Hi, Instead derived from cppcms::application, my application is derived from cppcms::rpc::json_rpc_server . I would like to populate the dynamic page with data from a request using ajax and json. My Questions are: - Is it a normal usage of cppcms framework because I don't find an example like this within the example that you have provided? - If yes, are there some conditions or some style of code for this kind of usage? Thank you very much. hmaminirina. |

Hi , I would like explain my questions. For example I create my dynamic page (like template or templates_inheritance in the example) with ajax using json_rpc inside: 1. Will I do a derivation from cppcms::appliaction and make a json call inside or 2. Will I do a derivation from cppcms::rpc::json_rpc_server for all application and children. I'd like to know if the context is shared by url dispather and json_rpc_call or they have two different context? Thank you Artyom. ---------- Forwarded message ---------- From: le ba <hma...@gm...> Date: 2012/5/21 Subject: cppcms::rpc::json_rpc_server usage. To: cpp...@li... Cc: art...@ya...

See json_rcp_server is derived from cppcms::application, so everything you have in application you have in the RPC server. So if you use mostly AJAX and JSON-RPC API it makes sence to use json_rpc_server for your code >I'd like to know if the context is shared by url dispather and json_rpc_call or they have two different context? > No, but dispatching member functions would not work AFAIR as it dispatches function calls in main() that is overriden If you want more specific answers be more specific Artyom > |

Hi Artyom,
this is the main overriden that I used:
class numbers : public cppcms::rpc::json_rpc_server {
public:
numbers(cppcms::service &srv) : cppcms::rpc::json_rpc_server (srv)
{
dispatcher().assign("",&numbers::all,this);
mapper().assign("");
}
void main(std:string url)
{
if(!dispatcher().dispatch(url)) {
response().make_error_response(http::response::not_found);
}
cppcms::rpc::json_rpc_server::main(url);
}
};

You really mixing stuff incorrectly because you will never
be able to execute cppcms::rpc::json_rpc_server::main(url); properly
as you already have an output

Hi,
What is the wrong in my code?:
This is my code.

By default cppcms::rpc::json_rpc_server don't dispatches Url by default
like cppcms::application.
My problem is how to dispatch a dynamic page and activate the json_rpc call
after.

Hi Artyom, Thanks for your help, it works fine now . An other article that are very important in cppcms document : "context is a central class that holds all specific connection related information. It encapsulates CGI request and response, cache, session and locale information *Instance of this class is created upon client requests, it provides access to all connection related interfaces*.* This class is unique per each applications hierarchy and destroyed when HTTP request/response is completed *".
