SUP 2.1 how to upload a picture from native app to back-end through SUP?

[Former Member]

Hi everyone,

We are currently making a Proof of Concept based on Sybase Unwired Platform 2.1.

The mobile application is a native iOS application & should be able to take a picture and upload it into the backend.

The backend already exists and has Rest/XML web services and a Rest service (Multipart/Post) for the picture upload.

However we are experiencing problems to integrate the picture upload service in SUP.

How can this service be integrated into the platform in our scenario ?

More generally what is the best practice in SUP when an upload of binary data (picture for instance) from the device to the server is required ?

Thank you

Hi,

     You could try to convert the image to NSData and then do a POSTto the backend and that should suffice.

Hi,

We are currently trying to upload jpeg image file taken by the device camera. Our existing backend service is a accepting http POST request with multipart/form-data.

So we have 2 questions:

• Can SUP integrate such services ?
• If not, how such a use case (upload of a picture to a backend system) should be implemented in a SUP environment ?

Thanks

Hi,

You can very much upload the RAW data to the backend with SUP 2.1.2, if your webservice is accepting the NSData there should not be any problem, I hope you are writing the NSData in your POST body, you might have to check RequestHeader, probably tools like charles proxy  will help to intercept.

Can you clarify further the data types you are using for the picture etc? Thanks
