MVC 6 多个获取方法

本文关键字:获取 方法 MVC | 更新日期: 2023-09-27 18:30:42

我正在尝试支持每个控制器的多个Get()方法,以及仅通过Web API访问的特别命名的方法。我已经在 MVC 5 中完成了此操作,但似乎无法弄清楚在 MVC 6 中是如何完成的。有什么想法吗?谢谢。

MVC 6 多个获取方法

不能有多个具有相同 url 模式的 Get 方法。您可以使用属性路由并为不同的 URL 模式设置多个 GET 方法。

[Route("api/[controller]")]
public class IssuesController : Controller
{
    // GET: api/Issues
    [HttpGet]
    public IEnumerable<string> Get()
    {
        return new string[] { "item 1", "item 2" };
    }
    // GET api/Issues/5
    [HttpGet("{id}")]
    public string Get(int id)
    {
        return "request for "+ id;
    }
    // GET api/Issues/special/5
    [HttpGet("special/{id}")]
    public string GetSpecial(int id)
    {
        return "special request for "+id;
    }
    // GET another/5
    [HttpGet("~/another/{id}")]
    public string AnotherOne(int id)
    {
        return "request for AnotherOne method with id:" + id;
    }
    // GET api/special2/5
    [HttpGet()]
    [Route("~/api/special2/{id}")]
    public string GetSpecial2(int id)
    {
        return "request for GetSpecial2 method with id:" + id;
    }
}

您可以看到我同时使用了HttpGetRoute属性来定义路由模式。

通过上述配置,您将获得以下响应

请求网址 : 您的网站/api/问题/

结果["value1","value2"]

请求网址 : yoursite/api/issues/4

结果request for 4

请求网址 : yoursite/api/special2/6

结果request for GetSpecial2 method with id:6

请求网址 : 您的网站/另一个/3

结果request for AnotherOne method with id:3

您可以使用属性路由链接 -

[Route("api/[controller]")] /* this is the defualt prefix for all routes, see line 20 for overridding it */
public class ValuesController : Controller
{
    [HttpGet] // this api/Values
    public string Get()
    {
        return string.Format("Get: simple get");
    }
    [Route("GetByAdminId")] /* this route becomes api/[controller]/GetByAdminId */
    public string GetByAdminId([FromQuery] int adminId)
    {
        return $"GetByAdminId: You passed in {adminId}";
    }
    [Route("/someotherapi/[controller]/GetByMemberId")] /* note the / at the start, you need this to override the route at the controller level */
    public string GetByMemberId([FromQuery] int memberId)
    {
        return $"GetByMemberId: You passed in {memberId}";
    }
    [HttpGet]
    [Route("IsFirstNumberBigger")] /* this route becomes api/[controller]/IsFirstNumberBigger */
    public string IsFirstNumberBigger([FromQuery] int firstNum, int secondNum)
    {
        if (firstNum > secondNum)
        {
            return $"{firstNum} is bigger than {secondNum}";
        }
        return $"{firstNum} is NOT bigger than {secondNum}";
    }
}
