NativeScript Square POS

此插件允许您通过 Square POS 应用从您的移动应用程序接受 Square 支付。这是使用仅限于少数国家的 Square API 的替代方案。目前，仅实现了 Android，并且演示仅适用于 Angular，欢迎您的贡献。

先决条件 / 要求

// test.component.ts
import {
SquarePos,
SquareChargeEventData,
SquareCurrencies,
} from  "nativescript-square-pos";

@Component({
selector:  "Test",
templateUrl:  "./test.component.html",
})

export class  AppComponent {

	public currency: SquareCurrencies = "CAD";
	public applicationId: string = "YOUR_SQUARE_APPLICATION_ID";
	public squarePos: SquarePos = new  SquarePos(this.applicationId);  

	public result: string = "";
	public isAppInstalled: boolean;

	constructor(private  ngZone: NgZone) {
		// Add event listeners for transactions
		this.ngZone.run(() => {
			this.squarePos.on(
				"squareChargeUnknownError",
				this.onSquareChargeUnknownError,
				this
			);

			this.squarePos.on(
				"squareChargeSuccess",
				this.onSquareChargeSuccess,
				this
			);

			this.squarePos.on(
				"squareChargeError",
				this.onSquareChargeError,
				this
			);
		});
		this.isAppInstalled = this.squarePos.isAppInstalled();
	}

	public onTransaction(amount: number): void {
		try {
			this.squarePos.startTransaction(amount, this.currency);
		} catch (e) {
			this.result = "An error occured while launching Square Point of Sale app.";
		}
	}

	public onAppInstall(): void {
		this.squarePos.openAppInstallation();
		const onResume = (args) => {
			this.isAppInstalled = this.squarePos.isAppInstalled();
			app.off(app.resumeEvent, onResume);
		};
		app.on(app.resumeEvent, onResume);
	}

	private onSquareChargeUnknownError(data: SquareChargeEventData) {
		this.ngZone.run(() => {
			this.result = "An unknown error occured. Square Point of Sale was uninstalled or stopped working.";
		});
	}

	private onSquareChargeSuccess(data: SquareChargeEventData) {
		this.ngZone.run(() => {
			this.result = `Transaction ${data.object.success.clientTransactionId} was successfully completed.`;
		});
	}

	private onSquareChargeError(data: SquareChargeEventData) {
		this.ngZone.run(() => {
			this.result = `The transaction was not completed. The error was ${data.object.error.code}: ${data.object.error.debugDescription}.`;
		});
