Constructor & Destructor Documentation

pion::http::cookie_auth::cookie_auth ( user_manager_ptr  userManager,
const std::string &  login = "/login",
const std::string &  logout = "/logout",
const std::string &  redirect = "" 
)

default constructor

Parameters:
userManager 
login - URL resource for login request. Typical login request has format: http://website/login?user="username"&pass="password"&url="redirection_url"
logout - URL resource for logout request. Typical logout request has format: http://website/logout?url="redirection_url"
redirect - if not empty, URL for redirection in case of authentication failure if empty - send code 401 on authentication failure

bool pion::http::cookie_auth::handle_request ( http::request_ptr &  http_request_ptr,
tcp::connection_ptr &  tcp_conn 
) [virtual]

attempts to validate authentication of a new HTTP request. If request valid, pointer to user identity object (if any) will be preserved in the request and return "true". If request not authenticated, appropriate response is sent over tcp_conn and return "false";

Note: if request matches "login" resource, then login sequences attempted. If "name" and "pass" attributes match user definition, a random cookie is created and associated with given user session. If request contains "url" attribute, then page redirection response returned. Otherwise - empty 204 response.

Parameters:
http_request_ptr the new HTTP request to handle
tcp_conn the TCP connection that has the new request
Returns:
true if request valid and user identity inserted into request

void pion::http::cookie_auth::handle_unauthorized ( http::request_ptr &  http_request_ptr,
tcp::connection_ptr &  tcp_conn 
) [protected]

used to send responses when access to resource is not authorized

Parameters:
http_request_ptr the new HTTP request to handle
tcp_conn the TCP connection that has the new request

bool pion::http::cookie_auth::process_login ( http::request_ptr &  http_request_ptr,
tcp::connection_ptr &  tcp_conn 
) [protected]

check if given request is a login/logout and process it

Parameters:
http_request_ptr the new HTTP request to handle
tcp_conn the TCP connection that has the new request
Returns:
true if it was a login/logout request and no future processing required.

void pion::http::cookie_auth::set_option ( const std::string &  name,
const std::string &  value 
) [virtual]

sets a configuration option Valid options:

  • "login" - URL resource for login request. Typical login request has format: http://website/login?user="username"&pass="password"&url="redirection_url"
  • "logout" - URL resource for logout request. Typical logout request has format: http://website/logout?url="redirection_url"
  • "redirect" - if not empty, URL for redirection in case of authentication failure if empty - send code 401 on authentication failure
Parameters:
name the name of the option to change
value the value of the option
