javascript - 服务器端 AJAX post 为空(PHP)

Question

我正在使用 jQuery ajax 向 PHP Controller 发出 AJAX 请求，但是当尝试使用 PHP 获取发布的数据时，$_POST 为空。下面是实际的功能:

function GetSeriesForManufacturer(manuf) {
    selectedmanufacturer = manuf;
    //Make an AJax Call For Getting Series Of Manufacturer
    var series = null;
    $.ajax({
        type: "POST",
        url: url,
        data: "{manufacturer:'" + selectedmanufacturer + "'}",
        contentType: "application/json", //; charset=utf-8",
        dataType: "json",
        cache: false,
        async: false,
        success: function (response) {
            //remove loading gif
            $(".loading").hide();
            //Append Data
            AppendSeries($.parseJSON(response.text), selectedmanufacturer);
            //Custom Scrollbar Call
            $('.MatchingSeries ul').mCustomScrollbar();                        
        },
        error: function (XMLHttpRequest, textStatus, errorThrown) {  }
    });                         
}

提前致谢!

Answer 1

首先，您不需要对数据进行字符串化。只需发送对象文字即可。

data: {manufacturer: selectedmanufacturer},

第二，你不需要这一行:

contentType: "application/json",
