阿里雲Oss對象存儲

將文件保存到阿里雲上。

1.添加對象存儲OSS空間 (新建Bucket)

能夠在阿里雲後臺對象存儲裏面添加，也能夠經過api添加。添加以後設置權限。

 

skd使用。

1安裝 Aliyun.OSS.SDK (framework版，若是須要能夠選擇core版)

2.初始化。

在存儲空間概覽頁面找到 EndPoint。

 

在設置appid和密鑰

 

 

const string accessKeyId = "<your AccessKeyId>";

const string accessKeySecret = "<your AccessKeySecret>";

const string endpoint = "http://oss-cn-hangzhou.aliyuncs.com";

• /// <summary>
• /// 由用戶指定的OSS訪問地址、阿里雲頒發的AccessKeyId/AccessKeySecret構造一個新的OssClient實例。
• /// </summary>
• /// <param name="endpoint">OSS的訪問地址。</param>
• /// <param name="accessKeyId">OSS的訪問ID。</param>
• /// <param name="accessKeySecret">OSS的訪問密鑰。</param>
• var ossClient = new OssClient(endpoint, accessKeyId, accessKeySecret);

3.上傳文件

 

// 初始化OssClient
var client = new OssClient(endpoint, accessKeyId, accessKeySecret);
try
{
    string fileToUpload = "your local file path";
    client.PutObject(bucketName, key, fileToUpload);
    Console.WriteLine("Put object succeeded");
}
catch (Exception ex)
{
    Console.WriteLine("Put object failed, {0}", ex.Message);
}

上傳本地文件

 

// 初始化OssClient
var client = new OssClient(endpoint, accessKeyId, accessKeySecret)
try
{
    string str = "a line of simple text";
    byte[] binaryData = Encoding.ASCII.GetBytes(str);            
    MemoryStream requestContent = new MemoryStream(binaryData);
    client.PutObject(bucketName, key, requestContent);
    Console.WriteLine("Put object succeeded");
}
catch (Exception ex)
{
    Console.WriteLine("Put object failed, {0}", ex.Message);
}

上傳文件（byte[],stream等）

其中key是要上傳的文件名（能夠要後綴也能夠不要）

 

 

4.訪問文件

 

OssClient client = new OssClient(endpoint, accessKeyId, accessKeySecret);
    var listResult = client.ListObjects(bucketName);
    foreach (var summary in listResult.ObjectSummaries)
    {   
        Console.WriteLine(summary.Key);
    }

5.刪除文件

 

OssClient client = new OssClient(endpoint, accessKeyId, accessKeySecret); client.DeleteObject(bucketName, key)
