cefsharp设置网页接受语言Accept-Language

1.设置浏览器的请求控制器

 webView.RequestHandler = new RequestHandler(); 

2.新建RequestHandler类继承IRequestHandler接口，实现方法OnBeforeResourceLoad

   /// <summary>
        /// 资源加载之前事件(请求还未进入服务器)
        /// </summary>
        /// <param name="browser"></param>
        /// <param name="requestResponse"></param>
        /// <returns></returns>
        public bool OnBeforeResourceLoad(IWebBrowser browser, IRequestResponse requestResponse)
        {
            IDictionary<string, string> headers = requestResponse.Request.GetHeaders();
            headers.Add("Accept-Language", "zh,zh-cn,zh-tw");
            requestResponse.Request.SetHeaders(headers);        
            return false; 
        }
