firebase的json文件就像
{
"users": {
"a540678c0fda89f430bfba480ffe6f40146548bad72c199f8536b167fc58455a" : {
"password" : "2a97516c354b68848cdbd8f54a226a0a55b21ed138e207ad6c5cbb9c00aa5aea",
"phone" : "+91xxxxxxx",
"uid" : "demo"
}
}
}

如何使用ref()获取密码,手机和uid的值。once()。then()语法
答案 0 :(得分:0)
这应该有效:
var ref = firebase.database().ref("users/a540678c0fda89f430bfba480ffe6f40146548bad72c199f8536b167fc58455a");
ref.once("value").then(function(snapshot) {
var user = snapshot.val();
console.log(user.password, user.phone, user.uid);
});
