通过AJAX POST JSON数据发送一个空数组 [英] POST json data via ajax sends an empty array

问题描述

我尝试后通过AJAX的数据，这是我的信息：

  VAR jsondata =
                {地址 ： [
                {ID：ADDID的StreetAddress：的StreetAddress，城市：城市，状态：国家拉链code：拉链code，纬度：纬度}，
            ]
            };

    VAR jsontosend = JSON.stringify（jsondata，空，2）;
 

AJAX功能：

  $。阿贾克斯（{
                键入：POST，
                网址：process.php
                的contentType：应用/ JSON的;字符集= UTF-8，
                数据类型：JSON，
                数据：jsontosend，
                成功：函数（MSG）{
                   警报（味精）;
                          }
             }）;

            返回false;

            警报（数据派）;
 

}

在PHP结束，当我的print_r（$ _ POST），它只是说

 阵列（0）{
    }
 

我报警（jsontosend）及其使用后评判出我的一切完美，以及在萤火虫，它显示了所有在一个完美的清洁方式发送的PARAMS。

传递任何数据的唯一方法是，如果我用GET方法。

任何意见大大AP preciated！

编辑：从萤火添加POST数据。 这是什么正从警报功能提醒：

  {地址：[{ID：1473294的StreetAddress：3784霍华德大道，城市：华盛顿，状态：DC ，拉链code：20895，纬度：39.027820587}]}
 

这是什么Firebug是它呈现什么用POST方法时传递：

  myData=%7B%0A++++%22address%22%3A+%5B%0A++++++++%7B%0A++++++++++++%22id%22%3A+76076%2C%0A++++++++++++%22streetaddress%22%3A+%223784+Howard+Ave%22%2C%0A++++++++++++%22city%22%3A+%22Washington+DC%22%2C%0A++++++++++++%22state%22%3A+%22DC%22%2C%0A++++++++++++%22zip$c$c%22%3A+20895%2C%0A++++++++++++%22latitude%22%3A+39.027820587%0A++++++++%7D%0A++++%5D%0A%7D
 

这是为$ _ POST的var_dump响应：

 阵列（0）{
 

}

这是$ _ POST一个的var_dump ['myData的']

  NULL
 

解决方案

我怀疑你使用的contentType属性的方式。尝试取出的contentType。默认的内容类型是 应用程序/ x-WWW的形式urlen codeD（ http://api.jquery.com/ jQuery.ajax / ）。

此外，使用类似于{MYDATA：jsontosend}。为您的数据属性

  $。阿贾克斯（{
            键入：POST，
            网址：process.php
            //的contentType：应用/ JSON的;字符集= UTF-8，
            数据类型：JSON，
            数据：{MYDATA：jsontosend}，
            成功：函数（MSG）{
               警报（味精）;
                      }
         }）;
 

I'm trying to post data via ajax, this is my info:

    var jsondata =
                {"address" : [
                { "id": addid, "streetaddress": streetaddress, "city": city, "state": state,  "zipcode": zipcode, "latitude": latitude},
            ]   
            };  

    var jsontosend = JSON.stringify(jsondata, null, 2);

ajax function:

    $.ajax({
                type: "POST",
                url: "process.php",
                contentType: "application/json; charset=utf-8",
                dataType: "JSON",
                data: jsontosend,
                success: function(msg){
                   alert(msg);
                          }
             });

            return false;

            alert('Data sent');

}

on the php end, when i print_r($_POST) it just says

    array(0) {
    }

I'm alerting (jsontosend) and its showing me everything perfectly, as well as in firebug using post mothod, its showing all the params sent in a perfect clean manner.

The only way it passes any data is if I use GET method.

Any advice is greatly appreciated!

EDIT: adding POST data from firebug. this is whats being alerted from the alert function:

    {"address":[{"id":1473294,"streetaddress":"3784 Howard Ave","city":"Washington DC","state":"DC","zipcode":20895,"latitude":39.027820587}]}

this is what firebug is showing as whats being passed when using POST method:

    myData=%7B%0A++++%22address%22%3A+%5B%0A++++++++%7B%0A++++++++++++%22id%22%3A+76076%2C%0A++++++++++++%22streetaddress%22%3A+%223784+Howard+Ave%22%2C%0A++++++++++++%22city%22%3A+%22Washington+DC%22%2C%0A++++++++++++%22state%22%3A+%22DC%22%2C%0A++++++++++++%22zipcode%22%3A+20895%2C%0A++++++++++++%22latitude%22%3A+39.027820587%0A++++++++%7D%0A++++%5D%0A%7D

and this is the response for var_dump of $_POST:

    array(0) {

}

this is a var_dump of $_POST['myData']

    NULL

解决方案

I'm skeptical of the way you're using the contentType property. Try taking out contentType. The default content type is application/x-www-form-urlencoded (http://api.jquery.com/jQuery.ajax/).

Also, use something like {mydata: jsontosend} for your data property.

$.ajax({
            type: "POST",
            url: "process.php",
            //contentType: "application/json; charset=utf-8",
            dataType: "JSON",
            data: {mydata: jsontosend},
            success: function(msg){
               alert(msg);
                      }
         });
