将对象数组发布到sails会导致'TypeError:无法将对象转换为原始值'

Question

在我的html页面中,我将此帖子发送到我的sails服务器,但由于req.param()函数没有返回任何有意义的答案,我无法访问控制器中的数据.

这是网页代码

$.post("http://myserver.local/calendar/batch",
            {"batch":[
                {
                    "start_date" : "2014-06-27T09:00:00Z",
                    "title" : "abc",
                    "attendees" : [
                        "Fred Bloggs",
                        "Jimmy Jones",
                        "The Queen"
                    ],
                    "event_id" : "123",
                    "location" : "Horsham, United Kingdom",
                    "end_date" : "2014-06-27T10:30:00Z"
                },
                {
                    "start_date" : "2014-06-27T09:00:00Z",
                    "title" : "another",
                    "attendees" : [
                        "Fred Bloggs",
                        "Jimmy Jones",
                        "The Queen"
                    ],
                    "event_id" : "def",
                    "location" : "Horsham, United Kingdom",
                    "end_date" : "2014-06-27T10:30:00Z"
                }
            ]},
    function (data) {
        console.log("success");
    }
    ).fail(function(res){
        console.log("Error: " + res.getResponseHeader("error"));
    });

这是控制器

module.exports = {
  batch: function (req, res, next){
    console.log("batch called");
    console.log("req.body" + req.body);
    console.log("req.param()" + req.param());
    res.send("ok");
  },

  _config: {}
};

我尝试过使用req.body,但似乎不包含任何内容.这是我在输出中得到的

batch called
req.body=[object Object]
TypeError: Cannot convert object to primitive value
    at Array.toString (native)

Answer 1

module.exports = {
 batch: function (req, res, next){
  console.log("batch called");
  console.log(req.body);
  console.log(req.param("batch"));
  res.send("ok");
},

_config: {}
};

如果使用console.log("foo" + object)nodejs将尝试将obeject转换为字符串.简单地做console.log(object)
