改造&okhttpclient拦截401响应

Question

我试图看到每当我从我的API获得代码401的响应.但是当我这样做时,我得到一个IOException

@Override
public Response intercept(Chain chain) throws IOException {
    Request request = chain.request();
    Response response = chain.proceed(request);
    if (response.code() == 401) {
        mLoginToken.delete();
        Toast.makeText(mApplication.getApplicationContext(), R.string.session_error, Toast.LENGTH_SHORT).show();
        Intent intent = new Intent(mApplication.getApplicationContext(), LoginActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
        mApplication.startActivity(intent);
    }
    return response;
}

我将得到错误java.io.IOException:连接上的意外结束流{proxy = DIRECT @ hostAddress = cipherSuite = none protocol = http/1.1}(recycle count = 0)

在线

        Response response = chain.proceed(request);

我应该如何获得401(未授权代码)的响应才能处理这个问题？

我通常只将请求程序用于请求,并且处理错误会在其余适配器构建器上设置错误处理程序,请参阅下面的示例:

注意:cause.getResponse()可能会返回null

   yourRestAdapterBuilder.setErrorHandler(new ErrorHandler() {
                        @Override
                        public Throwable handleError(RetrofitError cause) {
                            switch (cause.getResponse().getStatus()) {
                                case 401:
                                    mLoginToken.delete();
                                    Toast.makeText(mApplication.getApplicationContext(), R.string.session_error, Toast.LENGTH_SHORT).show();
                                    Intent intent = new Intent(mApplication.getApplicationContext(), LoginActivity.class);
                                    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
                                    mApplication.startActivity(intent);
                                default:
                                    // suppress or handle other errors
                                    break;
                            }
                        }
                    })
