Question

尝试在Symfony2中实现基于角色的用户访问，但不知何故Symfony2不从数据库中获取用户。我得到的只是Bad Credentials错误。当我尝试以内存用户身份登录时 - 它工作正常。我错过了什么吗？

我的security.yml

     * @return string The role.
     */
    public function getRole()
    {
        return $this->getName();
    }
}

我的SecurityController

<?php

namespace Web20\CMSBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\Security\Core\SecurityContext;
use Web20\CMSBundle\Entity\Category;

class SecurityController extends Controller

}

我的用户实体

<?php

    /**

    public function setUsername($value)
    {

    }

    /**

     */
    public function setFirstName($value)
    {
        $this->firstName = $value;
    }

    /**

     */
    public function setLastName($value)
    {
        $this->lastName = $value;
    }

     */
    public function setEmail($value)
    {
        $this->email = $value;
    }       

    /**

    public function getPassword()
    {
        return $this->password;
    }

    public function setPassword($value)
    {
        $this->password = $value;
    }

    /**
     * @return string The salt.
     */
    public function getSalt()
    {
        return $this->salt;
    }

    /**
     * @param string $value The salt.
     */
    public function setSalt($value)
    {
        $this->salt = $value;
    }

    /**
     * @return ArrayCollection A Doctrine ArrayCollection
     */
    public function getUserRoles()
    {
        return $this->userRoles;
    }

    /**
     * Constructs a new instance of User
     */
    public function __construct()
    {
        $this->userRoles = new ArrayCollection();
        $this->createdAt = new \DateTime();
    }

    /**
     * Erases the user credentials.
     */
    public function eraseCredentials()
    {

    }

    /**
     * @return array An array of Role objects
     */
    public function getRoles()
    {
        return $this->getUserRoles()->toArray();
    }

    /**
     * Compares this user to another to determine if they are the same.
     * 
     * @param UserInterface $user The user
     * @return boolean True if equal, false othwerwise.
     */
    public function equals(UserInterface $user)
    {
        return md5($this->getUsername()) == md5($user->getUsername());
    } 
}

login.html.twig的重要部分如下：

        <label for="_username">Username:</label>
            <input type="text" name="_username" id="username" value="{{ last_username }}"/>
        <label for="_password">Password:</label>
            <input type="password" name="_password" id="password"/>

虽然用户是这样创建的：

    $role = new Role();
    $role->setName('ROLE_ADMIN');

    $role1 = new Role();
    $role1->setName('ROLE_CUSTOMER');


$role2 = new Role();
$role2->setName('ROLE_SALESMAN');       

$role3 = new Role();
$role3->setName('ROLE_CONTENT_ADMIN');              

$manager->persist($role); 
    $manager->persist($role1); 
    $manager->persist($role2); 
    $manager->persist($role3); 

$user = new User();
$user->setFirstName('FirstName');
$user->setLastName('LastName');
$user->setEmail('lulz@roflmao.com');
$user->setUsername('admin');
$user->setSalt(md5(time()));

$encoder = new MessageDigestPasswordEncoder('sha512', true, 3);
$password = $encoder->encodePassword('admin', $user->getSalt());
$user->setPassword($password);

$user->getUserRoles()->add($role);


    $manager->persist($user);
$manager->flush();

Answer 1

我没有时间检查所有代码，但我看到两件事： 1）您的用户'用户'将无法登录，因为您给了他一个密码：'userpass'，尽管您已将密码设置为sha512编码的3倍，然后是base64编码。您应该对密码进行编码，然后使用设置文件中的编码。 2）我遇到'encode-as-base64：true'的问题。如果您在修复第一个问题后无法登录，请尝试使用'encode-as-base64：false'。当然，这次你必须提供未编码为base64的密码。

希望这有帮助。
