我使用devise_token_auth并尝试更改用户sign_in网址。我在api/v2/文件夹和 devise_token_auth 路由中有sessions_controller，如下所示：
路线：
namespace :api do
namespace :v2 do
mount_devise_token_auth_for 'User', at: 'users', :controllers => {
:registrations => 'api/v2/registrations',
:confirmations => 'api/v2/confirmations',
:passwords => 'api/v2/passwords',
:sessions => 'api/v2/sessions'}
post 'users/sign-in', to: 'sessions#create'
end
end
当我rake routes时，我会按照自己的意愿获得路线：
api_v2_users_sign_in POST /api/v2/users/sign-in(.:format) api/v2/sessions#create
但是，当我尝试点击网址时，我收到以下错误：
AbstractController::ActionNotFound (Could not find devise mapping for path "/api/v2/users/sign-in".
This may happen for two reasons:
1) You forgot to wrap your route inside the scope block. For example:
devise_scope :user do
get "/some/route" => "some_devise_controller"
end
2) You are testing a Devise controller bypassing the router.
If so, you can explicitly tell Devise which mapping to use:
@request.env["devise.mapping"] = Devise.mappings[:user]

我需要网址为api/v2/users/sign-in。请帮帮我。
谢谢..
答案 0 :(得分：1)
我通过在路线中向用户添加默认范围来解决这个问题，如下所示：
mount_devise_token_auth_for 'User', at: 'users', :controllers => {
:registrations => 'api/v2/registrations',
:confirmations => 'api/v2/confirmations',
:passwords => 'api/v2/passwords'
}, skip: [:sessions]
devise_scope :api_v2_user do
get 'users/sign-in', to: 'sessions#new'
post 'users/sign-in', to: 'sessions#create'
delete 'users/sign-out', to: 'sessions#destroy'
end
如果您的API是命名空间，那么使用命名空间devise_scope ..
