我正在尝试从Android设备上载JPEG图像文件。我正在使用square/okhttp库创建请求。我在Lenovo Yoga平板电脑上遇到此问题，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，并且图像成功上传。
相机会捕获图像并将其存储在/ storage / emulated / 0 /中，应用将从此处将其拾取并尝试上传。我有一个在后台运行的服务执行上传操作。
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：

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