iOS 上的 Apollo 客户端和 Hasura 身份验证

Question

我正在尝试在 iOS 上使用 apollo 客户端实现订阅，我查看了 this 线程，但它对我不起作用。我仍然收到这个Authentication hook unauthorized this request, code: 1000 或Operation couldn't be completed Starscream.WSError error 1

我的代码是：

let apollo: ApolloClient = {
    let authPayload = ["X-Hasura-Access-Key": "<my_key>",
                       "Content-Type": "application/json"]

    let configuration = URLSessionConfiguration.default
    configuration.httpAdditionalHeaders = authPayload

    let map: GraphQLMap = authPayload

    let url = URL(string: "https://url")!
    let wsUrl = URL(string: "wss://url")!

    let httpNetworkTransport = HTTPNetworkTransport(url: url, configuration: configuration)
    let wsNetworkTransport = WebSocketTransport(request: URLRequest(url: wsUrl), connectingPayload: map)

    return ApolloClient(networkTransport: SplitNetworkTransport(httpNetworkTransport: httpNetworkTransport,
                                                            webSocketNetworkTransport: wsNetworkTransport))
}()

它在查询方面工作得很好，但在 websocket 和订阅方面却不行。我做错了什么？

UPD：这很有趣，但如果我删除 wsNetworkTransport 中的有效负载，错误仍然存​​在。另外，如果我通过request.addValue手动添加请求头，错误又是一样的。

我这样称呼客户：

apollo.subscribe(subscription: OrdersSubscription(id: "123")) { (result, error) in
        error == nil ? print(result!) : print(error!)
}

我还缺少任何其他设置吗？这东西真的缺少文档。

这段代码 sn-p 应该可以工作：

let authPayloads = [
  "X-Hasura-Access-Key": "<key>"
]
let map: GraphQLMap = ["headers": authPayloads]
let websocket = WebSocketTransport(request: urlRequest, connectingPayload: map)

有效载荷映射的结构需要稍有不同。
