对象存储快速入门（.NET(C#) SDK）

一、相关资源

·SDK 源码下载请参见：XML .NET SDK。

·SDK 快速下载地址：XML .NET SDK。

·SDK 文档中的所有示例代码请参见 SDK 代码示例。

·SDK 更新日志请参见 ChangeLog。

·SDK 常见问题请参见：.NET（C#）SDK 常见问题。

注意：说明：

注意：如果你在使用 SDK 时遇到函数或方法不存在等错误，请先将 SDK 升级到最新版再重试。

二、环境配置与准备

·.NET SDK 基于 .NET Standard 2.0开发。

·Windows：安装 .NET Core 2.0及以上版本，或者 .NET Framework 4.5及以上版本。

·Linux/Mac：安装 .NET Core 2.0及以上版本。

·你需要获取一个腾讯云 API 密钥，该密钥是你使用 COS SDK 各项功能的前提。

注意：说明：

注意：关于文章中出现的 SecretId、SecretKey、Bucket 等名称的含义和获取方式请参见 COS 术语信息。

三、安装 SDK

我们提供 NuGet 的集成方式，你可以在工程的 csproj 文件里添加：

如果你是使用 .NET CLI，请使用如下命令安装：

dotnet add package Tencent.QCloud.Cos.Sdk

如果你是用于目标框架 .NET Framework 4.0 及以下版本的开发，请下载 Releases 并使用 COSXML-Compatible.dll 文件。

在 Visual Studio 项目中选择项目 > 添加引用 > 浏览 > COSXML-Compatible.dll 的方式添加 .NET(C#) SDK。

注意：说明：

注意：兼容包中不包含高级上传、下载等功能的支持，详情参见向下兼容指南。

四、初始化 COS 服务

下面为你介绍如何使用 COS .NET SDK 完成一个基础操作，例如初始化客户端、创建存储桶、查询存储桶列表、上传对象、查询对象列表、下载对象和删除对象。

SDK 中常用的命名空间有：

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

在执行任何和 COS 服务相关请求之前，都需要先实例化 CosXmlConfig , QCloudCredentialProvider , CosXmlServer3个对象。其中：

·CosXmlConfig 提供配置 SDK 接口。

·QCloudCredentialProvider 提供设置密钥信息接口。

·CosXmlServer 提供各种 COS API 服务接口。

五、初始化

注意：说明：

注意：下述初始化示例中使用的临时密钥，其生成和使用可参见临时密钥生成及使用指引。

//初始化 CosXmlConfig string region = "COS_REGION"; //设置一个默认的存储桶地域CosXmlConfig config = new CosXmlConfig.Builder() .IsHttps(true) //设置默认 HTTPS 请求 .SetRegion(region) //设置一个默认的存储桶地域 .SetDebugLog(true) //显示日志 .Build(); //创建 CosXmlConfig 对象

六、设置 API 访问密钥

SDK 中提供了3种方式：持续更新的临时密钥、不变的临时密钥、永久密钥。

持续更新的临时密钥（推荐）不变的临时密钥（不推荐）永久密钥（不推荐）因为临时密钥在一定时效后过期，以下方式保证可以在过期后自动获取到新的临时密钥。public class CustomQCloudCredentialProvider : DefaultSessionQCloudCredentialProvider{ // 这里假设开始没有密钥，也可以用初始的临时密钥来初始化 public CustomQCloudCredentialProvider(): base(null, null, 0L, null) { ; } public override void Refresh() { //… 首先通过腾讯云请求临时密钥 string tmpSecretId = "SECRET_ID"; //"临时密钥 SecretId", 临时密钥生成和使用指引参见 https://cloud.tencent.com/document/product/436/14048 string tmpSecretKey = "SECRET_KEY"; //"临时密钥 SecretKey", 临时密钥生成和使用指引参见 https://cloud.tencent.com/document/product/436/14048 string tmpToken = "COS_TOKEN"; //"临时密钥 token", 临时密钥生成和使用指引参见 https://cloud.tencent.com/document/product/436/14048 long tmpStartTime = 1546860702;//临时密钥有效开始时间，精确到秒 long tmpExpiredTime = 1546862502;//临时密钥有效截止时间，精确到秒 // 调用接口更新密钥 SetQCloudCredential(tmpSecretId, tmpSecretKey, String.Format("{0};{1}", tmpStartTime, tmpExpiredTime), tmpToken); }}QCloudCredentialProvider cosCredentialProvider = new CustomQCloudCredentialProvider();注意：由于临时密钥在一定时效后过期，这种方式在过期后会请求失败，不建议使用。string tmpSecretId = "SECRET_ID"; //"临时密钥 SecretId", 临时密钥生成和使用指引参见 https://cloud.tencent.com/document/product/436/14048string tmpSecretKey = "SECRET_KEY"; //"临时密钥 SecretKey", 临时密钥生成和使用指引参见 https://cloud.tencent.com/document/product/436/14048string tmpToken = "COS_TOKEN"; //"临时密钥 token", 临时密钥生成和使用指引参见 https://cloud.tencent.com/document/product/436/14048long tmpExpireTime = 1546862502;//临时密钥有效截止时间，精确到秒QCloudCredentialProvider cosCredentialProvider = new DefaultSessionQCloudCredentialProvider( tmpSecretId, tmpSecretKey, tmpExpireTime, tmpToken);string secretId = Environment.GetEnvironmentVariable("SECRET_ID"); //用户的 SecretId，建议使用子账号密钥，授权遵循最小权限指引，降低使用风险。子账号密钥获取可参见 https://cloud.tencent.com/document/product/598/37140string secretKey = Environment.GetEnvironmentVariable("SECRET_KEY"); //用户的 SecretKey，建议使用子账号密钥，授权遵循最小权限指引，降低使用风险。子账号密钥获取可参见 https://cloud.tencent.com/document/product/598/37140long durationSecond = 600; //每次请求签名有效时长，单位为秒QCloudCredentialProvider cosCredentialProvider = new DefaultQCloudCredentialProvider( secretId, secretKey, durationSecond);

七、初始化 CosXmlServer

使用 CosXmlConfig 与 QCloudCredentialProvider 初始化 CosXmlServer 服务类。服务类建议在程序中作为单例使用。

CosXml cosXml = new CosXmlServer(config, cosCredentialProvider);

八、访问 COS 服务

创建存储桶查询存储桶列表上传对象查询对象列表下载对象删除对象关于创建存储桶的完整示例，请前往 GitHub 查看。using COSXML;using COSXML.Auth;using COSXML.Model.Bucket;namespace COSXMLDemo{ public class CreateBucketModel { public CosXml cosXml; // 初始化COS服务实例 private void InitCosXml() { string region = Environment.GetEnvironmentVariable("COS_REGION");
