RSCG – Refit
 
 

Generates code for retrieving data from HTTP API

This is how you can use Refit .

The code that you start with is

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net7.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Refit" Version="7.0.0" />
  </ItemGroup>
	 <PropertyGroup>
        <EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
        <CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
    </PropertyGroup>

</Project>

The code that you will use is

Console.WriteLine("Hello,World!");
var gitHubApi = RestService.For<IFindPosts>("https://jsonplaceholder.typicode.com/");
var data = await gitHubApi.GetPost(1);
Console.WriteLine(data.Title);

namespace RefitDemo;

public record Post
{
    public int Id { get; set; }
    public string Title { get; set; }
}

namespace RefitDemo;
public interface IFindPosts
{
    [Get("/posts/{nr}")]
    Task<Post> GetPost(long nr);
}

The code that is generated is
