Android Question ResponseError. Reason: Internal Server Error, Response: Using OkHttpUtils2 Library

[Walter Scafati]

Hi, I using the OkHttpUtils2 library per to communicate with my server via JSON message.
Sometimes I have the error "ResponseError. Reason: Internal Server Error, Response:" and I can'receive the data.

Like the post: https://www.b4x.com/android/forum/t...ad-of-a-file-fails-httputils2-succeeds.87041/
I removed the OkHttpUtils2 library and I added the two source code file of this (HttpJob.bas and HttpUtils2Service.bas) but I have the error:

B4A Versione: 7.80
Analisi del Codice. Error
Errore Analisi Programma.
Descrizione errore: Tipo sconosciuto: okhttprequest
Manca un riferimento ad una libreria?
Errore nella linea: 11 (HttpJob)
Private req As OkHttpRequest

The row 11 is:

Private req As OkHttpRequest

Must add I some library?

 

[Erel]

OkHttp

 

[Walter Scafati]

After the add of OkHttp I have this error:

B4A Versione: 7.80
Analisi del Codice. Error
Riferimento a un oggetto non impostato su un'istanza di oggetto.

From the other post:

You need to remove OkHttpUtils2 library and replace it with the two code modules. Make HttpUtils2Service.hc a public variable.

I don't understand this step, where I must to declare the HttpUtils2Service.hc? what Type of variable for the declaration?

Public HttpUtils2Service.hc as ?

 

[Erel]

The two modules are available here: [B4X] OkHttpUtils2 / iHttpUtils2 / HttpUtils2 source code

 

[Walter Scafati]

Yes but I have the error message after I included the two files.

 

[Erel]

Can you upload the project?

 

[Walter Scafati]

I tried but "The uploaded file is too large". The size is about 3MByte

 

[Erel]

Make sure to use File - Export as zip.

 

[Walter Scafati]

No, I did not know that for the zip file must to use the "Export as zip" from b4a, I did use the winzip software. Sorry is the first time that I make the upload of one project.
Now I do it from b4a but is the same, my zip project is 587 KBytes, but the message teels me:

The following error occurred
The uploaded file is too large.

 

[Erel]

You can send the zip to erel@basic4ppc.com.

 

[Walter Scafati]

Just sent! Thanks!

AppUdating library references OkHttpUtils2.
1. Close the IDE.
2. Edit AppUpdating.xml and remove this line:
<dependsOn includesSingletonModules="true">okhttputils2</dependsOn>

 

[Walter Scafati]

Now the error is disappeared, but after the compilation and the installation on the device, the App exit at the moment of check new version via AppUpdating function.

 

[Erel]

I think that AppUpdating source code is available. Try to use the source code instead of the library.

 

[Walter Scafati]

Yes, because now the other applications that using the AppUpdating Library not working more.

 

[Erel]

Yes, because now the other applications that using the AppUpdating Library not working more.

This can be solved easily. Add a reference to OkHttpUtils2 library in these projects.

You can also compile your own version of OkHttpUtils2. Make sure to update it in the internal libraries folder.

 

[Walter Scafati]

Hi Erel, I choose this way:

You can also compile your own version of OkHttpUtils2. Make sure to update it in the internal libraries folder.

I compiled my OkHttpUtils2My using the two files (HttpJob.bas and HttpUtils2Service.bas) and I added in the main of library project this part of code for the cookie deleting

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.

End Sub

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.

End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    'Activity.LoadLayout("Layout1")

End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

If HttpUtils2Service.hc.IsInitialized Then
       Dim jo As JavaObject = HttpUtils2Service.hc
       jo = jo.GetFieldJO("client").RunMethod("cookieJar", Null)
       Dim r As Reflector
       r.Target = jo
       Dim CookieManager As JavaObject = r.GetField("cookieHandler")
       CookieManager.RunMethodJO("getCookieStore", Null).RunMethod("removeAll", Null)
End If

but I have always the same error "ResponseError. Reason: Internal Server Error, Response:" on one of the queries.

 

[Erel]

Why do you think that this error is related to the cookies?

 

[Walter Scafati]

Good question!
Because I found the same problem in this post: https://www.b4x.com/android/forum/t...ad-of-a-file-fails-httputils2-succeeds.87041/
and your solution was to clean the cookie

 

[Erel]

This was an issue very specific to the site he communicated with.
