尝试将图片上传到Firebase存储但未执行?
问题描述:
var img: UIImage!
if self.profileImg.image == #imageLiteral(resourceName: "add_image"){
img = #imageLiteral(resourceName: "add_image")
}else{
img = self.profileImg.image
}
if let imgData = UIImageJPEGRepresentation(img, 0.2){
print(imgData)
let imageUid = NSUUID().uuidString
print(imageUid)
let metaData = StorageMetadata()
print(metaData)
metaData.contentType = "image/jpeg"
DataService.ds.REF_PROFILE_IMAGES.child(imageUid).putData(imgData, metadata: metaData, completion: { (metadata, error) in
if error != nil {
print ("ADAM: UNABLE TO UPLOAD IMAGE TO FIREBASE STORAGE")
}else{
print ("ADAM: SUCCESSFULLY UPLOADED PROFILE IMAGE ")
self.downloadURL = metaData.downloadURL()?.absoluteString
}
})
}else{
print("ADAM: SUMTING WONG")
}
Auth.auth().createUser(withEmail: emailField.text!, password: passwordField.text!) { (user, error) in
if error == nil {
print("ADAM: You have successfully signed up")
// saving the image to storage and link to database
let firstName = self.firstNameField.text
let lastName = self.LastNameField.text
let userName = self.usernameField.text
let profileImageUrl = self.downloadURL
print(profileImageUrl)
let userData = ["provider" : user!.providerID, "FirstName": firstName, "LastName": lastName, "username": userName, "profileImageURL": profileImageUrl]
self.completeSignIn(id: user!.uid, userData: userData as! Dictionary<String, String>)
配置文件图像URL重复返回零,因此不会允许我运行登录功能。当我调试时,我可以看到Dataservice方法被跳过,我不明白为什么:/尝试将图片上传到Firebase存储但未执行?

我正在使用它创建用户并将用户信息存储在Firebase数据库和映像存储中。
func registerUser(withName: String, email: String, password: String, profilePic: UIImage, completion: @escaping (Bool) -> Swift.Void) {
Auth.auth()?.createUser(withEmail: email, password: password, completion: { (user, error) in
if error == nil {
user?.sendEmailVerification(completion: nil)
let storageRef = FIRStorage.storage().reference().child("usersProfilePics").child(user!.uid)
let imageData = UIImageJPEGRepresentation(profilePic, 0.1)
storageRef.putData(imageData!, metadata: nil, completion: { (metadata, err) in
if err == nil {
let path = metadata?.downloadURL()?.absoluteString
let values = ["name": withName, "email": email, "profilePicLink": path!]
FIRDatabase.database().reference().child("users").child((user?.uid)!).child("credentials").updateChildValues(values, withCompletionBlock: { (errr, _) in
if errr == nil {
let userInfo = ["email" : email, "password" : password]
UserDefaults.standard.set(userInfo, forKey: "userInformation")
completion(true)
}
})
}
})
}
else {
completion(false)
}
})
}
你看到为零,因为'putData'是一个异步调用,所以你需要可以调用'createUser'方法里面'putData'关闭或使用完成处理程序,你可以检查此:https://*.com/questions/46356012/firebase-one-of-two-observers-not-working/46356267#46356267 – 3stud1ant3
@ 3stud1ant3我试过在putData完成处理程序中创建用户,但仍然没有运气 – KONADO
