|---|
| 984 | |
|---|
| 985 | =head1 SYNOPSIS |
|---|
| 986 | |
|---|
| 987 | An Atom Publishing API interface for communicating with Movable Type. |
|---|
| 988 | |
|---|
| 989 | =head1 METHODS |
|---|
| 990 | |
|---|
| 991 | =head2 $app->xml_body() |
|---|
| 992 | |
|---|
| 993 | Takes the content posted to the server and parses it into an XML document. |
|---|
| 994 | Uses either XML::LibXML or XML::XPath depending on which is available. |
|---|
| 995 | |
|---|
| 996 | =head2 $app->iso2epoch($iso_ts) |
|---|
| 997 | |
|---|
| 998 | Converts C<$iso_ts> in the format of an ISO timestamp into a unix timestamp |
|---|
| 999 | (seconds since the epoch). |
|---|
| 1000 | |
|---|
| 1001 | =head2 $app->init |
|---|
| 1002 | |
|---|
| 1003 | Initializes the application. |
|---|
| 1004 | |
|---|
| 1005 | =head2 $app->get_auth_info |
|---|
| 1006 | |
|---|
| 1007 | Processes the request for WSSE authentication and returns a hash containing: |
|---|
| 1008 | |
|---|
| 1009 | =over 4 |
|---|
| 1010 | |
|---|
| 1011 | =item * Username |
|---|
| 1012 | |
|---|
| 1013 | =item * PasswordDigest |
|---|
| 1014 | |

| 1019 | =back |
|---|
| 1020 | |
|---|
| 1021 | =head2 $app->handle_request |
|---|
| 1022 | |
|---|
| 1023 | The implementation of this in I<MT::AtomServer::Weblog> passes the request |
|---|
| 1024 | to the proper method. |
|---|
| 1025 | |
|---|
| 1026 | =head2 $app->handle |
|---|
| 1027 | |
|---|
| 1028 | Wrapper method that determines the proper AtomServer package to pass the |
|---|
| 1029 | request to. |
|---|
| 1030 | |
|---|
| 1031 | =head2 $app->iso2ts($iso_ts, $target_zone) |
|---|
| 1032 | |
|---|
| 1033 | Converts C<$iso_ts> in the format of an ISO timestamp into a MT-compatible |
|---|
| 1034 | timestamp (YYYYMMDDHHMMSS) for the specified timezone C<$target_zone>. |
|---|
| 1035 | |
|---|
| 1036 | =head2 $app->atom_body |
|---|
| 1037 | |
|---|
| 1038 | Processes the request as Atom content and returns an XML::Atom object. |
|---|
| 1039 | |
|---|
| 1040 | =head2 $app->error($code, $message) |
|---|
| 1041 | |
|---|
| 1042 | Sends the HTTP headers necessary to relay an error. |
|---|
| 1043 | |
|---|
| 1044 | =head2 $app->authenticate() |
|---|
| 1045 | |
|---|
| 1046 | Checks the WSSE authentication with the local MT user database and |
|---|
| 1047 | confirms the user is authorized to access the resources required by |
|---|
| 1048 | the request. |
|---|
| 1049 | |
|---|
| 1050 | =head2 $app->show_error($message) |
|---|
| 1051 | |
|---|
| 1052 | Returns an XML wrapper for the error response. |
|---|
| 1053 | |
|---|
| 1054 | =head2 $app->auth_failure($code, $message) |
|---|
| 1055 | |
|---|
| 1056 | Handles the response in the event of an authentication failure. |

| 1067 | $original_entry will have an unassigned 'id'. This callback is executed |
|---|
| 1068 | as a filter, so your handler must return 1 to allow the entry to be saved. |
