Httpcontext.request（“”）正在返回ashx处理程序中的空值

Question

在application/x-www-form-urlencoded格式中发布一些数据到我的ashx处理程序。 httpcontext.request.params显示空值。我不知道什么是错的。这是我的代码，并且非常确定我已经在Postman休息客户端中发布了密钥和值。

 <%@ WebHandler Language="VB" Class="Repository" %> 

    Imports System 
    Imports System.Web 
    Imports System.IO 

    Public Class Repository : Implements IHttpHandler

currency2 As String, status As Integer, status_text As String, email As String, custom As String 
Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest 



    If context.Request("ipn_mode") = "" Then 
     context.Response.Write("An Error Occured") 
     Exit Sub 
    End If 

     If context.Request("merchant") = "" Or context.Request("merchant") <> Trim(cp_merchant_id) Then 

      context.Response.Write("No or incorrect Merchant ID passed")

     context.Response.Write("Payment Error") 
    Else 
     'payment is pending, you can optionally add a note to the order page 
     context.Response.Write("Payment Pending") 
    End If 


End Sub 

    Public ReadOnly Property IsReusable() As Boolean Implements IHttpHandler.IsReusable 
    Get 
     Return False 
    End Get 
End Property 

End Class

它应该工作。请确保Content-Type设置为application/x-www-form-urlencoded in 标头，并将值作为关键值对放在主体中。

Content-Type : application/x-www-form-urlencoded
