django - 如何通过 Django Channels 将 cookie 添加到标头？

问题描述

在我的前端，我有以下配置。身份验证是手动的，因为 react native 在持久会话时失败：

...
const authLink = setContext(request =>
  storage.getCookie().then(cookie => ({
    // Before the request is sent: set cookie header
    headers: {
      cookie,
    },
    credentials: 'omit', // set cookies manually
  }))
)

const setTokenLink = new ApolloLink((operation, forward) => {
  // Send the request to the server
  return forward(operation).map(response => {
    // After response is returned: store cookie in local storage
    const context = operation.getContext()
    const {
      response: { headers },
    } = context

    if (headers) {
      storage.setCookie(headers.get('set-cookie'))
    }

    return response
  })
})
storage.getCookie().then(cookie => console.log(cookie))
// console.log('cookie', storage.getCookie().then(cookie => {cookie}))

const httpLink = createUploadLink({
  uri: `${domainApi}/graphql/`,
})

const wsClient = new SubscriptionClient(
  domainWs,
  {
    lazy: true,
    reconnect: true,
    connectionParams: {
      authToken: storage.getCookie(),
    },
  })
)
...

然而，这似乎会影响 websockets，因为在后端，标头不包含 cookie。

class GraphqlSubcriptionConsumer(SyncConsumer):
    def __init__(self, scope):
        super().__init__(scope)
        self.subscriptions = {}
        self.groups = {}

    def websocket_connect(self, message):
        self.send({"type": "websocket.accept", "subprotocol": "graphql-ws"})

    def websocket_disconnect(self, message):
        for group in self.groups.keys():
            group_discard = async_to_sync(self.channel_layer.group_discard)
            group_discard(f"django.{group}", self.channel_name)

        self.send({"type": "websocket.close", "code": 1000})
        raise StopConsumer()

    def websocket_receive(self, message):
        request = json.loads(message["text"])
        id = request.get("id")

        if request["type"] == "connection_init":
            return

        elif request["type"] == "start":
            print("scope user:", self.scope["user"]) //returns AnonymousUser
            print("scope headers:", self.scope["headers"]) //returns headers without the cookie
...

有了这个配置，我得到

{'type': 'websocket.receive', 'text': '{"type":"connection_init","payload":{"authToken":{"_40":0,"_65":1,"_55":"sessionid=bci028bzn1cgxyuynvb7fjevc5ynqdil","_72":null}}}'}

在每条带有 type 的第一条消息中connection_init。所以我想知道是否有一种方法可以手动将 django 中的 cookie（可能在内部if request["type"] == "connection_init":）插入范围，以便后续类型start的消息包含 cookie。

任何小提示/提示都有帮助。

要在服务器的握手响应中设置 cookie（用测试channels==2.3.1）：

def connect(self):  # connect method of your WebsocketConsumer
    # called on connection
    headers = {}
    headers['Set-Cookie'] = 'myCookie=myValue'
    self.accept(subprotocol=(None, headers))

一旦建立连接，就无法通过Set-CookieHTTP 响应标头将 cookie 从服务器发送到用户代理。那是因为它是一个开放的 TCP 套接字，协议不再是 HTTP。
