Question

我需要在web api中使用接收json的方法，但其结构是动态的。我尝试使用以下代码，但值始终为null。

(ql:quickload :cffi)


(cffi:load-foreign-library "user32.dll")

(cffi:load-foreign-library "kernel32.dll")

(cffi:load-foreign-library "msvcrt.dll")


(cffi:defcfun ("GetClipboardData" get-clip) :string

(uformat  :unsigned-int))


(cffi:defcfun ("OpenClipboard" open-clip) :int

  (hOwner  :unsigned-int))


(cffi:defcfun ("CloseClipboard" close-clip) :int


      (hOwner  :unsigned-int))


(cffi:defcfun ("EmptyClipboard" empty-clip) :int)


(cffi:defcfun ("SetClipboardData" set-clip) :int

  (data  :unsigned-int)

  (format :unsigned-int))


(cffi:defcfun ("GlobalAlloc" global-alloc) :int

  (flags  :unsigned-int)

  (numbytes :unsigned-int))


(cffi:defcfun ("GlobalLock" global-lock) :unsigned-int

  (typ  :unsigned-int))


(cffi:defcfun ("GlobalLock" global-lock-string) :string 

  (typ  :unsigned-int))


(cffi:defcfun ("GlobalUnlock" global-unlock) :int

  (typ  :unsigned-int))


(cffi:defcfun ("memcpy" memcpy) :int

  (dest  :unsigned-int)

  (src :string) 

  (coun :unsigned-int))



(defun get-clip-string ()

          (open-clip 0)

          (let* ((h (get-clip 1)) (s (global-lock-string h)))

                 (global-unlock h) (close-clip 0) s))


(defun set-clip-string (s)

          (let* ((slen (+ 1 (length s)))(newh (global-alloc 8194 slen))

(newp (global-lock newh)))

          (memcpy newp s (+ 1 slen)) (global-unlock newh) (open-clip 0)

(set-clip 1 newh) (close-clip 0)))

使用这个json

[HttpPost]
public class TestController : Controller
{
   public JsonResult DoJob(dynamic value)
    {
       //Work with parameter
    }     
}

更新这是我从客户端发送请求的方式

{"testObject":{"property":"value"}, "otherPropery": "otherValue"}

我认为，如果你做的话，json结果它等同于字符串

[HttpPost]
public class TestController : Controller
{
   public JsonResult DoJob(string value)
    {
       //Work with parameter
    }     
}

它应该有用

ASP.NET Web api POST方法动态参数为null
