我尝试在JSFiddle上模拟类似的情况,尽管我已经从后端准备了数据

获取/发送数据 – >后端方面：

//push data to Redis
var messages= JSON.stringify(
    [
        {
            "name": "Msg1","desc": "desc Msg1"
        },{
            "name": "Msg2","desc": "desc Msg2"
        },{
            "name": "Msg3","desc": "desc Msg3"
        },{
            "name": "Msg4","desc": "desc Msg4"
        }
    ]);
    redisClient.lpush('list',messages,function (err,response) {
        console.log(response);
    });

//get from redis and send to frontend
app.get('/messages',function(req,res){
    // Query your redis dataset here
    redisClient.lrange('list',-1,function(err,messages) {
        console.log(messages);
       // Handle errors if they occur
       if(err) res.status(500).end();
       // You could send a string
       res.send(messages);
       // or json
       // res.json({ data: reply.toString() });
    });
});

获取数据 – >前端(角度)

angular.module('app')
    .controller('MainCtrl',['$scope','$http',function ($scope,$http) {
        'use strict';

        getFromServer();
        function getFromServer(){
          $http.get('/messages')
               .success(function(res){
                   $scope.messages= res;
                   console.log(res);
               });
        }
    }])

带有ng-repeat指令的HTML部分：

<div ng-app="app" ng-controller="MainCtrl" class="list-group">
    <div class="list-group-item" ng-repeat="item in messages">
        <h4 class="list-group-item-heading">{{item.name}}</h4>
        <p class="list-group-item-text">{{item.desc}}</p>
    <div>
</div>

谁会知道问题是什么？
