我想从 jQuery 向远程服务器发出 POST 请求。当我写这样的代码时

$.ajax({
             type: 'POST',
                url: 'http://mysite:8080/orderService/order/send',
                crossDomain: true,
                data: JSON.stringify(orderSendRequest),
                dataType: 'json',
                success: function(responseData, textStatus, jqXHR) {
                    var value = responseData.someKey;
                },
                error: function (responseData, textStatus, errorThrown) {
                    alert('POST failed.');
                }
        });

一切正常,但我希望 ContextType 为 application/json,当我将此行添加到代码中时,请求不起作用,并且出现以下错误:

XMLHttpRequest cannot load http://mysite:8080/orderService/order/send. Origin null is not allowed by Access-Control-Allow-Origin.

$.ajax({
             type: 'POST',
                url: 'http://mysite:8080/orderService/order/send',
                crossDomain: true,
                data: JSON.stringify(orderSendRequest),
                dataType: 'json',
                contentType : 'application/json; charset=utf-8',
                success: function(responseData, textStatus, jqXHR) {
                    var value = responseData.someKey;
                },
                error: function (responseData, textStatus, errorThrown) {
                    alert('POST failed.');
                }
        });

我不相信 json 支持跨域。改为使用 jsonp 数据类型进行研究。
