  hub method return object object

  May 30, 2019 06:54 AM|erum|LINK

  I have below hub method

   public  string   getConnections()
          {
              users usr = new users();
              List<users> userList = new List<users>();
            
              usr.Currentid = Context.ConnectionId;
              userList.Add(usr);
          
              return usr.Currentid;
          }

  and here is ajax calling 

    function updateNotificationCount() {
                  alert("updateNotificationCount")
                 
                  var connid = chat.server.getConnections();
                  alert("connid" + connid)
                  $.ajax({
                      type: "POST",
                      url: "/LetsChat/GetOnlineusers?connid=" + connid,
                   //   url: "/LetsChat/GetOnlineusers",
                    //  url :  chat.server.getConnections(),
                      //   data: JSON.stringify({ values: valueArray.toString() }),
                      contentType: "application/json; charset=utf-8",
                    //  data: connid,
                      dataType: "json",
                      success: function (response) {
                          debugger;
                          $('#notiContent').empty();
                          if (response.length == 0) {
                              $('#notiContent').append($('<li>Currently You Have No New Notifications.</li>'));
                          }
                          $.each(response, function (index, value) {
                              $('#notiContent').append($('<li>The User , ' + value.Name + '&nbsp;' + 'Of ID' + ' (' + value.ID + ') Is Written Something.</li>'));
                          });
                      },
                      error: errorFunc
                  });
  
              }

  Hi erum,

  erum

  public  string   getConnections()

  erum

  var connid = chat.server.getConnections();

  erum

  it show [object object] rather than connection id

  In your code, we can find that your hub method getConnections that has string type return value, to get the server response, please modify the code like below, which work well on my side.

  chat.server.getConnections().done(function (connid) {
      alert("connid" + connid);
      //console.log(connid);
  }).fail(function (error) {
      console.log('Error: ' + error);
  });

  Test Result:
