Android Question Http Server with HttpJob is not sync?

[susu]

Hi,

Base on Erel's example of Http Server, I wrote this code to get public IP and export to webpage:

Sub Server_HandleRequest (Request As ServletRequest, Response As ServletResponse)   
    Try
        Select True
            Case Request.RequestURI = "/"
                Dim Job As HttpJob
                Job.Initialize("Job1", Me)
                Job.Download("http://api.ipify.org/")               
                HandleMainPage (Response)
            Case Else
                SetContentType(Request.RequestURI, Response)
                Response.SendFile(File.DirAssets, DecodePath(Request.RequestURI.SubString(1)))
        End Select
    Catch
        Response.Status = 500
        Response.SendString("Error serving request: " & LastException)
    End Try
End Sub

Sub JobDone (Job As HttpJob)
    If Job.Success Then
        Select Job.JobName
            Case "Job1"
                PrintYourIP(Job.GetString)
                count = count + 1
                Log("Count " &count)
                Log(Job.GetString)
        End Select
    Else  'Failed
        Select Job.JobName
            Case "Job1"
                Log("Failed to get IP")
        End Select
    End If
    Job.Release
End Sub

Sub PrintYourIP(s As String)
    YourIP = " Hey, Your IP is "&s
End Sub

Sub HandleMainPage (Response As ServletResponse)
    Dim MainPage As String = GetTemplate("main_template.html") 'load the template from the assets folder
    MainPage = MainPage.Replace("$TIME$", DateTime.Time(DateTime.Now))
    Dim information As StringBuilder
    information.Initialize
    information.Append(count).Append(YourIP).Append("<br/>")
    MainPage = MainPage.Replace("$OTHERINFORMATION$", information)
    MainPage = MainPage.Replace("$GREETING$", greeting)
    Response.SetContentType("text/html")
    Response.SendString(MainPage)
End Sub

In Logcat I see it work correctly:
Count 1
27.3.2XX.XXX
But in webpage it not show anything until I refresh it. Then in Logcat it likes:
Count 2
27.3.2XX.XXX
and in webpage it shows: 1 Hey, Your IP is 27.3.2XX.XXX
How can I make the webpage always show right value? Thank you.

Ps: Please find attachment for sample code.

sure it is sync. But you need to answer in the Server_HandleRequest event directly.
But you are leaving the sub to do a download (in this case to get the ip).

You can use a time for ex. in the server to check the ip every x minutes and then store the answer so you can use the stored value in the Server_HandleRequest event and send it directly in the response object.

Thanks Don. How can I handle Server Request after HttpJob finish?

 

[DonManfred]

i dont know if you can at all. At least not with 6.8

The next version should be able to pause the sub, do the download and then resume the sub.
If this will work in the server response event i dont know

i would try to put the response object into the Jobs Tag for the downloadjob.
In jobdone you can try to use the response object from the Tag to send a answer. To try to

But i´m not sure if it will work or not. Never used the server....
