如何在ASP.NET MVC中启用跨源请求 [英] How to enable cross origin requests in ASP.NET MVC

问题描述

我正在尝试创建一个可在MVC 5中使用跨域请求(CORS)的Web应用程序.我已经尝试了所有操作，但没有任何结果.

I am trying to create a web application which works with cross-origin requests (CORS) in MVC 5. I have tried everything without any result.

具有属性

public class AllowCrossSiteJsonAttribute: ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
            filterContext.RequestContext.HttpContext.Response.AddHeader("Access-Control-Allow-Origin", "*");

        base.OnActionExecuting(filterContext);
    }
}

具有EnableCors属性

 [EnableCors("*")]

什么都没做，我开始认为这是不可能的

Nothing works I'm starting to think that it is impossible

推荐答案

要启用跨域请求，请将[EnableCors]属性添加到Web API控制器或控制器方法:

To enable cross-origin requests, add the [EnableCors] attribute to your Web API controller or controller method:

[EnableCors(origins: "http://systematixindia.com", headers: "*", methods: "*")]
public class TestController : ApiController
{
   // Controller method`enter code here`s not shown...
}
