C# 操作阿里云OSS资源上传

C#调用阿里云OSS SDK上传文件

在C#中使用阿里云OSS SDK上传资源到阿里云对象存储（OSS）可以通过以下步骤实现。首先，确保已经安装阿里云OSS SDK。你可以使用NuGet包管理器或者.NET CLI执行安装：

dotnet add package Aliyun.SDK.OSS

或者通过NuGet包管理器控制台执行：

Install-Package Aliyun.SDK.OSS

然后，你可以使用以下示例代码上传资源：

using System;
using System.IO;
using Aliyun.OSS;
using Aliyun.OSS.Common;

class Program
{
    static void Main()
    {
        // 阿里云账号 Access Key ID 和 Access Key Secret
        string accessKeyId = "YourAccessKeyId";
        string accessKeySecret = "YourAccessKeySecret";

        // 创建 OSS 客户端实例
        var client = new OssClient("YourEndpoint", accessKeyId, accessKeySecret);

        // 上传文件
        string bucketName = "YourBucketName";
        string objectKey = "YourObjectName";
        string localFilePath = "PathToLocalFile";

        try
        {
            using (var fs = File.Open(localFilePath, FileMode.Open))
            {
                var metadata = new ObjectMetadata();
                var result = client.PutObject(bucketName, objectKey, fs, metadata);
                Console.WriteLine($"ETag: {result.ETag}");
            }

            Console.WriteLine("File uploaded successfully.");
        }
        catch (OssException ex)
        {
            Console.WriteLine($"Failed to upload file. Error code: {ex.ErrorCode}, Message: {ex.Message}");
        }
        catch (Exception ex)
        {
            Console.WriteLine($"An unexpected error occurred: {ex.Message}");
        }
    }
}

请注意替换代码中的以下信息：

YourAccessKeyId 和 YourAccessKeySecret：你的阿里云账号的 Access Key ID 和 Access Key Secret。
YourEndpoint：你的 OSS 服务的 endpoint，如 http://oss-cn-hangzhou.aliyuncs.com。
YourBucketName：要上传到的存储桶的名称。
YourObjectName：上传到OSS的对象名称。
PathToLocalFile：本地文件的路径。

如果你希望上传文件夹中的所有资源到阿里云OSS，你可以使用Directory.GetFiles方法获取文件夹中的所有文件，然后循环上传每个文件。以下是一个示例代码：

using System;
using System.IO;
using System.Linq;
using Aliyun.OSS;
using Aliyun.OSS.Common;

class Program
{
    static void Main()
    {
        // 阿里云账号 Access Key ID 和 Access Key Secret
        string accessKeyId = "YourAccessKeyId";
        string accessKeySecret = "YourAccessKeySecret";

        // 创建 OSS 客户端实例
        var client = new OssClient("YourEndpoint", accessKeyId, accessKeySecret);

        // 上传文件夹中的所有资源
        string bucketName = "YourBucketName";
        string folderPath = "PathToLocalFolder";

        try
        {
            var files = Directory.GetFiles(folderPath);

            foreach (var filePath in files)
            {
                var objectKey = Path.GetFileName(filePath);

                using (var fs = File.Open(filePath, FileMode.Open))
                {
                    var metadata = new ObjectMetadata();
                    var result = client.PutObject(bucketName, objectKey, fs, metadata);
                    Console.WriteLine($"Uploaded {objectKey}. ETag: {result.ETag}");
                }
            }

            Console.WriteLine("All files uploaded successfully.");
        }
        catch (OssException ex)
        {
            Console.WriteLine($"Failed to upload files. Error code: {ex.ErrorCode}, Message: {ex.Message}");
        }
        catch (Exception ex)
        {
            Console.WriteLine($"An unexpected error occurred: {ex.Message}");
        }
    }
}

Unity中使用Oss Sdk上传资源

将Aliyun.OSS放到Unity的plugins文件夹下

  public  class OSSFolderUploaderEditor: EditorWindow
    {
        // 在Inspector窗口中设置你的OSS信息
        public  string accessKeyId = "YourAccessKeyId";
        public  string accessKeySecret = "YourAccessKeySecret";
        public  string endpoint = "https://oss-cn-shanghai.aliyuncs.com";
        public  string bucketName = "YourBucketName";
        public  string ossDirectory = "YourossDirectory /{0}/StreamingAssets"; // 目标目录
        // 设置本地文件夹路径
        string localFolderPath = "";

        private void OnGUI()
        {
            if (GUILayout.Button("上传资源"))
            {
                Start();
            }
        }

        public  void Start()
        {
            Debug.Log("开始上传");
            // 初始化OSS客户端
            var config = new ClientConfiguration();
            var client = new OssClient(endpoint, accessKeyId, accessKeySecret, config);

            long size = 0;
            // 获取文件夹中的所有文件
            string[] filePaths = Directory.GetFiles(localFolderPath);

            foreach (var filePath in filePaths)
            {
                // 获取文件名
                string objectKey = ossDirectory + "/" + Path.GetFileName(filePath);

                // 打开文件并将其内容读取到Stream
                using (FileStream fs = new FileStream(filePath, FileMode.Open))
                {
                    size += fs.Length;
                    // 创建上传请求
                    var putObjectRequest = new PutObjectRequest(bucketName, objectKey, fs);

                    try
                    {
                        // 执行上传
                        client.PutObject(putObjectRequest);
                        Debug.Log("File uploaded successfully: " + objectKey);
                    }
                    catch (OssException ex)
                    {
                        Debug.LogError("Failed to upload file. Error: " + ex.ErrorCode + " - " + ex.Message);
                    }
                    catch (System.Exception ex)
                    {
                        Debug.LogError("Failed to upload file. Error: " + ex.Message);
                    }
                }
               
            }
            Debug.Log($"资源上传完成:{TextFromBytesSize(size)}");
        }

        public string GetPlatformName(BuildTarget buildTarget)
        {
            switch (buildTarget)
            {
                case BuildTarget.Android:
                    return "Android";
                case BuildTarget.iOS:
                    return "IOS";
                default:
                    return "PC";
            }
        }
        public string TextFromBytesSize(long size_num)
        {
            long data_size = size_num;
            if (data_size < 1024)

            }
            data_size /= 1024;
            if (data_size / 1024 < 1024)

        }
