在 rspec 中设计重定向而不是 json 响应
[英]devise redirects instead of json response in rspec
问题描述
I had overridden default responding in devise which renders json instead of html template.
我在设计中覆盖了默认响应，它呈现 json 而不是 html 模板。 It works fine when I test it with curl or postman, but when it comes to test it with rspec.当我用 curl 或 postman 测试它时它工作正常，但是当我用 rspec 测试它时。 I have read infos how to test controllers with devise from readme.md, so that it works fine with logging into, but does not work when I want to test unauthenticated request.我已经阅读了有关如何使用 readme.md 中的设计测试控制器的信息，以便它可以正常登录，但在我想测试未经身份验证的请求时不起作用。
Response received:收到回复：
<html><body>You are being <a href=\"http://test.host/users/sign_in\">redirected</a>.</body></html>
instead of:代替：
{"error":"You need to sign in or sign up before continuing."}
app/controllers/playlists_controller.rb:应用程序/控制器/播放列表_controller.rb：
class PlaylistsController < ApplicationController
before_action :authenticate_user!
def index
render json: Playlist.all
end
end
app/controllers/sessions_controller.rb:应用程序/控制器/sessions_controller.rb：
class SessionsController < Devise::SessionsController
clear_respond_to
respond_to :json
end
spec/controllers/playlists_controller_spec.rb:规格/控制器/playlists_controller_spec.rb：
require 'rails_helper'
describe PlaylistsController do
context 'when user is not signed in' do
it 'returns authorization error message' do
get :index
expect(response.body).to eq 'some message here'
end
end
end

In Rails 5, the only way I could get the controller action to process as JSON was :在 Rails 5 中，我可以让控制器操作作为 JSON 处理的唯一方法是：
get :action, params: { format: :json, ... }
Hope this can help !希望这可以帮助！

您可以定义FailureApp或使用条件过滤器，两者都在类似问题的答案中提出： https : //stackoverflow.com/a/10042104/580346

The reason it doesn't work in your controller test and does work in curl is because you aren't hitting the :index with format of :json (which you've written logic to respond_to :json ).它在您的控制器测试中不起作用并且在 curl 中起作用的原因是因为您没有使用:json格式访问:index （您已将逻辑写入respond_to :json ）。
Change this改变这个
it 'returns authorization error message' do
get :index
...
end
to this对此
it 'returns authorization error message' do
get :index, format: :json
...
end
