Each directory (or sub-directory of 'gae') contains an example server |
|
||||||
in a particular language designed to handle audio incoming from the |
|
||||||
Wami recorder. |
|
||||||
|
|
||||||
The PHP example requires the configuration of a PHP-enabled |
|
||||||
web-server, while the python server can be run on any machine with |
|
||||||
python installed. |
|
||||||
|
|
||||||
If you do not wish to host your own server, you can try out the Google |
|
||||||
App Engine (GAE) examples. The GAE python example stores data in a |
|
||||||
"blobstore", for which Google provides a handy web-based management |
|
||||||
console. |
