在我的Rails(5.1)应用程序中,我使用devise进行身份验证并使用ActionCable。
我的ActionCable连接如下所示:
现在我想使用
但是遇到了错误:
我的ActionCable连接如下所示:
module ApplicationCable
class Connection < ActionCable::Connection::Base
identified_by :current_user
def connect
puts 'current_user:', current_user.inspect
self.current_user = find_verified_user
logger.add_tags 'ActionCable', current_user.id
end
def disconnect
# ...
end
protected
def find_verified_user
verified_user = env['warden'].user
return verified_user if verified_user
reject_unauthorized_connection
end
end
end
现在我想使用
action-cable-testing
gem进行测试:require 'rails_helper'
RSpec.describe ApplicationCable::Connection, type: :channel do
let(:user) { create(:user) }
before do
stub_connection(current_user: user)
end
it 'successfully connects' do
expect { connect '/cable' }.to_not raise_error
end
end
但是遇到了错误:
ApplicationCable::Connection
current_user:
nil
successfully connects (FAILED - 1)
Failures:
1) ApplicationCable::Connection successfully connects
Failure/Error: expect { connect '/cable' }.to_not raise_error
expected no Exception, got #<NoMethodError: undefined method `[]' for nil:NilClass> with backtrace:
# ./app/channels/application_cable/connection.rb:19:in `find_verified_user'

我有两个问题:
为什么current_user
的值是nil
?- 我该如何验证用户身份?
stub_connection
很有意义,但对于连接来说则没有用处。 - neversleep
