我使用Instagram-passport登录我的应用程序。用户登录后如何获取用户名和访问令牌?我无法访问中间件部分中的“配置文件”。
//serialize user in the session
passport.serializeUser(function (user, done) {
done(null, user);
});
//deserialize user in the session
passport.deserializeUser(function (id, done) {
User.findById(id, function (err, user) {
done(err, user);
});
});
//callback after successfull login of instagram
exports.callback = function (req, res) {
// Successful authentication, redirect home.
console.log('calling');
var code = req.query.code;
//console.log('accessToken:' + accessToken);
console.log(req.session)
getOption(code, function (option) {
//console.log('option from getOption callback ' + util.inspect(option, false, null));
request(option, function (error, response, body) {
console.log('response inside request: ' + util.inspect(body, false, null));
fs.writeFile("test", JSON.stringify(error), function (err) {
if (err) {
console.log(err);
} else {
console.log("The file was saved!");
}
});
res.writeHead(200, {
'Content-Type': 'text/json'
});
//res.end(response);
});
});
// Successful authentication, redirect home
}
//function to get the option for the first parameter in the request function
function getOption(code, callback) {
console.log('code from getOption ' + code)
var options = {
url: 'https://api.instagram.com/oauth/access_token',
headers: {
'client_id': 'client-id',
'client_secret': 'client-secret`enter code here`',
'grant_type': 'authorization_code',
'redirect_uri': '/instagramcallback',
'code': code
}
};
callback(options);
}
//middleware
passport.use(new InstagramStrategy({
clientID: 'my client-id',
clientSecret: 'my client secret',
callbackURL: "/instagramcallback"
},
function (accessToken, refreshToken, profile, done) {
// asynchronous verification, for effect...
global.accessToken=accessToken;
// To keep the example simple, the user's Instagram profile is returned to
// represent the logged-in user. In a typical application, you would want
// to associate the Instagram account with a user record in your database,
// and return that user instead.
console.log('client profile:'+profile);
return done(null, profile);
}
));

var express = require('express');
var api = require('instagram-node').instagram();
var app = express();
app.configure(function() {
// The usual...
});
api.use({
client_id: YOUR_CLIENT_ID,
client_secret: YOUR_CLIENT_SECRET
});
var redirect_uri = 'http://yoursite.com/handleauth';
exports.authorize_user = function(req, res) {
res.redirect(api.get_authorization_url(redirect_uri, { scope: ['likes'], state: 'a state' }));
};
exports.handleauth = function(req, res) {
api.authorize_user(req.query.code, redirect_uri, function(err, result) {
if (err) {
console.log(err.body);
res.send("Didn't work");
} else {
console.log('Yay! Access token is ' + result.access_token);
res.send('You made it!!');
}
});
};
// This is where you would initially send users to authorize
app.get('/authorize_user', exports.authorize_user);
// This is your redirect URI
app.get('/handleauth', exports.handleauth);
http.createServer(app).listen(app.get('port'), function(){
console.log("Express server listening on port " + app.get('port'));
});
