预定义常量

MongoDB\Driver\ServerApi::V1

Server API version 1.

示例

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
