Answer 1

Use your browser to access youtube:
w3m www.youtube.com
links www.youtube.com
To be able to return to the normal homepage (of course it is a text-only version, the page returned is a very bad page with no pictures, but it can be recognized as YouTube)

Get youtube homepage:
curl www.youtube.com
wget www.youtube.com
To be able to correctly obtain the code of the YouTube homepage.

You can also use facebook, etc. for testing.
