我正在使用 PlayFramework 2.1.4 和 SecureSocial 2.1.1。

我定义routes如下,将请求设置为POST.

POST    /postComment                                  controllers.Application.postComment

一开始很顺利,但在 SecuredAction 之后,请求变为GET. 日志:

[info] application - onRouteRequest() requestHander = POST /postComment
[debug] application - [securesocial] anonymous user trying to access : '/postComment'
[debug] application - [securesocial] assets controller = controllers.ReverseAssets
[info] application - onRouteRequest() requestHander = GET /login
[error] application - [securesocial] can't find provider for id userpass
[info] application - onRouteRequest() requestHander = GET /authenticate/facebook
[debug] application - [securesocial] user logged in : [SocialUser(IdentityId( ...)]
[info] application - onRouteRequest() requestHander = GET /postComment
[warn] application - onHandlerNotFound() requestHander = GET /postComment

我该怎么办?请给我你的建议。

表单是这样的(createComment.scala.html)。

@helper.form(action=routes.Application.postComment){
@helper.textarea(commentForm("body"))
<div class="actions">
        <input type="submit" class="btn primary" value="submit">
</div>
}

这是 Application.scala

case class CommentData(body: String, vote: String)

object Application extends Controller with SecureSocial {
val commentForm = Form(mapping("body" -> nonEmptyText)(CommentData.apply)(CommentData.unapply))
def postComment = SecuredAction { implicit request =>
val id=session.get("targetCommentId");
commentForm.bindFromRequest.fold(
formWithErrors => {
BadRequest(views.html.createComment(commentForm)).withSession(session+"targetCommentId"->id.toString)
},
commentData => {
val id = request.user.identityId.userId
val body = commentData.body
application.Application.createComment(id, body)
Ok(views.html.topiclist())
})
}
}

SecureSocial 在身份验证后重定向到原始页面,但会使用 303 See Other 响应来执行此操作,这将导致对目标资源的 GET 请求。虽然说您不能重定向到 POST 请求是一种简化,但它不适用于 SecureSocial AFAIK。

处理此问题的更好方法是在用户提交评论表单之前提示进行身份验证,即:

  • 匿名用户想要创建评论并单击“添加评论”(或其他)
  • 通过FB做认证
  • 重定向回评论表单 (GET),现在使用经过身份验证的用户
  • 继续处理表单提交 (POST)

您可以在此处阅读有关 POST 重定向的一些问题。
