SAPUI5 sends a OPTIONS HTTP Request Method instead of GET


We are developing a application using SAPUI5 Development Kit ver 1.12. The Data is obtained from a Netweaver Gateway system. When the SAPUI5 Framework instantiates the ODataModel Object it attempts to make a connection to the URI which has been specified in the URL.

In Chrome ver 27, when the oDATAModel Object is instantiated, this leads to a OPTIONS request going to the Netweaver Gateway. i.e. the Request Method in the HTTP Header is OPTIONS and not GET or PUT. This OPTIONS request fails with HTTP error code 401, Unauthorized.

The oData Service requires Authentication before it can be used.

We are passing the Username and password while creating the oDataModel Object, i.e. in its constructor. Also our Sync is not Asynchronous.

The JS code snippet from the View is given below

var oDATAServiceURL = "http://server/ias_relay_server/client/rs_client.dll/ODATAFARM/sap/opu/odata/sap/Z_OURSERVICE";var oDATAServiceUserName = "NetWeaverGatewayUserID";var oDATAServicePassword = "PasswordOfNetWeaverGatewayUserID";var myODATAModel = new sap.ui.model.odata.ODataModel(oDATAServiceURL, false, oDATAServiceUserName, oDATAServicePassword, null);

Can anybody let me know what do I have to do to resolve this issue?

    Hi Amardeep,

    Take a look at the link below where it explains the "preflighted" requests.

    "preflighted" requests first send an HTTP OPTIONS request header to the resource on the other domain, in order to determine whether the actual request is safe to send. Cross-site requests are preflighted like this since they may have implications to user data

    • Hi Prabhuarul,

      Your application on the server side must be able to handle the OPTIONS http method and return the http response header "Access-Control-Allow-Origin" defining which origin is allowed to access your application via CORS (cross-origin resource sharing).

      You can find more information about this here.
