MongoDB\Driver\ServerApi::V1Server API version 1.
示例 #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";
?>以上示例会输出：
4.9.0-alpha7-49-gb968ca0
示例 #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";
?>以上示例会输出：
Provided apiStrict:true, but the command buildInfo is not in API Version 1
