[英]Passport.js Execution
I have been looking at some passport.js
tutorials online but haven't grasped a clear understanding of what is happening.我一直在网上查看一些
passport.js
教程,但还没有清楚地了解正在发生的事情。 Can someone help me clear my doubts below?有人可以帮我清除下面的疑问吗? Please read the paragraph at the bottom first.
请先阅读底部的段落。
So assuming I set up everything correctly, this is the login strategy:所以假设我正确设置了一切,这是登录策略:
passport.use('login', new LocalStrategy({
passReqToCallback : true
},
function(req, username, password, done) {
// check in mongo if a user with username exists or not
User.findOne({ 'username' : username },
function(err, user) {
// In case of any error, return using the done method
if (err)
return done(err);
// Username does not exist, log error & redirect back
if (!user){
console.log('User Not Found with username '+username);
return done(null, false,
req.flash('message', 'User Not found.'));
}
// User exists but wrong password, log the error
if (!isValidPassword(user, password)){
console.log('Invalid Password');
return done(null, false,
req.flash('message', 'Invalid Password'));
}
// User and password both match, return user from
// done method which will be treated like success
return done(null, user);
}
);
}));
Now in my app.js (server) I have this as one of my routes:现在在我的 app.js(服务器)中,我将它作为我的路线之一:
/* Handle Login POST */
router.post('/login', passport.authenticate('login', {
successRedirect: '/home',
failureRedirect: '/',
failureFlash : true
}));
Now in my AJS file:现在在我的 AJS 文件中:
app.controller('loginController', function($scope) {
var user = $resource('/login');
$scope.createUser = function() {
var User = new user();
User.username = $scope.usernameVar;
User.password = $scope.passwordVar;
User.save();
}
});
Please read this first (Instead of going through the code first):请先阅读此内容(而不是先阅读代码):
So when the user clicks on the login button on the login page the createUser
function above is run (in my AJS file).因此,当用户单击登录页面上的登录按钮时,会运行上面的
createUser
函数(在我的 AJS 文件中)。 Then I create a resource object for the endpoint '/login'
and when I call save on that it will run the route for that '/login'
endpoint on my server (app.js).然后我为端点
'/login'
创建一个资源对象,当我调用 save 时,它将在我的服务器(app.js)上运行该'/login'
端点的路由。 Then in my server it will passport.authenticate('login', ...
which will run the passport middleware.然后在我的服务器中,它将
passport.authenticate('login', ...
它将运行passport 中间件。
Now my question is:现在我的问题是:
In the passport.use('login'...
strategy where the do values for the variables req, username, and password
come from in the callback to that strategy. Do I have to explicitly pass the username and password the user enters in the textfield on my front end. Like I have a two way data binding for those two textfields in AJS view. If so how do I pass those username and password values?在
passport.use('login'...
策略中,变量req, username, and password
的do 值来自该策略的回调中。我是否必须明确传递用户在我前端的文本字段。就像我在 AJS 视图中对这两个文本字段进行双向数据绑定一样。如果是这样,我该如何传递这些用户名和密码值?
Do these two lines in my AJS controller User.username = $scope.usernameVar;
在我的 AJS 控制器中执行这两行
User.username = $scope.usernameVar;
and User.password = $scope.passwordVar;
和
User.password = $scope.passwordVar;
attach the usernameVar and passwordVar values to the req
object on my server for the route '/login'
?将 usernameVar 和 passwordVar 值附加到我服务器
req
由'/login'
的req
对象?
If you have a form with action to post to your path /login
, and have input names labeled after your username
and password
, the submit button will pass the values along to your passport code.如果您有一个带有操作的表单可以发布到您的路径
/login
,并且在您的username
和password
之后标记了输入名称,则提交按钮会将值传递给您的护照代码。
