.NET Framework HTTP servers Basic read-only HTTP file server (ASP.NET Core)
Example
1 - Create an empty folder, it will contain the files created in the next steps.
2 - Create a file named project.json with the following content (adjust the port number and rootDirectory as appropriate):
{
"dependencies": {
"Microsoft.AspNet.Server.Kestrel": "1.0.0-rc1-final",
"Microsoft.AspNet.StaticFiles": "1.0.0-rc1-final"
},
"commands": {
"web": "Microsoft.AspNet.Server.Kestrel --server.urls http://localhost:60000"
},
"frameworks": {
"dnxcore50": { }
},
"fileServer": {
"rootDirectory": "c:\\users\\username\\Documents"
}
}
3 - Create a file named Startup.cs with the following code:
using System;
using Microsoft.AspNet.Builder;
using Microsoft.AspNet.FileProviders;
using Microsoft.AspNet.Hosting;
using Microsoft.AspNet.StaticFiles;
using Microsoft.Extensions.Configuration;
public class Startup
{
public void Configure(IApplicationBuilder app)
{
var builder = new ConfigurationBuilder();
builder.AddJsonFile("project.json");
var config = builder.Build();
var rootDirectory = config["fileServer:rootDirectory"];
Console.WriteLine("File server root directory: " + rootDirectory);
var fileProvider = new PhysicalFileProvider(rootDirectory);
var options = new StaticFileOptions();
options.ServeUnknownFileTypes = true;
options.FileProvider = fileProvider;
options.OnPrepareResponse = context =>
{
context.Context.Response.ContentType = "application/octet-stream";
context.Context.Response.Headers.Add(
"Content-Disposition",
$"Attachment; filename=\"{context.File.Name}\"");
};
app.UseStaticFiles(options);
}
}
4 - Open a command prompt, navigate to the folder and execute:
dnvm use 1.0.0-rc1-final -r coreclr -p
dnu restore
Note:
These commands need to be run only once.
Use dnvm list to check the actual number of the latest installed version of the core CLR.
5 - Start the server with: dnx web. Files can now be requested at http://localhost:60000/path/to/file.ext.
For simplicity, filenames are assumed to be all ASCII (for the filename part in the Content-Disposition header) and file access errors are not handled.
