How to Authenticate the API for Windchill Odata connector in Thingworx when using SSO Authentication

[VV_14105315]

Hi Folks,

I have a requirement to download the files of Windchill objects into Thingworx repository. I am getting the Link of files inside Thingworx using Odata Connectors. I am able to generate the file in Repository but when I try to open the file getting error "Failed to load PDF document."

Below is the code I am using :

// result: JSON

let inputJson = Things["ptc-windchill-integration-connector"].downloadAsZip({

respondWithZip: false /* BOOLEAN {"dataShape":""} */,

$expand: undefined /* STRING {"dataShape":""} */,

    objectId: <objectId>

});

// result: JSON

let csrf = Things["Thing.ODataConnector.ProdMgmt_TH"].GetCSRFToken({

$select: undefined /* STRING {"dataShape":""} */

});

    item = inputJson.items[0];

let params = {

url: <file_url> /* STRING */ ,

headers: {

"CSRF_NONCE": <Nonce token>,

                "Accept": "*/*",

                "X-Requested-With": "XMLHttpRequest"

}

        };

// result: BLOB

let binaryContent = Resources["ContentLoaderFunctions"].LoadBinary(params);

    result = binaryContent;

    let fullPath = "/test4/" + item.name;

    Things["SupportRepository"].SaveBinary({

path: fullPath /* STRING */,

content: binaryContent /* BLOB */

});

What is wrong in my code to authenticate it while downloading it in Thingworx Repository.

Thanks in advance.

Regards,

VV

Hello VV,

You should be getting the CSRF_NONCE token first and then pass it to subsequent calls - see example bellow:

let ParamA = {            
    url: Windchill_URL + "/servlet/odata/v3/PTC/GetCSRFToken()",
    ...
};    
const NONCE_VALUE = Resources["ContentLoaderFunctions"].GetJSON(ParamA);
...
let ParamB = {            
    ...
    headers: {
        ...
        CSRF_NONCE: NONCE_VALUE
    }
};
result = Resources["ContentLoaderFunctions"].PostJSON(ParamB);

 If you still get some error it would be helpful if you provide ThingWorx/WC log snippets.

Yes Using the Nonce token I fetch the objects then bearer token I download the file in repository. Thank you so much.
