【问题描述】:
我有一个带有一些模型和控制器的web api解决方案。
这是我的模型示例:
public class Category
{
[Key]
public int Id { get; set; }
[Required]
public string Name { get; set; }
}
这是他的控制者:
public class CategoriesController : ApiController
{
private FrigoWebServiceContext db = new FrigoWebServiceContext();
// GET: api/Categories
[HttpGet]
public string GetCategories()
{
return JsonConvert.SerializeObject(db.Categories.ToList());
}
// GET: api/Categories/5
[ResponseType(typeof(string))]
public string GetCategory(int id)
{
Category category = db.Categories.Find(id);
if (category == null)
{
return null;
}
string jsonCategory = JsonConvert.SerializeObject(category);
return jsonCategory;
}
protected override void Dispose(bool disposing)
{
if (disposing)
{
db.Dispose();
}
base.Dispose(disposing);
}
private bool CategoryExists(int id)
{
return db.Categories.Count(e => e.Id == id) > 0;
}
}
现在,这是配置:
config.Routes.MapHttpRoute(
name: "GetId",
routeTemplate: "api/{controller}/{id}"
//defaults: new { id = RouteParameter.Optional }
);
config.Routes.MapHttpRoute(
name: "GetAll",
routeTemplate: "api/{controller}"
//defaults: new { id = RouteParameter.Optional }
);
但是调用以下网站我什么也没收到
注意:我使用 IIS 发布了带有“myAppName”路径名的 api
- http://localhost/myAppName/Api/CategoriesController
- http://localhost/myAppName/Api/CategoriesController/0
- http://localhost/myAppName/Api/Category
- http://localhost/myAppName/Api/Category/0
- http://localhost/myAppName/Api/CategoriesController/GetCategories
- http://localhost/myAppName/Api/Category/GetCategories
- http://localhost/myAppName/Api/Categories
但这些都没有工作
这是错误:
错误 HTTP 404.0 - 未找到所需资源已被删除, 重命名或暂时不可用
我从互联网上看到了一些问题,我尝试使用它们,但我无法弄清楚为什么这不起作用。
任何帮助将不胜感激,这是我第一次使用 WebApi
这是我的 Web.Config

【问题讨论】:
-
/Api/Categories/ -
@AntP 感谢回复,但还是不行
-
我认为问题出在发布的代码之外
-
您确定 IIS 配置正确吗?
-
您的应用程序可以在本地机器上运行吗?
