Service.cs

public class StoredProcService : IStoredProcService
{
    public int addData(int x, int y)
    {
        return x + y;
    }
}

错误：415无法处理消息，因为内容类型'application/json；charset=utf-8'不是预期的类型'text/xml'spx

<script type="text/javascript">
  $(document).ready(function () {
      //$('input[id^="button"]').click(function () {
      //                alert('You have clicked ' + $(this).val());
      Add();
  })
  function Add() {
      alert("sds");
      $.ajax({
          type: 'POST',
          url: '/StoredProcService.svc/addData',
          contentType: 'application/json; charset=utf-8',
          dataType: 'json',
          data: {"x":"5", "y":"8"},
          success: function (data) {
              alert(data);
          }
      });

使用WCF的客户端代码

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);
            }
        });

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

如果出现错误400，请尝试从浏览器访问URL并更正该URL。
