webApi之FromUri和FromBody区别

ublic 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

1 2 3 4 5 6 7

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~
