Apollo GraphQL标头在iOS Swift中总是显示失败

在我的swift项目中，我第一次与Apollo GraphQL客户合作。按照他们文档中提到的所有步骤，在谷歌上搜索我的问题，但没有运气。我通过在我的请求URL中传递一个头来发出一个查询请求，但它总是给我一个失败消息，比如失败（Apollo.LegacyParsingInterceptor.LegacyParsingError.couldNotParseToLegacyJSON（数据：1839字节））。我已经提到了的答案，但这对我来说并不适用。任何帮助都将不胜感激

static let shared = Network()

private(set) lazy var apollo: ApolloClient = {

    let cache = InMemoryNormalizedCache()
    let store1 = ApolloStore(cache: cache)
    let client1 = URLSessionClient()
    let provider = NetworkInterceptorProvider(store: store1, client: client1)
    
    let url = URL(string:"https://Storename.myshopify.com/admin/api/2021-04/graphql")!
    
    let requestChainTransport = RequestChainNetworkTransport(interceptorProvider: provider,endpointURL: url)
    
    return ApolloClient(networkTransport: requestChainTransport,
                        store: store1)
}()}


class RequestOrderDetailInterceptor: ApolloInterceptor {

func interceptAsync<Operation: GraphQLOperation>(
    chain: RequestChain,
    request: HTTPRequest<Operation>,
    response: HTTPResponse<Operation>?,
    completion: @escaping (Result<GraphQLResult<Operation.Data>, Error>) -> Void) {
    
    request.addHeader(name: "X-Shopify-Access-Token", value: "MyToken")
    print( "Outgoing request: \(request)")
    chain.proceedAsync(request: request,

我看到你最近对其他人问题的评论，只是想知道你是否取得了成功？我在这里找到了你的评论

请直接对这个问题发表评论。我尝试了@ChamathJeevan给出的相同代码语法，但它对我不起作用，我不知道为什么。

enum ResponseLoggingError: Error {
    case notYetReceived

    response: HTTPResponse<Operation>?,

                           completion: completion)

    }

    guard let receivedResponse = response else {

    if let stringData = String(bytes: receivedResponse.rawData, encoding: .utf8) {
        print("Data: \(stringData)")
    } else {
        print("Could not convert data to string!")
    }
}
