If its clear text and you have the right flags set it will show you all of the raw data.
Wireshark can in many cases decode it further.
However if it ssl/tls encrypted there is a tool much to most infosec peoples dismay (and joy when its useful ) called ssldump that can take a tcpdump that captures the full conversation and decode it.
But that answered is no not out of the box.
