由于:ensure_valid_accept_media_type呈现或重定向完成406不可接受错误，筛选器链已停止

Question

我正在使用Rails5构建一个简单的应用程序接口。我遵循了这个视频教程here，它使用了jsonapi-resources gem。我走得更远，使用gem实际设置了一些API安全性。

# Gemfile
source 'https://rubygems.org'

gem 'rails', github: 'rails/rails'
gem 'sqlite3'
gem 'puma'
#gem 'pg'
gem 'jsonapi-resources', '~> 0.7.1.beta2'

# Security
gem 'rack-attack'
gem 'rack-protection'
gem 'secure_headers'
gem 'brakeman'
gem 'rack-cors'

gem 'omniauth'
gem 'omniauth-oauth2'
gem 'devise'
gem 'devise_token_auth', git: 'git://github.com/lynndylanhurley/devise_token_auth.git'
gem 'omniauth-twitter'
gem 'omniauth-facebook'
gem "omniauth-google-oauth2"
gem 'omniauth-github'
gem 'omniauth-twitch'
gem 'omniauth-instagram'

gem 'pundit'
gem 'dynamic_sitemaps'
gem 'faker'

group :development, :test do
  gem 'byebug', platform: :mri
  gem 'better_errors'
end

group :development do
  gem 'listen', '~> 3.0.5'
  gem 'spring'
  gem 'spring-watcher-listen', '~> 2.0.0'
end

gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

我已经关注了视频和其他博客帖子，我得到了以下错误：

Started GET "/collections.json" for 14.144.15.10 at 2016-07-19 00:26:03 +0000
ActiveRecord::SchemaMigration Load (0.1ms)  SELECT "schema_migrations".* FROM "schema_migrations"

当我访问集合(http://mydevapp.com/collections.json)的索引页面时，我会得到：

{"errors":[{"title":"Not acceptable","detail":"All requests must use the 'application/vnd.api+json' Accept without media type parameters. This request specified 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8'.","code":"406","status":"406"}]}
