Symfony 登录无效 [英] Symfony Login Not working

问题描述

我正在使用 symfony 2.8，我是 symfony 的新手，我已经实现了登录和注册，注册工作正常但是当我登录时显示此错误

I'm using symfony 2.8, I'm new to symfony,I have implemented login and registration, registration is working fine but when I login it showing this error

Type error: Argument 4 passed to Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken::__construct() must be of the type array, string given, 
called in C:\xampp\htdocs\blog\vendor\symfony\symfony\src\Symfony\Component\Security\Core\Authentication\Provider\UserAuthenticationProvider.php on line 96

现在我对 ROLES 实现有点困惑，我在数据库中有用户表，

Now I'm bit confused in ROLES implementation, I have users table in DB,

用户表

id      Primary     int(11)
name                varchar(255)    
email   Index       varchar(255) 
password            varchar(64)
roles               varchar(255) 
created_at          datetime 

用户实体

public function setRoles($roles) {
    $this->roles = $roles;
}

public function getRoles() {
        return $this->roles;
}

Security.yml防火墙部分

firewalls:
    # disables authentication for assets and the profiler, adapt it according to your needs
    dev:
        pattern: ^/(_(profiler|wdt)|css|images|js)/
        security: false

    main:
        anonymous: ~
        form_login:
            login_path: login
            check_path: login
        pattern:    ^/
        http_basic: ~
        provider: our_db_provider
        # activate different ways to authenticate

        # https://symfony.com/doc/current/security.html#a-configuring-how-your-users-will-authenticate
        #http_basic: ~

        # https://symfony.com/doc/current/security/form_login_setup.html
        #form_login: ~
        logout:
            path: /logout
            target: /

如果我改变我的 getRoles 函数来返回这样的数组

If I change my getRoles function to return array like this

public function getRoles() {
    return array('ROLE_USER');
}

在这种情况下，它在注册页面上显示错误.

In this case it is showing error on registration page.

The value of type "array" cannot be converted to a valid array key.

推荐答案

看起来您正在为您的角色传递一个字符串.将其作为数组传递！

Looks like you are passing a string for your role. Pass it as an array!

public function __construct($user, $credentials, $providerKey, array $roles = array())

https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Security/Core/Authentication/Token/UsernamePasswordToken.php#L34

因此，如果角色是 Admin，请尝试传递 array('admin').

So if the role was Admin, try passing array('admin').
