Step S607：Judgement retries whether operation succeeds, if so, then performing step S609, otherwise, performs step S608.
Step S608：Service end returns to the prompting message of connection failure to client.
Step S609：The connection request of data-pushing manager processes client, and by the connection ID of client and user
Information is saved in storage system.
Specifically, after data-pushing manager receives the connection request of client, first by push server (Push
Server) handled, Push Server can obtain the client connection number of each push client (Push Client)
Summation, find client by comparing and connect a minimum Push Client of number, thus Push Client are responsible for and client
Editor's connection is established at end, can so ensure the client load equilibrium connected on each Push Client.Then, Push
The connection ID of this Push Client and client, user profile etc. are sent to corresponding form service by Server, and by form
The connection ID, user profile are added to user's group by service, and are preserved to storage system (such as Redis), finally by connection ID, use
The link informations such as family information return to client, so that client is according to link information establishment and Push Client connection.
User's group also includes editor's link information (including connection ID and user profile) of other users in the group, and this
For a little users when establishing editor's connection respectively with service end, these information also can be saved in storage system by form service respectively,
When there is user to exit Table edit function, the user edits connection and will be closed accordingly, editor's link information of the user
Also the user's group can be moved out of simultaneously.
Step S610：Client-side editing data form, and when reaching the condition of data modification pushing condition concentration, will compile
The data collected are submitted to the corresponding form service of service end.
The condition that data modification pushing condition is concentrated is that client user is set in advance according to demand, is specifically included as follows
Condition：Data are changed more than 3 characters, and modification time was more than 3 seconds.
Step S611：The form Service Notification data-pushing manager of service end performs data-pushing.
Step S612：Every other user of the data-pushing manager into user's group in addition to the client pushes number
According to.
Step S613：Service end judges whether data-pushing succeeds, if so, then performing step S614, otherwise, performs step
S615。
Step S614：The other users for receiving data carry out data renewal according to the data of the push.
Step S615：Data-pushing manager retries data-pushing, if retrying failure, push failure is returned to client
Prompting message.
If retrying failure, client can pass through after the prompting message of push failure of service end return is received
Line send a notice other users renewal form in data.
When client exits Table edit function, data-pushing manager will close Push Client and the client
Editor's connection, and form service removes the connection ID of the client, user profile from user's group.
