Question

我想解析错误。在向后端发送请求后，我得到了回复：

这是我的错误解析器：

 public void parseNetworkError(Throwable t) {

        if (t instanceof UnknownHostException) {
            getView().showError(R.string.error_message_no_wifi);
            return;
        }

        if (t instanceof SocketTimeoutException || t instanceof SocketException) {
            getView().showError(R.string.error_message_timeout);
            return;
        }

        if (t instanceof IOException) {
            getView().showError(R.string.error_message_connection_error);
            return;
        }

        if (t instanceof HttpException) {
            HttpException httpException = (HttpException) t;
            try {
                String jsonError = httpException.response().errorBody().source().readUtf8();
                Gson gson = new GsonBuilder()
                        .registerTypeAdapter(ApiException.class, new ApiExceptionTypeAdapter())
                        .create();
                ApiException apiException = gson.fromJson(jsonError, ApiException.class);

                if (apiException == null) {
                    apiException = new ApiException();
                }

                if (apiException.getErrorMessage() == 0) {
                    if (httpException.code() == 500) {
                        getView().showError(R.string.error_message_server_error);
                        return;
                    } else {
                        getView().showError(R.string.error_message_unexpected_api_error);
                        return;
                    }
                }
                getView().showError(apiException.getErrorMessage());
            } catch (IOException | JsonSyntaxException e) {
                e.printStackTrace();
                getView().showError(R.string.error_message_unexpected_api_error);
            } catch(Exception ex){
                ex.printStackTrace();
                getView().showError(R.string.error_message_unknown);
            }
        } else {
            getView().showError(R.string.error_message_unknown);
        }
    }

但是在Throwable中我看不到X-Error消息。我怎么能得到这个？我使用OkHttp并进行改造。

Answer 1

OkHttp Response有一个headers()方法，允许您访问响应标头。您的httpException已response()返回Response，因此您应该可以在那里找到X-Error标题。

来自后端的X-Error
