Android Fido2PendingIntentlaunchPendingIntent首次失败，并且连续运行

编程问答 2022-06-11

问题描述

为什么Google的Fido2PendingIntent().launchPendingIntent方法在首次尝试上失败，并显示错误代码：

Security_ERR - The operation is insecure. The incoming request cannot be validated.

而且，成功尝试通常会导致上述呼叫正常工作（提示显示指纹/密码），并且不再出现此错误。

这些是代码的主要摘要：

ListenerRegistration.java：

    try {
        // Get intent for FIDO2 operation.
        Fido2apiclient fido2apiclient = Fido.getFido2apiclient( this.activity );
        Task<Fido2PendingIntent> task = fido2apiclient.getRegisterIntent( pkcco );

        // Send intent back to UI through callback.
        Log.d( TAG,"LISTENERREGISTRATION.java IS Now ATTEMPTING TO OPEN FINGERPRINT/SECRUITY PROMPT" );
        this.fidoDelegate.launchFidoPrompt( Tasks.await( task ),FidoPromptCallback.FIDO2_REGISTRATION );

        // Wait for authenticator to complete.
        this.fidoAuthenticatorLock.acquire();
    } catch( ExecutionException e ) {
        // Threw exception while waiting for authenticator.
        // Pass Fido2AuthenticatorException back to calling class so it can handle error appropriately.
        throw new Fido2AuthenticatorException( this.sFido2AuthenticatorErrorMessage,this.fido2ErrorCode );
    } catch( InterruptedException e ) {
        // Threw exception while waiting for authenticator.
        // Pass Fido2AuthenticatorException back to calling class so it can handle error appropriately.
        throw new Fido2AuthenticatorException( this.sFido2AuthenticatorErrorMessage,this.fido2ErrorCode );
    }

MainActivity.java：

       // Instantiate class to handle VC functionality called by listener.
       this.lo = new ListenerOperations(MainActivity.this,new FidoPromptCallback() {
        @Override
        public void launchFidoPrompt(Fido2PendingIntent fido2Intent,int iOperation) {
            // Determine how to handle authenticator result.
            int iCode;
            if (iOperation == FidoPromptCallback.FIDO2_REGISTRATION) {
                iCode = MainActivity.REQUEST_FIDO2_REGISTER;
            } else if (iOperation == FidoPromptCallback.FIDO2_ASSERTION) {
                iCode = MainActivity.REQUEST_FIDO2_ASSERTION;
            } else {
                // Invalid operation.
                iCode = -1;
            }

            try {
                // Launch the fingerprint dialog by launching the intent from FIDO2 API.
                Log.d( TAG,"MAINACTIVITY.java IS Now ATTEMPTING TO OPEN FINGERPRINT/SECRUITY PROMPT" );
                fido2Intent.launchPendingIntent( MainActivity.this,iCode );
                Log.d( TAG,"MAINACTIVITY.java HAS OPENNED FINGERPRINT/SECRUITY PROMPT WITH NO ERRORS" );

            } catch( IntentSender.SendIntentException e ) {
                // Error launching pending intent for register request.
                Log.d(TAG,"SADFACE - Failed TO OPEN FINGERPRINT FIDO DIALOG");
            } catch (Exception e) {
                Log.d( TAG,"GENERAL EXCEPTION OCCURRED WHEN CALLING fido2Intent.launchPendingIntent" );
                e.printstacktrace();
            }
            Log.d( TAG,"MAINACTIVITY.java END OF launchFidoPrompt()" );
        }

关于失败（和成功）的日志如下所示（因为即使收到Security_ERR错误之后，也不会抛出任何异常）

我的代码没有得到任何异常通知的事实，使我相信问题出在对Fido2PendingIntent().launchPendingIntent的调用之内。

请注意，此代码现在例外：
