如何检查特定的 FirebaseFirestore 错误代码?
How to perform a check for a particular FirebaseFirestore error code?
我有以下代码:
db.collection("property").document(userUID).update(propertyRoot).addOnSuccessListener(
new OnSuccessListener<Void>(){
@Override
public void onSuccess(Void aVoid)
{
//Success
}
}
).addOnFailureListener(
new OnFailureListener(){
@Override
public void onFailure(@NonNull Exception e){
//Create a new collection and set
}
}
);
如果集合已经存在,我想更新我的 Firestore 数据库。否则,我希望 Firestore 创建一个新集合。
我只想在找不到该集合时才创建一个新集合。本质上,我想像这样进行检查:
db.collection("property").document(userUID).update(propertyRoot).addOnSuccessListener(
new OnSuccessListener<Void>(){
@Override
public void onSuccess(Void aVoid)
{
//Success
}
}
).addOnFailureListener(
new OnFailureListener(){
@Override
public void onFailure(@NonNull Exception e){
if(e.errorCode == FirebaseFirestoreException.NOT_FOUND)
{
//Create a new collection and set
}
}
}
);
我怎样才能实现这个目标?
如果您将异常转换为 feedbackFirebaseFirestoreException
object and then check its getCode()
value against the possible Firestore error codes,那应该是可能的。
所以像这样:
public void onFailure(@NonNull Exception e){
if (e is FirebaseFirestoreException) {
if ((e as FirebaseFirestoreException).getCode() == FirebaseFirestoreException.Code.NOT_FOUND)
{
//Create a new collection and set
}
}
}
我有以下代码:
db.collection("property").document(userUID).update(propertyRoot).addOnSuccessListener(
new OnSuccessListener<Void>(){
@Override
public void onSuccess(Void aVoid)
{
//Success
}
}
).addOnFailureListener(
new OnFailureListener(){
@Override
public void onFailure(@NonNull Exception e){
//Create a new collection and set
}
}
