Shell Programming and Scripting

Hi,i have a code fragment below.

Code:

%tag = (); #line 1
  $tag{'info'} = $datastring; #line 2
  $resp = $ua->request(  #$ua is a user agent
       POST 'http://10.2.3.0' ,
       Content_Type  => application/x-www-form-urlencoded
       Content       => [ %tag ] #line 3

I am not sure of what the code does. would appreciate if anyone can correct me.
line 1 is to declare an empty hash
line 2 is to assign the value $datastring to the key 'info'
line 3 is to assign the hash to Content. will this just assign the values or it will also assign the keys and values to Content?

correct
correct
the hash is being assigned. hash consists of keys and values. both keys and values would be assigned to Content.

Strictly speaking, I think what is being assigned is a reference to an array, the elements of which are the keys and values of the hash %tag (which are the string 'info' and the value of the variable $datastring)

I will be inclined to say that if you have some basic knowledge Perl, you will understand the syntax used on those 3 lines. But they alone do not make much sense in my opinion. It's actually what the code does that is more important.

So are you working on a program using HTTP::Request? If so, please take a look at the POD for the module. It will tell you what methods are provided, and the arguments you need to use. Then, you simply provide the arguments as needed.
