Embodiment
In order to reduce the operation complexity of Point-to-Point Data Transmission, in the embodiment of the present invention, between two user terminals, set up session connection by the Web browser on user terminal, thus realize the Point-to-Point Data Transmission between user terminal.
Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is described in detail.
In the embodiment of the present application, the system architecture of first user terminal, the second user terminal and central server as shown in Figure 1A, based on this system architecture, consult shown in Figure 1B, in the embodiment of the present invention, when carrying out Point-to-Point Data Transmission between the ues, it is as follows that first user terminal performs flow process:
Step 100: first user terminal is connected to the central server of specifying by the first browser according to user instruction.
In the embodiment of the present invention, first user terminal receives user instruction, carry the chained address of the central server of specifying in this user instruction, first user terminal, based on this chained address, is connected to above-mentioned central server of specifying by first browser of this locality.
Step 110: the Webpage that first user terminal receiving center server returns, and issue based on the connection related information of this Webpage by this locality.
In the embodiment of the present invention, can be provided with certain specific feature card in the Webpage that central server returns, user terminal can be issued based on the connection related information of this feature card by this locality.
Concrete, can adopt but be not limited to following two kinds of modes:
First kind of way is: first user terminal obtains local positional information, connect for this and generate corresponding identification information, and being connected based on the positional information of this locality the identification information generated with for this, the Webpage calling reception generates corresponding Quick Response Code.And issued by the Quick Response Code of this Webpage by generation.
The positional information of first user terminal can have multiple, as, if first user terminal and the second user terminal (e.g., are all connected to the Internet by same wireless router) in same local area network (LAN), then the positional information that first user terminal uses is the lan address of self; If first user terminal and the second user terminal be not in same local area network (LAN), (e.g., being connected to the Internet by GPRS, 3G or 4G), then the positional information of first user terminal is the public network address of self.
On the other hand, first user terminal, after receiving above-mentioned Webpage, can generate an identification information, and this identification information is used for unique identification, and this connects.
Then, first user terminal can pass through Webpage (e.g., the function button of " generation Quick Response Code " printed words in the webpage clicking page), and the identification information that the positional information based on this locality is connected with this generates a Quick Response Code.
Now, second user terminal can be scanned the Quick Response Code that first user terminal screen is issued by camera, thus the identification information that the positional information obtaining first user terminal is connected with this, and send connection establishment request based on the positional information obtained and identification information to first user terminal.
First kind of way is applicable to the user terminal that can scan Quick Response Code.When adopting first kind of way, any data of end side all do not transfer to network side, and user terminal only needs to obtain specific Webpage can realize point-to-point transmission, and Information Security obtains effective guarantee.
The second way is: first user terminal obtains local positional information, connect for this and generate corresponding identification information, and the Webpage calling reception generates a random number, and by this Webpage, random number is issued, and the identification information positional information of this locality being connected generation with for this pushes to central server, wherein, this random number is used for being connected in the positional information of central server acquisition first user terminal the identification information generated with for this.
In like manner, the positional information of first user terminal can have multiple, e.g., if first user terminal and the second user terminal in same local area network (LAN) (as, all be connected to the Internet by same wireless router), then the positional information that first user terminal uses is the lan address of self; If first user terminal and the second user terminal be not in same local area network (LAN), (e.g., being connected to the Internet by GPRS, 3G or 4G), then the positional information of first user terminal is the public network address of self.
On the other hand, first user terminal, after receiving above-mentioned Webpage, can generate an identification information, and this identification information is used for unique identification, and this connects.
Then, first user terminal can by Webpage and (as, " set up and newly connect " function button of printed words in the webpage clicking page) generate a random number, and this random number issued by Webpage, and the identification information that the positional information of this locality is connected with this is pushed to central server.
Now, second user terminal can be connected to this central server, the random number that input first user terminal is issued by screen, the identification information that the positional information of first user terminal is connected with this just can be sent to the second user terminal by central server, and the second user terminal just can send connection establishment request based on the positional information obtained and identification information to first user terminal.
