Question

我正在使用express.js，mongoose，jquery和socket.io

我正在尝试传递对象＆＃34; allFightScores＆＃34;客户端上的套接字。这是我在routes / index.js中从mongoose请求信息的地方：

var models = require('../models/index.js');
var passport = require('passport');
var crawl = require('../crawler.js');
var flash = require('connect-flash');
var express = require('express');
var app = express();
var server = require('http').createServer(app);
var io = require('socket.io').listen(server);

exports.submit_scores = function(req, res){

  var scored_fight = new models.UserScore({
    "f1": req.body.f1,
    "f2": req.body.f2,
    "f1_roundScores": req.body.f1_roundScores,
    "f2_roundScores": req.body.f2_roundScores,
    "f1_score": req.body.f1_score,
    "f2_score": req.body.f2_score,
    "user_email": req.body.user_email
  });

  models.UserScore.find({
    "f1": scored_fight.f1,
    "f2": scored_fight.f2,
    "f1_score": scored_fight.f1_score,
    "f2_score": scored_fight.f2_score,
    "user_email": scored_fight.user_email
  }, function(err, data){
    if (data.length === 0){
      scored_fight.save(function(err, user_fight){
        if (err) {
          return "error";
        }
        else {
          models.UserScore.find({"f1": user_fight.f1, "f2": user_fight.f2}, function(err, allFightScores){
            console.log("from index-routes " +allFightScores);
            io.sockets.emit('show scores', allFightScores)
          })
        }
      })
      //put a callback on the user_scored_fight data, also emit that data with the average scores;
      res.json(scored_fight);
    }
    else if (data[0].f1 === scored_fight.f1 && data[0].f2 === scored_fight.f2 && data[0].user_email === scored_fight.user_email) {
      res.json(200);
      console.log("data already judged.");
    }
  })
}

以下是我在我的客户端上捕获数据的位置（public / javascripts / script.js）：

jQuery(function($){
  socket = io.connect();

  var $group_f1_score = $('#gf1_score');
  var $group_f2_score = $('#gf2_score');

  socket.on('show scores', function(mongooseData){
    console.log("mongooseData from scripts " + mongooseData)

    $group_f1_score.empty();
    $group_f2_score.empty();

  //sum fighter scores for all user submissions
    var f1_sumScore = 0;
    var f2_sumScore = 0;
    for (var i = 0; i < mongooseData.length; i++){
      f1_sumScore += mongooseData[i].f1_score;
      f2_sumScore += mongooseData[i].f2_score;
    }
    //get the simple average
    var f1_avgScore = f1_sumScore/mongooseData.length;
    var f2_avgScore = f2_sumScore/mongooseData.length;

    $group_f1_score.append(f1_avgScore);
    $group_f2_score.append(f2_avgScore);
  })
})

我不确定为什么数据不会向我的客户端发出，而且我没有想法。我是否正确查询数据并将其传递给回调？

我无法在您的代码中看到这一点：

server.listen(port);

使用socket.io在客户端上发出错误信息
