Posting object array to sails causes 'TypeError: Cannot convert object to primitive value'

问题:

In my html page i am sending this post to my sails server but I cannot get to the data in my controller as the req.param() function does not return any meaningful answer.

Here is the web page code

$.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"));     }); 

Here is the controller

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: {} }; 

I have tried using req.body but that does not seem to contain any content. This is what i get in the output

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

回答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: {} }; 

If you use console.log("foo" + object) nodejs will try to convert the obeject into a string. Simply do console.log(object)
