Ruby on rails 使用Desive进行RESTful登录(Rails 4)
如何在RubyonRails中使用Desive进行RESTful注册和登录(我使用的是版本4) 我找不到关于我应该发布到服务器的参数(例如电子邮件、密码)的任何文档 在当前版本的devise中,似乎不支持使用JSON数据(例如通过AJAX)的RESTful登录—默认行为是为任何类型的请求发回整个HTML页面,而不是专门处理JSON请求的JSON对象Ruby on rails 使用Desive进行RESTful登录(Rails 4),ruby-on-rails,json,rest,devise,gem,Ruby On Rails,Json,Rest,Devise,Gem,如何在RubyonRails中使用Desive进行RESTful注册和登录(我使用的是版本4) 我找不到关于我应该发布到服务器的参数(例如电子邮件、密码)的任何文档 在当前版本的devise中,似乎不支持使用JSON数据(例如通过AJAX)的RESTful登录—默认行为是为任何类型的请求发回整个HTML页面,而不是专门处理JSON请求的JSON对象 这是否意味着我需要创建/扩展自定义控制器,以便使用JSON处理RESTful应用程序的用户注册和登录?如果是,请详细说明。如果您使用的是Desive
这是否意味着我需要创建/扩展自定义控制器,以便使用JSON处理RESTful应用程序的用户注册和登录?如果是,请详细说明。如果您使用的是Desive,所有RESTful操作都是通过其窗体和控制器提供的(如果您浏览
http://your-app.com/users/sign_up
,您可以注册等)
如果您希望让Desive处理JSON,您是正确的,因为它不是“开箱即用”处理的,但幸运的是,有一种方法可以做到这一点:
