Question

我有一个用角度2写的服务，用于将图像上传到firebase。代码是：

import {Injectable} from "@angular/core";
import {AngularFireDatabase} from "angularfire2/database";
import {FileUpload} from "../objects/file";
import * as firebase from 'firebase';
@Injectable()
export class UploadFileService {
  private basePath = '/uploads';
  constructor(private db: AngularFireDatabase) {}
  pushFileToStorage(fileUpload: FileUpload, progress: {percentage: number}) {
    const storageRef = firebase.storage().ref();
    const uploadTask = storageRef.child(`${this.basePath}/${fileUpload.file.name}`).put(fileUpload.file);

    uploadTask.on(firebase.storage.TaskEvent.STATE_CHANGED,
      (snapshot) => {
        // in progress
        const snap = snapshot as firebase.storage.UploadTaskSnapshot;
        progress.percentage = Math.round((snap.bytesTransferred / snap.totalBytes) * 100);
      },
      (error) => {
        // fail
        console.log(error);
      },
      () => {
        // success
        fileUpload.url = uploadTask.snapshot.downloadURL
        fileUpload.name = fileUpload.file.name
        this.saveFileData(fileUpload);
      }
    );
  }

  private saveFileData(fileUpload: FileUpload) {
    this.db.list(`${this.basePath}/`).push(fileUpload);
  }
}

此代码在＆＃34; firebase.storage＆＃34;上给出了错误。函数＆＃34;属性存储在类型firebase static＆＃34;

上不存在

我已经阅读了一篇关于这句话的帖子，可以通过将firebase导入更改为＆＃34;声明var firebase＆＃34;来解决这个问题。但这没效果。

Answer 1

将您的行更改为：

import menu from 'menu';

第一行导入类型。第二个只进口火力储存库。

角度4中无法识别Firebase功能
