Answer 1

默认情况下，所有WCF通信都使用XML进行。尝试更正您的javascript：

function Add() {
        alert("sds");
        $.ajax({
            type: 'POST',
            url: '/StoredProcService.svc/addData',
            contentType: 'text/xml; charset=utf-8',
            dataType: 'xml',
            data: {"x":"5", "y":"8"},
            success: function (data) {
                alert(data);
            }
        });

Answer 2

将ajax调用中的内容类型更改为contentType: 'text/xml; charset=utf-8'它应该可以正常工作。

如果您收到错误400，请尝试从浏览器访问网址并更正网址。

使用WCF
