Bulk write failed due to previous MongoDB\Driver\Exception\AuthenticationException: Authentication failed.

这里thinkphp6内置的think-orm已经包含mongo连接了,所以不用单独安装think-mongo（安装后类会冲突导致报错）

1.添加.env配置文件中的配置

[mongo]
HOSTNAME = "127.0.0.1"
AUTH_DATABASE = admin
DATABASE = test
USERNAME = root
PASSWORD = root
HOSTPORT = 27017
CHARSET = utf8
DEBUG = true

2.修改配置文件database.php 添加mongo配置

'mongo' => [
    'type'              => 'mongo',
    'hostname'          => env('mongo.hostname', '127.0.0.1'),
    'database'          => env('mongo.database', ''),//操作数据库
    'auth_database'     => env('mongo.auth_database', env('mongo.database', '')),//授权数据库
    'username'          => env('mongo.username', 'root'),
    'password'          => env('mongo.password', ''),
    'hostport'          => env('mongo.hostport', '27017'),
    'debug'             => env('mongo.debug', true),
    'dsn'               => env('mongo.dsn', ""),
    'schema_cache_path' => app()->getRuntimePath() . 'schema' . DIRECTORY_SEPARATOR,
],

3.修改tp框架底层vendor/topthink/think-orm/src/db/connector/Mongo.php 第100行，将以下代码替换

    /**
     * 架构函数 读取数据库配置信息
     * @access public
     * @param array $config 数据库配置数组
     */
    public function __construct(array $config = [])
    {
        if (!empty($config)) {
            $this->config = array_merge($this->config, $config);
        }
        /**
         * TinyMeng update start
         * DateTime: 2020-04-20 11:15
         */
        if(!empty($this->config['username'])){
            $this->config['params']['username'] = $this->config['username'];
        }
        if(!empty($this->config['password'])){
            $this->config['params']['password'] = $this->config['password'];
        }
        if(!empty($this->config['auth_database'])){
            $this->config['params']['db'] = $this->config['auth_database'];
        }
        /** TinyMeng update start */

        // 创建Builder对象
        $class = $this->getBuilderClass();

        $this->builder = new $class($this);
    }
