| 2 | Perl interfacing to egroupware: |
---|
| 3 | |
---|
| 4 | The Frontier::RPC module available at CPAN is capable of logging into an |
---|
| 5 | egroupware server. To authenticate your session after the initial login, |
---|
| 6 | however, requires a patch to Frontier. This patch causes Frontier to create |
---|
| 7 | an Authentication header using username/password values. We use the assigned |
---|
| 8 | sessionid and kp3 for this. |
---|
| 9 | |
---|
| 10 | NOTE: sessionid/kp3 values in this file are not valid. |
---|
| 11 | |
---|
| 12 | TODO: |
---|
| 13 | |
---|
| 14 | 1. Apply the patch at the end of this file to Frontier-RPC-0.06. |
---|
| 15 | 2. Install Frontier. |
---|
| 16 | 3. Try the following method using rpc-client.pl in the examples subdirectory for |
---|
| 17 | the Frontier source: |
---|
| 18 | |
---|
| 19 | rpc-client.pl \ |
---|
| 20 | http://www.egroupware.org/egroupware/xmlrpc.php \ |
---|
| 21 | system.login \ |
---|
| 22 | "{domain => '',username => 'demo', password => 'guest'}" |
---|
| 23 | |
---|
| 24 | 4. Take the returned sessionid and kp3, e.g.: |
---|
| 25 | |
---|
| 26 | $result = HASH(0x826d4b0) |
---|
| 27 | 'domain' => 'default' |
---|
| 28 | 'kp3' => 'e0219714614769x25bc92286016c60c2' |
---|
| 29 | 'sessionid' => '36f9ec1e4ad78bxd8bc902b1c38d3e14' |
---|
| 30 | |
---|
| 31 | 5. Place these on the commandline for a new request: |
---|
| 32 | |
---|
| 33 | rpc-client.pl \ |
---|
| 34 | http://www.egroupware.org/egroupware/xmlrpc.php \ |
---|
| 35 | --username 36f9ec1e4ad78bxd8bc902b1c38d3e14 \ |
---|
| 36 | --password e0219714614769x25bc92286016c60c2 \ |
---|
| 37 | service.contacts.read \ |
---|
| 38 | "{ id => '4'}" |
---|
| 39 | |
---|
| 40 | 6. This should return record #4 from the addressbook application. |
---|
| 41 | |
---|
| 42 | |
---|
| 43 | Here is the patch: |
