使用C#拉取云存储存储桶

using COSXML;
using COSXML.Auth;
using COSXML.Model.Object;
using COSXML.CosException;

// 创建 COS 客户端对象
CosXmlConfig config = new CosXmlConfig.Builder()
    .SetRegion("your-region")  // 设置存储桶所在的地域，例如：ap-guangzhou
    .SetDebugLog(true)  // 是否开启调试日志
    .Build();

QCloudCredentialProvider cosCredentialProvider = new DefaultQCloudCredentialProvider("your-secretId", "your-secretKey", 600);

CosXml cosXml = new CosXmlServer(config, cosCredentialProvider);

GetObjectRequest request = new GetObjectRequest("your-bucket", "your-object-key");

// 设置本地保存文件的路径
string localFilePath = "your-local-file-path";

GetObjectResult result = null;
try
{
    // 执行文件下载操作
    result = cosXml.GetObject(request, localFilePath);
}
catch (COSXML.CosException.CosServerException e)
{
    // 处理异常情况
    Console.WriteLine("CosServerException: " + e.GetInfo());
}
catch (COSXML.CosException.CosClientException e)
{
    // 处理异常情况
    Console.WriteLine("CosClientException: " + e.GetInfo());
}

if (result != null)
{
    // 下载成功，可以根据需要进行后续操作
    Console.WriteLine("Download success!");
