从SharePoint Javascript表单加载JSON响应

首先，很抱歉我的英语如此混乱，我会尽力解释我的问题。 我在azure web应用程序中运行WCF服务。该服务接收一个参数并以JSON显示一些HR数据。在调试和生产中，该服务运行良好。此外，我还有一个定制的sharepoint列表表单（在一个好的场景中），它接收JSON响应并显示数据。 在过去，一家雇佣的公司部署了此解决方案，并且工作良好，直到承载WCF服务的服务器关闭。现在我正在部署一个新服务，我想将该服务与表单连接起来。我尝试使用sharepoint designer更改ASPX自定义表单中的WCF路由，但在加载时不起作用。我不想改变形式，数量的文本框或他们的订单。只有我想在表单中显示JSON响应

这是自定义表单中的javascript代码。此代码在公司关闭原始服务器之前工作，此代码绝对没有任何更改，只有wcf地址

<script type="text/javascript">
        ExecuteOrDelayUntilScriptLoaded(Initialize, "sp.js");
        function Initialize() {
            console.log(_spPageContextInfo);
            var settings = {
              "async": true,
              "crossDomain": true,
              "url": "http://mytestserver.azurewebsites.net/Service.svc/ObtainEmp/" + _spPageContextInfo.userEmail,
              "method": "GET"
            }

            $.ajax(settings).done(function (response) {
              var person = response.ObtainEmpResult;
              $('#nameemp').text(person.Name + ' ' + person.FirstName + ' ' + person.SecondName);
              var CardCode = getTagFromIdentifierAndTitle("input", "", "Identification");
              $(CardCode).val(person.Identification);
              $(CardCode).prop('readonly', true);
              var numberemp = getTagFromIdentifierAndTitle("input", "", "Employee Number");
              $(numberemp).val(person.EmpCode);
              $(numberemp).prop('readonly', true);
              var position = getTagFromIdentifierAndTitle("input", "", "Position");
              $(position).val(person.Position);
              $(position).prop('readonly', true);
              var dept = getTagFromIdentifierAndTitle("input", "", "Dept");
              $(dept).val(person.Dept);
              $(dept).prop('readonly', true);
              $('#cumulativedays').text(person.ObtainedVacationDays);
              $('#avdays').text(person.AvailableDays);
            });
        }
        function getTagFromIdentifierAndTitle(tagName, identifier, title) {
            var len = identifier.length;
            var tags = document.getElementsByTagName(tagName);
            for (var i = 0; i < tags.length; i++) {
                var tempString = tags[i].id;
                if (tags[i].title == title && (identifier == "" || tempString.indexOf(identifier) == tempString.length - len)) {
                    return tags[i];
                }
            }
            return null;
        }

        function PreSaveAction(){
          var CardCode = getTagFromIdentifierAndTitle("input", "", "Identification");
          $(CardCode).prop('readonly', false);
          var numberemp = getTagFromIdentifierAndTitle("input", "", "Employee Number");
          $(numberemp).prop('readonly', false);
          var position = getTagFromIdentifierAndTitle("input", "", "Position");
          $(position).prop('readonly', false);
          var dept = getTagFromIdentifierAndTitle("input", "", "Dept");
          $(dept).prop('readonly', false);
          return true;
        }

我对javascript sharepoint表单了解不多，我想学习并解决这个问题。正如我所说的，WCF服务在生产环境中运行良好（托管在azure中），因此问题可能出在javascript代码中

谢谢你的帮助。非常感谢

您是否尝试在浏览器中发布wcf URL以查看其是否解决问题？是否尝试从javascript与wcf服务对话？一条小小的建议——如果没有库，就不要这样做，它会给你带来巨大的麻烦。我能建议的最好的方法是在你的c端调用一个api，并从那里传递它。是的，它可以工作。显然，出于安全原因，我更改了这篇文章中的url，但更改了原始urlresolves@MarkDavies我怎么做到的？？我是这方面的新手看看
