resumeProgressInfo method

void resumeProgressInfo(
  1. Map progress
)

恢复上传进度，注意这里还是需要自行调用 startUpload 方法

Implementation

void resumeProgressInfo(Map progress) {
  final localPath = progress['localPath'] as String;
  final remotePath = progress['remotePath'] as String;
  final memberLevel = progress['memberLevel'] as int;
  final saveFileLength = progress['saveFileLength'] as int;

  final lastModifiedMs = progress['lastModified'] as int;

  if (lastModifiedMs != lastModified.millisecondsSinceEpoch) {
    throw Exception('修改时间不一致，可能文件被修改过，不支持续传');
  }

  if (saveFileLength != fileTotalSize) {
    throw Exception('文件大小不一致，可能文件已经被修改，不支持续传');
  }

  // 读取上传的文件的 md5 码

  if (localPath != this.localPath || remotePath != this.remotePath) {
    throw Exception('localPath or remotePath is not equal');
  }

  if (memberLevel != this.memberLevel) {
    throw Exception('memberLevel 不一致，可能会造成分块大小不同，所以不支持续传');
  }

  _uploadId = progress['uploadId'];

  // 恢复生成的 md5 值
  _md5 = BaiduMd5.fromMap(progress['md5']);

  uploadCount = progress['uploadCount'] as int;
}
