示例
@code
QCloudUploadPartRequest* request = [QCloudUploadPartRequest new];
request.bucket = @"examplebucket-1250000000";
request.object = @"exampleobject";
request.partNumber = 1;
//标识本次分块上传的 ID;使用 Initiate Multipart Upload 接口初始化分块上传时会得到一个 uploadId
//该 ID 不但唯一标识这一分块数据,也标识了这分块数据在整个文件内的相对位置
request.uploadId = @"exampleUploadId";
//上传的数据:支持 NSData*,NSURL(本地 URL) 和 QCloudFileOffsetBody * 三种类型
request.body = [@"testFileContent" dataUsingEncoding:NSUTF8StringEncoding];
[request setSendProcessBlock:^(int64_t bytesSent,
int64_t totalBytesSent,
int64_t totalBytesExpectedToSend) {
//上传进度信息
}];
[request setFinishBlock:^(QCloudUploadPartResult* outputObject, NSError *error) {
QCloudMultipartInfo *part = [QCloudMultipartInfo new];
//获取所上传分块的 etag
part.eTag = outputObject.eTag;
part.partNumber = @"1";
// 保存起来用于最好完成上传时使用
self.parts = @[part];
}];
