ページの必要なコンテンツを取得するために `wget`にGETメソッドを使用させるにはどうすればよいですか？

"man wget"から：

           This example shows how to log in to a server using POST and then proceed to download the desired pages, presumably only accessible to authorized
       users:

               # Log in to the server.  This can be done only once.
               wget --save-cookies cookies.txt \
                    --post-data 'user=foo&password=bar' \
                    http://example.com/auth.php

               # Now grab the page or pages we care about.
               wget --load-cookies cookies.txt \
                    -p http://example.com/interesting/article.php

       If the server is using session cookies to track user authentication, the above will not work because --save-cookies will not save them (and neither
       will browsers) and the cookies.txt file will be empty.  In that case use --keep-session-cookies along with --save-cookies to force saving of session
       cookies.
