Hi,

in the application client i run the code (after server)


CONSOLE_APP_MAIN
{
      String url = "http://localhost:8001/myapp/qualqueres";   
      request.Post("id", "1234"); //** < --
      request.PostData("1111111");
      request.POST();
      String content = request.Execute(); 
       
      Cout() << "return " << content ;
  
      SetExitCode( 0 );
}

in the server application i run the code


SKYLARK(q, "qualqueres:POST")
{
   //**  "id" ??  "1234" ??  <--

   String c = http.GetRequestContent();

   http << c;
}

struct MyApp : SkylarkApp {
   MyApp() {
   root = "myapp";
  }
};

CONSOLE_APP_MAIN
{
   MyApp().Run();	
}

in the application client return the result "1111111".

my question:

in this adaptation I did how to make the parameter "id" and its value "1234"
passed by the client application, be read (evaluated) on the server and returned
to the client application?

(ie how do I read the parameters on the server, passed by the client, without manipulating
the traditional html?)

thanks

Hello BetoBValle :

Request from client :

HttpRequest http("http://localhost:8001/serverSkylark/qualqueres");
//	http.POST().Header("id","1234"); //Via request header
//	http.POST().Post("id","1234"); //Via post Data
	http.POST().PostData("{\"id\":\"1234\"}"); //Via post data formated in JSON
	Cout() << http.Execute() << EOL;

Code to return 1234 from server :

SKYLARK(q, "qualqueres:POST")
{
   //String c = http.GetHeader("id"); //Via request header
   //String c =  http["id"]; //Via post data
   
   String c;
   String dataNotParsed = http.GetRequestContent(); //Via Post data formated in JSON
   Value json = ParseJSON(dataNotParsed);
   if(!IsNull(json["id"]))
		c = json["id"];
   
   http << c;
}

Hi,

in app client compiler show error line ...http.POST().Post("id","1234").. error: use of undeclared identifier 'http'

what are the contents of your client app includes?

thanks

My 'http' is your 'request'.

#include <Core/Core.h>

using namespace Upp;

CONSOLE_APP_MAIN
{
	HttpRequest http("http://localhost:8001/serverSkylark/qualqueres");
//	http.POST().Header("id","1234"); //Via request header
//	http.POST().Post("id","1234"); //Via post Data
	http.POST().PostData("{\"id\":\"1234\"}"); //Via post data formated in JSON
	Cout() << http.Execute() << EOL;
}

         http << c;
    }
    struct MyApp : SkylarkApp {
    	MyApp() {
    		root = "myapp";
		
    	#ifdef _DEBUG
    		prefork = 0;
    		use_caching = false;
    	#endif
    	}
    };

    CONSOLE_APP_MAIN
    {
    #ifdef _DEBUG
