将文件保存到阿里云上。
1.添加对象存储OSS空间 (新建Bucket)
可以在阿里云后台对象存储里面添加,也可以通过api添加。添加之后设置权限。
skd使用。
1安装 Aliyun.OSS.SDK (framework版,如果需要可以选择core版)
2.初始化。
在存储空间概览页面找到 EndPoint。
在设置appid和密钥
const string accessKeyId = "<your AccessKeyId>";
const string accessKeySecret = "<your AccessKeySecret>";
const string endpoint = "http://oss-cn-hangzhou.aliyuncs.com";
/// <summary>
/// 由用户指定的OSS访问地址、阿里云颁发的AccessKeyId/AccessKeySecret构造一个新的OssClient实例。
/// </summary>
/// <param name="endpoint">OSS的访问地址。</param>
/// <param name="accessKeyId">OSS的访问ID。</param>
/// <param name="accessKeySecret">OSS的访问密钥。</param>
var ossClient = new OssClient(endpoint, accessKeyId, accessKeySecret);
3.上传文件
// 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);
}
上传本地文件
// 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);
}
上传文件(byte[],stream等)
其中key是要上传的文件名(可以要后缀也可以不要)
4.访问文件
OssClient client = new OssClient(endpoint, accessKeyId, accessKeySecret);
var listResult = client.ListObjects(bucketName);
foreach (var summary in listResult.ObjectSummaries)
{
Console.WriteLine(summary.Key);
}
5.删除文件
OssClient client = new OssClient(endpoint, accessKeyId, accessKeySecret);
client.DeleteObject(bucketName, key)
