Hello Everyone, I want to create a custom component which could display the current login user's business data by custom code in Power Apps component framework. But I don't know how to get the current user's ID or Email in the code. Here is my custom code. Could you give me some advice?
import { IInputs, IOutputs } from "./generated/ManifestTypes";
export class ExportExcelComponent implements ComponentFramework.StandardControl<IInputs, IOutputs> {
// PCF framework context, "Input Properties" containing the parameters, control metadata and interface functions.
private _context: ComponentFramework.Context<IInputs>;
// PCF framework delegate which will be assigned to this object which would be called whenever any update happens.
private _notifyOutputChanged: () => void;
// Control's container
private controlContainer: HTMLDivElement;
// button element created as part of this control
private exportButton: HTMLButtonElement;
// label element created as part of this control
private errorLabelElement: HTMLLabelElement;
/**
* Empty constructor.
*/
constructor() {
}
/**
* Used to initialize the control instance. Controls can kick off remote server calls and other initialization actions here.
* Data-set values are not initialized here, use updateView.
* @param context The entire property bag available to control via Context Object; It contains values as set up by the customizer mapped to property names defined in the manifest, as well as utility functions.
* @param notifyOutputChanged A callback method to alert the framework that the control has new outputs ready to be retrieved asynchronously.
* @param state A piece of data that persists in one session for a single user. Can be set at any point in a controls life cycle by calling 'setControlState' in the Mode interface.
* @param container If a control is marked control-type='standard', it will receive an empty div element within which it can render its content.
*/
public init(context: ComponentFramework.Context<IInputs>, notifyOutputChanged: () => void, state: ComponentFramework.Dictionary, container: HTMLDivElement) {
// Add control initialization code
this._context = context;
this._notifyOutputChanged = notifyOutputChanged;
this.controlContainer = document.createElement("div");
//Create an upload button to call the forms recognizer api
this.exportButton = document.createElement("button");
// Get the localized string from localized string
this.exportButton.innerHTML = context.resources.getString("PCF_FormsRecognizerControl_Recognize_ButtonLabel");
this.exportButton.addEventListener("click", this.onExportButtonClick.bind(this));
// Create an error label element
this.errorLabelElement = document.createElement("label");
this.errorLabelElement.setAttribute("id", "lblError");
// Adding the label and button created to the container DIV.
this.controlContainer.appendChild(this.exportButton);
this.controlContainer.appendChild(this.errorLabelElement);
container.appendChild(this.controlContainer);
}
/**
* This button event handler will allow the user to pick the file from the device
* Export the results searched by end-user to excel file
* @param event click event

});
}
