我使用passport.js passport-facebook-token来保护我的API构建与Strongloop的Loopback Framework.
为什么护照在成功反序列化后再次序列化反序列化用户?每个请求都会调用passport.authenticate方法!我究竟做错了什么?
这是节点的日志:
deserializeUser, id: XXXXXXXXXXXXXXXX
User found.
serializeUser, id: XXXXXXXXXXXXXXXX
GET /api/events?access_token=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX 304 182ms
这是js代码:
passport.use(new FacebookTokenStrategy({
clientID: XXXXXXXXXXXXXXXX,
clientSecret: 'XXXXXXXXXXXXXXXXXXXXXXXXXXXX'
},
function(accessToken, refreshToken, profile, done) {
//check user table for anyone with a facebook ID of profile.id
User.findOne({
'facebookId': profile.id
}, function(err, user) {
if (err) {
return done(err);
}
if (user) {
console.log("User found.");
return done(err, user);
} else {
console.log("User not found.");
User.create({
email: profile.emails[0].value,
facebookId: profile.id,
password: 'secret'
}, function(err, user) {
console.log(user.id);
console.log(user.email);
console.log(user.facebookId);
console.log("User created");
return done(err, user);
});
}
});
}));
passport.serializeUser(function(user, done) {
console.log('serializeUser, id: ' + user.facebookId);
done(null, user.facebookId);
});
passport.deserializeUser(function(id, done) {
console.log('deserializeUser, id: ' + id);
User.findOne({
'facebookId': id
}, function(err, user) {
if (!err) {
done(null, user);
} else {
done(err, user);
}
});
});
解决方法:
关于为什么在每个请求上调用passport.authenticate的问题,这是因为您可能在任何路由逻辑发生之前将其定义为中间件.
如果您的应用上有私人和公共部分,则可以执行以下操作:
// Define a specific that will handle authentication logic
app.get("/auth", passport.authenticate('facebook-token',function(){...});
// Public sections which do not require authentication
app.get("/public1",...);
app.post("/public2",...);
// Private sections which do require authentication
app.get("/private1", function(req,res,next){
if (req.isAuthenticated()){ // Check if user is authenticated
// do things...
}else{ // Wow, this guy is not authenticated. Kick him out of here !
res.redirect("/auth");
}
});
现在,如果你有多个私有部分,你可能会觉得为每个私有部分做同样的事情有点不可思议.
您可以定义一个自定义函数来检查用户是否经过身份验证,并允许请求继续进行.
就像是
function isThisGuyAuthenticated(req,res,next){
if (req.isAuthenticated()){
return next(); // Ok this guy is clean, please go on !
}else{
res.redirect("/auth"); // This guy is shady, please authenticate !
}
}
并使用它像:
app.get("/private1",isThisGuyAuthenticated, doCrazySecretStuff); // doCrazySecretStuff will not be called if the user is not authenticated
app.get("/private2", isThisGuyAuthenticated, getCocaColaRecipe);
app.get("/private3", isThisGuyAuthenticated, flyToMars);
app.get("/public", showInfo); // showInfo will be called whether the user is authenticated or not
现在,如果您的应用程序只有私有部分,您可以通过将其定义为中间件来避免重复调用isThisGuyAuthenticated(但不能将passport.authenticate本身定义为中间件!);
// Endpoint that will be hit is the user is redirected to /auth
// BEWARE it needs to be above the middleware, otherwise you'll end up with an infinite redirection loop
app.get("/auth", passport.authenticate('facebook-token',function(){...});
// Middleware that will be called on every request
app.use(isThisGuyAuthenticated);
// You app's endpoints
app.get("/private1", doCrazySecretStuff); // doCrazySecretStuff will not be called if the user is not authenticated
app.get("/private2", getCocaColaRecipe);
app.get("/private3", flyToMars);
明白了吗 ?
编辑:我错误地将中间件放在“/ auth”端点之前.确保它放在后面
