如何从外部访问控制器 [英] How to access a controller from outside

问题描述

大家好，



感谢支持。我创建了一个Web API 2项目并在其中添加了一个控制器，并添加了几个带有HTTPGet属性的方法。如果我尝试从邮递员客户端访问该方法，它正常工作。但是，如果我试图从其他应用程序访问它们，我将遇到跨域原因问题。请帮我解决这个问题。



我尝试了什么：



我添加了config.EnableCors（）;在webapiconfig文件中。现在，我可以从外面访问api控制器。但是，控制器我添加了[EnableCors（*，*，*）]这个控制器的顶部。但是，它没有用。

解决方案

Hello everyone,

Thanks to support. I have created a Web API 2 Project and added a controller inside and added few methods with HTTPGet attributes. If i try to access that method from postman client it's working properly. But, If i tries to access them from other apps, I'm getting cross domain origin issue. Please help me to fix this issue.

What I have tried:

I have added config.EnableCors(); in webapiconfig file. Now, I can access api controllers from out side. But, Controllers i have added [EnableCors("*", "*", "*")] this one top of controller. But, It's not working.
