symfony5初体验

先,放个目录:

1、配置mysql

2、通过symfony的security实现用mysql用户表登录

3、easyAdmin bundle创建的用户记录密码没加密的问题


之前用symfony3.4一直感觉他太重了,最上手symfony5发现加入了很多新特性,搭配easyadminBundle、api-platform这些用起来感觉简直如有神助,瞬间爱了。

不过api-platform还没太弄明白,有用这个的可以给分享下文档,官网的文档说的太简略了。|||

下面记一些使用时遇到的小问题:

ps:安装直接按官网文档composer就行,这里就跳过了;

1、配置mysql

文档说配置到 /config/doctrine.yml

实际上doctrine.yml又读取了根目录下的.env文件的DATABASE_URL的值,所以可以直接对.env的DATABASE_URL配置。

# DATABASE_URL=mysql://username:[email protected]:3306/dbname?serverVersion=5.7 我的数据库没有密码,所以:后面直接跟了@ip:port
DATABASE_URL=mysql://root:@127.0.0.1:3306/fbm?serverVersion=5.7

2、通过symfony的security实现用mysql用户表登录

先说步骤,后面依次细说:

  1. 创建user entity类并实现UserInterface并把它更新到数据库(可以使用命令:php bin/console make:entity)
  2. 把user类配置为用户提供者,并配置密码加密算法
  3. 创建防火墙认证器(用于登录验证等… 使用命令:php bin/console make:auth)
  4. 给数据库的user表添加用户
  5. 测试登录

1、依次执行:

php bin/console make:entity # 创建enity并根据提示添加usernam、password、roles、salt等字段 
# tips:roles建议array类型 

php bin/console doctrine:schema:update  --force --dump-sql  #把enity更新到数据库

2、在config/package/security.yml的security添加如下配置:

    providers:
        users_in_memory: { memory: null }
        users:
            entity:
                # 这个entity类用来提供用户
                class: 'App\Entity\User'
                # the property to query by - e.g. username, email, etc
                property: 'username'

    encoders:
        # use your user class name here
        App\Entity\User:
            # Use native password encoder 配置密码加密算法
            # This value auto-selects the best possible hashing algorithm
            # (i.e. Sodium when available).
            algorithm: sha256
            encode_as_base64: true
            iterations: 1  # 循环次数

3、执行如下命令创建验证器:


 php bin/console make:auth

# 以下是输出内容,根据提示按实际情况填写就好。。。

 What style of authentication do you want? [Empty authenticator]:
  [0] Empty authenticator
  [1] Login form authenticator
 > 1
1[K

 The class name of the authenticator to create (e.g. AppCustomAuthenticator):
 > LoginFormAuthenticator  #### 验证器类名

 Choose a name for the controller class (e.g. SecurityController) [SecurityController]:
 >

 Enter the User class that you want to authenticate (e.g. App\Entity\User) [App\Entity\Us
 >

 Which field on your App\Entity\User class will people enter when logging in? [username]:
  [0] id
  [1] username
  [2] email
  [3] password
  [4] roles
  [5] salt
  [6] created_at
  [7] updated_at
 >


 Do you want to generate a '/logout' URL? (yes/no) [yes]:
 >

 created: src/Security/LoginFormAuthenticator.php
 updated: config/packages/security.yaml
 created: src/Controller/SecurityController.php
 created: templates/security/login.html.twig


  Success!


 Next:
 - Customize your new authenticator.
 - Finish the redirect "TODO" in the App\Security\LoginFormA
 - Check the user's password in App\Security\LoginFormAuthen
 - Review & adapt the login template: templates/security/log

修改验证器类的checkCredentials方法为:

// src/Security/LoginFormAuthenticator.php

    public function checkCredentials($credentials, UserInterface $user)
    {
        return $this->passwordEncoder->isPasswordValid($user, $credentials['password']);
    }

其他两部就不细说了。

3、easyAdmin bundle创建的用户记录密码没加密的问题

要解决这个问题--- more》,可以:

  1.   改写user entity的setPassword方法为(github的大佬说这种方法破环了封装,我:挺适合我|||):

    
        public function setPassword(string $password): self
        {
            global $kernel;
            if (method_exists($kernel, 'getKernel'))
                $kernel = $kernel->getKernel();
            $this->password = $kernel->getContainer()->get('security.password_encoder')->encodePassword($this, $password);
            return $this;
        }
  2. 或者实现AdminController和如下关键的几个方法,并且将config/route/easy_admin.yml做如下配置:
easy_admin_bundle:
    resource: 'App\Controller\AdminController'
    prefix: /admin
    type: annotation
<?php
/*
 * @Author: l.jirong [email protected]
 * @Date: 2020-03-07 09:55:18
 * @LastEditors: l-jirong [email protected]
 * @LastEditTime: 2020-03-08 00:13:44
 * @Description: file content
 */
namespace App\Controller;

use App\Entity\User;
use Symfony\Component\Security\Core\Encoder\EncoderFactory;
use Symfony\Component\Security\Core\Encoder\MessageDigestPasswordEncoder;
use EasyCorp\Bundle\EasyAdminBundle\Controller\EasyAdminController;
use Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface;

class AdminController extends EasyAdminController
{
    protected function persistUserEntity($user)
    {
        $encodedPassword = $this->encodePassword($user, $user->getPassword());
        $user->setPassword($encodedPassword);

        parent::persistEntity($user);
    }

    protected function updateUserEntity($user)
    {
        $encodedPassword = $this->encodePassword($user, $user->getPassword());
        $user->setPassword($encodedPassword);

        parent::updateEntity($user);
    }

    private function encodePassword($user, $password)
    {
        $passwordEncoderFactory = new EncoderFactory([
            // 这里的sha256以及后面的参数要和security.yml里的配置相同,否则加密后登录验证通不过
            User::class => new MessageDigestPasswordEncoder('sha256',true,1)
        ]);

        $encoder = $passwordEncoderFactory->getEncoder($user);

        return $encoder->encodePassword($password, $user->getSalt());
    }

}

3、文件上传,从请求对象中获取文件和文件名等信息

//文档: https://symfony.com/doc/current/controller/upload_file.html

$this->request->files->get('imageresource');  // imageresource entity类名(小写)

// 获取文件名: ->getClientOriginalName()

这些都是经过好几天的时间摸索出来的 : ( 。。|||,当然,搜索引擎帮了很多忙。)
