Firebase 自定义登录失败 (JavaScript)
Firebase custom login fails (JavaScript)
我正在尝试开始使用 firebase,现在开始使用它的安全部分。我试图让它尽可能简单,以便开始使用来自 Firebase 网站的指南和代码片段。
为了简单起见,我有一个包含密码 (id "Code") 和用户输入字段 (id "Door") 的网页。如何检查字段 "Code" 中输入的密码是否等于节点 https://mydatabase.firebaseio.com/loapp_users/BAAJ/password 中已存储的密码,BAAJ 是节点 loapp_users 中存储的用户之一的用户 ID,都有子节点 "password"?
下面的代码似乎无法解决问题。
$(document).ready(function(){
// Monitoring User Authentication State
// Use the onAuth() method to listen for changes in user authentication state
// Create a callback which logs the current auth state
function authDataCallback(authData) {
if (authData) {
console.log("User " + authData.uid + " is logged in with " + authData.provider);
} else {
console.log("User is logged out");
}
}
// Register the callback to be fired every time auth state changes
var ref = new Firebase("https://mydatabase.firebaseio.com");
ref.onAuth(authDataCallback);
$("#logout").click(
function logout() {
ref.unauth();
ref.offAuth(authDataCallback);
}
);
// LOGIN
// The code to authenticate a user varies by provider and transport method, but they all have similar signatures and
// accept a callback function. Use it to handle errors and process the results of a successful login.
// Create a callback to handle the result of the authentication
function authHandler(error, authData) {
if (error) {
console.log("Login Failed!", error);
} else {
console.log("Authenticated successfully with payload:", authData);
}
};
$("#login").click(
function() {
var usersRef = new Firebase("https://mydatabase.firebaseio.com/loapp_users");
// Authenticate users with a custom Firebase token
var _user = $("#Door").val();
var _level = "docent";
var _password = $("#Code").val();
var userRef = usersRef.child(_user);
// Attach an asynchronous callback to read the data at our user reference
userRef.on("value", function(snapshot) {
console.log(snapshot.val());
if (snapshot.val().child("password").text() == _password) {
ref.authWithCustomToken("eyJ0e....etc...mlhdCI6MTQyOTM4Mzc0M30.Vn1QF7cRC6nml8HB9NAzpQXJgq5lDrAie-zIHxtOmFk", authHandler);
} else {
console.log("Gebruikersnaam en code komen niet overeen")
}
}, function (errorObject) {
console.log("The read failed: " + errorObject.code);
});
}
);
});
snapshot.val().child("password").text()
应该改为:
snaphot.val().password
然后就可以了。
