MongoDB\Driver\WriteResult::getWriteConcernError — Returns any write concern error that occurred
此函数没有参数。
Returns a MongoDB\Driver\WriteConcernError if a write
concern error was encountered during the write operation, and null
otherwise.
Example #1 MongoDB\Driver\WriteResult::getWriteConcernError() example
<?php
$manager = new MongoDB\Driver\Manager("mongodb://rs1.example.com,rs2.example.com/?replicaSet=myReplicaSet");
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['x' => 1]);
$writeConcern = new MongoDB\Driver\WriteConcern(2, 1);
try {
$manager->executeBulkWrite('db.collection', $bulk, $writeConcern);
} catch(MongoDB\Driver\Exception\BulkWriteException $e) {
var_dump($e->getWriteResult()->getWriteConcernError());
}
?>
以上例程的输出类似于：
object(MongoDB\Driver\WriteConcernError)#6 (3) {
["message"]=>
string(33) "waiting for replication timed out"
["code"]=>
int(64)
["info"]=>
object(stdClass)#7 (1) {
["wtimeout"]=>
bool(true)
}
}
