如何在React Native中将视频上传到firebase firestore

Question

我目前可以通过将图像存储在Blob中并将其上传到Firestore来将其上传到Firebase Firestore。除了影片，我该怎么做？我也将它放在Blob中吗？下面是我用来上传图片的代码。

openLibrary = async () => {
 const { status } = await Permissions.askAsync(Permissions.CAMERA_ROLL)
 if (status === 'granted') {
 const image = await ImagePicker.launchImageLibraryAsync({allowsEditing: true})
 if(!image.cancelled){
 const url = await this.props.uploadPhoto(image)
 this.props.updatePhoto(url)
      }
    }
  }
export const uploadPhoto = (image) => {
 return async (dispatch) => {
 try {
 console.log("in upload photo")
 const resize = await ImageManipulator.manipulateAsync(image.uri, [], { format: 'jpeg', compress: 0.1 })
 const blob = await new Promise((resolve, reject) => {
 const xhr = new XMLHttpRequest()
 xhr.onload = () => resolve(xhr.response)
 xhr.responseType = 'blob'
 xhr.open('GET', resize.uri, true)
 xhr.send(null)
      });
 const uploadTask = await firebase.storage().ref().child(uuid.v4()).put(blob)
 const downloadURL = await uploadTask.ref.getDownloadURL()
 return downloadURL
    } catch(e) {
 console.log("in upload photo error")
 console.error(e)
    }
  }
}

您如何尝试下载文件？

也许当您上传视频时，您没有在上传或下载（mp4，mov等）时设置文件类型/扩展名。

尝试添加所需的文件扩展名，请参阅this link。
