對我的代碼有任何建議。我不知道爲什麼表現不佳。 我的代碼大約需要200毫秒,而瀏覽器僅有50毫秒,如下圖:HttpWebRequest(200ms)比瀏覽器(50ms)慢4倍
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new Uri(url));
request.Proxy = null;
request.Method = "GET";
request.Accept = "image/jpeg, application/x-ms-application, image/gif, application/xaml+xml, image/pjpeg, application/x-ms-xbap, */*";
request.Headers.Add("Accept-Language", "zh-CN");
request.UserAgent = "Mozilla/5.0 (Windows NT 5.2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.154 Safari/537.36";
request.Headers.Add("Accept-Encoding", "gzip, deflate");
request.KeepAlive = true;
request.AllowAutoRedirect = false;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
string str;
Stream st = response .GetResponseStream();
if (response .ContentEncoding.ToLower().Contains("gzip"))
{
st = new GZipStream(st, CompressionMode.Decompress);
}
StreamReader reader = new StreamReader(st);
str = reader.ReadToEnd();
reader.Close();
response.Close();
你確定你的瀏覽器沒有緩存數據嗎? –
來比較兩件事情,它可能是用來顯示它們兩個。 – GameAlchemist
我使用Http分析器v7來獲取數據。在訪問目標網站之前清除瀏覽器緩存。 – user2724902
