zabbix 添加主机成功失败判断

zabbix 成功添加后:

$VAR1 = bless( {
                 'version' => 0,
                 'content' => {
                                'jsonrpc' => '2.0',
                                'id' => 1,
                                'result' => {
                                              'hostids' => [
                                                             '10228'
                                                           ]
                                            }
                              },
                 'jsontext' => '{"jsonrpc":"2.0","result":{"hostids":["10228"]},"id":1}',
                 'is_success' => 1
               }, 'JSON::RPC::ReturnObject' );
----------------------
HASH(0x2857fd0)

zabbix 添加是失败的情况:

$VAR1 = bless( {
                 'version' => 0,
                 'content' => {
                                'jsonrpc' => '2.0',
                                'error' => {
                                             'data' => 'Host with the same name "zjtest9-app" already exists.',
                                             'message' => 'Invalid params.',
                                             'code' => -32602
                                           },
                                'id' => 1
                              },
                 'jsontext' => '{"jsonrpc":"2.0","error":{"code":-32602,"message":"Invalid params.","data":"Host with the same name \\"zjtest9-app\\" already exists."},"id":1}',
                 'is_success' => 0
               }, 'JSON::RPC::ReturnObject' );

通过判断:
die "host.get failed\n" unless $response->content->{error}->{data};
