我刚刚开始学习Node和Express(MEAN堆栈),我想知道,PassportJS可以用来查询Twitter API v1.1,还是仅用于身份验证?
我已经构建了以下代码,但是我没有得到任何可取的(应用程序崩溃):
我的控制器:
/**
* Module dependencies.
*/
var mongoose = require('mongoose'),
async = require('async'),
passport = require('passport'),
TwitterStrategy = require('passport-twitter').Strategy,
_ = require('underscore');
exports.auth = function(req, res, passport) {
passport.use(new TwitterStrategy({
consumerKey: '7rTisA540o3BkQPRItqog',
consumerSecret: 'u5f4xShik2GSypDu7pFuXpRlf23nZdS1CeZCMSXE',
callbackURL: "http://localhost:3000/auth/twitter/callback"
},
function(token, tokenSecret, profile, done) {
console.log(token, tokenSecret, profile, done);
}
));
};
路线:
// Twitter API
app.get('/twitter', twitter.auth);
当我点击Localhost:3000 / twitter时,我最终收到以下消息:
TypeError: Object function callbacks(err) {
var fn = route.callbacks[i++];
try {
if ('route' == err) {
nextRoute();
} else if (err && fn) {
if (fn.length < 4) return callbacks(err);
fn(err, req, res, callbacks);
} else if (fn) {
if (fn.length < 4) return fn(req, res, callbacks);
callbacks();
} else {
nextRoute(err);
}
} catch (err) {
callbacks(err);
}
} has no method 'use'

我对此完全陌生,我希望获得身份验证令牌然后从那里我可以查询API,但是,我无法通过第一步。我在代码中做错了什么,或者我是否错误地使用了Passport库?
答案 0 :(得分:0)
看起来在exports.auth
函数内部,passport
参数不是您所期望的。您已经在应用程序中删除了大部分代码,因此不清楚您在其他地方使用该函数的方式,但似乎参数(护照库本身)未正确传递。
您可以单步执行代码并检查该参数的值是使用调试器并查找问题。有关详细信息,请参阅此问题:https://stackoverflow.com/a/3944507/1801
