我试图将一个图像添加到Firebase存储，然后获取该图像的位置，并将其与其他用户配置文件数据一起存储在Firestore文档中。 我试图在用户第一次创建帐户时完成所有这些。 我试图使用图像URL来做这件事，但似乎没有工作。 当我运行下面的代码时，它将注册一个新用户，并将照片添加到Firebase存储中，但是在Firestore数据库中没有创建任何文档。 我做错了什么？
@objc func handleSignUp() {
//Signup properties
guard let email = emailTextField.text else { return }
guard let password = passwordTextField.text else { return }
guard let fullName = fullNameTextField.text else { return }
guard let username = usernameTextField.text?.lowercased() else { return }
Auth.auth().createUser(withEmail: email, password: password) { (authResult, error) in
//Handle error
if let error = error {
print("DEBUG: Failed to create user with error: ", error.localizedDescription)
return
}
guard let profileImg = self.plusPhotoBtn.imageView?.image else { return }
guard let uploadData = profileImg.jpegData(compressionQuality: 0.3) else { return }
let filename = NSUUID().uuidString
//Storage location for photo in Firebase
let storageRef = Storage.storage().reference().child("profile_images").child(filename)
storageRef.putData(uploadData, metadata: nil, completion: { (metadata, error) in
//Handle error
if let error = error {
print("Failed to upload image to Firebase Storage with error", error.localizedDescription)
return
}
})
guard let username = self.usernameTextField.text?.lowercased() else { return }
storageRef.downloadURL { (url, _) in
guard let downloadURL = url else {
print("DEBUG: Profile image url is nil")
return
}
Firestore.firestore().collection("profile_data").addDocument(data: [
"name": fullName,
"username": username,
"profileImageUrl": downloadURL,
"email" : email]) { (err) in
if let err = err {
debugPrint("Error adding document: \(err)")
} else {
self.navigationController?.popViewController(animated: true)
}
}
}
}
}
我认为您应该在“putdata”内部添加“downloadurl”部分。
在完成put data过程之后，您应该尝试获取URL，否则它将失败。
试试这个，看看它是否有效:
@objc func handleSignUp() {
//Signup properties
guard let email = email.text else { return }
guard let password = password.text else { return }
guard let fullName = name.text else { return }
guard let username = name.text?.lowercased() else { return }
createUser(email: email,
password: password,
fullName: fullName,
userName: username)
}
func createUser(email: String, password: String, fullName: String, userName: String) {
Auth.auth().createUser(withEmail: email, password: password) { (authResult, error) in
//Handle error
if let error = error {
print("DEBUG: Failed to create user with error: ", error.localizedDescription)
return
}
guard let profileImg = self.plusPhotoBtn.imageView?.image else { return }
guard let uploadData = profileImg.jpegData(compressionQuality: 0.3) else { return }
let filename = NSUUID().uuidString
//Storage location for photo in Firebase
let storageRef = Storage.storage().reference().child("profile_images").child(filename)
storageRef.putData(uploadData, metadata: nil, completion: { (metadata, error) in
//Handle error
if let error = error {
print("Failed to upload image to Firebase Storage with error", error.localizedDescription)
return
}
guard let metadata = metadata else { return }
guard let username = self.usernameTextField.text?.lowercased() else { return }
storageRef.downloadURL { (url, _) in
guard let downloadURL = url else {
print("DEBUG: Profile image url is nil")
return
}
let data = ["name": fullName,
"username": username,
"profileImageUrl": downloadURL,
"email" : email]
self.addDocument(userData: data)
}
})
}
}
func addDocument(userData: [String: Any]) {
Firestore.firestore().collection("profile_data").addDocument(data: userData) { (err) in
if let err = err {
debugPrint("Error adding document: \(err)")
} else {
self.navigationController?.popViewController(animated: true)
}
}
}
