[大数据]thinkphp5 mongodb Authentication failed

thinkphp5 mongodb Authentication failed 解决办法

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

原因是
/vendor/topthink/think-mongo/src/Connection.php文件中connect方法（大概189行左右）在拼接dns的时候缺少参数

$config['dsn'] = 'mongodb://' . ($config['username'] ? "{$config['username']}" : '') . ($config['password'] ? ":{$config['password']}@" : '') . $config['hostname'] . ($config['hostport'] ? ":{$config['hostport']}" : '');

dns格式是mongodb://username:passwd@localhost:3306/DbName?param1=val1&param2=val2#utf8参数补齐就行了

$config['dsn'] = 'mongodb://' . ($config['username'] ? "{$config['username']}" : '') . ($config['password'] ? ":{$config['password']}@" : '') . $config['hostname'] . ($config['hostport'] ? ":{$config['hostport']}" : '') . "/" . $config['database'] ;
