PHP5 PHP7 用原生代码连接mongodb，有密码认证

今天药忘吃喽~ 2021-12-10 15:02 344阅读 0赞

**前提**  
Win7上测试。PHP5需要安装php\_mongo.dll 而PHP7安装的是php\_mongodb.dll扩展  
各个扩展：

*  php5.6.40 TS VC11 - mongo1.6.16 - mongodb1.6.10
 *  php7.3.5 TS VC15 - mongodb 1.5.5

**创建用户**  
在shell中执行创建mongo用户

> use test
    switched to db test
    > db.createUser({ 
    	user: "test1",
    	pwd: "test1",
    	roles: [
    		{  role: "readWrite", db: "test" },
    		{  role: "read", db: "reporting" }
    	]
    	});
    	
    Successfully added user: { 
            "user" : "test1",
            "roles" : [
                    { 
                            "role" : "readWrite",
                            "db" : "test"
                    },
                    { 
                            "role" : "read",
                            "db" : "reporting"
                    }
            ]
    }
    >
    > show users;
    { 
            "_id" : "test.test1",
            "userId" : UUID("406cb77c-1fc0-4f34-a257-1c975349533a"),
            "user" : "test1",
            "db" : "test",
            "roles" : [
                    { 
                            "role" : "readWrite",
                            "db" : "test"
                    },
                    { 
                            "role" : "read",
                            "db" : "reporting"
                    }
            ],
            "mechanisms" : [
                    "SCRAM-SHA-1",
                    "SCRAM-SHA-256"
            ]
    }
    >
    > db.auth('test1','test1')
    1
    > db
    test

**测试代码**  
文件 E:/test/mongo.php

<?php
    
    $config = [
        'username' => 'test1',
        'password' => 'test1',
        'auth_db' => 'test',
        'host' => '127.0.0.1',
        'port' => '27017',
        'db' => 'test',
        'table' => 'foo',
        // 'db' => 'reporting',
        // 'table' => 'foo2',
    ];
    
    $result = null;
    if (PHP_VERSION_ID < 70000) { 
        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'],
            ));
    
            $db = $conn->selectDB($config['db']);
            $mongo = $db->selectCollection($config['table']);
            $result = $mongo->findOne();
        } catch (Exception $e) { 
            var_dump($e->getMessage());
        }
    } else { 
    
    
    // $manager = new MongoDB\Driver\Manager("mongodb://" . $config['username'] . ":" . $config['password'] . "@" . $config['host'] . ":" . $config['port'].'/'.$config['auth_db']);
        $manager = new MongoDB\Driver\Manager("mongodb://" . $config['host'] . ":" . $config['port'] . '/' . $config['auth_db'], [
            'username' => $config['username'],
            'password' => $config['password'],
            'db' => $config['auth_db']
        ]);
    
        $filter = [];
        $options = [];
        $query = new MongoDB\Driver\Query($filter, $options); //查询请求
    
        var_dump($config['db'] . "." . $config['table']);
    
        try { 
            $result = $manager->executeQuery($config['db'] . "." . $config['table'], $query)->toArray();
        } catch (Exception $e) { 
            var_dump($e->getMessage());
        }
    }
    
    var_dump($result);

**输出**  
php5.6

D:\>d:/php56/php.exe e:/test/mongo.php
    array(3) {
      ["_id"]=>
      object(MongoId)#6 (1) {
        ["$id"]=>
        string(24) "5d26ba7b1ed45d92904eb3d5"
      }
      ["x"]=>
      float(1)
      ["y"]=>
      float(1)
    }
    
    D:\>

但PHP5.6有一个问题，如果是切换到非认证数据库 reporting，无法访问，报错提示：`Authentication failed`。

D:\>d:/php56/php.exe e:/test/mongo.php
    string(113) "Failed to connect to: 127.0.0.1:27017: SASL Authentication failed o
    n database 'reporting': Authentication failed."
    NULL
    
    D:\>

可问题是我用终端和no sql 工具，比如No SQL Manager For MongoDB 都没有问题。  
都可以访问，如下图。如果你知道这个问题的原因，希望能联系我 [coconets@163.com][coconets_163.com]
