C# Aliyun OSS 批量删除文件
前言
最近项目测试阶段，在Aliyun OSS上存储了很多测试上传的文件，由于文件较多，即使使用Oss Brower，删起来也不方便，因此就想着写个工具，方便对OSS上的文件进行删除操作。
正文
1.新建工程，导入工具包
新建VS控制台工程，安装NuGet工具包，注意不要选错工具包，如果选择上面的Aliyun.OSS.SDK.NetCore，在调用ListBuckets等查询接口时，会报异常：“无法发送具有此谓词类型的内容正文”，具体请看我写的这篇文章C# Aliyun OSS 获取Bucket列表异常：无法发送具有此谓词类型的内容正文
2.使用建表符，使界面更加友好，任意时刻按Q/q可退出程序
using Aliyun.OSS;
using System;
using System.Collections.Generic;
//一些全局变量
private string m_DefaultEndpoint = "" ;
private string m_DefaultAccessKeyId = "" ;
private string m_DefaultAccessKeySecret = "" ;
private string m_Endpoint;
private string m_AccessKeyId;
private string m_AccessKeySecret;
IEnumerable<Bucket> buckets;
private string m_BucketName;
private string m_Order;
private OssClient m_OssClient;
public void Run()
{
Console.WriteLine("┌─────────────────────────────────┐");
Console.WriteLine("│ Ctrl+C 强制 Press Q/q at any time to exit │");
Console.WriteLine("│ │");
Console.WriteLine("│ Aliyun OSS Delete Program │");
Console.WriteLine("│ │");
Console.WriteLine($"│ EnpPoint: {m_DefaultEndpoint} │");
Console.WriteLine($"│ AccessKeyId: {m_DefaultAccessKeyId} │");
Console.WriteLine($"│ AccessKeySecret: {m_DefaultAccessKeySecret} │");
Console.WriteLine("└─────────────────────────────────┘");
Console.WriteLine("");
Login();
}
private string GetOrder()
{
string input = Console.ReadLine().Trim();
if (input.Equals("Q") || input.Equals("q"))
{
Console.WriteLine("");
Console.WriteLine("Press any key to close.");
Console.ReadKey();
Environment.Exit(0);
return null;
}
else
{
return input;
}
}
3.创建OssClient，并拉取Bucket列表
private void Login()
{
while (true)
{
Console.Write("Use the default AK ? (Y/N): ");
m_Order = GetOrder();
if (m_Order.Equals("Y") || m_Order.Equals("y"))
{
m_Endpoint = m_DefaultEndpoint;
m_AccessKeyId = m_DefaultAccessKeyId;
m_AccessKeySecret = m_DefaultAccessKeySecret;
break;
}
else if (m_Order.Equals("N") || m_Order.Equals("n"))
{
Console.Write("Please enter the Enppoint: ");
m_Order = GetOrder();
if (!string.IsNullOrEmpty(m_Order))
{
m_Endpoint = m_Order;
}
Console.Write("Please enter the AccessKeyId: ");
m_Order = GetOrder();
if (!string.IsNullOrEmpty(m_Order))
{
m_AccessKeyId = m_Order;
}
Console.Write("Please enter the AccessKeySecret: ");
m_Order = GetOrder();
if (!string.IsNullOrEmpty(m_Order))
{
m_AccessKeySecret = m_Order;
}
break;
}
else
{
CLog.LogLine(CLog.LogType.Error, "Input Error!");
}
}
m_OssClient = new OssClient(m_Endpoint, m_AccessKeyId, m_AccessKeySecret);
try
{
buckets = m_OssClient.ListBuckets();
BucketOperation();
}
catch (Exception ex)
{
CLog.Log(CLog.LogType.Error, "Login Failed: ");
CLog.LogLine(CLog.LogType.Error, ex.Message);
Console.Write("重新登陆？(Y/N): ");
m_Order = GetOrder();
if (m_Order.Equals("Y") || m_Order.Equals("y"))
{
Console.Clear();
Run();
}
}
}
4. 列举拉取到的Bucket列表
private void BucketOperation()
{
Console.WriteLine("");
Console.WriteLine("────────────── Buckets List ──────────────");
int index = 0;
foreach (var bucket in buckets)
{
CLog.Log(CLog.LogType.Log, string.Format("{0,-30}", bucket.Name));
