Part, user terminal can be issued local connection related information based on the feature card.
Specifically, can use but be not limited to following two mode:
First way are as follows: the first user terminal obtains local location information, generates corresponding mark for this connection
Know information, and based on local location information and the identification information generated for this connection, calls received Webpage
Generate corresponding two dimensional code.And the two dimensional code of generation is issued by the Webpage.
The location information of first user terminal can there are many, e.g., if the first user terminal and second user terminal are same
(internet e.g., is connected to by same wireless router) in one local area network, then the location information that the first user terminal uses
For the lan address of itself；If the first user terminal and second user terminal not in same local area network, (e.g., by GPRS,
3G or 4G are connected to internet), then the location information of the first user terminal is the public network address of itself.
On the other hand, the first user terminal can generate an identification information, the mark after receiving above-mentioned Webpage

The second way are as follows: the first user terminal obtains local location information, generates corresponding mark for this connection
Know information, and calls received Webpage to generate a random number, and issue random number by the Webpage, with
And local location information and the identification information generated for this connection are pushed into central server, wherein the random number
Identification information for obtaining the location information of the first user terminal in central server and being generated for this connection.
Similarly, the location information of the first user terminal can there are many, e.g., if the first user terminal and second user terminal
(internet e.g., is connected to by same wireless router) in same local area network, then the position that the first user terminal uses
Information is the lan address of itself；If the first user terminal and second user terminal (e.g., pass through not in same local area network
GPRS, 3G or 4G are connected to internet), then the location information of the first user terminal is the public network address of itself.
On the other hand, the first user terminal can generate an identification information, the mark after receiving above-mentioned Webpage
Information is for this connection of unique identification.
Then, the first user terminal can pass through Webpage and (e.g., " the new connection of foundation " printed words in the webpage clicking page
Function button) generate a random number, and the random number is issued by Webpage, and by the location information of local
Central server is pushed to the identification information of this connection.
At this point, second user terminal can connect to the central server, inputs the first user terminal and issued by screen
Random number, central server will by the location information of the first user terminal and this connection identification information be sent to second
User terminal, second user terminal can location information based on acquisition and identification information send and connect to the first user terminal
Establish request.
The second way is more suitable the user terminal that can not be scanned the two-dimensional code.Although the first user terminal is by local position
Information and the identification information of this connection are sent to central server, but central server is only protected as a pair of of key value
Deposit, and after being supplied to second user terminal voluntarily delete or when second user terminal does not obtain in data validity interval
It voluntarily deletes, therefore, the leakage of user data will not be caused, safety can also obtain effective guarantee.
Step 120: the first user terminal receives the company that second user terminal is sent based on the connection related information of acquisition
Foundation request is connect, establishes connection between the second browser that the first browser locally used and second user terminal use,
And it is connected between local and second user terminal and is carried out data transmission using this.
When request is established in the connection that first user terminal receives the transmission of second user terminal, it can be established by the connection
Request obtains the connection related information of second user terminal, in this way, can use in the first browser locally used and second
Connection is established between the second browser that family terminal uses, to complete Point-to-Point Data Transmission.Specifically, the first user terminal
And second user terminal can establish P2P computing between the first browser and the second browser based on Javascript agreement
(Peer to Peer, P2P) connection, to complete point-to-point transmission.
Using the above scheme, it when realizing the Point-to-Point Data Transmission between user terminal, avoids material upload to cloud sky
Between, to effectively reduce the risk that data leaks, and user without installing specific software, Yi Jiye on the subscriber terminal
Without registering particular account, it is only necessary to the point pair between user terminal can be thus achieved using the browser embedded on user terminal
Point transmission, this greatly reduces realization and operation complexity, also more convenient and efficient.
After data end of transmission, user's each self closing on the first user terminal and second user terminal locally use
One browser and the second browser can both terminate current point-to-point transmission process, without executing operation bidirectional, even if user forgets
Note closes browser, and more than after validity period, point-to-point transmission process ends automatically Webpage, if wanting to continue to transmit data,
Need to re-establish new connection.
