OkHttp拦截器链在获取令牌时中断

Question

我有一个OkHttp拦截器，当请求得到401 HTTP错误时，它应该请求一个令牌。现在，登录服务的请求完成了，但随后链路中断，原始请求不再重试。下面是我的拦截器的拦截方法：

override fun intercept(chain: Interceptor.Chain): Response {
        logger.d("AuthenticationServiceHolder $authenticationServiceHolder")

        val originalRequest = chain.request()
        logger.d("Intercepting call to ${originalRequest.method()} ${originalRequest.url()}")

        val response: Response = chain.proceed(originalRequest)
        val successful = response.isSuccessful
        val code = response.code()
        logger.d("Response successful: $successful - code: $code")

        if (!successful && code == HttpURLConnection.HTTP_UNAUTHORIZED) {
            logger.d("Token is $token")

            val deviceUuid = deviceIdentificationManager.deviceUuid().blockingGet()
            logger.d("Device uuid $deviceUuid")
            if (deviceUuid != null) {
                val authenticationService = authenticationServiceHolder.get()
                if (authenticationService != null) {
                    token = reLogin(authenticationService, deviceUuid)
                    if (token != null) {
                        val headersBuilder = originalRequest.headers().newBuilder()
                        headersBuilder.removeAll(AUTHORIZATION_HEADER)
                        headersBuilder.add(AUTHORIZATION_HEADER, token!!)

                        val requestBuilder = originalRequest.newBuilder()
                        val request = requestBuilder.headers(headersBuilder.build()).build()
                        return chain.proceed(request)
                    } else {
                        logger.e("Token was not retrieved")
                    }
                } else {
                    logger.e("Authentication service is null!")
                }
            }
        }
        return response
}

reLogin（）方法是：

private fun reLogin(authenticationService: AuthenticationService, deviceUuid: UUID): String? {
        logger.d("reLogin() - authenticationService $authenticationService")
        val blockingGet = authenticationService?.login(LoginRequest(deviceUuid, clock.currentTime()))?.blockingGet()
        logger.d("reLogin() - response $blockingGet")
        val response = blockingGet ?: return null
        logger.d("reLogin() - token ${response.token}")
        return response.token
}

新：正如Mitesh Machhoya所说，我尝试了两个不同的改型实例，一个带有拦截器的okhttp客户端，另一个没有。现在登录调用没有被拦截，但是拦截器的执行被中断了，我的意思是这个类的日志跟踪是：

 - AuthenticationServiceHolder XXXmypackageXXX.AuthenticationServiceHolder... 
 - Intercepting call to GET XXXmyInterceptedCallXXX 
 - Response successful: false - code: 401 
 - Token is null 
 - Device uuid XXX 
 - reLogin() - authenticationService retrofit2.Retrofit$1@a5c0a25 

仅此而已。我的意思是relogin()-response.....不打印。我确信登录调用正在工作，因为我在okhttp日志中看到了登录响应。

用其他httpClient发出重新登录请求，而不附加拦截器，那么它就会像您预期的那样工作得很好。

如果您使用相同的httpClient发出重新登录请求，那么它将通过拦截器，并且每次都覆盖请求，所以尝试使用另一个httpClient发出请求
