Making request error from android via sap gateway services

[former_member204321]

hi,

i'm getting following error while work with post gateway service from the android. HTTP request error. I'm using the following code to update the data via POST gateway service.

mParameters = new SDMConnectivityParameters();

mParameters.setUserName(<username>);

mParameters.setUserPassword(<password>);

mPreferences = new SDMPreferences(_context, Utility.getLogger());

ISDMRequestManager mRequestManager = new SDMRequestManager(Utility.getLogger(), mPreferences, mParameters, 3, mSecurity);

ISDMRequest request = new SDMBaseRequest();

request.setListener(this);

request.setRequestUrl(_serviceURL);

request.setRequestMethod(ISDMRequest.REQUEST_METHOD_POST);

request.setPriority(ISDMRequest.PRIORITY_HIGH);

Map<String, String> headers = new HashMap<String, String>();

headers.put("Content-Type", "application/atom+xml");

headers.put("X-Requested-With", "XMLHttpRequest");

request.setHeaders(headers);

request.setData(requestBody.getBytes());

request.setRequestUrl(_serviceURL);

mRequestManager.makeRequest(request);

_response = "pending";

while (true)

{

                              if (_response != "pending")

   {

     break;

   }

                    }

                    if (_response.equalsIgnoreCase("error"))

                    {

                              ThrowServiceException(_ISDMRequestStateElement);

                    }

                    else if (_response.equalsIgnoreCase("error400"))

                    {

                              throw new CustomException(respBody);

                    }

                     return _response;

Hi Pavan,

I have a few questions?

1) Does the request you are trying to POST work in the REST client?

2) Does your gateway support XCSRF tokens? If, so then this must be enabled in your code as a header before doing a POST operation.

Hi Pavan,

the error may be due to any one of the below two reasons:

1. The authentication parameters (username/password) being sent during POST might be wrong.

2. The collection on which you are trying POST might not support the POST operation.

You can verify the authentication credentials or whether the POST operation is enabled on the collection by tring the same operations using REST client.

Hi Sachin,

I'm passing the right credentials and successfully doing this POST operation via firefox (rest client). While proceeding from source hitting with the above error.

Thanks for reply 🙂

Hi Pavan,

    Since you are telling it works from the REST client, it would be good to cross check the xml body that is being sent through the source with the body that is given in the REST client. So, please check the value of the "requestbody" variable used in

     request.setData(requestBody.getBytes());

Also, the headers and the url on which this request is being fired by having some log statements. In the code which is given i could not see how the requestBody is being initialized.

Hope this helps.

Regards,

Deepika.

Hi Deepika,

There is no problem with payload(requestBody). I tested, its working fine. I'm adding same headers where i'm using in firefox (rest client).

Hi Pavan,

are you able to perform GET request successfully? If not,  I s8uggest you to verify your application code against code given @ http://scn.sap.com/docs/DOC-27410.

If GET is already working for you, please enable the payload loggin. Perform a POST request and revert back with logs.

Steps:

1. Domain>>DomainName>>Log>>Settings>>New >> Enter a name

2.Select "Application Connection" and chose your User

3. Select "payload" and chose "request response"

4. Select "Enable after creation"

Save the settings.

Change the log level at Server>>Logs>>Unwired Server>>Settings>>Proxy>>Debug.

Fire a new request from your application.

Under Domain>>DomainName>>Log>>General>>Proxy, click on retrive to display the latest logs:
