405不允许的方法上WebAPI2（OWIN） [英] 405 Method Not Allowed on WebAPI2 (OWIN)

问题描述

我建立的WebAPI端点我的API，但我有麻烦我AngularJS调用我的postRegister方法​​来工作。

I am setting up a WebAPI endpoint for my API, but am having trouble getting my AngularJS calls to my PostRegister method to work.

本的WebAPI和角度都在独立的站点。

The webAPI and Angular are on separate sites.

在Startup.cs我有：

On the Startup.cs I have:

    public void Configuration(IAppBuilder app)
    {
        ConfigureOAuth(app);

        var config = new HttpConfiguration();

        WebApiConfig.Register(config);
        app.UseCors(Microsoft.Owin.Cors.CorsOptions.AllowAll);
        app.UseWebApi(config);

    }

    private void ConfigureOAuth(IAppBuilder app)
    {
        var oAuthServerOptions = new OAuthAuthorizationServerOptions
        {
            AllowInsecureHttp = true,
            TokenEndpointPath = new PathString(Paths.TokenPath),
            AccessTokenExpireTimeSpan = TimeSpan.FromMinutes(30),
            Provider = Kernel.Get<IOAuthAuthorizationServerProvider>()
        };
        app.UseOAuthAuthorizationServer(oAuthServerOptions); 

        OAuthBearerOptions = new OAuthBearerAuthenticationOptions();
        app.UseOAuthBearerAuthentication(OAuthBearerOptions);
    }

然后在控制器上，我有我的方法，它被设置为允许匿名：

Then on the controller, I have my method that is set to allow anonymous:

    [AllowAnonymous]
    public bool PostRegister(UserSignupForm form)
    {
        ...
    }

我也更新了web.config中：

I've also updated the web.config:

 <system.webServer>
    <handlers>
      <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
      <remove name="OPTIONSVerbHandler" />
      <remove name="TRACEVerbHandler" />
      <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>
  </system.webServer>

在角边，我做一个简单的$ http.post电话：

On the Angular side, I make a simple $http.post call:

    saveRegistration: function (registration) {
        return $http.post(baseUrl + '/api/signup/register', registration).then(function (response) {
            return response;
        });
    }

使用邮差使得电话时，我得到一个成功的响应，但这样做的角一样打电话时，我得到的405错误。

When making the call using Postman, I get a successful response, but when doing the same call from Angular, I get the 405 error.

BitOfTech示例站点，发送相同的请求头，但是能够获得访问控制允许-XXX头

BitOfTech sample site, is sending the same request headers, but is able to get the Access-Control-Allow-XXX headers

我已经更新了我的code遵循<一个href=\"http://bitoftech.net/2014/06/01/token-based-authentication-asp-net-web-api-2-owin-asp-net-identity/\">Token使用ASP.NET的Web API基于2认证，Owin和身份

I've updated my code to follow Token Based Authentication using ASP.NET Web API 2, Owin, and Identity

推荐答案

最近，我有类似的问题。我添加控制器处理程序pre-飞行选项请求，并解决了这个问题。

I had similar issue recently. I added controller handler for the pre-flight OPTIONS request and it solved the problem.

[AllowAnonymous]
[Route("Register")]
[AcceptVerbs("OPTIONS")]
public async Task<IHttpActionResult> Register()
{
    return Ok();
}
