我有这个json数据库
{
"shops" : {
"7" : {
"cod1" : {
"name" : "name3",
"description" : "xxx",
},
"cod2" : {
"name" : "name2",
"description" : "xxx",
},
"cod3" : {
"name" : "name1",
"description" : "xxx",
},
我需要迭代快照以获取cod1,cod2,cod3,我需要为我之前不知道的那些代码做一些事情
public void load(string city){
//city is number 7 in this case;
Firebase.Auth.FirebaseUser user = auth.CurrentUser;
FirebaseDatabase.DefaultInstance
.RootReference.Child ("shops").Child (city)
.GetValueAsync ().ContinueWith (task => {
if (task.IsFaulted) {
// Handle the error...
} else if (task.IsCompleted) {
DataSnapshot snapshot = task.Result;
int i = 0;
foreach (DataSnapshot shop in snapshot.Children) {
debug.text = "\nstarting with #" + i.ToString () + ": " + shop.Key+";\n";
i++;
}
}
});
我需要debug.text来显示"从#1开始:cod1"然后再使用cod2和cod3
现在我得到类似的东西#34;从#1:7开始#34;这是那些代码的父母的关键
有没有办法获取这些代码?

嗯,首先,你的JSON并没有真正按照它应该的格式化。如果您想要准确地返回数据," shop"应该是一个数组,而不是一个对象。像这样:
"shops" : [
"cod1" : {
"name" : "name3",
"description" : "xxx"
},
"cod2" : {
"name" : "name2",
"description" : "xxx"
},
"cod3" : {
"name" : "name1",
"description" : "xxx"
}
]
目前,"商店"是一个对象,它有一个子对象" 7",它是cod1,cod2和cod3的父对象。这也是你看到" 7"的原因。
