php - Codeigniter 不工作 MongoDB 连接

Question

我正在使用 Codeigniter MVC。我安装了 MongoDB，但它不起作用。

我遇到了这个错误；

无法连接到 MongoDB:无法连接到:localhost:27017:数据库“teknikserviscim”上的 SASL 身份验证失败:身份验证失败。

配置文件是这样的；

$config['mongo_db']['active'] = 'newdb';    
$config['mongo_db']['newdb']['hostname'] = 'localhost';    
$config['mongo_db']['newdb']['port']     = '27017';    
$config['mongo_db']['newdb']['username'] = 'superuser';    
$config['mongo_db']['newdb']['password'] = '12345678';    
$config['mongo_db']['newdb']['database'] = 'teknikserviscim';    
$config['mongo_db']['newdb']['db_debug'] = TRUE;    
$config['mongo_db']['newdb']['write_concerns'] = (int)1;    
$config['mongo_db']['newdb']['journal'] = TRUE;    
$config['mongo_db']['newdb']['read_preference'] = NULL;
$config['mongo_db']['newdb']['read_preference_tags'] = NULL;


class PanelHesap extends CI_Model {

public function __construct()
{
    parent::__construct();
    $this->load->library('mongo_db', array('activate'=>'newdb'),'mongo_db2');       
}

嗯。问题是什么 ？谢谢。

你的数据库连接应该是

$config['mongo_db']['active'] = 'default';
$config['mongo_db']['default']['no_auth'] = FALSE;
$config['mongo_db']['default']['hostname'] = 'localhost';
$config['mongo_db']['default']['port'] = '27017';
$config['mongo_db']['default']['username'] = 'admin';
$config['mongo_db']['default']['password'] = '123456';
$config['mongo_db']['default']['database'] = 'mydatabase';
$config['mongo_db']['default']['db_debug'] = TRUE;
$config['mongo_db']['default']['return_as'] = 'array';
$config['mongo_db']['default']['write_concerns'] = (int)1;
$config['mongo_db']['default']['journal'] = TRUE;
$config['mongo_db']['default']['read_preference'] = NULL;
$config['mongo_db']['default']['read_preference_tags'] = NULL;
$config['mongo_db']['default']['no_auth'] = FALSE;

在 application/libraries 添加这个库

GIT Hub

并且在 autoload.php

$autoload['libraries'] = array('Mongo_db');

插入、更新、删除示例
