public class ApiUploadV2UploadPart
extends ApiUpload

分片上传 v2 版 api: 分块上传数据 初始化一个 Multipart Upload 任务之后，可以根据指定的 EncodedObjectName 和 UploadId 来分 Part 上传数据。

一个文件被分成多个 part，上传所有的 part，然后在七牛云根据 part 信息合成文件 |----------------------------- file -----------------------------| |------ part ------|------ part ------|------ part ------|... |----- etag01 -----|----- etag02 -----|----- etag03 -----|... allBlockCtx = [{"partNumber":1, "etag", etag01}, {"partNumber":2, "etag", etag02}, {"partNumber":3, "etag", etag03}, ...]

上传过程： 1. 调用 ApiUploadV2InitUpload api 创建一个 upload 任务，获取 uploadId ApiUploadV2InitUpload.Response.getUploadId() 2. 重复调用 ApiUploadV2UploadPart api 直到文件所有的 part 均上传完毕, part 的大小可以不相同 3. 调用 ApiUploadV2CompleteUpload api 组装 api 选用接口： 1. ApiUploadV2ListParts 列举已上传的 part 信息 2. ApiUploadV2AbortUpload 终止上传

注意事项： 1. partNumber 范围是 1 ~ 10000 2. 除最后一个 Part 外，单个 Part 大小范围 1 MB ~ 1 GB 3. 如果你用同一个 PartNumber 上传了新的数据，那么服务端已有的这个号码的 Part 数据将被覆盖 4. ApiUploadV2InitUpload、ApiUploadV2UploadPart、ApiUploadV2CompleteUpload、ApiUploadV2ListParts、 ApiUploadV2AbortUpload 分片 V2 API的 key 需要统一（要么有设置且相同，要么均不设置）
