我不知道为什么,直到今天这个问题还没有解决,我暂时没有更改此控制器中的任何代码,但我似乎突然无法跨请求保存信息在我用Play 2.6制作的应用程序中。在我的LoginController中,当用户在表单中填写凭证时,我从POST请求调用此方法:
def attemptLogin() = Action {
implicit request: Request[AnyContent] => {
loginform.bindFromRequest().fold(
formWithErrors => BadRequest(views.html.login(formWithErrors)),
successfulForm => {
val validator: DbInputValidator = ... // validation object, stores Form info
if (validator.inputsAreValid) {
val userName = ... // retrieves user name from Form info
Ok(views.html.loginSuccess())
.withSession(request.session + ("authenticated" -> "true") + ("username" -> userName))
.withHeaders(SecurityHeadersFilter
.CONTENT_SECURITY_POLICY_HEADER -> " .fontawesome.com .fonts.googleapis.com maps.googleapis.com")
} else {
BadRequest(views.html.login(loginform))
}
}
)
}
}
我加载的view.html.successLoginResponse
如下:
@()(implicit request: RequestHeader)
@getAuthAndUserName = @{
val foundUsername: String = request.session.get("username").getOrElse("no username found")
val foundAuthenticated: String = request.session.get("authenticated").getOrElse("No authentication found")
s"$foundUsername and $foundAuthenticated"
}
@main("Successful Login") {
@landingnavbar("login")
<div class="container">
<h1>Login Successful</h1>
<h2>The auth token and username are:</h2>
<h2 id="headerValues">@getAuthAndUserName</h2>
<h2>Redirecting you to the Dashboard in...</h2>
<h3>
<div id="counter">3</div>
</h3>
</div>
<!-- JS here which automatically redirects to a URL after countdown -->
<script>...</script>
}
但是当加载时,我在视图中检测到的值是&#34;否则&#34;结果&#34;未找到用户名&#34;和&#34;未找到身份验证&#34;
很明显,返回的OK请求不存储信息,即使我确实将它们添加到了
.withSession(request.session + ("authenticated" -> "true") + ("username" -> userName))
行。在今天之前,它会这样做并且不会将信息显示给我,而是在任何后续页面加载时显示该请求
将检索数据,我将能够获取用户名或身份验证检查。它是否在顶部抓取隐式请求并将其加载到视图中?从首次调用attemptLogin()
的请求的旧版本?如果是这样,我如何让它取代新的会话数据?
我试过
request.session + ("authenticated" -> "true")
request.session + ("username" -> userName)
在Ok(...)
回复之前,但没有采取行动。
