Sencha Touch oData Connector for SAP

[skarolus]

Hi i want to get Data with the oData Connector, but there are always an Error Message:
401 (Unauthorized).
My proxy:

proxy: {

            type: 'odata',

            url: 'https://url..../odata/_vti_bin/listdata.svc/News',

            withCredentials: true,

            username: 'username',

            password: 'password'

if I try to open the url in the browser, it works with the credentials.

Are you also trying to do this cross origin?

I disabled the web security of google chrome, I don't think this should be the problem.

Hi,

I am facing the similar issue. This is an authorization error. But when I open the link in the browser in a different tab by providing the credentials, this error is gone. Unfortunately a new error has popped up(Status code 501). Not sure how to resolve this one.

I am encountering the same issue.

Using the error handling from the Flights Unlimited example project, additional error message details were provided: "Logon performed in system ABC, No logon data provided"

Since username and password properties are being provided, I was expecting an invalid logon data message versus a no logon data message and am therefore proceeding with investigating the proxy itself.

Like others, the URL works in Google Chrome with disabled web security and in Firefox with the RESTClient add-on.

proxy: {

            type: 'odata',

            url: 'https://url..../odata/_vti_bin/listdata.svc/News',

            withCredentials: true,

            username: 'username',

            password: 'password'

Your use of listdata.svc seems to suggest you're connecting to SharePoint, not SAP gateway.

If so, the issue may be the authentication method used. If your SharePoint uses e.g. claims based authentication, logon will not work.

I have been trying for many weeks now and concluded that the SAP OData Proxy works fine in browsers, but does not work in a Simulator or on Device. The error that occurs is a 401 error, which states that the credentials were not given.

After launching Chrome with the following parameters:
open -a "Google Chrome" --args --allow-file-access-from-files --disable-web-security
The SAP OData Proxy will work and the username and password are understood, but when packaging for the Simulator, it does not work.

Has anyone got this working, without the need to remove the authentication from the OData service.

Hi,

Did you try to include "useHeaderAuthentication: true"? Like so:

proxy: {
            type: 'odata',
            url: "HTTP://GW.ESWORKPLACE.SAP.COM:80/sap/opu/sdata/iwcnt/activity/ActivityCollection",
            withCredentials: true,
            useHeaderAuthentication: true,  
            username: '<yourusername>',
            password: '<yourpassword>'
        }

Let me know if that works.

Thanks.

Luc,

Perfect, just tried and that did the trick, fantastic, I now have a fully functioning SAP Odata Application using a SAP Hana OData Service on an iOS Device.

Many thanks for your help.
