restSharp 使用中关于Timeout Exception的坑

必须设置 ThrowOnAnyError = true; 不然设置TimeOut也不会报异常,

            client.Timeout = iTimeOut * 1000;
            client.ThrowOnAnyError = true;  //设置不然不会报异常

而且很多时候并不是显示TimeoutException, 而是显示 WebException , 所以一般如下设置try/catch就可以保证大部分情况下能正常工作, 而不是一直挂在那里不返回也不报错. 

                    try
                    {
                        IRestResponse response = client.Execute(request);
                        if (response.StatusCode == HttpStatusCode.OK)
                        {
                            if (response.Content.Length > iMinHtmlLen && response.Content.Contains(CheckStr))
                            {
                                long elMs = sw.ElapsedMilliseconds;
                                item.CheckLastDelayMs = elMs;
                            }
                            else
                            { item.CheckLastErrMsg = ($"返回长度小于{iMinHtmlLen}或搜索不到 {CheckStr} "); }
                        }
                        else
                        {
                            string retContent = (response.Content.Length < 200) ? response.Content : response.Content.Substring(0,200) ;
                            item.CheckLastErrMsg = ($"返回码!=OK {response.StatusCode} 前200字节: {retContent}"); 
                        }
                    }
                    catch (TimeoutException)
                    { item.CheckLastErrMsg = ($"TimeoutException"); }
                    catch (System.Net.Http.HttpRequestException)
                    { item.CheckLastErrMsg = ($"HttpRequestException"); }
                    catch (WebException)
                    { item.CheckLastErrMsg = ($"WebException"); }
