我试图让Firebase数据库组件与我的iOS项目一起工作,当我的代码(包含在下面)执行时,它将输出"成功"消息,但数据库未被修改。我还包括了一个"错误"我收到了我的Xcode日志。
感谢您的帮助!
public IEnumerator GetProfile() {
Task < DataSnapshot > task = FirebaseDatabase.DefaultInstance.GetReference("users/" + _currentUser.UserId).GetValueAsync();
while (!task.IsFaulted && !task.IsCanceled && !task.IsCompleted)
yield
return null;
if (task.IsCompleted) {
//set data
Debug.Log("has data");
DataSnapshot snapShot = task.Result;
if (snapShot.Value == null) {
Debug.Log("no value");
Task postNew = FirebaseDatabase.DefaultInstance.RootReference.Child("users").Child(_currentUser.UserId)
.SetRawJsonValueAsync(JsonConvert.SerializeObject(new User()));
while (!postNew.IsFaulted && !postNew.IsCanceled && !postNew.IsCompleted)
yield
return null;
if (postNew.IsFaulted) {
Debug.Log(postNew.Exception.ToString());
} else
Debug.Log("suceeded");
}
} else {
Debug.Log(task.Exception.ToString());
/*_root.Child("users").Child(_currentUser.UserId)
.SetRawJsonValueAsync(JsonConvert.SerializeObject(new User()));*/
}
}

原来我发送的JSON字符串的值为&#34; null&#34;所以写得无声无息。 (如果另一位开发人员帮我找到它)。
