A verbose connection provides much more information about the flow of information between the client and server.
verbose(data_out = TRUE, data_in = FALSE, info = FALSE,
ssl = FALSE)
Show data sent to the server.
Show data recieved from the server.
Show informational text from curl. This is mainly useful for debugging https and auth problems, so is disabled by default.
Show even data sent/recieved over SSL connections?
verbose()
uses the following prefixes to distinguish between
different components of the http messages:
*
informative curl messages
->
headers sent (out)
>>
data sent (out)
*>
ssl data sent (out)
<-
headers received (in)
<<
data received (in)
<*
ssl data received (in)
with_verbose()
makes it easier to use verbose mode
even when the requests are buried inside another function call.
Other config: add_headers
,
authenticate
, config
,
set_cookies
, timeout
,
use_proxy
, user_agent
