MongoDB\Driver\ServerApi::V1
-
Server API version 1.
Beispiele
Beispiel #1 Declare an API version on a manager
<?php
use MongoDB\Driver\Manager;
use MongoDB\Driver\ServerApi;
$v1 = new ServerApi(ServerApi::v1);
$manager = new Manager('mongodb://localhost:27017', [], ['serverApi' => $v1]);
$command = new MongoDB\Driver\Command(['buildInfo' => 1]);
try {
$cursor = $manager->executeCommand('admin', $command);
} catch(MongoDB\Driver\Exception $e) {
echo $e->getMessage(), "\n";
exit;
}
/* The buildInfo command returns a single result document, so we need to access
* the first result in the cursor. */
$buildInfo = $cursor->toArray()[0];
echo $buildInfo->version, "\n";
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
4.9.0-alpha7-49-gb968ca0
Beispiel #2 Declare a strict API version on a manager
The following example sets the strict
flag, which
tells the server to reject any command that is not part of the declared API
version. This results in an error when running the buildInfo command.
<?php
use MongoDB\Driver\Manager;
use MongoDB\Driver\ServerApi;
$v1 = new ServerApi(ServerApi::v1, true);
$manager = new Manager('mongodb://localhost:27017', [], ['serverApi' => $v1]);
$command = new MongoDB\Driver\Command(['buildInfo' => 1]);
try {
$cursor = $manager->executeCommand('admin', $command);
} catch(MongoDB\Driver\Exception $e) {
echo $e->getMessage(), "\n";
exit;
}
/* The buildInfo command returns a single result document, so we need to access
* the first result in the cursor. */
$buildInfo = $cursor->toArray()[0];
echo $buildInfo->version, "\n";
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
Provided apiStrict:true, but the command buildInfo is not in API Version 1
