调用WebAPI的Angularjs控制器总是导致失败回调

Question

我有一个WebAPI端点，如代码片段1和AngularJS，如Code Snippet 2.我将代码跟踪到WebAPI，并调用post方法。模型绑定还绑定到请求正文中的正确模型。它还返回OK状态。在Internet Explorer的开发人员工具（F12）的“网络摘要”选项卡中，“结果”列为200，json数据位于“网络详细信息”选项卡的响应正文中。但是，失败回调总是在AngularJS控制器的consultFactory.save（）中执行。有谁知道为什么？感谢。

[HttpPost]
public IHttpActionResult Post([FromBody] ConsultRequest consultRequest) {
  if (consultRequest == null)
    return BadRequest("consult request cannot be null");
  var response = TheRepository.GetConsultsWithDetails(consultRequest);

  if (response == null)
    return NotFound();

  response = response
    .OrderBy(r => r.RequestDateTime)
    .Take(consultRequest.Take);

  return Ok(response);
}

function getConsults(consultRequest) {
  $log.log('consultRequest', consultRequest);

  debugger;

  consultFactory.save(consultRequest,
    function(data) {
      $log.log('consult-list.component.getConsults() ::: succeeded in retrieving data from consult factory', data);
      $log.log('consult-list.component.getConsults() ::: total consults', data.length);
      vm.consults = data;
      vm.isBusy = false;
      vm.ActiveCount = ($filter("filter")(data, {
        orderStatus: 'ACTIVE'

      vm.errorMessage = response.statusText + "\r\n";
