从我的 javascript 文件中，我正在调用一个间隔函数，这是代码

setInterval(function() {
  $.getJSON('/home/trackUnreadMsgs', function(result) {
    $.each(result, function(i, field) {
      var temp = "#messby" + result[i].from;
      $(temp).css("background", "grey");
      //alert('hi');

    });
  });
}, 1000),

这是被调用的函数， php 中的 trackUnreadMsgs。

public function trackUnreadMsgs() {
  $data['userData'] = $this - > session - > userdata('userData');
  $user_id = $data['userData'][0]['id'];

  $count_unread_msgs = $this - > data - > myquery("SELECT * FROM inbox WHERE `to`=".$user_id.
    " AND status='unread'");

  $count_unread_msgs = json_encode($count_unread_msgs);
  print_r($count_unread_msgs);
}

显然一切都在浏览器（Chrome）上运行良好，但这是控制台正在打印的内容：

我想知道，我做错了什么，为什么我会收到这个日志以及如何解决这个问题。我在 localhost Wamp 服务器上运行它。

您在 AJAX 请求中设置了错误的路由。正确的路径是

$.getJSON('/innov/index.php/home/trackUnreadMsgs', function(result) { ... });
