Hotwire rails 应用程序：重定向到外部服务失败答案

【问题标题】：Hotwire rails app: redirect to external service failsHotwire rails 应用程序：重定向到外部服务失败
【发布时间】：2021-05-16 19:01:57
【问题描述】：

我正在将 discourse 单点登录与 hotwire rails 应用程序集成，在重定向之前一切正常，当它重定向时，我看到有 CORS 问题浏览器，当然它的 turbo 请求因此它尝试从给定 URL 获取响应所以它抛出CORS 错误，我们如何在此处进行实际重定向？

  def sso
    secret = "572890bb92bbef8c4634c1bf"
    sso = SingleSignOn.parse(request.query_string, secret)
    sso.email = current_user.email # from devise
    sso.name = current_user.name # this is a custom method on the User class
    sso.username = current_user.username # from devise
    sso.external_id = current_user.id # from devise
    sso.sso_secret = secret

    redirect_to sso.to_url("https://xxxxxxxx/session/sso_login")
  end

【问题讨论】：

你能分享一下视图部分（链接、涡轮框架等）
@Joel_Blum 添加了视图，其设计生成的视图，正常的身份验证流程在应用程序中工作，仅在话语尝试使用我们的应用程序登录时发出。谢谢

标签： ruby-on-rails hotwire-rails turbo-frames

【解决方案1】：

我在登录表单中使用了data-turbo="false"，它会向后端发送 HTML 请求，因为当我进行重定向时，它会重定向整个页面。谢谢
