Question

我尝试通过将email和password作为参数传递给/ api / v1 / sign_in来验证Rails v.4.2.2应用程序，从而尝试通过API进行身份验证。我使用邮递员提出请求。

这是我将请求发送到服务器时收到的错误：

Started POST "/api/v1/users/sign_in" for 127.0.0.1 at 2015-09-25 20:46:31 +0530
Processing by Api::V1::SessionsController#create as */*
  Parameters: {"user"=>{"email"=>"example@example.com", "password"=>"[FILTERED]"}}

我在app / controllers / api / v1 / sessions_controller.rb的代码中从params.require收到错误：

class Api::V1::SessionsController < Api::V1::BaseController
  skip_before_action :authenticate_user_from_token!
  before_action :ensure_params_exist
  respond_to :json

  def create
    @user = User.find_for_database_authentication(email: user_params[:email])
    return invalid_login_attempt unless @user
    return invalid_login_attempt unless @user.valid_password?(user_params[:password])
    @auth_token = jwt_token(@user)
  end

  private

  def user_params
    params.require(:user).permit(:email, :password)
  end

  def ensure_params_exist
    if user_params[:email].blank? || user_params[:password].blank?
      return render_unauthorized errors: { unauthenticated: ["Incomplete credentials"] }
    end
  end

  def invalid_login_attempt
    render_unauthorized errors: { unauthenticated: ["Invalid credentials"] }
  end
end

对于raise params.inspect，我收到以下回复：

{"------WebKitFormBoundaryJogEDEbfqWmnfhSL\r\nContent-Disposition: form-data; name=\"user[email]\"\r\n\r\example@example.com\r\n------WebKitFormBoundaryJogEDEbfqWmnfhSL\r\nContent-Disposition: form-data; name=\"user[password]\"\r\n\r\password\r\n------WebKitFormBoundaryJogEDEbfqWmnfhSL--\r\n"=>nil}

我被params.require卡住了好几个小时，我无法弄清楚确切的问题。有谁知道这个问题？
