为什么我收到paypal系统错误请重试

Question

我正在尝试将 payapal 集成到我的移动应用中。我一直在关注我发现的this tutorial。但是当我尝试付款时，我收到一条错误消息，提示登录失败：系统错误。请再试一次。我不确定问题是什么。我的登录信息是正确的，所以我知道这不是问题。我能得到一些帮助吗？提前致谢。顺便说一下，这是我的代码

 //Main activity

      private static final int PAYPAL_REQUEST_CODE=7171;

    private static PayPalConfiguration config=new PayPalConfiguration().environment(PayPalConfiguration.ENVIRONMENT_PRODUCTION)
            .clientId(Config.PAYPAL_CLIENT_ID);

    @Override
    protected void onDestroy() {
        stopService(new Intent(this, PayPalService.class));
        super.onDestroy();
    }


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_all_in_one);
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR);
        overridePendingTransition(R.anim.fragment_close_exit, R.anim.fragment_fade_enter);
        getWindow().setStatusBarColor(ContextCompat.getColor(this,R.color.black));


        //start paypal service
        Intent intent=new Intent(this,PayPalService.class);
        intent.putExtra(PayPalService.EXTRA_PAYPAL_CONFIGURATION,config);
        startService(intent);
        

@Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if(requestCode==PAYPAL_REQUEST_CODE){
            if(resultCode==RESULT_OK){
                PaymentConfirmation confirmation=data.getParcelableExtra(PaymentActivity.EXTRA_RESULT_CONFIRMATION);
                if(confirmation!=null){
                    try {
                        String paymentDetails=confirmation.toJSONObject().toString(4);
                        startActivity(new Intent(this, PayPalPaymentDetails.class).
                                putExtra("Payment Details",paymentDetails)
                                .putExtra("Amount","5.00")
                        );

                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }

            }else if(resultCode== Activity.RESULT_CANCELED){
                Toast.makeText(this, "Cancel", Toast.LENGTH_SHORT).show();

            }else if(resultCode==PaymentActivity.RESULT_EXTRAS_INVALID){
                Toast.makeText(this, "Invalid", Toast.LENGTH_SHORT).show();

            }

        }

如果您的 PayPal 登录密码中包含“&”，则会出现此错误。确保不要在密码中使用该字符。
