使用Firebase更新个人资料图像

Question

我如何重写此代码以设置用户个人资料图像，我正在尝试更新用户个人资料，但用户图像显示为空白。我相信我格式化该代码没有任何错误。格式化此代码以更新用户个人资料图像的正确方法是什么？

let localFile = URL(string: "https://firebasestorage.googleapis.com.appspot.com")!
            let riversRef = Storage.storage().reference().child("image/jpeg")
            let uploadTask = riversRef.putFile(from: localFile, metadata: nil) { metadata, error in
            guard let metadata = metadata else {
                                return
                                             }

        riversRef.downloadURL { (url, error) in
        guard let downloadURL = url else {
                                return
                                               }

                            //here's where we have the url to the file in storage and can update
                            //  the users profile

                                  }

                          }



        let changeRequest = Auth.auth().currentUser?.createProfileChangeRequest()
        let someUrl = URL(string: "https://firebasestorage.googleapis.com6.appspot.com")
        changeRequest?.displayName = "username"
        changeRequest?.photoURL = someUrl
        changeRequest?.commitChanges { (error) in
            if let err = error {
                print(err.localizedDescription)
                return
            }
            print("success!")
        }

这是您可以用来上传图像的代码。

        let imageName = "images/\(Date().timeIntervalSince1970).jpg"
        let profilePicRef = Storage.storage().reference().child(imageName)
        _ = profilePicRef.putData(data, metadata: nil) { (metadata, error) in
            guard let metadata = metadata else {
                // Uh-oh, an error occurred!
                completion(false, nil)
                return
            }
            // Metadata contains file metadata such as size, content-type.
            _ = metadata.size
            // You can also access to download URL after upload.
            profilePicRef.downloadURL { (url, error) in
                guard let downloadURL = url else {
                    completion(false, nil)
                    return
                }
                completion(true, downloadURL.absoluteString)
                print(downloadURL.absoluteString)
            }
        }
