Basic usage

Model validation

public class Function1 : HttpFunctionBase
{
    public Function1(IHttpContextAccessor httpContextAccessor)
        : base(httpContextAccessor)
    {
    }

    [FunctionName("Function1")]
    public IActionResult Run(
        [HttpTrigger(AuthorizationLevel.Function, "post")]
        SampleModel model,
        ILogger log)
    {
        if (!TryValidateModel(model))
        {
            return BadRequest(ModelState);
        }

        return Ok(model);
    }
}

public class SampleModel
{
    [Required]
    public string Name { get; set; }

    public string[] Array { get; set; }

    [Range(100, 10000)]
    public int Price { get; set; }
}

ASP.NET Core like helpers

public class Function2 : HttpFunctionBase
{
    public Function2(IHttpContextAccessor httpContextAccessor)
        : base(httpContextAccessor)
    {
    }

    [FunctionName("Function2")]
    public IActionResult Run(
        [HttpTrigger(AuthorizationLevel.Function, "get")]
        HttpRequest req,
        ILogger log)
    {
        Response.Headers.Add("Cache-Control", "no-cache");

        return Ok($"Now: {DateTime.Now}");
    }
}

Support URL generation

public class Function3 : HttpFunctionBase
{
    public Function3(IHttpContextAccessor httpContextAccessor)
        : base(httpContextAccessor)
    {
    }

    [FunctionName("Function3")]
    public IActionResult Run(
        [HttpTrigger(AuthorizationLevel.Function, "get", Route = "route/{id}")]
        HttpRequest req,
        string id,
        ILogger log)
    {
        return CreatedAtFunction("Function3", new { id = "kazuakix" }, null);
    }
}

Handle static files

public class Function1 : HttpFunctionBase
{
    public Function1(IHttpContextAccessor httpContextAccessor)
        : base(httpContextAccessor)
    {
    }

    [FunctionName("Function1")]
    public IActionResult Run(
        [HttpTrigger(AuthorizationLevel.Function, "get")] HttpRequest req,
        ILogger log)
    {
        return File("sample.html");
    }
}