The second way is applicable to the user terminal that cannot scan Quick Response Code more.Although the identification information that local position information is connected with this is sent to central server by first user terminal, but central server only it can be used as a pair key value to preserve, and delete voluntarily after being supplied to the second user terminal or delete voluntarily when the second user terminal does not obtain in data validity interval, therefore, also can not cause the leakage of user data, fail safe can also obtain effective guarantee.
Step 120: first user terminal receives the connection establishment request that the second user terminal sends based on the connection related information obtained, connect between the second browser that the first browser used in this locality and the second user terminal use, and adopt this to be connected between this locality and the second user terminal to carry out transfer of data.
When first user terminal receives the connection establishment request of the second user terminal transmission, the connection related information of the second user terminal can be obtained by this connection establishment request, like this, connect between the second browser that first browser that just can use in this locality and the second user terminal use, thus complete Point-to-Point Data Transmission.Concrete, first user terminal and the second user terminal can be set up P2P computing (PeertoPeer, P2P) based on Javascript agreement and connect between the first browser and the second browser, thus complete point-to-point transmission.
Adopt such scheme, when realizing the Point-to-Point Data Transmission between user terminal, avoid material upload to cloud space, thus the risk that the data that effectively reduces leaks, and user is without the need to installing specific software on the subscriber terminal, and also without the need to registering particular account, only need to use embedded browser on user terminal namely can realize the point-to-point transmission between user terminal, this greatly reduces realization and operation complexity, also more convenient and swift.
After transfer of data, user's the first browser that each self closing this locality uses in first user terminal and the second user terminal and the second browser both can terminate current point-to-point transmission flow process, without the need to performing operation bidirectional, even if user forgets closedown browser, after Webpage exceedes the term of validity, point-to-point transmission flow process terminates automatically, continues transmission data, then need to re-establish new connection if want.
Under prior art, Bluetooth technology also can realize point-to-point transmission, but some equipment acquiescence is not with blue-tooth device, e.g., and desktop computer and part notebook computer, the therefore technology that provides not as good as the embodiment of the present invention of the range of application of Bluetooth technology.On the other hand, typical bluetooth transmission speed is at 1-3Mb/s, and the technology using the embodiment of the present invention to provide, if two user terminals are in same local area network (LAN), transmission rate can reach local area network (LAN) extreme value in theory, usually can reach 72Mb/s ~ 150Mb/s, exceedes bluetooth more than 50 times.Further, Bluetooth transmission distance is very short, within 10M, and the technology adopting the embodiment of the present invention to provide, for WLAN (wireless local area network), transmission range equals the range of signal of wireless network, a usual router when there is no directional antenna range of signal at about 100M.Further, bluetooth does not send outer net request, so the bluetooth applications that cannot upgrade in time.And the technology adopting the embodiment of the present invention to provide, the Webpage that can center server be used at any time up-to-date, thus make user terminal can use up-to-date function.
Consult shown in Fig. 2, in the embodiment of the present invention, when carrying out Point-to-Point Data Transmission between the ues, it is as follows that the second user terminal performs flow process:
Step 200: the second user terminal receives the connection related information of the first user terminal that first user terminal is issued based on Webpage, and this Webpage obtains after first user terminal is connected to the central server of specifying.
The concrete obtain manner of Webpage, see step 100, does not repeat them here.
When performing step 200, the second user terminal can adopt but be not limited to following two kinds of modes:
First kind of way is: the second user terminal receives the Quick Response Code that first user terminal is issued based on above-mentioned Webpage, this Quick Response Code be the positional information of first user terminal based on first user terminal be connected with for this generate corresponding identification information, call above-mentioned Webpage generate;
The second way is: the second user terminal receives the random number that first user terminal is issued based on above-mentioned Webpage, and the positional information adopting this random number to obtain from central server the first user terminal that first user terminal is uploaded is connected the identification information generated with for this.
Step 210: the second user terminal sends connection establishment request based on the connection related information obtained to first user terminal, and connect between the first browser of using of the second browser used in this locality according to the response of first user terminal and the first family terminal, and be connected between this locality and first user terminal carry out transfer of data based on this.
