正如这篇文章所暗示的 chrome 中的错误:Access-Control-Allow-Headers 不允许内容类型 只需将附加标头添加到您的 web.config 中即可所以……

As hinted at by this post Error in chrome: Content-Type is not allowed by Access-Control-Allow-Headers just add the additional header to your web.config like so...

<httpProtocol>
  <customHeaders>
    <add name="Access-Control-Allow-Origin" value="*" />
    <add name="Access-Control-Allow-Headers" value="Origin, X-Requested-With, Content-Type, Accept" />
  </customHeaders>
</httpProtocol>
