玩：会话Cookie未设置。使用JavaScript的Cookie无法读取 [英] Play: Session Cookie not set. Cannot read Cookie using Javascript

问题描述

为了给授权令牌（应当被存储在数据库中）发送到我的服务器，我在我的.scala.html文件AJAX调用。

In order to send an authorization token (that should be stored in a database) to my server, I do an AJAX call in my .scala.html file.

$.ajax({
       url: "http://localhost:9000/storeauthcode",
       type: 'get',
       data: {code: authResult['code']},
       contentType: 'application/json',
       dataType: 'json',
       success: function(result) {
       // Handle or verify the server response.
           console.log("you're fully logged in now.")
           console.log(JSON.stringify(result, null, 2))
           console.log("document.cookie = "+document.cookie)
       },
       error: function (xhr, status, error) {
           console.log("error\n")
           console.log(xhr.responseText)
       }

   });
  }

在服务器端，我存储在auth code，并返回一个JSON响应

On the server side, I store the auth code and return a json response

  def storeAuthCode  = Action { request =>
  //store credentials in database
  //...
  //return some data
  Ok(Json.toJson(Map("a"->"b"))).withSession("code"-> "someAuthCode", "id"->"someId")
}

如果我尝试通过

console.log("document.cookie = "+document.cookie)

的document.cookie看来虽然服务器应该创建一个会话cookie（或至少是任何东西）是空的。的document.cookie应该返回一个;我的Cookie的值分隔的列表。

document.cookie seems to be empty although the server should have created a session Cookie (or at least anything). document.cookie should return a ";" separated list of my Cookie values.

我怎样才能成功地把我的饼干？

How can I set my Cookies successfully?

推荐答案

为什么你不能看，这是的 仅Http 标志设置播放的会话cookie。

The reason why you can't read this is HTTPOnly flag set for Play's session cookie.

您有几种选择，你可以改用：

You have several options which you can use instead:

1. 发送 code 和 ID 中的JSON对象（如一 - ＆GT;B）

2. 您也可以送他们作为 响应头 ，所以你可以在你的成功回调中得到他们这样的：

1. Send code and id in the JSON object (like "a"->"b")

2. You can also send them as response headers so you can get them within your success callback like:

Ok(Json.toJson(Map("a" -> "b")))
  .withHeaders(
    "code" -> "foo",
    "id" -> "bar"
  )
  .withCookies(
    Cookie("code", "foo"),
    Cookie("id", "bar")
  )

jQuery的

jQuery

success: function(data, textStatus, jqXHR) {
    console.log(jqXHR.getResponseHeader('code'));
    console.log(jqXHR.getResponseHeader('id'));
},
