Question

我遵循了文档https://firebase.google.com/docs/admin/setup?authuser=0

的步骤

但是代码的“ GoogleCredentials.fromStream（serviceAccount）”部分；它会停止应用程序，并且不返回任何内容，甚至不会返回错误消息。

我已经包含了以下库

firebase-admin-6.8.1.jar
google-auth-library-credentials-0.15.0.jar
google-auth-library-oauth2-http-0.15.0.jar
appengine-api-1.0-sdk-1.9.74.jar

请给我一些帮助，谢谢

        String token=null;
        FirebaseOptions options=null;
        FileInputStream serviceAccount=null;                    
        try {
            serviceAccount = new FileInputStream(Aplicacion.ruta_firebase_js);            
        }catch(FileNotFoundException ex) {
            log("Ruta de clave de firebase no encontrada: "+ex.getMessage());
        }           

        if(serviceAccount!=null){ 
            try {

                GoogleCredentials gc=GoogleCredentials.fromStream(serviceAccount);                
                log(gc.toString());
                options = new FirebaseOptions.Builder()
                        .setCredentials(gc)
                        .setDatabaseUrl("https://xxxxx-xxxxxx.firebaseio.com")
                        .build();
            } catch(FileNotFoundException ex) {
                log("Ruta de clave de firebase no encontrada: "+ex.getMessage());
            }catch (IOException ex){ 
                log("Error autenticando en Firebase: "+ex.getMessage());
            } 
        }


        if(options!=null){ 
            FirebaseApp.initializeApp(options);                    
            try {
                String uid = "Rocco-ergvrw98";
                token = FirebaseAuth.getInstance().createCustomToken(uid);
                HashMap p=new HashMap();
                p.put("accion", "tokenfirebase");
                p.put("token", token);
                Rocco.servidor_enlinealizate.enviar(indice, p); 

            } catch (FirebaseAuthException ex) {
                log("Error obtenmiendo token: "+ex.getMessage());
            };
        }
        return token;
    }
