This project created as a backend part for the file manager app.
Here is the fronend part. (The frontend application does not support backend with version >=2.0.0)
The application is built using the CQRS pattern and MediatR library to manage command and request handlers.
Nuget: PM> Install-Package f14.AspNetCore.FileManager
First off all learn the format.
- Add a services:
using f14.AspNetCore.FileManager; // Add namespace
public void ConfigureServices(IServiceCollection services)
{
// Adds all default handlers as services.
services.AddMediatR(typeof(FileManagerAssemblyBeacon).Assembly);
}- Then you need use it in your controller which used for handling request from a file manager:
// Your controller for file manager
public class FileManagerController : Controller
{
private IMediator _mediator;
_ public FileManagerController(IMediator mediator)
{
_mediator = mediator;
}
// Method to handler request from fronend
[HttpPost]
public async Task<IActionResult> CreateFolder(CreateCommand command)
{
try
{
var r = await _mediator.Send(command);
return Ok(); // Or what you need
}
catch (Exception ex)
{
// log errors
return BadRequest(); // Or what you need
}
}
}Do the same thing for the other operation handlers.
CopyCommand - for copy files and folders.
MoveCommand - for move files and folders.
CreateCommand - for create folders.
DeleteCommand - for delete files and folders.
RenameCommand - for rename files and folders.
GetFolderStructureQuery - for receiving file system map.
To overwrite the default handlers, you need to use the default method provided by the Asp.Net Core DI container.
public class Startup
{
[Fact]
public void ConfigureServices(IServiceCollection services)
{
services.AddMediatR(typeof(FileManagerAssemblyBeacon).Assembly);
// Call your overwrite code after calling the AddMediatR().
services.Replace(new ServiceDescriptor(typeof(IRequestHandler<CreateCommand, CreateCommandResult>), typeof(CustomCreateHandler), ServiceLifetime.Transient));
}
... Caustom handler
public class CustomCreateHandler : IRequestHandler<CreateCommand, CreateCommandResult>
{
public Task<CreateCommandResult> Handle(CreateCommand request, CancellationToken cancellationToken)
{
throw new NotImplementedException();
}
}
}
