我的S3存储桶中有一个文件,我想通过Lambda函数访问该文件。
当我将此文件的路径传递给方法之一时,出现错误:
找不到路径'/var/task/https:/s3.amazonaws.com/TestBucket/testuser/AWS_sFTP_Key.pem”的一部分。
例如:
TestMethod("https://s3.amazonaws.com/TestBucket/testuser/AWS_sFTP_Key.pem")
代码:
public void FunctionHandler(S3Event s3Event, ILambdaContext lambdaContext)
{
ConnectionInfo connectionInfo = new ConnectionInfo("xxx.xxx.xx.xxx", "testuser",
new AuthenticationMethod[]{
new PrivateKeyAuthenticationMethod("testuser", new PrivateKeyFile[] {
new PrivateKeyFile("https://s3.amazonaws.com/TestBucket/testuser/AWS_sFTP_Key.pem")})
});
SftpClient sftpClient = new SftpClient(connectionInfo);
sftpClient.Connect();
lambdaContext.Logger.Log(sftpClient.WorkingDirectory);
sftpClient.Disconnect();
}
答案 0 :(得分:1)
您可以使用AWS SDK
来从S3读取文件,如下所示,但是我建议使用AWS Certificate Manager
或IAM
来存储和管理证书和密钥:
PS:确保为lambda函数或存储桶策略分配了适当的角色,以使存储桶能够从GetObject
S3
:
RegionEndpoint bucketRegion = RegionEndpoint.USWest2;//region where you store your file
client = new AmazonS3Client(bucketRegion);
GetObjectRequest request = new GetObjectRequest();
request.WithBucketName(BUCKET_NAME);//TestBucket
request.WithKey(S3_KEY);//testuser/AWS_sFTP_Key.pem
GetObjectResponse response = client.GetObject(request);
StreamReader reader = new StreamReader(response.ResponseStream);
String content = reader.ReadToEnd();
