    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.

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

    1. Check docs: http://www.aspnetboilerplate.com/Pages/ ... ptionEvent (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.
