基于Laravel MongoDB的部分实践

原文请看我的好朋友葉蕓榕的博客: laravel与MongoDB 的部分实践

MongoDB客户端安装

Windows 平台安装 MongoDB

PS C:\Program Files\MongoDB\Server\4.0\bin> ./mongo
MongoDB shell version v4.0.1
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 4.0.1
Welcome to the MongoDB shell.
For interactive help, type "help".

Server has startup warnings:

Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).

The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.

To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()

MongoDB扩展安装

这里做下补充, 在windows环境下开发需要安装mongodb的扩展

• 首先, php -m 查看是否已有mongodb的扩展

• 其次, php -v 查看环境的版本

$ php -v
PHP 7.2.1 (cli) (built: Jan  4 2018 04:28:54) ( NTS MSVC15 (Visual C++ 2017) x86
 )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2017 Zend Technologies

• 下载对应版本的mongodb扩展

https://pecl.php.net/package/mongodb/1.5.2/windows

Laravel链接MongoDB

• 先在项目目录下运行如下代码

composer require jenssegers/mongodb

• 在配置信息中添加如下信息:

  • config.php/app.php 下的 providers 添加:

    Jenssegers\Mongodb\MongodbServiceProvider::class,

  • config.php/app.php 下的 aliases 添加:

    'Mongo' => Jenssegers\Mongodb\MongodbServiceProvider::class,
    'MoEloquent' => Jenssegers\Mongodb\Eloquent\Model::class,

  • config.php/database.php 中的 connections 添加:

    'mongodb' => [
        'driver'   => 'mongodb',
        'host'     => env('MONGO_HOST', 'localhost'),
        'port'     => env('MONGO_PORT', '27017'),
        'database' => env('MONGO_DATABASE', 'test_mongo'),
        'username' => env('MONGO_USERNAME', 'root'),
        'password' => env('MONGO_PASSWORD', 'root'),
        'strict'   => false,
    ],

  • 在 .env中添加:

    MONGO_HOST=127.0.0.1
    MONGO_PORT=27017
    MONGO_database=test_mongo
    MONGO_USERNAME=
    MONGO_PASSWORD=

添加测试路由

• 在 routes/web.php 中添加:

Route::get('/test_mongo','TestMongoDBController@testMongo');

添加测试Model

• app\Models\MongoDB.php

<?php

namespace App\Models;

# 已经在aliases添加即可不用下面这么
# use Jenssegers\Mongodb\Eloquent\Model as MoEloquent;
use Illuminate\Support\Facades\DB;

class MongoDB extends MoEloquent
{
    protected $connection = "mongodb";
    protected $collection = "test_mongo";
}

添加测试控制器

• app\Http\Controllers\TestMongoDBController

<?php

namespace App\Http\Controllers;

use App\Models\MongoDB;

class TestMongoDBController extends Controller
{
    public function testMongo()
    {
        dd($this->testUpdate());
    }

    public function testAdd()
    {
        $mongo = new MongoDB();

        $mongo->name = 'test_name_1';
        $mongo->info = 'test_info_1';

        $res = $mongo->save();

        return $res ? '插入成功' : '插入失败';
    }

    public function testDel()
    {
        // 删除指定id
        $res = MongoDB::destroy('5b75205aa8ce413058001c42');

        return $res ? '删除成功' : '删除失败';
    }

    public function testUpdate()
    {
        $info = MongoDB::where('_id', '=', '5b752088a8ce413058001c43')->first();
        $info->info = '更新后的信息';
        $res = $info->save();

        return $res ? '更新成功' : '更新失败';
    }
}
