Question

我找到了一些关于可恢复功能的讨论和主题，但无法解决我遇到的问题。

我有一个使用rails 3.2后端的前端API（使用Devise 2.2.4）所有路线都运行良好但是当我尝试更新密码时，它会发送一个json共鸣（在邮递员中）：

"reset_password_token" : "can't be blank"

如果我理解这个功能：

1- POST＃POST / resource / password将重置密码发送到电子邮件（用作参数） 2-然后我执行GET /资源/密码/编辑？reset_password_token = abcdef，它带有密码输入进入我的FrontEnd页面。 3-密码更改后我启动#PUT /资源/密码

这是发生错误的地方。

这是password_controller.rb文件：

class Devise::PasswordsController < DeviseController
  prepend_before_filter :require_no_authentication
  # Render the #edit only if coming from a reset password email link
  append_before_filter :assert_reset_token_passed, :only => [:edit, :update]

# GET /resource/password/new
def new
  build_resource({})
end

# POST /resource/password
def create
  self.resource = resource_class.send_reset_password_instructions(resource_params)

  if successfully_sent?(resource)
    #respond_with({}, :location => after_sending_reset_password_instructions_path_for(resource_name))
    render json: { message: "mail sent"}, status: 200
  else
    #respond_with(resource)
    render json: { :status }
  end
 end

 # GET /resource/password/edit?reset_password_token=abcdef
 def edit
  self.resource = resource_class.new
  resource.reset_password_token = params[:reset_password_token]
 end

 # PUT /resource/password
 def update
  self.resource = resource_class.reset_password_by_token(params[:reset_password_token])
  if resource.errors.empty?
  resource.unlock_access! if unlockable?(resource)
  flash_message = resource.active_for_authentication? ? :updated : :updated_not_active
  set_flash_message(:notice, flash_message) if is_navigational_format?
  #sign_in(resource_name, resource)
  #respond_with resource, :location => after_resetting_password_path_for(resource)
  render json: { message: "password updated"}, status: 200
 else
  respond_with resource
 end
end

protected
 def after_resetting_password_path_for(resource)
  after_sign_in_path_for(resource)
 end

# The path used after sending reset password instructions
def after_sending_reset_password_instructions_path_for(resource_name)
  new_session_path(resource_name) if is_navigational_format?
end

# Check if a reset_password_token is provided in the request
def assert_reset_token_passed
  if params[:reset_password_token].blank?
    #set_flash_message(:error, :no_token)
    #redirect_to new_session_path(resource_name)
    render json: { message: "reset password is not blank"}, status: 200
  end
end

# Check if proper Lockable module methods are present & unlock strategy
# allows to unlock resource on password reset
def unlockable?(resource)
  resource.respond_to?(:unlock_access!) &&
    resource.respond_to?(:unlock_strategy_enabled?) &&
    resource.unlock_strategy_enabled?(:email)
end
end

recoverable.rb方法reset_password_by_token：

   def reset_password_by_token(attributes={})
      recoverable = find_or_initialize_with_error_by(:reset_password_token, attributes[:reset_password_token])
      if recoverable.persisted?
        if recoverable.reset_password_period_valid?
          recoverable.reset_password!(attributes[:password], attributes[:password_confirmation])
      else
        recoverable.errors.add(:reset_password_token, :expired)
      end
    end
    recoverable
  end

  Devise::Models.config(self, :reset_password_keys, :reset_password_within)

我试图在方法上添加一些放置，但它们不会在积压中抛出。这是我的rails日志：

修改的

===================

要了解请求的来源，我在Angular / FrontEnd部分的PUT请求下面添加：

  users.newPassword = function (token, password) {
    var putData = {
     user:{
       reset_password_token: token,
       password: password
     }
  };
  return Restangular.withConfig(function(RestangularConfigurer) {
    RestangularConfigurer.setFullResponse(true);
    }).one('/users/password').customPUT(putData);
  };

Answer 1

您将 reset_password_by_token 声明为类方法。没关系。但是您没有将资源对象或reset_password_token 作为方法的参数传递。这意味着不要设置resent_token。

您可以调试并检查资源是否设置了reset_password_token。如果是，请按照以下

self.resource = resource_class.reset_password_by_token(params[:confirmation_token])

所以，要么使用

resource.reset_password_by_token(params[:password])

或

resource_class.reset_password_by_token(params[:password], params[:reset_password_token])

Answer 2

我终于找到了解决办法。事实上，Devise正在将params作为用户Array等待。我直接发送了reset_password_token，但是Devise正在等待user[reset_password_token] .....

生成的令牌也不是好的。在我的邮件模板中，我有：

You asked to <%= link_to 'reset your password', edit_password_url(@resource, reset_password_token: @resource.reset_password_token %>.

我将其修改为

You asked to <%= link_to 'reset your password', edit_password_url(@resource, reset_password_token: @token %>.

设计（通过API）可恢复：reset_password_token不能为空
