如何在特定文件 web.config 上设置访问控制允许来源 [英] How to set access control allow origin on particular file web.config

问题描述

如果这是一个动态响应，我会简单地做 Response.Headers.Add("Access-Control-Allow-Origin", "*"); 但我有一个静态文件我'想允许跨域访问.

If this were a dynamic response, I'd simply do Response.Headers.Add("Access-Control-Allow-Origin", "*"); but I have a static file I'd like to allow cross domain access to.

有没有办法仅使用 web.config 将此标头分配给特定文件?说它只是example.com/flat.json

Is there a way to assign this header to a particular file just using web.config? Say it's just example.com/flat.json

我想我可以将文件路由到动态页面，但这有点傻.

I guess I could route the file to dynamic page, but that would be a bit silly.

推荐答案

这应该可行

<location path="Sample.txt">
    <system.webServer>
      <httpProtocol>
        <customHeaders>
          <add name="Access-Control-Allow-Origin" value="*" />
        </customHeaders>
      </httpProtocol>
    </system.webServer>
  </location>
