JSON formatting

The Arcus.WebApi.Hosting library provides a way to restrict and configure the JSON input and output formatting of your application. This allows for a easier and more secure formatting when working with JSON types.

Installation

These features require to install our NuGet package:

PM > Install-Package Arcus.WebApi.Hosting

Restricting JSON format

We have provided an extension that will allow you to restrict your input and output formatting to only JSON formatting (Only the SystemTextJsonInputFormatter will remain). This means that all other incoming content will result in UnsupportedMediaType failures and outgoing content will fail to serialize back to the sender. With this functionality, you'll be sure that you only have to deal with JSON.

Following example shows you how you can configure this:

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Mvc;

WebApplicationBuilder builder = WebApplication.CreateBuilder();

builder.Services.AddControllers(mvcOptions =>
{
    mvcOptions.OnlyAllowJsonFormatting();
});

Configure JSON format

We have provided an extension that will allow you to configure the input and output JSON formatting in one go. This means that any options you configure in this extension will automatically apply to the incoming model as well as the outgoing model. This makes the JSON formatting more streamlined and easier to maintain.

Following example shows you how you can configure these options:

using System.Text.Json.Serialization;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Mvc;

WebApplicationBuilder builder = WebApplication.CreateBuilder();

builder.Services.AddControllers(mvcOptions =>
{
    mvcOptions.ConfigureJsonFormatting(jsonOptions =>
    {
        jsonOptions.Converters.Add(new JsonStringEnumConverter());
    });
});
