I was searching for a code snippet on how to upload a file to DO Spaces but cloud not found anything. After many attempts, I found the solution.
After downloading AWS SDK from nuget manager,
Upload Class:
public static class UploadFileMPUHighLevelAPITest
{
public static string bucketName = "your spaces name";
//public static string filePath = "d:\\test upload.txt";
public static string endpoingURL = "https://fra1.digitaloceanspaces.com";
public static IAmazonS3 s3Client;
public static bool UploadFile(string filePath, string fileName, string folderName)
{
var s3ClientConfig = new AmazonS3Config
{
ServiceURL = endpoingURL
};
s3Client = new AmazonS3Client(s3ClientConfig);
try
{
var fileTransferUtility = new TransferUtility(s3Client);
var fileTransferUtilityRequest = new TransferUtilityUploadRequest
{
BucketName = bucketName+ @"/" + folderName,
FilePath = filePath,
StorageClass = S3StorageClass.StandardInfrequentAccess,
PartSize = 6291456, // 6 MB
Key = fileName,
CannedACL = S3CannedACL.PublicRead
};
fileTransferUtility.Upload(fileTransferUtilityRequest);
return true;
}
catch (AmazonS3Exception e)
{
Console.WriteLine("Error encountered ***. Message:'{0}' when writing an object", e.Message);
}
catch (Exception e)
{
Console.WriteLine("Unknown encountered on server. Message:'{0}' when writing an object", e.Message);
if (e.Message.Contains("disposed"))
return true;
}
return false;
}
}
appsettings.json
"AWS": {
"AccessKey": "your access key",
"SecretKey": "your secret key"
}
Startup.cs
public void ConfigureServices(IServiceCollection services)
{
//enable cors
services.AddCors(c =>
{
c.AddPolicy("AllowOrigin", options => options.AllowAnyOrigin());
});
services.AddDbContext<onusshoppingContext>(options => options.UseMySql(Configuration.GetConnectionString("myContext")));
services.Configure<HostingDetails>(Configuration.GetSection("Hosting"));
services.Configure<AppSetting>(Configuration.GetSection("AppSetting"));
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
Environment.SetEnvironmentVariable("AWS_ACCESS_KEY_ID", Configuration["AWS:AccessKey"]);
Environment.SetEnvironmentVariable("AWS_SECRET_ACCESS_KEY", Configuration["AWS:SecretKey"]);
}
I hope it is useful!
