路径"security.firewalls.main.form_login“的无效类型。预期数组，但得到字符串

Question

我在我的symfony项目中得到了这个错误。我的security.yml文件代码在下面。

# To get started with security, check out the documentation:
# https://symfony.com/doc/current/security.html
security:
    encoders:
        AppBundle\Emtity\User:
            algorithm: becrypt

    # https://symfony.com/doc/current/security.html#b-configuring-how-users-are-loaded
    providers:
        db_provider:
            entity:
                class: AppBundle:User
                property: username

    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

您还可以看到我的config.yml文件

imports:
    - { resource: parameters.yml }
    - { resource: security.yml }
    - { resource: services.yml }

# Put parameters here that don't need to change on each machine where the app is deployed

        strict_requirements: ~

# Doctrine Configuration

        dbname: '%database_name%'
        user: '%database_user%'
        password: '%database_password%'
        charset: UTF8
        # if using pdo_sqlite as your database driver:
        #   1. add the path in parameters.yml
        #     e.g. database_path: '%kernel.project_dir%/var/data/data.sqlite'
        #   2. Uncomment database_path in parameters.yml.dist
        #   3. Uncomment next line:
        #path: '%database_path%'

    orm:
        auto_generate_proxy_classes: '%kernel.debug%'
        naming_strategy: doctrine.orm.naming_strategy.underscore
        auto_mapping: true

# Swiftmailer Configuration
swiftmailer:
    transport: '%mailer_transport%'
    host: '%mailer_host%'
    username: '%mailer_user%'
    password: '%mailer_password%'
    spool: { type: memory }

请检查上面的代码，我不知道我的代码中遗漏了什么东西，所以如果有人有任何解决方案，请帮助我。

我想尝试使用security.yml文件在symfony中进行登录。

Answer 1

您的错误是Invalid type for path “security.firewalls.main.form_login”. Expected array, but got string

如果您查看您的security.yml文件，您会得到以下内容：

form_login:
    login_path:login
    check_path:login

您应该添加一个空格以尊重.yml格式：

form_login:
    login_path: login
    check_path: login

希望能帮上忙！
