jQuery AJAX JSONP 错误“意外的令牌”

我正在尝试跨域JSONP在 Chrome 中打电话，但我总是回复“未捕获的语法错误：意外的标记：”我尝试过：更改响应内容类型、设置 xhr 标头、JSON.stringify，几乎是此处提供的大多数解决方案，但到目前为止没有任何效果:-(

 $.ajax({
                type: "POST",
                url: "https://www.virustotal.com/vtapi/v2/url/report",
                crossDomain: true,
                contentType: "application/json; charset=UTF-8",
                dataType: 'jsonp',
                data: {
                    apikey: "*",
                    resource: "http://www.1001freefonts.com/font/BaroqueScript.zip"
                },
                jsonp: false,
                jsonpCallback: receive,
                success: function (data, textStatus, jqXHR) {
                    console.log("Data retrieved: " + data);
                }
            }).done(function () {
                console.log('I think we are done here');
            })
        .error(function (e) {
            console.log(arguments);
            console.log('something went funny here');
        })
        .complete(function (xhr, status) {

            console.log("complete");
        if (status === 'error' || !xhr.responseText) {
            console.log('error');
        }
        else {
            console.log("data found:" + xhr.responseText);
            //...
        }
    });
    });

    function receive(saveData) {
        if (saveData == null) {
            console.log("DATA IS UNDEFINED!");  // displays every time
        }
        console.log("Success is " + saveData);  // 'Success is undefined'
    }

在调试器中我可以看到响应

我已经验证过http://jsonlint.com/ http://jsonlint.com/它表明它是一个有效的 JSON。

这是响应标头

cache-control:no-cache
content-encoding:gzip
content-length:695
content-type:application/json

有人有什么想法/建议吗？

经过彻底的测试，很明显，当 ajax 期望返回 JSONP 时，不可能捕获 JSON 对象结果（由于跨域限制）。即使响应状态 = 200。

我一直在使用 jQuery AJAX 调用进行测试，试图查看是否仍然可以捕获结果 - 尽管浏览器抛出解析错误 - 但似乎这是不可能的。看起来响应文本是在 JS 工作完成后到达标头的。

正如 @Florian F. @Likwid_T @Christoph 上面所建议的，肯定需要服务器端脚本才能使其正常工作。其他开发人员似乎热衷于使用用 C# 编写的代理作为解决方案。
