MongoDB和Phalcon

Question

我正在尝试将mongoDB与phalcon框架连接起来。我的代码如下：

index.php文件

<?php

if ($handle = opendir('include/models')) {
    while (false !== ($entry = readdir($handle))) {
        if (preg_match('/\.php$/', $entry)) {
            require_once "include/models/$entry";
        }
    }
    closedir($handle);    
}

require 'vendor/autoload.php';
use Phalcon\DI\FactoryDefault;
use Phalcon\Mvc\Model;

$app = new Phalcon\Mvc\Micro();
$di = new \Phalcon\DI\FactoryDefault();
$config = new Phalcon\Config\Adapter\Ini('include/config/config.ini');

// Simple database connection to localhost
$di->set('mongo', function() {
    $manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
    return $manager->selectDb("MyApi");
},true);

$di->set('collectionManager', function () {
    return new Phalcon\Mvc\Collection\Manager();
});
$app->setDI($di);


$directory = new User_detail();


 $app->get('/userdetail/{code}', function ($code) use ($app,$directory) {
   $directory->getUser($app,$code);
  });

 $app->notFound(function () use ($app) {
   $app->response->setStatusCode(424, "Method Failed")->sendHeaders();
   echo json_encode(array('status' => 'ERROR', 'messages' => "Method Failed"));
});
$app->handle();
?>

模型文件User_detail.php

<?php
use Phalcon\Mvc\Collection;
use Phalcon\Mvc\Model;
use MongoDB\Driver\Manager;
use Phalcon\Mvc\Micro;
use Phalcon\Db\Column;

class User_detail extends Collection
{

    public function initialize()
    {
        $this->setSource("User");
    }

    function getUser($app,$code)
    {
            $robot = User_detail::findFirst(
                [
                    [
                        "Name" => "android",
                    ]
                ]
            );

            echo $robot->Name; die;

    }
}
?> 

我的错误就像

错误:调用index.php中未定义的方法MongoDB\Driver\Manager::selectDb()

有什么问题吗？

Answer 1

首先，我使用composer将Phalcon孵化器安装到我的供应商目录中：

composer require phalcon/incubator

然后，我确保加载了供应商库：

include_once SITE_ROOT . 'vendor/autoload.php';

然后我使用在vendor/phalcon/incubator/Library/Phalcon/Db/Adapter/MongoDB/Client.php中找到的\Phalcon\Db\Adapter\MongoDB\Client()

在services.php中：

$di->setShared('mongo', function () use ($config) {
    $mongo = new \Phalcon\Db\Adapter\MongoDB\Client();
    return $mongo->selectDatabase($config->mongodb->dbname);
});

然后确保我的(vendor/phalcon/incubator/Library/Phalcon/Mvc/MongoCollection.php).扩展\ MongoCollection \Mvc\MongoCollection MongoCollection

模型/MyCollectionStats.php Stats.php：

<?php

namespace Common\Models;

class MyCollectionStats extends \Phalcon\Mvc\MongoCollection
{...

对于php7，您需要使用MongoCollection和孵化器中的其他相关类。
