web api post

標籤：http   os   io   re   c   cti   ar   new   

這是顯示端

function load() {
$.ajax({
type: "post",
url: "http://localhost:63211/api/MeetingRoomService/AddMeetiongType",
dataType: "json",
data: { "Typename": "123" },
success: function (data) {
renderContactList(data);
alert(data.data);
},error: function (XMLHttpRequest, textStatus, errorThrown) {

alert(data.data);
}
});
}

這是服務端

[HttpPost]
public ResultEntity<bool> AddMeetiongType([FromBody]MeetingType mt)
{
ExceptionManager.Handle(new Exception("TypeName>>>>>>" + mt.Typename));
ResultEntity<bool> result = new ResultEntity<bool>();
result.errors = new List<ErrorEntity>();
ErrorEntity error = new ErrorEntity();
result.action_code = ActionCode.SUCCESS.ToString();
try
{
Check.CheckParameter(mt.Typename);
if (bll.GetMeetingRoomTypeExist(mt.Typename) == false)
{
if (bll.AddMeetingRoomType(mt.Typename))
{
error.message = "插入成功";
result.data = true;

}
else
{
result.action_code = ActionCode.FAILED.ToString();
error.message = "插入失敗";
result.data = false;

}
}
else
{
result.action_code = ActionCode.FAILED.ToString();
error.message = "此資訊已經存在";

}

}
catch (ArgumentException e)
{
ExceptionManager.Handle(e);
result.action_code = ActionCode.FAILED.ToString();
error.message = e.Message;
}
catch (Exception ex)
{
ExceptionManager.Handle(ex);
result.action_code = ActionCode.FAILED.ToString();
error.message = "添加類型介面出錯了！";
}
result.errors.Add(error);
return result;
}

第一個 web api post的程式

今天居然忘記了判斷一個dataset是否為空白的方法

ds.Tables[0].Rows.Count >0
