Use another server name for AWS blog storage #6446

carl.hallqvist created one year ago

ABP Framework version: v7.3.3
UI Type: Blazor WASM
Database System: EF Core SQL Server
Tiered (for MVC) or Auth Server Separated (for Angular): yes
Exception message and full stack trace:
Steps to reproduce the issue:

I am trying to use AWS blog storage, but since it is S3 object storage, I think it shall be possible to use it on S3 storage in other cloud providers (in my case DigitalOcean).

So I am trying to follow this one: https://docs.abp.io/en/abp/latest/Blob-Storing-Aws

And I have the following properties when using S3cmd:

access_key = DOxxxxxxxxxxxxxx
secret_key = Qpxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
check_ssl_certificate = True
check_ssl_hostname = True
host_base = fra1.digitaloceanspaces.com
host_bucket = %(bucket)s.fra1.digitaloceanspaces.com

I guess that it is the host_base that needs to be replaced from s3.amazonaws.com to digitaloceanspaces.com , but how can I do that? I can't find any properties that set that hostname.

Kind regards, Carl

You can try to override DefaultAmazonS3ClientFactory class to set additional properties, I'm not sure if it supports this. https://github.com/aws/aws-sdk-net

Thanks,

I think that will work out since it is possible to change host according to:

using System;
using Amazon;
using Amazon.S3;
using Amazon.S3.Model;

string accessKey = Environment.GetEnvironmentVariable("SPACES_KEY");
string secretKey = Environment.GetEnvironmentVariable("SPACES_SECRET");

AmazonS3Config config = new AmazonS3Config();
config.ServiceURL = "https://nyc3.digitaloceanspaces.com";

AmazonS3Client s3Client = new AmazonS3Client(
        accessKey,
        secretKey,
        config
        );

However, can you please show me how to override DefaultAmazonS3ClientFactory class? All I need is to override the public virtual async Task<AmazonS3Client> GetAmazonS3Client method, with two lines that explicit set the config.ServiceURL value from the example above.

Kind regards, Carl
