默认情况下会拦截**所有**的xhr请求，添加 `ws8` 头部用于追踪。 添加头部后的请求就不再是[简单请求](https://developer.mozilla.org/zh-CN/docs/Web/HTTP/CORS#%E7%AE%80%E5%8D%95%E8%AF%B7%E6%B1%82)，浏览器会发起预请求。 ``` Access-Control-Request-Headers: ws8 ``` 需要服务器在响应头都添加一下头部 ``` Access-Control-Allow-Headers: ws8 ``` 对于不受控制的第三方服务，这样很不好做。建议添加`origin`白名单，实现对白名单内服务`xhr`的请求拦截。 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
