java.net.SocketTimeoutException 仅在某些 Android 设备上抛出

Question

我正在尝试从 Android 设备上传 JPEG 图像文件。我正在使用该square/okhttp库来创建请求。我在联想 Yoga 平板电脑上遇到了这个问题，当我尝试上传图像时，出现以下异常。但是，当我在 Samsung Galaxy Tab 10" 上运行相同的代码时，一切正常，图像上传成功。

相机捕获图像并将其存储在 /storage/emulated/0/ 中，应用程序将从此处获取图像并尝试上传。我有一个在后台运行的服务来执行上传。

final MediaType MEDIA_TYPE_IMAGE_JPEG = MediaType.parse("image/jpeg");

        File file = new File(path);
        Request request = new Request.Builder()
                .url(baseUrl)
                .addHeader("timestamp", map.get("timestamp"))
                .addHeader("Content-Type", map.get("Content-Type"))
                .post(RequestBody.create(MEDIA_TYPE_IMAGE_JPEG, file))
                .build();

        OkHttpClient client = new OkHttpClient();
        Response response = client.newCall(request).execute();

例外：

Answer 1

您必须增加服务器端的读/写超时。Android 的临时解决方法是增加 OkHttp3 客户端的默认超时时间：

OkHttpClient client = new OkHttpClient.Builder()
        .connectTimeout(60, TimeUnit.SECONDS)
        .writeTimeout(120, TimeUnit.SECONDS)
        .readTimeout(60, TimeUnit.SECONDS)
        .build();