index++;
if (index % 3 == 0)
{
CLog.Log(CLog.LogType.Log, "\r\n");
}
else
{
CLog.Log(CLog.LogType.Log, "\t");
}
}
Console.WriteLine("");
while (true)
{
Console.Write("Please enter the bucket's name to delete: ");
m_Order = GetOrder();
if (DoesBucketExist(buckets, m_Order))
{
m_BucketName = m_Order;
Console.WriteLine("");
break;
}
else
{
CLog.LogLine(CLog.LogType.Error, $"Not Found the bucket: {m_Order}");
}
}
ObjectsOperation();
}
private bool DoesBucketExist(IEnumerable<Bucket> bucketList, string bucketName)
{
foreach (var bucket in bucketList)
{
if (bucket.Name.Equals(bucketName))
{
return true;
}
}
return false;
}
5. 判断要删除Bucket中的全部Object，还是某个Object
private void ObjectsOperation()
{
while (true)
{
Console.Write("Delete All Objects ? (Y/N): ");
m_Order = GetOrder();
if (m_Order == "Y" || m_Order == "y")
{
DeleteAllOjbects();
break;
}
else if (m_Order == "N" || m_Order == "n")
{
DeleteObject();
break;
}
else
{
CLog.LogLine(CLog.LogType.Error, "Input Error!");
}
}
}
6. 删除Bucket中的全部Object
private void DeleteAllOjbects()
{
Console.WriteLine("");
Console.WriteLine("───────────── Delete Objects ──────────────");
try
{
int delMaxKeys = 10;
int delCount = 0;
List<string> keys = new List<string>(delMaxKeys);
while (true)
{
var listObjectsRequest = new ListObjectsRequest(m_BucketName)
{
// 默认100，最大返回1000条记录。
MaxKeys = delMaxKeys,
};
var objectsList = m_OssClient.ListObjects(listObjectsRequest);
keys.Clear();
foreach (var summary in objectsList.ObjectSummaries)
{
keys.Add(summary.Key);
}
if (keys.Count == 0)
{
ClearConsoleLine(0);
Console.WriteLine($"{delCount++} items have been deleted.");
Console.WriteLine("All objects have been deleted.");
break;
}
DeleteObjectsRequest request = new DeleteObjectsRequest(m_BucketName, keys, false);
DeleteObjectsResult result = m_OssClient.DeleteObjects(request);
DeleteObjectsResult.DeletedObject[] deletedKeys = result.Keys;
int count = deletedKeys.Length;
for (int i = 0; i < count; i++)
{
ClearConsoleLine(0);
Console.Write($"{delCount++} items have been deleted. Deleting: {deletedKeys[i]}");
}
}
}
catch (Exception ex)
{
CLog.LogLine(CLog.LogType.Error, $"[ERROR]: {ex.Message}");
}
}
private void ClearConsoleLine(int lineBefore)
{
int currentLineCursor = Console.CursorTop;
Console.SetCursorPosition(0, Console.CursorTop - lineBefore);
Console.Write(new string(' ', Console.WindowWidth));
Console.SetCursorPosition(0, currentLineCursor - lineBefore);
}
7. 删除Bucket中的某个Object
private void DeleteObject()
{
Console.WriteLine("");
Console.WriteLine("───────────── Delete Object ──────────────");
string objectName = "";
while (true)
{
Console.Write("Please enter the object's name to delete: ");
m_Order = GetOrder();
if (m_OssClient.DoesObjectExist(m_BucketName, m_Order))
{
objectName = m_Order;
break;
}
else
{
CLog.LogLine(CLog.LogType.Error, "The object is not exist!");
}
m_OssClient.DeleteObject(m_BucketName, objectName);
Console.WriteLine($"Deleted: {m_BucketName}/{objectName}");
}
}
