Question

我是Express.js，Node.js和Passport.js的新手。我正在尝试开发一个应用程序，其中用户使用他们的Twitter帐户登录，然后他们可以看到他们的提及（其他Twitter用户已经提到登录用户的Twitter用户名的推文）。我遇到了Passport.js，并且我已成功使用它，允许用户使用他们的Twitter帐户登录。

但是，我不知道如何格式化Twitter提及的服务器端HTTP GET请求。我在https://dev.twitter.com/docs/api/1/get/statuses/mentions多次审查了Twitter API，但由于我不熟悉Node / Express / Passport平台，我不知道如何执行此请求服务器端以返回JSON格式的提及。该应用程序设置为只读，因为它只需要能够与相关用户一起查看相关推文。

前端基于EJS。以下是我可能相关的代码。非常感谢你的帮助。

/app.js

/**

var express = require('express')
  , passport = require('passport')
  , http = require('http')
  , util = require('util')
  , path = require('path')
  , TwitterStrategy = require('passport-twitter').Strategy;

var TWITTER_CONSUMER_KEY = "theConsumerKeyForMyApp";
var TWITTER_CONSUMER_SECRET = "theConsumerSecretForMyApp";

var users = [];

// Passport session setup.
passport.serializeUser(function(user, done) {
  done(null, user.id);
});

passport.deserializeUser(function(id, done) {
  var user = users[id];
  done(null, user);
});


// Use the TwitterStrategy within Passport.
passport.use(new TwitterStrategy({
    consumerKey: TWITTER_CONSUMER_KEY,
    consumerSecret: TWITTER_CONSUMER_SECRET,
    callbackURL: "http://127.0.0.1:3000/auth/twitter/callback"

    //console.log(token);
    //console.log(tokenSecret);

    // asynchronous verification, for effect...
    process.nextTick(function () {
      var user = users[profile.id] || (users[profile.id] = profile);
      done(null, user);
    });

安装模块： $ npm install oauth

然后使用此代码创建GET请求（根据需要替换变量）。

var oauth = new OAuth.OAuth(
  'https://api.twitter.com/oauth/request_token',
  'https://api.twitter.com/oauth/access_token',
  'your application consumer key',
  'your application secret',
  '1.0A',
  null,
  'HMAC-SHA1'
);
oauth.get(
  'https://api.twitter.com/1.1/trends/place.json?id=23424977',
  'your user toke for this app', //test user token
  'your user secret for this app', //test user secret            
  function (e, data, res){
    if (e) console.error(e);        
    console.log(require('util').inspect(data));
    done();      
  });

我创造了类似于你想要做的事情。由于您已成功登录，我假设您能够获得访问令牌和秘密。完成后，使用mtwitter之类的外部库。我这样打电话（编辑我从我的数据库中获取令牌的部分）：

app.get('/twitter/userMentions', function (req, res) {
    var twit = new mtwitter({
        consumer_key: consumerKey,
        consumer_secret: consumerSecret,
        access_token_key: token,
        access_token_secret: secret
    });

    twit.get("/statuses/mentions_timeline", { "include_entities": false },
        function (err, data) {
            if (err) {
                res.write(err.toString());
            }
            else res.write(JSON.stringify(data));

            res.end('\n');
        });
     }

我认为您正在寻找请求节点模块!!
