gun:data - Stream the body of a request
data(ConnPid, StreamRef, IsFin, Data) -> ok ConnPid :: pid() StreamRef :: reference() IsFin :: fin | nofin Data :: iodata()
Stream the body of a request.
This function can only be used if the original request had headers indicating that a body would be streamed.
All calls to this function must use the nofin
flag except for the last which must use fin
to indicate the end of the request body.
Empty data is allowed regardless of the value of IsFin
. Gun may or may not send empty data chunks, however.
The pid of the Gun connection process.
Identifier of the stream for the original request.
Whether this message terminates the request.
All or part of the response body.
The atom ok
is returned.
StreamRef = gun:put(ConnPid, "/lang/fr_FR/hello", [ {<<"content-type">>, <<"text/plain">>} ]). gun:data(ConnPid, StreamRef, nofin, <<"Bonjour !\n">>). gun:data(ConnPid, StreamRef, fin, <<"Bonsoir !\n">>).
