Question

我使用节点js express和firebase创建了一个Web应用程序。我创建了一个将文件上传到firebase的表单，但是当我尝试指南上的内容时，它会出错...

var firebase = require('firebase');

var config = {
  apiKey: "----------------------------------",
  authDomain: "----------------------------------",
  databaseURL: "-",----------------------------------
  projectId: "---------",
  storageBucket: "----------------",
  messagingSenderId: "---------------"
};

firebase.initializeApp(config);

module.exports = firebase;

// Get a reference to the storage service, which is used to create references in your storage bucket
var storage = firebase.storage();

// Create a storage reference from our storage service
var storageRef = storage.ref();

这是我用于在节点js上使用firebase的设置。

var storage = firebase.storage();
                       ^
TypeError: firebase.storage is not a function

这是我从控制台收到的错误。搜索后他们说我需要使用google-cloud npm。所以我的问题是，如果我在我的节点上安装google-cloud，我是否需要在google云平台上创建一个帐户？..

使用节点js google-cloud软件包而不是firebase来存储文件，视频等。现在firebase存储与Nodejs不兼容，这就是为什么你会收到这个错误^，你可以做类似这样的事情使用google-cloud： -

public class MyBottomsheetBehaviour extends BottomSheetBehavior {

    int lastY = 0;

    MyBottomsheetBehaviour() {
        super();
    }

    @Keep
    public MyBottomsheetBehaviour(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public boolean onInterceptTouchEvent(CoordinatorLayout parent, View view, MotionEvent event) {

        int dy = 0;
        boolean shouldWeConsumeIt = false;

        if (event.getAction() == MotionEvent.ACTION_DOWN) {
            lastY = (int) event.getY();
        } else if (event.getAction() == MotionEvent.ACTION_CANCEL || event.getAction() == MotionEvent.ACTION_UP) {
            lastY = 0;
        } else if (event.getAction() == MotionEvent.ACTION_MOVE) {
            dy = (int) event.getY() - lastY;
        }
        Log.d("Swapnil", "onInterceptTouchEvent() event Y=" + event.getY() + " x=" + event.getX() + getActionType(event.getActionMasked()) + view.getClass().getSimpleName() + "dy=" + dy);
        if (view instanceof FrameLayout) {

            View child = ((ViewGroup) ((FrameLayout) view).getChildAt(0)).getChildAt(0);
            LinearLayoutManager manager = (LinearLayoutManager) ((RecyclerView) child).getLayoutManager();

            if (manager.findFirstCompletelyVisibleItemPosition() == 0 && dy > 0) {

                shouldWeConsumeIt = true;
                int parentHeight = view.getHeight();

                ViewCompat.offsetTopAndBottom(view, dy);
            } else if (manager.findFirstCompletelyVisibleItemPosition() == 0) {
                int height = ((View) view.getParent()).getHeight();
                int top = view.getTop();
                if ((event.getAction() == MotionEvent.ACTION_CANCEL || event.getAction() == MotionEvent.ACTION_UP) && top < (height >> 2)) {
                    view.setTop(0);
                    setState(BottomSheetBehavior.STATE_EXPANDED);
                } else if ((event.getAction() == MotionEvent.ACTION_CANCEL || event.getAction() == MotionEvent.ACTION_UP)) {
                    setState(BottomSheetBehavior.STATE_COLLAPSED);
                }
            }
        }
        if (event.getAction() == MotionEvent.ACTION_MOVE) {
            lastY = (int) event.getY();
        }
        if (!shouldWeConsumeIt)
            return super.onInterceptTouchEvent(parent, view, event);

        return true;
    }

    @Override
    public boolean onTouchEvent(CoordinatorLayout parent, View child, MotionEvent event) {
        return super.onTouchEvent(parent, child, event);
    }

    private String getActionType(int eventType) {

        StringBuilder builder = new StringBuilder();
        if (eventType == MotionEvent.ACTION_DOWN)
            builder.append(" DOWN");
        else if ((eventType & MotionEvent.ACTION_UP) == MotionEvent.ACTION_UP)
            builder.append(" UP");
        else if ((eventType & MotionEvent.ACTION_CANCEL) == MotionEvent.ACTION_CANCEL)
            builder.append(" CANCEL");
        else if ((eventType & MotionEvent.ACTION_MOVE) == MotionEvent.ACTION_MOVE)
            builder.append(" MOVE");

        return builder.toString();
    }
}

然后在项目中使用存储，这是一个示例代码： -

npm install --save google-cloud

这里的链接有完整的指南如何做google-cloud的东西。

const gcloud = require('google-cloud');

const storage = gcloud.storage({
projectId: //project id here,
keyFilename: //service account credentials here,
});

const storagebucket = storage.bucket('projectID.appspot.com');

使用节点js抛出firebase web上的文件抛出错误firebase.storage不是一个函数
