Jquery ajax Post +跨​​域[重复]

Question

可能重复：
Access Control Allow Origin not allowed by

我在尝试使用 jquery 发帖时遇到问题：

             function SetUserAnswer(reponse) {
    $.ajax({
        type: "POST",
        url: "@SettingManager.GetValue("WS_Sondage_Adress").Value" + "SetUserAnswer",
        data: JSON.stringify({ deviceId: $("#Guid").attr("value"),
            pollId:  $("#PollId").attr("value"),
            answerId: reponse,
            parameters: ""
        }),
       dataType: "json",
       crossDomain: true,
      contentType: "application/json; charset=utf-8"
    }).done(function () {
        alert("OK !");
    }).fail(function () {
        alert("KO :(");
    });

}

但 Firefox 发送“选项”而不是“发布”

我在做跨域发帖时只有这个问题？

Answer 1

也将数据类型从 json 更改为 jsonp，我在您的回复中看不到后续标题

Access-Control-Allow-Origin *
