小编Pau*_*ulE的帖子

我正在尝试发送一个帖子参数.到request.php,但它返回后PARAM.是空的.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
$.ajax({
    url: "request.php",
    type: "POST",
    data: "{key:'123', action:'getorders'}",
    contentType: "multipart/form-data",
    complete: alert("complete"),
    success: function(data) {
        alert(data);
    },
    error: alert("error")
});
