如何在 WebApi 中使用多个 GET 操作？

Question

好吧，我实际上正在尝试学习 WebApi 并假设我有一个场景，我有两个这样的 get 方法

控制器

public class EmployeeApiController : ApiController
{
    public List<Student> GetAllStudents() { ... }

    public List<Student> EmailChange(string studentName, string Email) { ... }

    public List<Student> AddressChange(string studentName, string Address) { ... }
}

public class Student
{
    public string StudentName { get; set; }
    public string Address { get; set; }
    public string Email { get; set; }
    public static List<Student> students { get; set; }
}

我无法调用相应的方法，我该怎么做，我知道有很多博客，但它并没有帮助我了解如何真正访问这些方法。通过浏览几个博客，我制作了这样的整个代码

WebApiConfig 代码

public static void Register(HttpConfiguration config)
{
    config.MapHttpAttributeRoutes();

    config.Routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{action}/{id}",
        defaults: new { id = RouteParameter.Optional }
    );
}

控制器代码

    public List<Student> GetAllStudents()
    {
        Student.students = new List<Student> {
            new Student { StudentName="foo",Address="usa",Email="foo@yahoo.com"},
            new Student { StudentName="joe",Address="mumbai",Email="joe@yahoo.com"},
            new Student { StudentName="albert",Address="georgia",Email="albert@yahoo.com"},
            new Student { StudentName="prince",Address="missisipi",Email="prince@yahoo.com"}
        };
        return Student.students;
    }
    [HttpGet]
    public List<Student> UpdateEmail(string studentName, string Email)
    {
        return Student.students.Select(i =>
        {
            if (i.StudentName == studentName)
            {
                i.Email = Email;
            }
            return i;
        }).ToList();

    }
    [HttpGet]
    public List<Student> UpdateAddress(string studentName, string Address)
    {
        return Student.students.Select(x =>
        {
            if (x.StudentName == studentName)
            {
                x.Address = Address;
            }
            return x;
        }).ToList();
    }
}

public class Student
{
    public string StudentName { get; set; }
    public string Address { get; set; }
    public string Email { get; set; }
    public static List<Student> students { get; set; }
}

我对如何访问UpdateEmail 方法和UpdateAddress使用 GET 请求的方法有点困惑。

更新 1

当我这样打电话时

http://localhost:53711/api/EmployeeApi/UpdateAddress 或者

http://localhost:53711/api/EmployeeApi/UpdateEmail

我收到这样的错误

当我像这样打电话时，我收到一个错误

http://localhost:53711/api/EmployeeApi/UpdateEmail/foo/foo

要么将模板更改为routeTemplate: "api/{controller}/{action}/{studentName}"，并将方法保留为原样

public static void Register(HttpConfiguration config) {
    config.MapHttpAttributeRoutes();

    config.Routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{action}/{studentName}"
    );
}

或者

保持模板"api/{controller}/{action}/{id}"不变，即：并将方法参数更改为(string id,.......)

[HttpGet]
public List<Student> UpdateEmail(string id, string Email) { ... }

或者

您还可以放弃基于约定的路由并使用属性路由

[RoutePrefix("api/EmployeeApi")]
public class EmployeeApiController : ApiController
{
    //GET api/EmployeeApi
    [HttpGet]
    [Route("")]
    public List<Student> GetAllStudents() { ... }

    //GET api/EmployeeApi/EmailChange/foo/foo@email.com
    [HttpGet]
    [Route("EmailChange/{studentName}/{email}")]
    public List<Student> EmailChange(string studentName, string email) { ... }

    //GET api/EmployeeApi/AddressChange/foo/China
    [HttpGet]
    [Route("AddressChange/{studentName}/{address}")]
    public List<Student> AddressChange(string studentName, string Address) { ... }
}
