I tired

 RewriteRule ^开发者_如何学Pythonuser/(.*) profile.php?user=$1 [L]
    RewriteRule ^user/(.*) profile.php?user=$1 [L]
    RewriteRule ^user/(.*)/(.*)/ profile.php?user=$1&v=$2 [L]
    RewriteRule ^user/(.*)/(.*) profile.php?user=$1&v=$2 [L]

But it didn't work like i wanted. I want it to work with all 4 possible urls. What should i do?

Use a more specific pattern than .* like [^/]+ and use /?$ to make the trailing slash optional:

RewriteRule ^user/([^/]+)/?$ profile.php?user=$1 [L]
RewriteRule ^user/([^/]+)/([^/]+)/?$ profile.php?user=$1&v=$2 [L]

But as I recommend to just use one of the formats (with or without trailing slash), remove or add the trailing slash if it is present or missing:

# remove trailing slash
RewriteRule (.*)/$ /$1 [L,R=301]

# add trailing slash
RewriteCond %{REQUEST_URI} !-f
RewriteCond %{REQUEST_URI} !-d
RewriteRule .*[^/]$ /$0/ [L,R=301]
