webApi之FromUri和FromBody区别

 　　　　public Link GetLink([FromUri] FileRequest fileRequest)
        {
            if (ModelState.IsValid)
            {
                var xml = WebConfigurationManager.AppSettings["appDiscoveryXml"];
                var wopiServer = WebConfigurationManager.AppSettings["appWopiServer"];
                bool updateEnabled = false;
                bool.TryParse(WebConfigurationManager.AppSettings["updateEnabled"], out updateEnabled);
                WopiAppHelper wopiHelper = new WopiAppHelper(HostingEnvironment.MapPath(xml), updateEnabled);

                var result = wopiHelper.GetDocumentLink(wopiServer + fileRequest.name);

                var rv = new Link
                {
                    Url = result
                };
                return rv;
            }

            throw new ApplicationException("Invalid ModelState");
        }

　

　　FileRequest类的定义

 　　public class FileRequest
    {
        public string name { get; set; }

        public string SelectedItemId { get; set; }
        public IEnumerable<SelectListItem> Items { get; set; }
    }

　　

　这里的FromUri强制从url中读取FileRequest 对象，也就是说

　　　　当访问Http://localhost:80?name=eric&SelectedItemId={Guid.NewGuid()}

   此处将自动转换Uri中的参数作为对象属性忽略form传递的数据

而使用FromBody将强制从FormData中读取数据

而非URL中获取参数~
