When the message or data from client application are received by the second session, server is searched and the second meeting according to gap marker
First session identification of words mark association, the message or data is sent to by the first session the browser of computing device.By
Transit server, therefore referred to as indirectly connected communication pattern are transferred through in this.The invention also provides one kind is without server
The data-transmission mode of transfer, i.e., direct-connected communication pattern.Under direct-connected pattern, the browser of computing device and the visitor of mobile terminal
Data transfer between the application of family end can be carried out by being directly connected between them, without transit server, so that
Improve transmission speed and flow and expense may be saved.Direct-connected communication pattern explained below sets up process.
First, the passage that the client application of mobile terminal has been set up by server, i.e. the first session and the second session,
The direct-connected communication invitation message for including the direct-connected mailing address of mobile terminal is sent to the browser of computing device.The example lattice of message
Formula is as follows：
Wherein 192.168.1.119 is the direct-connected mailing address of mobile terminal oneself, the inside IP of such as WLAN
Address.Authentication information can also be used as in direct-connected communication notifications message comprising the numerical value (id) generated at random.Browse
Device request after direct-connected communication invitation message is received accesses the direct-connected address included in message.This access is similar to ping behaviour
Make, i.e., browser sends packet to the direct-connected mailing address, if other side receives the packet, can return to an equal amount of number
According to bag, thereby confirm that connection between the two is unimpeded, otherwise mean that browser can not access direct-connected mailing address, both
Continue to operate under indirectly connected pattern.When the client application of mobile terminal receives the access request message from browser
When, determine that mobile terminal and computing device can be carried out direct-connected.Can in security, the access request message of browser in order to strengthen
So that comprising the numerical value in direct-connected communication notifications message, client application can be verified to the numerical value.If checking is consistent, move
The client application of dynamic terminal sends direct-connected communication response message by server to browser, and format sample is
{
type:"directOK"
}
Client application enters direct-connected pattern, starts web server.Browser is receiving direct-connected communication response message
Afterwards, also into direct-connected pattern.So, between client application and the browser of computing device in the way of server-client
Carry out data transmission.In addition, after the access request message from browser is received, client application can record source IP
Address and write-in cookie, browser, which downloads the request of file, for after will verify IP address and cookie, if not
With then returning to 403 mistakes.Further, due to the client application not same area of server and mobile terminal, and browser and client
Using access request can be sent using AJAX (asynchronous JavaScript and XML) modes, and in view of the same of browser
The limitation of source policy, therefore, the client application of mobile terminal can also realize that cross-domain resource shares (CORS), and it can be direct-connected
Being added in the response header of invitation message allows the information (Access-Control-Allow- of the cross-domain access of browser
Origin), so that cross-domain access can be carried out when browser receives the direct-connected invitation message.
Under direct-connected communication pattern, signaling/message can also be switched to shifting from former passage (i.e. by the passage of server)
It is dynamic to be directly connected to passage between terminal and computing device browser, so as to realize the localization of message.The correlation of switching channel
Message format sample it is as follows：
The directChannel message is sent to the browser of computing device by mobile terminal by server, is informed straight
Connect the address (url) of communication port.Browser is polled (polling) to url addresses upon receiving the message.It is mobile whole
End can start direct communication channel after the GET request of poll is received, and stop toward former passage POST message.Mobile terminal to
Browser send switchChannel message, format sample for
"type":"switchChannel"
}
SwitchChannel message informing browser switching channels.Browser is received after the message, is stopped to server
Former passage POST message.
Once into direct-connected pattern, directly enterprise can be for example passed through without high in the clouds between browser and mobile terminal
Internal local network transport data.So, the flow of mobile terminal is not only saved, and substantially increases the speed of data transfer
Degree, also improves the Consumer's Experience by browser administration mobile terminal data.
The document transmission process under direct-connected communication pattern and indirectly connected communication pattern will be described respectively below.
Under direct-connected communication pattern, browser is operated in response to user, the file in acquisition request mobile terminal.For example,
User views the information such as the listed files stored on mobile terminal, thumbnail on a web browser, is inputted by mouse, keyboard etc.
Equipment specifies the file to be obtained.Browser sends in file request message (requestFile), the message to mobile terminal and wrapped
Mark containing requested document.Mobile terminal returns to the logical of the web addresses comprising this document after file request is received
Know message.The web addresses of this document indicate absolute url of this document in the web server of mobile terminal.Browser is being received
To after response message, file is downloaded from mobile terminal according to web client-server mode.
In direct-connected communication pattern, it is understood that there may be some special implementations.For example, PDF.js may be obtained by AJAX
Pdf document is taken, therefore, the problem of having cross-domain under direct-connected communication pattern.At this moment the web server of mobile terminal is needed to realize
CORS (across source Resource Sharing Protocol).The setting and confirmation of some heads (Headers) that CORS passes through web server is realized
Cross-domain request, is not detailed herein.
Under indirectly connected communication pattern, browser is operated in response to user, the file in acquisition request mobile terminal.Browse
Device is sent in file request message (requestFile), the message by server to mobile terminal includes requested document
Mark.Mobile terminal uploads onto the server this document after file request is received.Server is returned to browser and wrapped
The notification message of web addresses containing this document.The web addresses of this document indicate this document in the web server of server
Address.Browser downloads file according to web client-server mode after response message is received from server.
Except answering browse request, mobile terminal can also actively send the file to browser.For example, user can be
Photo is sent to browser in the client application of mobile terminal.Under direct-connected pattern, browser sends text to mobile terminal
Part sends message (sendFile).The message format example is
Mobile terminal sends the notification message of the web addresses comprising this document to browser.The web addresses of this document are indicated
Absolute url of this document in the web server of mobile terminal.Browser is after response message is received, according to web client
End-server mode downloads file from mobile terminal.In indirectly connected communication pattern, browser sends file to mobile terminal and sent out
Message is sent, the file that mobile terminal will be sent is uploaded onto the server, server receives the web addresses that this document is included after file
Notification message be sent to browser, browser is after response message is received, according to web client-server mode from clothes
Business device downloads file.
It should be noted that transmission file here can be two-way, it can both send, also might be used from mobile terminal to browser
To be sent from browser to mobile terminal.
So, file transmission easily can be carried out with mobile terminal by the browser of computing device, without in meter
Calculate and software is installed in advance in equipment.
According to one embodiment of present invention, it is proposed that according to above-mentioned file transmission principle in mobile terminal and computing device
