I got it. Need <CR>/enter to normal mode.
nnoremap cP :let @p=expand('%:p')<CR>:norm "pp<CR>

By the way, I find another my environment operation bug.
For example, I need add the 'cP' shortcut function into my _vimrc. I am not sure the first time I will do it right. So I need save my editing file status into a file by using 'mksession' command. Now I have two files 'test.txt' and '_vimrc' in editing.
But mksession will save the gvim startup _vimrc contents, not the _vimrc file that I changed it. So next time when I open gvim, still load the old _vimrc. My _vimrc changes not affected.

When I write a vim script, how can I debug quickly?
I will open a new topic.
