download；
10) after APP starts, the extraction of related data is carried out, and send data to data extraction service component；
11) data extraction service component receives data and performs data parsing；
12) user's uninstall is prompted after the completion of data extraction APP data-pushings；
13) unload data extraction APP and cancel wireless connection.
It is as follows for the flow of USB cable datas extraction：
1) mobile phone or move media are connected by USB line with equipment；
2) data extraction service component is communicated by USB line with mobile phone or mobile memory medium；
3) data extraction service component initiates data retrieval request；
4) mobile phone or mobile memory medium return to corresponding data and give data extraction service component；
5) data extraction service component log-on data parses；
6) USB is disconnected, and data extraction terminates.
In summary, a kind of multichannel data extracting method and its system, data extraction device and target provided by the invention
Wireless connection is carried out by Wi-Fi modes between mobile phone, the mode with wired connection is compared, more convenient, and is had preferably easily
With property, also avoid data extraction device from carrying out the caused electric quantity consumption that charges to target mobile phones, set so as to improve data extraction
Standby endurance；The IP address of itself is sent to target mobile phones by data extraction device by kidnapping DNS request, is then received
The HTTP request of target mobile phones, makes target mobile phones download installation data extraction application program, and application program is extracted certainly by data
It is dynamic to carry out data extraction so that data extraction personnel need not understand the opening ways of target mobile phones debugging mode, reduce logarithm
According to the requirement of extraction personnel；Extracted by the cable datas of USB all the way of compatibility, can be while wireless abstraction data, to it
His mobile terminal or move media carry out data extraction, add compatibility, while substantially increase the efficiency of data extraction, subtract
The stand-by period of multiple target mobile phones is lacked.The present invention can carry out data extraction to multiple target mobile phones simultaneously, substantially increase
Data extraction efficiency, and disguised strong, good portability.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
The equivalents that bright specification and accompanying drawing content are made, or the technical field of correlation is directly or indirectly used in, similarly include
In the scope of patent protection of the present invention.
