在 Socket.io-client 中發送自定義 header

Question

在socket.io-client中發送自定義 header 時遇到問題。 服務器端集成/代碼一切正常，因為 iOS 代碼工作正常。 這是我在 iOS 中的代碼：

let manager = SocketManager(socketURL: URL(string: "http://server_url_here/")!, 
                            config: [.log(true), 
                                     .compress, .extraHeaders(["Authorization": "Bearer \(Defaults[.authToken])"])])

現在我嘗試了socket.io-client文檔中提到的方法。這是我使用的代碼：

final OkHttpClient httpClient = new OkHttpClient.Builder()
                    .addNetworkInterceptor(new CustomHeaderInterceptor())
                    .build();

//options    
final IO.Options options = new IO.Options();

options.webSocketFactory = httpClient;
options.callFactory = httpClient;

//manager
Manager manager = new Manager(URI.create(Constants.BASEURL));
socket = manager.socket("/event/0", options);

socket.connect();

但這在套接字錯誤處理程序中給出了錯誤：

io.socket.engineio.client.engineioexception xhr post 錯誤

我也嘗試使用下面的代碼但不工作：

socket.io().on(Manager.EVENT_TRANSPORT, new Emitter.Listener() {
    @Override
    public void call(Object... args) {
        Transport transport = (Transport) args[0];
        // Adding headers when EVENT_REQUEST_HEADERS is called
        transport.on(Transport.EVENT_REQUEST_HEADERS, new Emitter.Listener() {
            @Override
            public void call(Object... args) {
                Map<String, List<String>> mHeaders = (Map<String, List<String>>)args[0];
                mHeaders.put("Authorization", Arrays.asList(auth_token_with_bearer));        
            }
        });
        transport.on(Transport.EVENT_RESPONSE_HEADERS, new Emitter.Listener() {
            @Override
            public void call(Object... args) {
                @SuppressWarnings("unchecked")
                Map<String, List<String>> headers = (Map<String, List<String>>)args[0];
                // access response headers
                String auth = headers.get("Authorization").get(0);


            }
        });
    }
});

我閱讀了許多與此問題相關的主題，但沒有一個對我有用。 請讓我知道我現在哪里錯了。

OkHttpClient.Builder httpClient = new OkHttpClient.Builder();

httpClient.addInterceptor(new Interceptor() {

@Override
public Response intercept(Interceptor.Chain chain) throws IOException {
    Request original = chain.request();

    Request request = original.newBuilder()
        .header("User-Agent", "Your-App-Name")
        .header("Accept", "application/json")
        .header("your_header_key", "value")
        .method(original.method(), original.body())
        .build();

    return chain.proceed(request);
}
}

 OkHttpClient client = httpClient.build();
