C# 代碼實作上傳圖檔或視訊檔案到OSS

注意：記得引進Oss 相關的SDK,一般直接從Nuget包引入就行

private static string endpoint = "";//OSS通路域名
        private static string accessKeyId = "";//OSS密鑰
        private static string accessKeySecret = "";//OSS密鑰
        private static string returnUrl = "";//上傳傳回位址
        private static string bucketName = "";//存儲空間
        
        //imgstream：上傳檔案或視訊檔案流
        //name：檔案辨別名
        //path：存儲空間名
        public static string UpToAliYunImgage(Stream imgstream, string name, string path = "")
        {
            if (imgstream == null)
            {
                return "";
            }
            try
            {
                var key = name;
                if (!string.IsNullOrWhiteSpace(path))
                {
                    key = path + "/" + key;
                }
                OssClient oss = new OssClient(endpoint, accessKeyId, accessKeySecret);
                imgstream.Position = 0;
                oss.PutObject(bucketName, key, imgstream);
                //ObjectMetadata oa = new ObjectMetadata();
                //oa.AddHeader("Content-Disposition", "attachment");//設定oss檔案為強制下載下傳
                //oss.PutObject(bucketName, key, imgstream, oa);
                imgstream.Dispose();//上傳完記得釋放檔案流
                return returnUrl + key;
            }
            catch (Exception e)
            {
                return "";
            }
        }
