在.Net Core 3.1Web API中创建返回响应码的通用函数

using Microsoft.AspNetCore.Mvc;

public static class ResponseHelper
{
    public static ActionResult CreateResponse(int statusCode, string message = null)
    {
        switch (statusCode)
        {
            case 200:
                return new OkObjectResult(message);
            case 400:
                return new BadRequestObjectResult(message);
            case 500:
                return new ObjectResult(message) { StatusCode = 500 };
            default:
                return new StatusCodeResult(statusCode);
        }
    }
}

[HttpGet]
public ActionResult Get()
{
    // 调用通用函数创建一个成功的响应对象
    return ResponseHelper.CreateResponse(200, "Success");
}

[HttpPost]
public ActionResult Post([FromBody] MyModel model)
{
    if (ModelState.IsValid)
    {
        // 处理请求逻辑

        // 调用通用函数创建一个自定义的响应对象
        return ResponseHelper.CreateResponse(200, "Data saved successfully");
    }
    else
    {
        // 调用通用函数创建一个错误的响应对象
        return ResponseHelper.CreateResponse(400, "Invalid data");
    }
}
