call_rpc

Description: Makes a remote call to a process returning the result to the client in JSON format. Before, After and error actions can be specified using call backs. It takes the following arguments

- $c : Mojolicious::Controller

- $req_storage A hashref of attributes stored with the request. This routine uses some of the following named arguments.

- url, if not specified url set on $self object is used. Must be supplied by either method.

- method, The name of the method at the remote end (this is appened to $request_storage->{url} )

- msg_type, a name for this method if not supplied method is used.

- call_params, a hashref of arguments on top of req_storage to send to remote method. This will be suplemented with $req_storage->{args} added as an args key and be merged with $req_storage->{stash_params} with stash_params overwriting any matching keys in call_params.

- rpc_response_callback, If supplied this will be run with Mojolicious::Controller instance the rpc_response and $req_storage. Note: if rpc_response_callback is supplied the success and error callbacks are not used.

- before_get_rpc_response, array ref of subroutines to run before the remote response, is passed $c and req_storage

- after_get_rpc_response, arrayref of subroutines to run after the remote response, is passed $c and req_storage called only when there is an actual response from the remote call . IE if there is communication error with the call it will not be called versus an error message being returned from the call when it will.

- before_call, arrayref of subroutines called before the request to the remote service is made.

- error, a subroutine reference that will be called with Mojolicious::Controller the rpc_response and $req_storage if a $response->{error} error was returned from the remote call, and $req_storage->{rpc_response_cb} was not passed.

- success, a subroutines reference that will be called if there was no error returned from the remote call and $req_storage->{rpc_response_cb} was not passed.

- rpc_failure_cb, a sub routine reference to call if the remote call fails at a http level. Called with Mojolicious::Controller the rpc_response and $req_storage

Returns undef.
