5.5 Using the Key in a Hack
Every time you
send a request to the Google server in a program, you have to send
your key along with it. Google checks the key and determines if
it's valid, and you're still within
your daily 1,000 query limit; if so, Google processes the request.
All the programs in this book, regardless of language and platform,
provide a place to plug in your key. The key itself is just a string
of random-looking characters (e.g.,
12BuCK13mY5h0E/34KN0cK@ttH3Do0R).
A Perl hack usually includes a line like the following:
...
# Your Google API developer's key
my $google_key='insert key here';
...
The Java GoogleAPIDemo included in the Google
Web APIs Developer's Kit is invoked on the command
line like so:
% java -cp googleapi.jar com.google.soap.search.GoogleAPIDemo
insert_key_here search ostrich
In both cases, insert key here or
insert_key_here should be substituted with
your own Google Web API key. For example, I'd plug
my made-up key into the Perl script as follows:
...
# Your Google API developer's key
my $google_key='12BuCK13mY5h0E/34KN0cK@ttH3Do0R';
...
