How can I use computer to control other computer at the same time? I try to use rednet but it can only send message but cna't send command . If you can give a detailed solution or code, that's even better. Thanks for your help!

You need a program on the receiver side, and make the program execute the command you have sent.

An easy example will be:

while true do
  local _, command = rednet.receive()
  local parsedCommand, err = load(command)
  if parsedCommand then
    local result = {parsedCommand()}
    -- and send back the result if you want
  end
end

The controller just send or broadcast Lua commands.
If you want execute shell command, just use shell.run instead of load

Note: In actual use, you may want define protocol, and add encrypt & signature to keep your computer in secure

Now I've managed to control the computer remotely, but how can I achieve typing in the computer from the host computer when I need to type in certain links?

You need a fake term and forward events from one computer to another.

This is my example of a fake term that forward a program's output to web browser through websocket. It's simple and not optimized, and if you search on web there should be more examples you can look at.
