Step timestamp is assigned to data renewal time stamp.In this embodiment, the value of Refresh Data timestamp is updated to
1481432061220, the data renewal time value of stamp is updated to 1481432061008.It is obvious that mobile terminal 300 is obtaining
To after homepage data, it can be handled to show corresponding page in screen.Since the data generally got are Json
The data of format will carry out dissection process to the data first to judge whether the request returned is correct.Specifically, according to Json
Returncode field in the data of format is judged, if returncode is 0, illustrates that the data returned are correct,
The data in result field are parsed, if returncode is not 0, carry out corresponding mistake according to the value of returncode
Processing.Further, if returncode is -666, illustrate that user right sends variation, first obtain new user right
Then list judges whether also there is the permission for obtaining synchrodata, if there is then obtaining data again, if prompting without if
To user temporarily without the permission for synchronizing the data, while the local data deletion before in mobile terminal 300 no longer being shown.If
Returncode is -200, then illustrates user's different-place login, then jump back out to login interface.If returncode is -1, table
Bright this time request is there are mistake, and mobile terminal 300 is parsed without Json data, the close friend that straight-forward network server 500 returns
Error message is prompted to user.An example of homepage data is shown below, specific as follows:
{"returncode":0,
" message ": " success ",
"result":{"rowcount":0,"pagecount":0,"pageindex":0,"lastupdatetime":
