Google.cfc v0.3

Why

It took me a few hours to make the Google API work with Cold Fusion. The results of the search API are a complex java object, so there seemed a need for translating this to something more coldfusion native.

Usage

<cfinvoke component="lab.cf.google.google" method="search" returnvariable="googleResults" >
  <cfinvokeargument name="q" value="uzilla"/>
  <cfinvokeargument name="start" value=1/>
  <cfinvokeargument name="maxResults" value="10"
  <cfinvokeargument name="key" value="...">
</cfinvoke>

The search method returns an array of structures with the following keys:

CACHEDSIZE
HOSTNAME
SNIPPET
SUMMARY
TITLE
URL

Change Notes

  • v0.3: Added ability to query for more than just 10 records. Note, for every 10 retrieved, you will use one of your 1000 daily allotted queries.

Future Work

Additional development might support more methods of the google api, optionally return a query instead of a struct. What else? Built-in caching?
