错误请求调用 WCF 服务 Jquery Ajax

Question

我正在尝试为 Jquery Ajax 获取 JSON 的 WCF 服务，但该方法甚至没有被启动，现在返回错误 Bad Request。

下面是调用服务、服务接口、服务类、服务Web.config、Global.asax服务的Java脚本代码。

详细信息如果我访问 $.getJSON 的 GetData 方法有效，但在 $.Ajax 无效。

已经使用 AddStudant 方法无法以某种方式工作。

谁能帮忙告诉我怎么了？

JavaScript

$("#bt").click(function () {

var url = "http://domain.net/Service1.svc/AddStudant";变量数据 = {“ID”：1，“名称”：“爱立信阿尔维斯”};变量 jdata = {}; jdata.student = 数据；

callAjax(url, 'json', 'POST', 功能（结果）{ 警报（结果）； }, JSON.stringify(jdata) ); });

函数 callAjax(ajaxUrl, ajaxDataType, ajaxType, funcSucess, 数据值）{

    $.ajax({
        url: ajaxUrl,
        dataType: ajaxDataType,
        type: ajaxType,
        data: dataValues,
        processdata: true,
        contentType: "application/json;charset-uf8"
    })
        .done(function (data) {
            funcSucess(data);
        })
        .always(function (data) {

        }).fail(function (xhr, status, errorThrown) {
            alert(xhr.responseText);
        });
}

Answer 1

尝试发送data 而不是jdata，我想您需要像{ "ID": 1, "Name": "Ericsson Alves" } 一样发送对象，而不是像您当前正在发送的那样在另一个对象中发送它{student: { "ID": 1, "Name": "Ericsson Alves" }}

Answer 2

在您的 ajax 请求中将 contentType 设置为 text/plain
