CORS的PUT支持和配合的ASP.NET Web API DELETE [英] CORS support for PUT and DELETE with ASP.NET Web API

问题描述

我用的ASP.NET Web API的最终版本着手实施一个JavaScript友好的API。每各种教程，我在我的web.config启用CORS：

I am working with the final version of ASP.NET Web API to implement a JavaScript-friendly API. Per various tutorials, I have enabled CORS in my web.config:

<system.webServer>
 <httpProtocol>
  <customHeaders>
    <add name="Access-Control-Allow-Origin" value="*" />
    <add name="Access-Control-Allow-Headers" value="Content-Type" />
  </customHeaders>
 </httpProtocol>
</system.webServer>

有了上面，跨域GET和POST请求做工精细，但PUT和DELETE请求都失败。

With the above, cross-domain GET and POST requests work fine, but PUT and DELETE requests both fail.

在Chrome浏览器：

In Chrome:

put方法不被访问控制允许的方法允许的。

Method PUT is not allowed by Access-Control-Allow-Methods.

方法Delete没有被访问控制允许的方法允许的。

Method DELETE is not allowed by Access-Control-Allow-Methods.

有没有得到PUT和DELETE动词工作跨域需要额外的东西？

Is there something additional required to get PUT and DELETE verbs working cross-domain?

推荐答案

看起来又增加自定义头整理出来：

It looks like adding another custom header sorted it out:

<system.webServer>
 <httpProtocol>
  <customHeaders>
    <add name="Access-Control-Allow-Origin" value="*" />
    <add name="Access-Control-Allow-Headers" value="Content-Type" />
    <add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE, OPTIONS" />
  </customHeaders>
 </httpProtocol>
</system.webServer>
