Android Question Expectation Failed

[Fabio Campanella]

Hi,
when I use the Httpjob with basic autentication and json data i receive the 417 Error to the server (Expectation Failed)

I find this solution but I don't know when I pass this in Jttpjob class

Can you help me?

request.getParams().setBooleanParameter( "http.protocol.expect-continue", false )

 

[Erel]

This doesn't look relevant. Are you using OkHttpUtils2?

 

[Fabio Campanella]

No, I use Http and httputils2 because i don't able to write the following code with same behaviour:

private Sub CallWS(callMode As Int, WSName As String, Firmed As Boolean, JSONData As String)
  
   LastCallType = callMode
  
   Dim j As HttpJob
   j.Initialize(WSName, Me)  
   Dim BC As ByteConverter
   Dim Data() As Byte = BC.StringToBytes(JSONData, "utf-8")
   If callMode = CALL_MODE_POST Then
     'j.PostString(EndPoint & WSName, JSONData)
     j.PostBytes(EndPoint & WSName, Data)    
   Else
     j.Download(EndPoint & WSName & JSONData)
   End If
  
   j.GetRequest.Timeout = 25000
   j.GetRequest.SetHeader("Content-Type", mContentType & ";charset=utf-8")
   'j.GetRequest.SetContentType(mContentType)
   'j.GetRequest.SetContentEncoding("UTF-8")
   If Firmed = True Then
     j.GetRequest.SetHeader("Authorization", "Bearer " & mFirm)    
     If callMode = CALL_MODE_POST Then
      
     End If
   End If
  
   ' Azzera le variabili impostate in precedenza
   If mVars.IsInitialized = True Then mVars.Clear
   mVars.Initialize
  
   If mList.IsInitialized = True Then mList.Clear
   mList.Initialize
  
  
  
End Sub

I'm not be able to set the header with okhttp

 

[Erel]

Try with OkHttpUtils2. You just need to set the content type with SetContentType.

 

[Fabio Campanella]

Try with OkHttpUtils2. You just need to set the content type with SetContentType.

And this how I'll set it?

j.GetRequest.SetHeader("Authorization", "Bearer " & mFirm)

 

[Erel]

Yes.

 

[Fabio Campanella]

I've Tried with okhttp but the same error was occured: Expectation failed

 

[Erel]

Is this the exact error message? Can you post the logs?

 

[Fabio Campanella]

This is the error (httpjob.errormessage)

ResponseError. Reason: Expectation Failed, Response:

This is the page where there is a explanation of the issue:

It's simila to my issue

 

[Erel]

You can call HttpClient.SetHttpParameter to try this solution (with Http / HttpUtils2). If you are using HttpUtils2 then use the source code instead of the compiled library and call it in HttpUtils2Service module.

 

[Fabio Campanella]

Ok, there are the last httputils2 code (2.50)? I have 2.01 version. Thanks!

 

[Erel]

Not sure as this is an old library. v2.01 should work properly.

 

[Fabio Campanella]

When Compile HttpUtils2Sercivice I've received this error:




src\it\digitalup\icommlab\myhttputils2service.java:247: error: cannot access ClientProtocolException
_hc.Initialize("hc");
^
class file for org.apache.http.client.ClientProtocolException not found

 

[Erel]

You will need to use an older version of android.jar to compile (Tools - Configure Paths).

 

[Fabio Campanella]

Ok, i've compiled but the expectation failed remain.

...

 

[Erel]

The error is somewhere else. Can you post a link to this server?

 

[Fabio Campanella]

the server is a customer of mine. The authentication procedure is quite complex. I prepare you a test code so you could try it

 

[Fabio Campanella]

This is the code that reply the issue:

 

[Fabio Campanella]

VERY SORRY Erel!!!
The problem was in the server. The payload json contained a variable that he did not like

I was angry with the customer for the time that made me lose! Sorry!!! is ok now without a variable. in my code that send before, leave latitude and longitude vars.

Thank for your precious support!!!!
Regards!!
