scala - WS Play Framework（scala）中的“您必须登录”错误

问题描述

我收到如下错误：

{"error":"You must be logged in to complete this action"} 
{"error":"You must be logged in to complete this action"}

即使，据推测，我已经通过身份验证，如下面的代码所示。我的代码看起来：

val baseURL = “https://www.dummywebsitename.org”
val authenticationPath = “/ajaxauth/login”
val queryPath = “/basicdomaindata/query/class/tle/ABC/CDE”
val loginURL = baseURL+authenticationPath
val queryURL = baseURL+queryPath

下面，我创建了一个 cookie，然后通过身份验证执行请求，最后尝试从远程 RESTful 服务获取数据。

val cookie = DefaultWSCookie("cookieName", "cookieValue", None, None, Some((2*60*60).toLong), true, true)

val wsRequest = ws.url(loginURL).withAuth(userName, password, WSAuthScheme.BASIC).addCookies(cookie).get()

val wsDataRequest = ws.url(queryURL).post(file)

当我运行代码时，出现上述错误。

解决方案

不确定，但您可能应该使用WSResponse.cookies方法直接从 wsRequest 使用 cookie。

//Not tested. Don't have prepared env :(
val reqLogin = ws.url(loginURL)
  .withAuth(userName, password, WSAuthScheme.BASIC)
  .addCookies(cookie)
  .get()

val wsDataRequest = reqLogin
.filter(_.status == 200)
.flatMap { loginRes => 
//even if we are in Success() branch of Future here, it doesn't mean
//request was made well. It means only we have touched server successfully.
//We still need to check if login was success and so on.
// to see what login result relly is println or check below values:
//loginRes.statusText 
//loginRes.status 
//loginRes.body

  ws.url(queryURL)
    .withCookies(loginRes.cookies :_*)
    .post(file)
}
