Configuring Blob Storing Using File system as the storage provider. #5131 | Support

ed_developer2 created one year ago

Hello,

I am trying to change the storage provider from default to file system, for which I am configuring AbpBlobStoringOptions in my HttpApiHost module, And i am storing the path in Abpsettings table and i want to access the path using ISettingProvider, but the problem is I can't Inject ISettingProvider in the constructor because the module requires a parameterless constructor to create the instance. so can you help me with providing a way to retrieve the path from the abpsettings table in my hostmodule.

Thank you.

Hi,

let me rephrase just to ensure that I understood your issue.

You want to use Blob Storage with the file system provider
Instead of setting a hardcoded base path (like described here https://docs.abp.io/en/abp/latest/Blob-Storing-File-System#configuration) you want to use a value which is determined at runtime

You can archieve that by implementing your own IBlobFilePathCalculator as described here: https://docs.abp.io/en/abp/latest/Blob-Storing-File-System#file-path-calculation

An example would look as follows:

using System.IO;
using Volo.Abp.BlobStoring;
using Volo.Abp.BlobStoring.FileSystem;
using Volo.Abp.Settings;

namespace app;

public class MyBlobFilePathCalculator : IBlobFilePathCalculator
{
    private readonly ISettingProvider _settingProvider;

    public MyBlobFilePathCalculator(ISettingProvider settingProvider)
    {
        _settingProvider = settingProvider;
    }

    public string Calculate(BlobProviderArgs args)
    {
        string basePath = _settingProvider.GetOrNullAsync("MySetting").Result;

        return Path.Combine(basePath, args.ContainerName, args.BlobName);
    }
}
