First embodiment
Referring to Fig. 2, be a kind of method for synchronizing time applied to above-mentioned server 100 provided in an embodiment of the present invention, Below in conjunction with Fig. 2 to its institute comprising the step of illustrate.
Step S101：Receive the handshake request that client is sent.
When user initiates web access requests, shaking hands for receiving web access requests described in client end response and send please Ask.
Wherein, asked during WebSocket lines are realized, it is necessary to send WebSocket lines by browser, so Server sends response afterwards, this process commonly referred to as " is shaken hands ".Wherein, WebSocket agreements are the 5th generation significant revisions A kind of agreement of HyperText Markup Language (HyperText Markup Language, HTML), it realizes browser and clothes Business device full-duplex communication.
Wherein, at least one application program (Application, APP) is installed in the present embodiment, in client, it is such as clear Device of looking at is corresponding with server, so that server provides service to the user.Wherein, the client may be, but not limited to, a People's computer (Personal computer, PC), smart mobile phone, tablet computer, mobile internet surfing equipment (Mobile Internet Device, MID) etc. electronic equipment.
Step S102：Successful feedback information is shaken hands to the client based on handshake request feedback characterization.
After server receives the handshake request of client transmission, shaken hands success for characterization based on handshake request feedback Feedback information give the client.Further, server is based on the handshake request, is established with the client WebSocket is communicated to connect, and is communicated to connect based on the WebSocket to the client feedback and is used to characterize and the client Hold successful feedback information of shaking hands.
Step S103：Receive the first time that the client is sent based on the feedback information.
Client is when receiving the feedback information of server feedback, the current time (the of system where obtaining client One time) server is sent to, the first time sent so as to the server reception client based on the feedback information.
Step S104：Local zone time is updated based on the first time.
Server updates local zone time at the first time when acquiring the first time of client transmission based on this, will The operating system of the first time write service device.
Second embodiment
Referring to Fig. 3, be a kind of method for synchronizing time applied to above-mentioned server 100 provided in an embodiment of the present invention, Below in conjunction with Fig. 3 to its institute comprising the step of illustrate.
Step S201：Receive the handshake request that client is sent.
The step is identical with step S101, referring specifically to the description to step S101.
Step S202：Successful feedback information is shaken hands to the client based on handshake request feedback characterization.
The step is identical with step S102, referring specifically to the description to step S102.
Step S203：Receive the first time that the client is sent based on the feedback information.
The step is identical with step S103, referring specifically to the description to step S103.
Step S204：Local zone time is updated based on the first time.
The step is identical with step S104, referring specifically to the description to step S104.
Step S205：Judge whether WebSocket communication connections are kept.
Judge WebSocket communication connection whether be kept, WebSocket communication be kept when, namely client and When server keeps WebSocket communication connections, then step S206 is performed, conversely, namely between client and server During WebSocket communication disruptions, WebSocket communication connections are deleted, to re-establish connection next time, namely next time is based on The handshake request that client is sent, WebSocket communication connections are established with client.
Step S206：Receive the second time that the client is sent.
When WebSocket communications are kept, namely during client and server holding WebSocket communication connections, connect Receive the second time that the client is sent.Further, can receive the client by pre- as a kind of embodiment If the second time that the cycle actively sends.For example, every one minute client just to server send be currently located system when Between (the second time).Obtain and ask to client sending time as another embodiment or server, client Request the second time of feedback is obtained based on the time, so that server receives the second time of the client transmission.
, wherein it is desired to explanation, the setting of the predetermined period should be set according to being actually needed, it is impossible to be shown above-mentioned Understanding Time into being limitation of the present invention.
Step S207：Local zone time is updated based on second time.
When receiving the second time of client transmission, local zone time is updated based on second time.Further, exist Receive client transmission the second time when, judge second time with local current time it is whether consistent, for it is no when, base Local zone time is updated in second time.
In addition, as a kind of embodiment, WebSocket is kept to lead to when inconsistent, namely in client and server During letter connection, after updating local zone time based on second time, this method also repeats above-mentioned steps S205, step The step of rapid S206 and step S207, stop when from the time that client receives and completely the same local zone time, keep away Exempt from cumulative errors.
3rd embodiment
The embodiment of the present invention additionally provides a kind of time synchronism apparatus 110, as shown in Figure 4.The time synchronism apparatus 110 wraps Include：First receiving module 111, feedback module 112, the second receiving module 113, the first update module 114, judgment module 115, Three receiving modules 116 and the second update module 117.
