php – 在CodeIgniter中检索JSON POST数据

我一直在尝试从我的PHP 文件中检索 JSON数据.它让我很难.这是我的代码

我的视图中的代码：

var productDetails = {'id':ISBNNumber,'qty':finalqty,'price':finalprice,'name':bookTitle};

        var base_url = '<?PHP echo site_url() ?>';
        $.ajax({
            url: "<?PHP echo base_url() ?>index.PHP/user/Add_to_cart/addProductsToCart",type: 'POST',data:productDetails,dataType:'JSON',});

试图在我的控制器中检索：

echo $this->input->post("productDetails");

输出什么都没有.

这是我的标题：

我在Developer工具中可以看到的响应：

Array
(
    [id] => 234
    [qty] => 1
    [price] => 0.00
    [name] => dasdadsd2q3e!@!@@
)

但在浏览器中,输出什么都没有.我现在试图解决它超过4个小时但是徒劳无功.

print_r($_POST); // outputs nothing
echo $data = file_get_contents('PHP://input'); //outputs nothing
echo $id    = $this->input->post('productDetails');// outputs nothing

我的观点代码：

<script>
    $('#addtoCart').on('click',function(event){
        event.preventDefault();
        $(this).attr('disabled',"disabled");
        finalprice = $.trim($('#price').val());
        finalqty = $.trim($('#quantity').val());

        var productDetails = JSON.stringify({'id':ISBNNumber,'name':bookTitle});

        var base_url = '<?PHP echo site_url() ?>';
        // console.log($);
        $.ajax({
            url: "<?PHP echo base_url() ?>index.PHP/user/Add_to_cart/addProductsToCart",contentType: "application/json; charset=utf-8",dataType:'html',});


    });
</script>

控制器代码：

function addProductsToCart(){
        var_dump(json_decode(file_get_contents("PHP://input")));
        print_r($_POST);
        // $data = json_decode($_POST["productDetails"]);
        // var_dump($data);
        // echo $data = file_get_contents('PHP://input');
// print_r(json_decode($data));
        // $id    = $this->input->post('id');
        // $qty   = $this

    }

我用于CI中的Ajax调用的一般方法：

JS：

post_array =
{
    "myvar" : "value1","myvar2": "value2"
} 

$.post(baseUrl + "/AjaxController/my_function",post_array,function(data)
    {
        var res = jQuery.parseJSON(data);
        alert(res.property);
    }

控制器：

public function my_function()
{
    $myvar = $this->input->post('myvar');
    $myvar2 = $this->input->post('myvar2'); 

    //Stuff

    echo json_encode($myobject);
}
