我正在尝试调用部署在 IIS 上并启用基本身份验证的 WCF 服务，从 j 查询如下。

$(document).ready(function () {
                    $.ajax({
                        type: "GET",
                        dataType: "jsonp",
                        contentType: "application/javascript",
                        xhrFields: {
                            withCredentials: true
                        },                            
                        processData:false,                
                        beforeSend: function (xhr) {
                            xhr.setRequestHeader("Authorization", 'Basic SUlTVTA5OkludDNyZkBjMw==')
                        },
                        data: { 'inputData': "{PatientID:'12',FromDateTime:'05/21/2013 1:28:15 PM',ToDateTime:'05/21/2013 1:28:15 PM',ResponseType:'json',CompressResponse:'false'}" },                        
                        url: "http://192.168.15.160/ClearVitalsRestAPI/ClearVitalsService/GetMedicationValues",             


                        success: function (jsonData) {
                            console.log(jsonData);
                        },
                        error: function (request, textStatus, errorThrown) {
                            console.log(request.responseText);
                            console.log(textStatus);
                            console.log(errorThrown);
                        }
                    });
    });

我弹出一个浏览器，而不是需要凭据。HTTP 标头如下所示。要求

我在浏览器的登录弹出窗口中单击取消后收集了此标题。

请建议。谢谢。

通过将数据类型更改为 json 而不是 jsonp 解决了这个问题。原因是 jsonp 不允许我的 Web 客户端将授权标头添加到我的请求中。我在堆栈溢出的某个论坛中发现了这个事实。
