  Hi,

  You can always create regular web api controller and call them from any platform. For dynamic web api layer, it should be called with POST and with JSON input/output. Just call .../api/services/Assistant/customer/getAllCustomer with POST and get JSON result.

  Thanks for your reply. :D I have added a web api controller,but it still has something confusing me :(

  when use the method get ,it's all ok. use the method post without parameter,it' s still noting wrong. but when use the method post with parameters,it returns error"an internal error occured during your request"

  here's my code: controller:

  public class ContactController : AbpApiController
      {
          Contact[] contacts = new Contact[] { 
              new Contact(){ ID=1, Age=23, Birthday=Convert.ToDateTime("1977-05-30"), Name="Jone", Sex="M"},
              new Contact(){ ID=2, Age=55, Birthday=Convert.ToDateTime("1937-05-30"), Name="Brown", Sex="M"},
              new Contact(){ ID=3, Age=12, Birthday=Convert.ToDateTime("1987-05-30"), Name="Lily", Sex="F"},
              new Contact(){ ID=4, Age=18, Birthday=Convert.ToDateTime("1997-05-30"), Name="Lucy", Sex="F"},
          };
  
          [HttpGet]
          public virtual IEnumerable<Contact> GetListAll()
          {
              return contacts;
          }
  
          [HttpPost]
          public virtual IEnumerable<Contact> QueryLists([FromBody]int state)
          {
              return contacts.Where(con=>con.ID==state);
          }
    }
  

  the method get:

  $('#send_ajax').click(function(){
                  $.ajax({
                      url:'http://...../api/Contact/GetListAll',
                      type:'get',
                      data:{},
                      success:function(data){
                          //alert(data);
                      },
                      error:function(data){
                          //var myjson='';
                      }
                  });
              });
  

  the result:

  [{"id":1,"name":"Jone","sex":"M","birthday":"1977-05-30T00:00:00","age":23},{"id":2,"name":"Brown","sex":"M","birthday":"1937-05-30T00:00:00","age":55},{"id":3,"name":"Lily","sex":"F","birthday":"1987-05-30T00:00:00","age":12},{"id":4,"name":"Lucy","sex":"F","birthday":"1997-05-30T00:00:00","age":18}]
  

  the method post :

  $('#send_ajax').click(function(){
                  $.ajax({
                      url:'http://....../api/Contact/QueryLists',
                      type:'post',
                      data:{"state":1},
                      success:function(data){
                          //alert(data);
                      },
                      error:function(data){
                      }
                  });
              });
  

  the result:

  {"success":false,"result":null,"error":{"code":0,"message":"An internal error occurred during your request!","details":null,"validationErrors":null},"unAuthorizedRequest":false}
  

  Do you have some solutions ?waitting for your good news.

  Have you checked the internal error? You can find it in Logs folder in web project.

  This seems not related to ABP. But you can try a few things more to know what's is the error:

  1. Check docs: <a class="postlink" href="http://www.aspnetboilerplate.com/Pages/Documents/Handling-Exceptions#DocExceptionEvent">http://www.aspnetboilerplate.com/Pages/ ... ptionEvent</a> (Exception event section) to get handled exception details. You can add a breakpoint into HandleEvent and check eventData.Exception object.

  2. Check network tab of Chrome to see returned result in detail.
