Create a Web Api using Minimal Api in .NET 6

#csharp #minimalapi #net6 #webapi

.NET 6 brings many language improvements in C# 10. Minimal Api is one such feature which allows to create a web api with less boilerplate code. Here is the example which uses Minimal Api for creating an AES Encryption and Decryption api.

using AESEncryptDecrypt;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

app.UseHttpsRedirection();

app.MapPost("/encrypt", (string value) =>
{
    string key = app.Configuration["AES:Key"];
    string iv = app.Configuration["AES:AES_IV"];
    return Results.Ok(AESEncDec.AESEncryption(value, key, iv));
});
app.MapPost("/decrypt", (string value) =>
{
    string key = app.Configuration["AES:Key"];
    string iv = app.Configuration["AES:AES_IV"];
    return Results.Ok(AESEncDec.AESDecryption(value, key, iv));
});

app.Run();
