问题描述
以下是我使用 retrofit2 执行的多部分请求。
我想要的是以某种方式获得 upload percentage 的回调。 但我找不到合适的方法来做到这一点。我见过的方法很少，但它们只使用 single 文件。 我想要实现的是获取合并请求中发送的所有文件的上传进度百分比。
@Multipart
@POST("post/vehicle/detail")
Call<SuccessModel> uploadVehicle(
@Part("user_id") int userId,@Part("name") String vehicleName,@Part("number") int stockNumber,@Part MultipartBody.Part mainImage,@Part MultipartBody.Part hoodsImage,@Part MultipartBody.Part bumperImage,@Part MultipartBody.Part interiorImage,@Part MultipartBody.Part frontSeatimage,@Part MultipartBody.Part backSeatimage,@Part MultipartBody.Part dashboardImage,@Part MultipartBody.Part headLampsImage,@Part MultipartBody.Part tailLightsImage,@Part MultipartBody.Part backEngineImage
);
