“所请求的资源不支持http方法'OPTIONS'”；使用EnableCors时 [英] "The requested resource does not support http method 'OPTIONS'" when using EnableCors

问题描述

我想对Asp.net Web Api中的一项特定操作启用CORS。这是我尝试执行的操作：

I want to enable CORS on one specific action in an Asp.net Web Api. Here's how I'm trying to do it:

[Route("api/mycontroller/myaction")]
[HttpPost]
[EnableCors("https://example.com", "*", "post")]
public async Task<IHttpActionResult> MyAction()
{
    ...
}

但是当我向路由发送OPTIONS请求时，我得到一个错误：请求的资源不支持http方法'OPTIONS'。我也尝试删除[HttpPost]批注无济于事。
我缺少了什么？

But when I send an OPTIONS request to the route, I get back an error: "The requested resource does not support http method 'OPTIONS'." I also tried removing the [HttpPost] annotation to no avail. What am I missing?

推荐答案

您可能错过了对的更高级别的致电HttpConfiguration.EnableCors ，如此处所述： https://enable-cors.org /server_aspnet.html 。

You've probably missed the higher level call to HttpConfiguration.EnableCors, as described here: https://enable-cors.org/server_aspnet.html.

将此代码添加到您的配置中：

Add this code to your configuration:

public static void Register(HttpConfiguration config)
{
    // New code
    config.EnableCors();
}
