问题描述

我在 WebApi 2 应用程序中集成了 swagger.当应用程序具有单个控制器时，它可以正常工作.当我在应用程序中添加第二个控制器时.我收到以下错误:

I have integrated swagger in WebApi 2 application. It works fine when application has single controller. When I added second controller in the application. I got following error :

在第二个控制器中，我添加了以下两种方法.

In the second controller I have added following two methods.

 string Get(string username, string password);

 string Get(string credential);

如果我评论其中一种方法.然后就可以正常使用了.

If I comment one of the method. Then it works fine.

知道怎么解决吗?

推荐答案

在AppStart/SwaggerConfig.cs文件中

第一个，必须导入Linq

using System.Linq;

并在同一个文件中添加这一行

And add in the same file, this line

c.ResolveConflictingActions(apiDescriptions => apiDescriptions.First());

就在里面:

GlobalConfiguration.Configuration 
                .EnableSwagger(c =>
                    { ...

一个考虑:在您的控制器中，您必须使用 Http 方法:

One consideration: In your controllers, you must use the Http methods :

[HttpGet]
[Route("something")]
public List<model> something(){....}

[HttpGet]
[Route("something2")]
public List<model2> something2(){....}

[HttpPost]
[Route("mypost1")]
public List<model> mypost1(){....}

[HttpPost]
[Route("mypost2")]
public List<model2> mypost2(){....}
