用于移动应用程序用户登录的Ruby on Rails Web服务

Question

我正在构建web＆amp;我正在使用ROR构建Web应用程序的移动应用程序。我正在使用Rails 4和Devise 3作为身份验证模块，并在我的应用程序中实现它。但现在我想从移动应用程序构建用于用户身份验证的Web服务。我已经按照这些教程First one和Second one进行了操作，但是当我测试这些服务时，它说500：内部服务器错误，这里是pic。

除此之外，我认为token_authenticable已经降级了......所以请让我知道我哪里出错了，或者提供一些很好的教程来使用设计认证在ROR中创建Web服务。感谢

Answer 1

我找到了解决方案，我错过了一些非常愚蠢的东西，或者我很想在轨道上使用红宝石。

每当您遇到500内部错误时，请检查以下内容

1. 检查rails服务器端的日志，非常有用
2. 此问题主要是由于rails端代码中的语法问题
3. 可能是您传递的参数或实际字段退出模型的问题
4. 检查模型中的验证，可能会阻止您的请求

我认为问题主要在于这些问题，但可能是我缺少一些。
