how to insert a line of code in a specified code block with commands such as sed , awk , and so on.

suppose you have a file hello.php , with the following contents:

  piplin  package, modify the  app/Providers/AppServiceProvider.php  file, and add \ URL::forceScheme ("https") to the code block of the method  function boot () ;  to enable https. The container itself is a php network server, and php components are already installed, so using php to do this is a better solution in this case.
