How to sign in a user using Devise from a Rails console?
提问by Christian
After loading the Rails console, how should I sign in a user?
加载 Rails 控制台后，我应该如何登录用户？
Devise provides a test helper which can be used in tests and I've tried to use in console:
Devise 提供了一个可以在测试中使用的测试助手，我已经尝试在控制台中使用：
>> include Devise::TestHelpers
>> helper.sign_in(User.first)
But I get:
但我得到：
NoMethodError: undefined method `env' for nil:NilClass
Anyway, I would like to use the real devise helper and not this test helper. Is there any way to achieve this?
无论如何，我想使用真正的设计助手而不是这个测试助手。有没有办法实现这一目标？

Here's one way I was able to do it:
这是我能够做到的一种方法：
>> ApplicationController.allow_forgery_protection = false
>> app.post('/sign_in', {"user"=>{"login"=>"login", "password"=>"password"}})
Then you can do:
然后你可以这样做：
>> app.get '/some_other_path_that_only_works_if_logged_in'
>> pp app.response.body

Here is another example which uses the csrf token, authenticates the user, and makes a POST/GET request.
这是另一个使用 csrf 令牌、验证用户并发出 POST/GET 请求的示例。
# get csrf token
app.get '/users/sign_in'
csrf_token = app.session[:_csrf_token]
# log in
app.post('/users/sign_in', {"authenticity_token"=>csrf_token, "user"=>{"email"=>"foo", "password"=>"bar"}})
# get new csrf token, as auth user
app.get ''
csrf_token = app.session[:_csrf_token]
# make a POST request
app.post '/some_request.json', {"some_value"=>"wee", "authenticity_token"=>csrf_token}
# make a GET request
app.get '/some_other_request.json'

You can add an action inside one of your controller, and use the technique explained here.
您可以在其中一个控制器中添加一个动作，并使用此处解释的技术。
class MyController < ApplicationController
# POST /my_controller/become {'email': '[email protected]'}
def become
raise 'not in development environment' unless Rails.env == 'development'
sign_in User.find_by_email(params[:email])
end
end

Important to note that since Rails 5, the params parsing has been changed to take only one argument and params (instead of params being a second argument.
重要的是要注意，从Rails 5 开始，params 解析已更改为仅采用一个参数和 params（而不是 params 作为第二个参数。
ActionDispatch::ParamsParser is deprecated and was removed from the middleware stack. To configure the parameter parsers use ActionDispatch::Request.parameter_parsers=
ActionDispatch::ParamsParser 已弃用并已从中间件堆栈中删除。要配置参数解析器，请使用 ActionDispatch::Request.parameter_parsers=
So these earlier examples will no longer work in modern Rails without patching your middleware. To make them work, simply include the arguments in the POST params like:
因此，如果不修补中间件，这些早期的示例将不再适用于现代 Rails。要使它们工作，只需在 POST 参数中包含参数，例如：
app.post('/users/sign_in', {"user"=>{"email"=>"[email protected]", "password"=>"mycoolpassword"}})<-- No longer valid
app.post('/users/sign_in', {"user"=>{"email"=>"[email protected]", "password"=>"mycoolpassword"}})<-- 不再有效
app.post('/users/sign_in', params: {"user"=>{"email"=>"[email protected]", "password"=>"mycoolpassword"}})<-- valid
app.post('/users/sign_in', params: {"user"=>{"email"=>"[email protected]", "password"=>"mycoolpassword"}})<--有效
