persistableUpload = upload.getResumeableMultipartUploadId();
获取的值一直是null。

服务只是起到传递数据流, 不适合直接下载文件到本地, 有没有相应的方法
// 初始化 TransferConfig
TransferConfig transferConfig = new TransferConfig();
// 初始化 TransferManager
TransferManager transferManager = new TransferManager(cosXml, transferConfig);
String bucket = "examplebucket-1250000000"; //存储桶,格式:BucketName-APPID
String cosPath = "exampleobject"; //对象在存储桶中的位置标识符,即称对象键
String srcPath = @"temp-source-file";//本地文件绝对路径
if (!File.Exists(srcPath)) {
// 如果不存在目标文件,创建一个临时的测试文件
File.WriteAllBytes(srcPath, new byte[1024]);
}
// 上传对象
COSXMLUploadTask uploadTask = new COSXMLUploadTask(bucket, "COS_REGION", cosPath); // COS_REGION 为存储桶所在地域
uploadTask.SetSrcPath(srcPath);
// 同步调用
var autoEvent = new AutoResetEvent(false);
uploadTask.progressCallback = delegate (long completed, long total)
{
Console.WriteLine(String.Format("progress = {0:##.##}%", completed * 100.0 / total));
};
uploadTask.successCallback = delegate (CosResult cosResult)
{
COSXML.Transfer.COSXMLUploadTask.UploadTaskResult result = cosResult
as COSXML.Transfer.COSXMLUploadTask.UploadTaskResult;
Console.WriteLine(result.GetResultInfo());
string eTag = result.eTag;
autoEvent.Set();
};
uploadTask.failCallback = delegate (CosClientException clientEx, CosServerException serverEx)
{
if (clientEx != null)
{
Console.WriteLine("CosClientException: " + clientEx);
}
if (serverEx != null)
{
Console.WriteLine("CosServerException: " + serverEx.GetInfo());
}
autoEvent.Set();
};
transferManager.Upload(uploadTask);
// 等待任务结束
autoEvent.WaitOne();
确定2200年了,还使用这种逻辑?
// 初始化 TransferConfig
TransferConfig transferConfig = new TransferConfig();
// 初始化 TransferManager
TransferManager transferManager = new TransferManager(cosXml, transferConfig);
String bucket = "examplebucket-1250000000"; //存储桶,格式:BucketName-APPID
String cosPath = "exampleobject"; //对象在存储桶中的位置标识符,即称对象键
string localDir = System.IO.Path.GetTempPath();//本地文件夹
string localFileName = "my-local-temp-file"; //指定本地保存的文件名
// 下载对象
COSXMLDownloadTask downloadTask = new COSXMLDownloadTask(bucket, cosPath,
localDir, localFileName);
downloadTask.progressCallback = delegate (long completed, long total)
{
Console.WriteLine(String.Format("progress = {0:##.##}%", completed * 100.0 / total));
};
try {
COSXML.Transfer.COSXMLDownloadTask.DownloadTaskResult result = await
transferManager.DownloadAsync(downloadTask);
Console.WriteLine(result.GetResultInfo());
string eTag = result.eTag;
} catch (Exception e) {
Console.WriteLine("CosException: " + e);
}
代码运行完成后,下载的资源文件会被进程占用,排查回调死锁导致FileStream未关闭
已经上传的文件支持重新编辑文件自定义请求头吗?
