HttpWebRequest.Timeout在发起请求开始,如果未从远程请求的URL得到任何数据的情况下,超过Timeout后,触发超时异常 HttpWebRequest.ReadWriteTimeout 在发起请求后,从远程请求的URL中得到部分信息,然后等待后续数据时,在此期间,超过ReadWriteTimeout时,触发超时异常 如果仅设置了Timeout,那么如果在得到一部分数据时,超过Timeout时不会触发异常…

公司[1]一牛人看我的代码,说我设置的timeout有误,还应该设置ReadWriteTimeout.本人很不服,于是上网查看了相关说明. HttpWebRequest httpWebRequest = WebRequest.CreateHttp("http://www.kangry.net"); httpWebRequest.ReadWriteTimeout = ; httpWebRequest.Timeout = ; MSDN对ReadWriteTimeout的说明如下: 在写入由…

最近抓网页时报错: 要么返回 The remote server returned an error: (442)要么返回: 非法访问,您的行为已被WAF系统记录! 想了想,就当是人家加了抓网页的东西,于是改了一下方法 加上Request.Header 之类的东西就行了. 具体加什么,咱们可以先用 fildder 抓一下包就可以了如:   GET http://www.baidu.com/ HTTP/1.1Host: www.baidu.comConnection: keep-aliveUpgr…

[问题] 用C#模拟网页登陆,其中去请求几个页面,会发起对应的http的请求request,其中keepAlive设置为true,提交请求后,然后会有对应的response: resp = (HttpWebResponse)req.GetResponse(); 之前的多次调试,一直都是可以正常获得对应的response,然后读取html页面的. 但是后来几次的调试,在没有改变代码的前提下,结果GetResponse却始终会超时死掉. [解决过程] 1.默认request的timeout是1000…

WebApi现在越来越流行,下面给出利用HttpWebRequest访问WebApi的工具方法: 1.利用基准URL和参数字典生成完整URL /// <summary> /// 生成URL字符串 /// </summary> /// <param name="baseUrl">基准URL</param> /// <param name="dictParam">参数字典</param> /// &…

为了提高httpwebrequest的执行效率,查到了一些如下设置 request.ServicePoint.Expect100Continue = false; request.ServicePoint.UseNagleAlgorithm = false; request.ServicePoint.ConnectionLimit = 65500; request.AllowWriteStreamBuffering = false; request.Proxy = null; 然后就看到了如下相…
