{
"Address" : "dfsswrfdssddsd",
"CurrentDate" : 1484910921411,
"Email" : "a@fg.hh",
"Name" : "abc",
"PhoneNumber" : "53465465765677",

我想删除与键（-Kav_cy_EFZnu5vNWP2g）对应的数据。我尝试了下面的代码，但它不起作用：
模型
func (m *User) DeleteFromDB(ctx context.Context,key string)(bool) {
dB, err := GetFirebaseClient(ctx,"")
if err!=nil{
log.Println("连接错误：",err)
}
err = dB.Child(key).remove();
if err!=nil{
log.Println("删除错误：",err)
return false
}
return true
}
在DeleteFromDB()函数中，我有这个键。

"Email" : "fg@gmail.com",
"Name" : "dcf",
"PhoneNumber" : "9897878787",
"State" : "fdsf",
"Status" : "Completed",
"Zipcode" : "56546"
}
}
i want to delete data corresponding to the key(-Kav_cy_EFZnu5vNWP2g). I have tried below code, but it's not working:
model
func (m *User) DeleteFromDB(ctx context.Context,key string)(bool) {
dB, err := GetFirebaseClient(ctx,"")
if err!=nil{
log.Println("Connection error:",err)
}
err = dB.Child(key).remove();
if err!=nil{
log.Println("Deletion error:",err)
return false
}
return true
}
in DeleteFromDB(), I have the key.

尝试将remove函数更改为以下形式：
dB.Child("/Contacts/" + key).Remove()
英文:
try changing the remove function like this
dB.Child("/Contacts/"+key).Remove()
