How to pass arguments to CREATE_STREAM via Slug parameters ?

Hi everyone, I follow the steps in the Uploading Files to SAP GW, Downloading Files from SAP GW - New Techniques and Upload Image to SAP Gateway and Display Image in UI5 - Using New Fileuploader with SAP Gateway.

I want to pass many arguments to create_stream via slug parameters?

I use the following code in SAPUI5.

var oFileUploader = new sap.ui.unified.FileUploader({
                    uploadUrl : "/sap/opu/odata/sap/ZFILE_UPLOAD_TEST_SRV/UserCollection('"+ "burak.oral" +"')/Photo",
                    name: "simpleUploader", 
                    uploadOnChange: false,
                    sendXHR: true,
                    maximumFileSize : 1,
                    useMultipart: false,
                    headerParameters: [
                        new sap.ui.unified.FileUploaderParameter({name: "x-csrf-token", value: sap.ui.getCore().getModel().getHeaders()['x-csrf-token'] }),    
                    ],
                    uploadComplete: function (oEvent) {
                        var sResponse = oEvent.getParameter("response");
                        if (sResponse) {
                            oUploadDialog.close();
                            sap.ui.commons.MessageBox.show("Return Code: " + sResponse, "Response", "Response");
                        }
                    }                    
                });

How to do pass paramater for above code.
