对于有效的请求，Web API会引发“提供的参数数量错误”(Web API throws “The number of provided parameters is wrong” for valid Request)

我有一个Web API控制器，其中包含以下方法;

[AllowAnonymous] [HttpPost] [Route("testing")] public Token Testing(string username, string password, string companyName, string groupName, bool acceptedTerms)

这在我的VS 2015本地工作，而不是在远程IIS（Windows Server 2012 R2，IIS 8.5）上工作。

我得到的错误是;

The number of provided parameters for method 'Company.API.Controllers.UserController.Testing' is wrong. Parameter name: parameters

抛出此错误的URL具有所有必需参数; HTTP：//主机/测试username=user@gmail.com&password=qwertyui&companyName=XYZ&groupName=ABC&acceptedTerms=true

I've a Web API Controller which has following method in it;

[AllowAnonymous] [HttpPost] [Route("testing")] public Token Testing(string username, string password, string companyName, string groupName, bool acceptedTerms)

This is working locally on my VS 2015 and not working on the Remote IIS (Windows Server 2012 R2, IIS 8.5).

The error I'm getting is;

The number of provided parameters for method 'Company.API.Controllers.UserController.Testing' is wrong. Parameter name: parameters

The URL which throws this error has all the required parameters; http://host/testing?username=user@gmail.com&password=qwertyui&companyName=XYZ&groupName=ABC&acceptedTerms=true

我已通过为Application Pool设置Enable 32-Bit Applications为True来解决此问题; 但我仍然不确定为什么会这样。 有关此的任何更多信息非常感谢。

I have fixed this issue by setting Enable 32-Bit Applications to True for the Application Pool; but I'm still not sure why this happens. Any more information on this is highly appreciated.
