[AWS] AWS.Parameters.Get

[Adrian Hoe 贺文耀]

Hi Pascal and list,

I have a code snippet:


          --AWS.Parameters.Set.Reset ( Form_Data ) ;
          --AWS.Parameters.Set.Add   ( Form_Data, Column_Record_Id,  
Record_Id ) ;
          --AWS.Status.Set.Read_Header ( AWS.Status.Socket  
( Request ) , D ) ;
          --AWS.Status.Set.Parameters ( D, Form_Data ) ;

          AWS.Response.Set.Read_Header ( AWS.Status.Socket  
( Request ), D ) ;
          AWS.Response.Set.Add_Header ( D, Column_Record_Id,  
Record_Id ) ;
          AWS.Response.Send_Header ( AWS.Status.Socket ( Request ),  
D ) ;

          return AWS.Response.URL ( Location => Locations.Web_Record ) ;


I am trying to redirect to another web URI (Locations.Web_Record). I  
also need to pass some processed data to the URI as if parameters  
posted by <form> post action.

	Locations.Web_Record := "/record";
	Locations.Web_Record_Edit := "/record_edit";
	Locations.Web_Record_Save := "/record_save";

with actions:

	Dispatchers.Record.VIew'access
	Dispatchers.Record.Edit'access
	Dispatchers.Record.Save'access

respectively. The process flow is from View -> Edit -> Save -> View.  
The code snippety above is located in Save which it is supposed to  
process some data and then redirect back to View with parameter as if  
posted by a <form> post action.

I have tried both AWS,Status (commented) and AWS.Response. Both  
methods are trying to load the page but give me error:

Safari can’t open the page.
Safari can’t open the page “http://localhost:8080/record” because  
the server unexpectedly dropped the connection. This sometimes occurs  
when the server is busy. Wait for a few minutes, and then try again.




Am I missing something? Is my method correct? Can you/someone please  
enlighten me? Thanks

Best regards,
