I have been in the general processing procedure for less than the value, it is null, debugging but on my Request the Request payLoad inside have their fill of value and the file

CodePudding user response:

FormData. Append (" FPWJ fileobj)

The HttpPostedFile postedFile=HttpContext. Current. Request. Files/" FPH_file "
The HttpPostedFile up_file=context. Request. Files (" FPWJ ");
The HttpPostedFile newup_file=context. Request. Files (" FPH_file ");
A moment FPH_file FPWJ for a while, what the hell?

It should be
The HttpPostedFile postedFile=context. Request. Files/" FPWJ "!
Or directly
The HttpPostedFile postedFile=context. Request. Files [0]
