[英]Apple Store Connect Api http request returns error 404 not found
[英]Preflight request returns 404 Not Found for Controllers in an Area
我有一个 WebAPI 项目,并且按照以下步骤启用了 CORS:
Install-Package Microsoft.AspNet.WebApi.Cors
。config.EnableCors();
到 WebApiConfig.cs。[EnableCors(origins: "*", headers: "*", methods: "*")]
到我的控制器。我的控制器位于根 Controllers 文件夹和区域内。
/Controllers/ValuesController
/Areas/TestArea/Controllers/OtherStuffController
两个控制器都有[EnableCors(...)]
属性。
我的问题是只有ValuesController
有效。
使用 Fiddler 检查对OtherStuffController
的请求,我可以看到客户端发送了一个预检 OPTIONS 请求,但服务器响应 404 not found 而不是 200 OK,但ValuesController
工作正常。
我究竟做错了什么? 为什么 TestArea 区域中的控制器不能处理 CORS 请求,而 Values 控制器可以?
这两个控制器除了名字没有什么不同,而且是在一个区域内。
附加信息
路线:
// In WebApiConfig.cs
config.Routes.MapHttpRoute("DefaultApi", "{controller}/{id}",
new {id = RouteParameter.Optional} );
// In Areas/TestArea/TestAreaAreaRegistration.cs
context.MapRoute("TestArea_default","TestArea/{controller}/{id}",
new {id = UrlParameter.Optional});
我用来访问操作方法的 URL:
http://localhxst:57578/values
http://localhxst:57578/testarea/otherstuff

值控制器.cs
namespace MyAPIApp.PublicAPI.Controllers
{
[EnableCors(origins: "*", headers: "*", methods: "*")]
[Authorize]
public class ValuesController : ApiController
{
private static readonly List<string> values = new List<string> { "ABC", "DEF" };
public IEnumerable<string> Get() { return values; }
}
}
OtherStuffController.cs
namespace MyAPIApp.PublicAPI.Areas.TestArea.Controllers
{
[EnableCors(origins: "*", headers: "*", methods: "*")]
[Authorize]
public class OtherStuffController : ApiController
{
private static readonly List<string> values = new List<string> { "ABC", "DEF" };
public IEnumerable<string> Get() { return values; }
}
}
我找到了问题所在。
当您通过添加 > 区域上下文菜单在项目中创建区域时,Visual Studio 会使用以下代码使用区域注册模板创建区域:
public override void RegisterArea(AreaRegistrationContext context) {
context.MapRoute(
"TestArea_default",
"TestArea/{controller}/{id}",
new {id = UrlParameter.Optional}
);
}
但是,此代码不适用于 ApiController。 正确的路由注册码是:
public override void RegisterArea(AreaRegistrationContext context) {
context.Routes.MapHttpRoute(
"TestArea_default",
"TestArea/{controller}/{id}",
new { id = RouteParameter.Optional });
}
事实证明,这与 CORS 无关。
我通过删除configuration\\system.webServer\\handlers
下的Web.config
文件中的以下行来解决此问题:
<remove name="OPTIONSVerbHandler" />
