Android Question HTTPJob.PostString Auth

worksoft.marco · Nov 21, 2013

Greetings

Has anything changed in the library HttpUtils2 in version 3.00??

In the previous version, the authentication with PostString worked perfectly (following example code):

B4X:

Dim Job As HttpJob              
  
Job.Initialize("Cidades", Me)
Job.Username = usuario
Job.Password = senha
Job.PostString("http://" & endereco & "/datasnap/rest/TServerMethods1/baixaCidades", idemp)

Now, I can not authenticate to the webservice, I made a debug in the webservice and username and password are coming blank.

If you changed the way of authenticating, would like some tips accordingly.

Thanks in advance.

The authentication method hasn't changed. There were some changes in Http library however they were not supposed to affect the authentication.

worksoft.marco · Nov 22, 2013

Sorry for the insistence, but I'm out of ideas to continue.

Is there another way to debug the error, for example, debug the httputils2 routine?

Or another line of reasoning, what could affect authentication?

Thanks in advance.

Erel · Nov 24, 2013

I just tested it with a page that required basic authentication:

B4X:

Dim job1 As HttpJob
job1.Initialize("Job1", Me)
job1.Username = "xxx"
job1.Password = "xxx"
job1.PostString("http://www.b4x.com/android/vv18/print.php", "a=b")

It works fine.

I made some tests, but not working yet.

What I did:
- Updated the android development libraries;
- Reinstalled basic4android;
- Tried with other servers;

I do not know if it helps, but here is the debug when I get the unauthorized message from server:

B4X:

** Activity (sincronizacao) Create, isFirst = true **
** Activity (sincronizacao) Resume **
startService: class anywheresoftware.b4a.samples.httputils2.httputils2service
** Service (httputils2service) Create **
** Service (httputils2service) Start **
Failed to read error message.
** Activity (sincronizacao) Pause, UserClosed = true **

Would like an opinion on what else I could debug to determine the problem.

Thanks in advance.

Erel · Nov 27, 2013

Does it only fail on this page? Have you tried it with other servers?

It is strange that it failed to read the error message. See if there are any messages in the unfiltered logs.

worksoft.marco · Nov 27, 2013

Yes, I tried on other servers.

Here the unfiltered logs.

Authentication error: Unable to respond to any of these challenges: {}

Seems like the authentication method in your server has changed.

worksoft.marco · Nov 27, 2013

Erel

I turned back to version 2.71 and the authentication worked fine.

The server is written in Delphi 2010 (Datasnap + JSON) and has not changed.

Any more information I can provide to resolve this issue?

For now I'll keep using the version 2.71

Thanks in advance.

Erel · Nov 28, 2013

Not sure what has changed. This issue will be tracked.

worksoft.marco · Dec 3, 2013

Erel

I installed b4a 3.00 on a new machine to test if it could be some issue related to the upgrade.

However, the result was the same, I can not authenticate with version 3.00 on the new machine,
but with version 2.71 on the old machine, everything works perfectly.

If there is any more information I can provide, I'm available to help.

Thanks.

Erel · Dec 3, 2013

Is this server public? Can you send me the link to it?

worksoft.marco · Dec 11, 2013

No, but I will create one for testing purposes. I will send the link soon.

pgoodwin · Jan 21, 2014

I have this exact same issue, v. 2.71 works flawlessly. Anything higher and I get an unauthorized back. Using digest authentication on the server.

Erel · Jan 21, 2014

Is this a public server? If yes then I would like to test it if possible.

pgoodwin · Jan 21, 2014

Unfortunately it is not a public server.
The server logs do show differences between the 2 versions eg.

#Fields: date time s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs(User-Agent) sc-status sc-substatus sc-win32-status time-taken
B4a v 2.71
2014-01-21 13:48:43 0.0.0.0 GET /api/APICALL - 15 - 0.0.0.41 - 401 0 0 4
2014-01-21 13:48:43 0.0.0.0 GET /api/APICALL - 15 USERNAME 0.0.0.41 - 200 0 0 45

As you can see the original get request bounces back as unauthorized and B4A responds as per digest rules and the call is returned OK

B4a v. 3.20
2014-01-21 17:37:02 0.0.0.0 GET /api/APICALL - 15 - 0.0.0.41 - 401 0 0 12
2014-01-21 17:37:02 0.0.0.0 GET /api/APICALL - 15 - 0.0.0.41 - 401 1 2148074255 7

In the new versions the original unauthorized call is there, however the second call that should be passing the USERNAME credential does not have it.

*Note IPAddresses, USERNAME, APICALL and PORT have been changed to imaginary values

Erel · Jan 22, 2014

I've tried it here with a local server and it worked correctly. If you think that there is any way that I can test it with your server then please send me the instructions by mail and I'll try to debug it.

andy44300575 · Jan 22, 2014

HTTPJob package into library can do. Thank you

worksoft.marco · Jun 25, 2015

Erel

After a long time, I decided to upgrade to version 5, but the issue related on this thread remains.

A public server is available for testing, follow the data for access and a example:

Sub Baixar
Dim Job As HttpJob
Dim idemp as string

idemp = "{" & Chr(34) & "empresa" & Chr(34) & ":" & Chr(34) & "01" & Chr(34) & "," & _
Chr(34) & "filial" & Chr(34) & ":" & Chr(34) & "01" & Chr(34) & "," & _
Chr(34) & "vendedor" & Chr(34) & ":" & Chr(34) & "MELVI" & Chr(34) & "," & _
Chr(34) & "senha" & Chr(34) & ":" & Chr(34) & "123" & Chr(34) & "}"

Job.Initialize("CondPagto", Me)
Job.Username = "b4a"
Job.Password = "b4atest"
Job.PostString("http://201.68.9.219:8090/datasnap/rest/TServerMethods1/baixaCondPagto", idemp)
end sub

Thanks for now.
