AutomaticApi

AutomaticApi can automatically generate APIs based on services, just define a REST API interface.

Quick start

1. Write service code

public class DemoService
{
    public string Get()
    {
        return "Hello AutomaticApi";
    }
}

2. Define the exposed REST API interface we want

public interface IDemoAService : IAutomaticApi
{
    /// <summary>
    /// DemoA api
    /// </summary>
    /// <returns></returns>
    string Get();
}

We can also define another REST API interface.

public interface IDemoBService : IAutomaticApi
{
    /// <summary>
    /// DemoB api
    /// </summary>
    /// <returns></returns>
    string Get();
}

And implement these interfaces.

public class DemoService : IDemoAService, IDemoBService
...

3. Configure Services

public void ConfigureServices(IServiceCollection services)
{
    services.AddAutomaticApi(op =>
    {
        op.AddApi<IDemoAService, DemoService>(); //only generate IDemoAService

        op.AddApi<DemoService>(); //Generate all api interface in DemoService 

        op.AddAssembly(Assembly.GetEntryAssembly()); //Generate all api interface in Assembly
    });
}

What a REST api interface?

You can totally use it as a controller.

public interface IDemoService : IAutomaticApi
{
    /// <summary>
    /// DemoB api
    /// </summary>
    /// <returns></returns>
    [Authorize]
    [HttpPost]
    [Route("...")]
    string UpdateAsync(Guid id, [FromBody] RequestModel model);
}

However, [HttpPost] [Route] usually doesn't need to be defined. AutomaticApi will generates Route and HttpMethod based on the Method name.

As we all know, some [Attrbute] may can't put it on interface like this.

[Authorize]
public interface IDemoService : IAutomaticApi
...

We can do some customization.

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Interface | AttributeTargets.Method, AllowMultiple = true, Inherited = true)]
public class MyAuthorizeAttribute : AuthorizeAttribute
{
}
