[MongoDB] laravel7链接mongoDb

• 1.需要使用composer安装第三方包,看前面的文章, 然后打开config/databases.php

 'connections' => [

        // ...  
        'mongodb' => [
            'driver' => 'mongodb',
            'host' => 'localhost',
            'port' => '端口',
            'database' => '',
            'username' => '账号',
            'password' => '密码',
            'options' => [
                'database' => '默认数据库'
            ]
        ],

    ],

• 2.使用

        $mongo = DB::connection('mongodb');
        $res = $mongo->collection('daily_stock')->get();

        $insert = [
            'goods_id'  => 1,
            'num'       => 5
        ];

        $res = $mongo->collection('集合名')->insert($insert);
