Handling Erlang inets http client errors
- by Justin
I have an Erlang app which makes a large number of http calls to external sites using inets, using the code below
case http:request(get, {Url, []}, [{autoredirect, false}], []) of
{ok, {{_, Code, _}, _, Body}}->
case Code of
200 ->
HandlerFn(Body);
_ ->
{error, io:format("~s returned HTTP ~p", [Broker, Code])}
end;
Response -> %% block to handle unexpected responses from inets
{error, io:format("~s returned ~p", [Broker, Response])}
end.
There is an explicit block to handle anything strange inets might return [Response]. Despite this, I still get what look like inets error reports dumped to the console [sample below]. What am I doing wrong here ? Do I need to configure some kind of inets error handler elsewhere ?
Thanks.
