Changing URL for devise_token_auth sign_in

Question

我使用devise_token_auth并尝试更改用户sign_in url。我的 api/v2/文件夹中有sessions_controller， devise_token_auth 路由如下：

路由：

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

当我做rake routes时，我会得到我想要的路由：

api_v2_users_sign_in POST /api/v2/users/sign-in(.:format) api/v2/sessions#create

但是，当我尝试击中URL时，我会收到以下错误：

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URL为api/v2/users/sign-in。请帮助我。

谢谢..

Answer 1

我通过将路由中的默认范围添加到下面的用户来解决：

：

      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是命名的，那么使用名称置devise_scope ..
