權限

已經開啟，在test上創建了用戶test1，并賦予了 test的readWrite 和 reporting的read權限。

{

"_id" : "test.test1",

"userId" : UUID("406cb77c-1fc0-4f34-a257-1c975349552a"),

"user" : "test1",

"db" : "test",

"roles" : [

{

"role" : "readWrite",

"db" : "test"

},

{

"role" : "read",

"db" : "reporting"

}

],

"mechanisms" : [

"SCRAM-SHA-1",

"SCRAM-SHA-256"

]

}

使用CLI模式進行連接，mongo -u test1 -p –authenticationDatabase test 可以進入，show dbs會顯示兩個庫。

D:\>mongo -u test1 -p --authenticationDatabase test

MongoDB shell version v4.0.10

Enter password:

connecting to: mongodb://127.0.0.1:27017/?authSource=test&gssapiServiceName=mong

odb

Implicit session: session { "id" : UUID("b0e13217-63b3-454b-b8fc-32dd24fbfd1d")

}

MongoDB server version: 4.0.10

> show dbs

reporting ?0.000GB

test ? ? ? 0.000GB

> use reporting

switched to db reporting

> show collections

foo2

>

問題

但使用PHP連接mongodb，卻只能在test庫上操作，無法連接到 reporting 庫。可在cli模式是可以。

$config = [

'username' => 'test1',

'password' => 'test1',

'auth_db' => 'test',

'host' => '127.0.0.1',

'port' => '27017',

'db' => 'reporting',

'table' => 'foo2',

];

try {

$conn = new MongoClient("mongodb://" . $config['username'] . ':' . $config['password'] . '@' . $config['host'] . ':' . $config['port'] . '/' . $config['auth_db']);

// ? ? ? ?$conn = new MongoClient("mongodb://" . $config['host'], array(

// ? ? ? ? ? ?'username' => $config['username'],

// ? ? ? ? ? ?'password' => $config['password'],

// ? ? ? ? ? ?'db' => $config['auth_db']

// ? ? ? ?));

$dbs = $conn->selectDB($config['db']);

$mongo = $dbs->selectCollection($config['table']);

$row = $mongo->findOne();

} catch (Exception $e) {

var_dump($e->getMessage());

}

報錯內容

string(113) "Failed to connect to: 127.0.0.1:27017: SASL Authentication failed o

n database 'reporting': Authentication failed."

可問題是 test1用戶對 reporting也有read權限啊，而且在 cli模式是完全可以列出和操作。
