如何从内存位置访问Perl对象？

Question

I want to access a Perl object in a script, which has been passed through Ajax.

I can't pass the object itself through JS Ajax, so I passed in the memory location for the object I want to access.

Now in the Perl script I have a memory location, for example

my $obj = "ClassName=HASH(0x9dccdb18)";

Now if I want to access the actual object for ClassName from this string of memory location, how can I do it?

I want to be able to access the object and run the subroutines on that object.

You can't. Some of the reasons are spelled out in the comments. One additional reason is that even if you were to arrange to return the string to the same processes that generated it, there is no way you can be sure that the object still exists, or that if it does it still lives at the same memory location. The only purpose of that string is to give the object a unique name.

You probably need to read perldoc Storable . You definitely need to ask about the actual problem you're trying to solve rather than something you think may be a solution to it.
