为什么要更新pod之后，我是否继续获取类型为'StorageMetadata'的值没有成员'downloadURL'？

Question

我知道这是因为不再使用StorageMetadata。我看到了类似的问题的其他一般性答案，指向此Firebase文档。：https://firebase.google.com/docs/storage/ios/upload-files我尝试将其应用于我的代码，但不起作用。我应该如何将其应用于当前功能？

{




        let uid = Auth.auth().currentUser!.uid
        let newPostRef = Database.database().reference().child("people").child(uid).child("PhotoPosts")
        let newPostRef1 = Database.database().reference().child("people").child(uid).child("PhotoPosts1")


        let newPostKey = newPostRef.key



        if let imageData = image.jpegData(compressionQuality: 0.001){

            let imageStorageRef = Storage.storage().reference().child("images").child(uid)


            let newImageRef = imageStorageRef.child(newPostRef.key!)
            let newImageRef1 = imageStorageRef.child(newPostRef1.key!)


            newImageRef.putData(imageData).observe(.success, handler: {(snapshot) in
                self.imageDownloadURL = snapshot.metadata?.downloadURL()?.absoluteString
                newPostRef.setValue(self.imageDownloadURL as Any)


            })



            newImageRef1.putData(imageData).observe(.success, handler: {(snapshot) in
                self.imageDownloadURL = snapshot.metadata?.downloadURL()?.absoluteString

                let keyToPost = Database.database().reference().child("people").child(uid).childByAutoId().key
                let f1: [String: Any] = [(keyToPost) : self.imageDownloadURL as Any]

                newPostRef1.updateChildValues(f1)




                               })


            let caption = ServerValue.timestamp() as! [String : Any]
            Database.database().reference().child("people").child(uid).child("caption").setValue(caption)


        }

    }

就像我提到的那样，我尝试将firebase文档应用于函数，如下所示。它仍然给出基本相同的错误。我要去哪里错了？

 func save() {




        let uid = Auth.auth().currentUser!.uid
        let newPostRef = Database.database().reference().child("people").child(uid).child("PhotoPosts")
        let newPostRef1 = Database.database().reference().child("people").child(uid).child("PhotoPosts1")


        let newPostKey = newPostRef.key



        if let imageData = image.jpegData(compressionQuality: 0.001){

            let imageStorageRef = Storage.storage().reference().child("images").child(uid)


            let newImageRef = imageStorageRef.child(newPostRef.key!)
            let newImageRef1 = imageStorageRef.child(newPostRef1.key!)
            newImageRef.downloadURL { url, error in
              if let error = error {



              } else {

                newImageRef.putData(imageData).observe(.success, handler: {(snapshot) in
                                  self.imageDownloadURL = snapshot.metadata?.downloadURL()?.absoluteString
                                  newPostRef.setValue(self.imageDownloadURL as Any)


                              })
                // Here you can get the download URL for 'simpleImage.jpg'
              }
            }

....

Answer 1

您得到：

类型“ StorageMetadata”的值没有成员“ downloadURL”

[如果您查看documentation for StorageMetadata，您会发现它确实没有StorageMetadata成员。该成员已删除2018年5月的SDK更新，因此早已消失。

downloadURL的文档中显示了获取下载URL的正确方法：

uploading data

在您的情况下，类似于：

// Upload the file to the path "images/rivers.jpg"
let uploadTask = riversRef.putData(data, metadata: nil) { (metadata, error) in
  guard let metadata = metadata else {
    // Uh-oh, an error occurred!
    return
  }
  // Metadata contains file metadata such as size, content-type.
  let size = metadata.size
  // You can also access to download URL after upload.
  riversRef.downloadURL { (url, error) in
    guard let downloadURL = url else {
      // Uh-oh, an error occurred!
      return
    }
  }
}
