Question

我正在尝试使用Twitter REST API GET关注者/ ids并使用Mongo集合插入方法将其保存到Mongo

/server/server.js中的代码：

boost::variant

服务器控制台出错：

Meteor.startup(function () {
    // code to run on server at startup

    TwitterFollowersIDsCollecions = new Mongo.Collection("twitterFollowersIDs");

    var Twit = Meteor.npmRequire('twit');
    var T = new Twit({
        consumer_key:         '###',
        consumer_secret:      '###',
        access_token:         '###',
        access_token_secret:  '###'
    });

    var getTwitterFollowersIDsAsync = function (screenname, cb) {
        T.get('followers/ids', { screen_name: screenname }, function (err, data, response) {
                console.log(data);
                var vids = data.ids;
                for(var i in vids) {
                    TwitterFollowersIDsCollecions.insert({
                        twitterFollowerID:vids[i]
                    });
                }
            }
        );
    };

    Meteor.methods({
        getTwitterFollowersIDsCollectionsClient : function (screenname){
            var getTwitterFollowersIDsNow = Meteor.wrapAsync(getTwitterFollowersIDsAsync);
            var result = getTwitterFollowersIDsNow('meteorjs');
            console.log(result);
            return result;
        }
    });

});

目标是将Twitter粉丝保存到Mongo集合中。

Meteor v.1.1.0.2

流星套餐：

meteor-platform
autopublish
不安全
差异：硫化
accounts-twitter
accounts-ui
meteorhacks：npm
npm-container

通过

Error: Meteor code must always run within a Fiber. 
Try wrapping callbacks that you pass to non-Meteor libraries with Meteor.bindEnvironment.

：meteorhacks:npm在meteor内部使用npm模块（在packages.json中添加）

**更新第二次尝试**

"twit": "1.1.20"

然后我从浏览器控制台调用以下代码：

Meteor.startup(function () {

  // code to run on server at startup

  TwitterFollowersIDsCollecions = new Mongo.Collection("twitterFollowersIDs");

  var Twit = Meteor.npmRequire('twit');

  var T = new Twit({
        consumer_key:         '###',
        consumer_secret:      '###',
        access_token:         '###',
        access_token_secret:  '###'
    });

  Meteor.methods({

    // this is the server method called from the client

    getTwitterFollowersIDsCollectionsClient : function (){
      setTimeout(function(){
        Meteor.call('getTwitterFollowersIDsNow', 'meteorjs');
      },10);
      return;
    },

    getTwitterFollowersIDsNow : function (screenname) {
      T.get('followers/ids', { screen_name: screenname }, function (err, data, response) {
        console.log(data);
      });
    }

  });

});

服务器崩溃并出现同样的错误：

Meteor.call('getTwitterFollowersIDsCollectionsClient');

UDPATE：

Error: Meteor code must always run within a Fiber. Try wrapping callbacks     that you pass to non-Meteor libraries with Meteor.bindEnvironment.

将Meteor.bindEnvironment添加到T.get回调方法。此代码有效，我能够将关注者ID保存到mongo集合

很高兴你得到它的工作，但我玩这个和Meteor提供另一个，超级简单的方法：wrapAsync。至少，一旦我弄清楚它就很容易了！这是我用的服务器代码 -

var T = new TwitMaker({
    consumer_key:         '...'
  , consumer_secret:      '...'
  , access_token:         '...'
  , access_token_secret:  '...'
})

var wrapGet = Meteor.wrapAsync(T.get, T);

Meteor.methods({

  getTwitImg: function(target) {
    data = wrapGet('users/show', {screen_name: target});
    if (data) {
      img_url = data['profile_image_url'];
      US.update({twitter: target}, {$set: {'targetImg': img_url}});
      return img_url;
    }
  }

});

您的代码有点令人困惑。您似乎正在尝试执行Web服务调用异步，但仍然会立即返回结果（这不会起作用）。

首先，你可能不需要包装该函数来获取异步块中的追随者。

如果您希望服务器方法在调用后立即向客户端返回某些内容，我会使用Meteor.setTimeout（请参阅What's the point of Meteor.setTimeout() vs just setTimeout()?）块并调用其他方法来执行取：

Meteor.methods({

    // this is the server method called from the client
    getTwitterFollowersIDsCollectionsClient : function (screenname){
        Meteor.setTimeout(function() { 
          Meteor.call('getTwitterFollowersIDsNow', 'meteorjs');
        }, 10);
        return;
    },

    getTwitterFollowersIDsNow : function (screenname) {
        T.get('followers/ids', { screen_name: screenname }, function (err, data, response) {
            console.log(data);
            var vids = data.ids;
            for(var i in vids) {
                TwitterFollowersIDsCollecions.insert({
                    twitterFollowerID:vids[i]
                });
            }
        }
    }
});

理想情况下，您可以使用模板助手从您的收藏集中检索您的关注者。由于这些助手是被动的，你可以从客户端调用服务器方法，让Meteor的反应性解决你通过帮助器返回追随者的问题（在数据更改时重新执行/重新渲染模板））。

尝试致电：

 point.sqrmPrice  <- ggplot(overview.df, aes(x = areaSize, y = sqrmPrice)) + 
      geom_line() +
      geom_point() + 
      scale_y_continuous(breaks = c(seq(min(overview.df$sqrmPrice), max(overview.df$sqrmPrice), by = 10000) )) + 
      theme_bw()

来自api回调

var wrappedInsert = Meteor.bindEnvironment(function(tweet) {
TweetsCollection.insert(tweet);},
"Failed to insert tweet into Posts collection.");

Meteor wrapasync保存对Mongo集合的Twitter REST响应，给出错误＆＃34;错误：流星代码必须始终在光纤内运行。＆＃34;
