Java中的SecureSocial中的自定义视图

Question

我看到了一些关于这个话题的问题,但没有人回答我被困在的部分.顺便说一句,基于人们遇到的问题,我可能会建议给出一个模板插件的默认java实现.

我遇到的问题是,我将两个所需的视图从SecureSocial复制到我的views文件夹,并改变了RequestHeader,正如其他人注意到的那样:play.api.mvc.RequestHeader,现在我得到:

ambiguous implicit values: both method requestHeader in object PlayMagicForJava of type => play.api.mvc.RequestHeader and value request of type play.api.mvc.RequestHeader match expected type play.api.mvc.RequestHeader

版本:Play-2.1.1,Java 7,Master的SecureSocial.

请求必须明确地传递给登录模板,登录模板必须明确地将请求传递给提供者模板,并且提供者模板必须在调用RoutesHelper.authenticateByPost("userpass").absoluteURL时指定请求.更详细:

1. java TemplatesPlugin应该有这个getLoginPage实现:

   @Override
   public <A> Html getLoginPage(final play.api.mvc.Request<A> request, final Form<Tuple2<String, String>> form,
           final Option<String> msg) {
       return views.html.login.render(request, form, msg);
   }
   

2. 参数(第一行)login.scala.html应如下所示:

   @(request: play.api.mvc.RequestHeader, loginForm: play.api.data.Form[(String,String)], errorMsg: Option[String] = None)
   

3. 将调用更改login.scala.html为provider模板以明确传递请求(我们将在下一步调整其参数).

   1. login.scala.html 第41行,改变

      @provider(p.id)
      

      至

      @provider(request, p.id)
      

   2. login.scala.html 第55行,改变

      @provider("userpass", Some(loginForm))
      

      至

      @provider(request, "userpass", Some(loginForm))
      

4. 参数(第一行)provider.scala.html应该将请求作为第一个显式参数:

   @(request: play.api.mvc.RequestHeader, providerId: String, loginForm: Option[play.api.data.Form[(String, String)]] = None)
   

5. 提供者模板的第20行需要传递请求(以便调用正确的方法,否则你会得到一个RuntimeException: There is no HTTP Context available from here):

   <form action = "@securesocial.core.providers.utils.RoutesHelper.authenticateByPost("userpass").absoluteURL(IdentityProvider.sslEnabled)(request)"
   

这应该是所有需要的更改,如果您使用其他模板,则必须相应地进行调整.

只是提到它:我已经将我们的java TemplatesPlugin更改为scala版本(让它更直接).
