defaultPort() -> 2000.

fileNameToGet() -> "file_client.erl".
|
|
|
|
%% Prerequisites:
|
|
%%
|
|
%% 1. The current working directory must be ".", because test() will
|
|
%% try to access the file fileNameToGet().
|
|
%%
|
|
%% 2. If the UBF server is not listening on "localhost", then your OS
|
|
%% environment variable "WHERE" must be set to the hostname of the
|
|
%% UBF server's DNS name (or, alternately, the UBF server's IP
|
|
%% address). See the host() function for details.
|
|
%%
|
|
%% 3. A UBF server must be listening to TCP port defaultPort() and
|
|
%% have the "file_server" contract, which is implemented by the
|
|
%% "file_plugin" module.
|
|
%%
|
|
%% Here is minimal recipe.
|
|
%%
|
|
%% erl -pz ../../ebin
|
|
%%
|
|
%% > ubf_server:start(undefined, [file_plugin], file_client:defaultPort(), []).
|
|
%% > ok = file_client:test().
|
|
|
|
test() ->
|
|
{ok, Pid, _Name} = ubf_client:connect(host(), defaultPort()),
|
|
|
|
{reply, Info, _} = ubf_client:rpc(Pid,
|
|
{startSession, ?S("file_server"), []}),
|
|
io:format("Info = ~p~n",[Info]),
|
|
|
|
{reply, {files, Fs}, start} = rpc(Pid, ls),
|
|
Files = map(fun(?S(I)) -> I end, Fs),
|
|
io:format("Files=~p~n",[Files]),
|
|
|
|
FileName = fileNameToGet(),
|
|
{reply, X, start} = rpc(Pid, {get, ?S(FileName)}),
|
|
io:format("got ~p bytes for ~s~n",[size(X), FileName]),
|
|
|
|
ubf_client:stop(Pid),
|
|
io:format("test worked~n"),
|
|
ok.
|
|
|
|
host() ->
|
|
case os:getenv("WHERE") of
|
|
false -> "localhost";
|
|
"HOME" -> "localhost";
