SAPUI5 Cross-origin resource sharing issues while Posting to backend.

Hello SAPUI5 people,

 

I'm still having some issues with posting to the SAP backend.

 

The Problem:

I am using jQuery to post to the SAP backend via the following code:

 

http://pastie.org/5477802

 

I added a debugger to the incoming webservice call in SAP and it says Method: OPTIONS instead of Method: POST.

 

I have tested this from my local webserver & via the sap cloud portal.

 

 

The big But

When I simply run that code via an HTML file in Internet Explorer, and look at the debugger it says Method: POST and adds my data the my table.

 

My local code:  http://pastie.org/5477806

 

Now the big But, when I run the same file in Firefox / Chrome, the Method turns to OPTIONS again.

 

 

What needs to happen (don't know how)


SAP needs to enable cross-origin resource sharing on the online webserver.

Or someone needs to suggest me a better way of doing this.

 

 

Temp Fix (bad practice)


I can replace the Method Options to Method Post, hard coded. But this is dirty nasty code.

 

 

Temp conclusion

Works:

  • Post to SAP Backend via Internet Explorer and simple HTML File

 

Does not Work:

  • Post to SAP Backend via Firefox & Chrome via simple HTML File
  • Post to SAP Backend via IE, FF and Chrome on Local SAP Eclipse Webserver.
  • Post to SAP Backend via IE, FF and Chrome on SAP Cloud Trial account

I hope someone can help me, because I spend a lot of time figuring this out.

 

 

Kind regards,

Vincent
