Detailed Description

Concrete implementation of the HTTP response creator used for processing API commands.

See the documentation of the isc::http::HttpResponseCreator for the basic information how HTTP response creators are utilized by the libkea-http library to generate HTTP responses.

This creator expects that received requests are encapsulated in the isc::http::PostHttpRequestJson objects. The generated responses are encapsulated in the HttpResponseJson objects.

This class uses CommandMgr singleton to process commands conveyed in the HTTP body. The JSON responses returned by the manager are placed in the body of the generated HTTP responses.

Constructor & Destructor Documentation

CmdResponseCreator()

isc::config::CmdResponseCreator::CmdResponseCreator ( bool emulate_agent_response = true )

inline

Constructor.

Parameters

emulate_agent_response

if true, responses for normal command outcomes are guaranteed to be wrapped in an Element::list. This emulates how kea-ctrl-agent forms responses. Defaults to true.

Definition at line 40 of file cmd_response_creator.h.

Member Function Documentation

createNewHttpRequest()

HttpRequestPtr isc::config::CmdResponseCreator::createNewHttpRequest ( ) const

virtual

Create a new request.

This method creates a bare instance of the isc::http::PostHttpRequestJson.

Returns

Pointer to the new instance of the isc::http::PostHttpRequestJson.

Implements isc::http::HttpResponseCreator.

Definition at line 31 of file cmd_response_creator.cc.

createStockHttpResponse()

HttpResponsePtr isc::config::CmdResponseCreator::createStockHttpResponse ( const http::HttpRequestPtr & request, const http::HttpStatusCode & status_code ) const

virtual

Creates stock HTTP response.

Parameters

request	Pointer to an object representing HTTP request.
status_code	Status code of the response.

Returns

Pointer to an isc::http::HttpResponseJson object representing stock HTTP response.

Implements isc::http::HttpResponseCreator.

Definition at line 36 of file cmd_response_creator.cc.

emulateAgentResponse()

bool isc::config::CmdResponseCreator::emulateAgentResponse ( )

inline

Indicates whether or not agent response emulation is enabled.

Returns

true if emulation is enabled.

Definition at line 65 of file cmd_response_creator.h.

filterCommand()

HttpResponseJsonPtr isc::config::CmdResponseCreator::filterCommand	(	const http::HttpRequestPtr &	request,
		const data::ConstElementPtr &	body,
		const std::unordered_set< std::string > &	accept )

Filter commands.

From RBAC code: if the access list is empty or the command cannot be found just return.

Parameters

request	The HTTP request (for the HTTP version).
body	The request body.
accept	The accept access list.

Member Data Documentation

command_accept_list_

unordered_set< string > isc::config::CmdResponseCreator::command_accept_list_

static

The server command accept list.

Default to the empty list which means to accept everything.

Definition at line 94 of file cmd_response_creator.h.

Referenced by isc::ha::HAService::HAService().

http_auth_config_

HttpAuthConfigPtr isc::config::CmdResponseCreator::http_auth_config_

static

The server current authentication configuration.

Default to the empty HttpAuthConfigPtr.

Note

: This is currently not used, except in unit-tests. For the time being, we postponed writing the corresponding code in the HA, so http_auth_config_ is left to its empty default value.
