我在Angular上有应用程序，它使用服务器RubyonRails/oAuth后端。在控制台中注册用户时，我会收到这些错误。
POST*.herokuapp.com/api/users 500 (Internal Server Error) *.herokuapp.com/api/users:1
Failed to load *.herokuapp.com/api/users: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin '*.herokuapp.com' is therefore not allowed access. The response had HTTP status code 500. /registration:1
{
"isTrusted": true /auth.ts:95
}
以及发生的其他错误
{"error":"invalid_grant","error_description":"The provided authorization grant is invalid, expired, revoked, does not match the redirection URI used in the authorization request, or was issued to another client."}
Error: Uncaught (in promise): {"error":"invalid_grant","error_description":"The provided authorization grant is invalid, expired, revoked, does not match the redirection URI used in the authorization request, or was issued to another client."}
这是我的应用程序.rb
require_relative 'boot'
require 'rails/all'
# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)
module Dkeeper
class Application < Rails::Application
config.middleware.use Rack::Cors do
allow do
origins '*'
resource '*', headers: :any, methods: [:get, :post, :put, :patch, :delete, :options, :head]
end
end
end
end
此处为user_controller.rb
class Api::UsersController < ApiController
before_action :find_user, only: [:show, :update, :destroy]
def index
@users = User.all
if @users.count(:all) > 0
render
else
render json: { message: 'No Users Found' }, status: 200
end
end
def show
render
end
def create
@user = User.new(user_params)
if @user.save
origin = request.headers['origin']
ApplicationMailer.registration_confirmation(@user, origin).deliver
render :show, status: :ok
else
render json: {
message: 'Registration failed',
errors: @user.errors.full_messages
}, status: 422
end
end
def update
if @user.update(user_params)
render :show
else
render json: {
message: 'Could not update profile',
errors: @user.errors.full_messages
}, status: 422
end
end
def destroy
if @user.destroy
render
else
render json: {
message: 'Could not delete user',
errors: @user.errors.full_messages
}, status: 422
end
end
def confirm_email
user = User.find_by_confirm_token(params[:id])
if user
user.update_attribute(:email_confirmed, true)
render json: {
message: 'Email address has already confirmed',
errors: user.errors.full_messages
}, status: 200
else
render json: {
message: 'Email confirmation failed'
}, status: 422
end
end
private
def user_params
params.require(:user).permit(:email, :first_name, :last_name, :password, :password_confirmation)
end
def find_user
@user = User.find(params[:id])
end
end
当我登录时，用户被添加到数据库中，但我在控制台中收到一个错误。
谢谢你的帮助。
这是一个CORS错误。您需要在服务器端启用CORS，并在客户端启用正确的标头。也谷歌"同源政策">
