How to set HTTP User-Agent for VLC?

问题

I am using VLC's command line option --http-user-agent, but it does not seem to work.

My command is

$ vlc --http-user-agent 'FooBar/1.2.3' 'http://wiki.videolan.org/'

And when I use tcpdump -Xlnn dst port 80 to capture the packets, I see

0x0030:  8eff 035b 4745 5420 2f20 4854 5450 2f31  ...[GET./.HTTP/1
0x0040:  2e31 0d0a 486f 7374 3a20 7769 6b69 2e76  .1..Host:.wiki.v

0x00b0:  6573 3d30 2d0d 0a0d 0a                   es=0-....

which means that the User-Agent part is not changed (still the default of VLC).

Am I misunderstanding the usage of this option? Or is this a bug in VLC?

My version is VLC media player 3.0.2 Vetinari (revision 3.0.2-0-gd7b653cf14)

回答1:

$ vlc 'http://wiki.videolan.org/' :http-user-agent='FooBar/1.2.3' seems to do the trick (replaced -- by : and put the attribute after the url). I guess this is probably the way how the windows version expects the attributes, since in the GUI, you also have to add those attributes starting with : (I've only evaluated this from the VLC debug logs)

回答2:

I was able to set the User-Agent only using a LUA script: (where the command line methods didn't work)

$ cat play.lua 
#EXTVLCOPT:http-user-agent=Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.25 Safari/537.36
#EXTVLCOPT:http-referrer=https://playme.com/i-came-from-this-page-i-sware

$ VLC play.lua

VLC's command-line argument help page's states you need to use = to associate a value with an argument name.

https://wiki.videolan.org/VLC_command-line_help/

 --http-user-agent=<string> User agent

Try this:

$ vlc --http-user-agent='FooBar/1.2.3' 'http://wiki.videolan.org/'
