WebClient.DownloadString 结果与浏览器结果 2 不匹配
WebClient.DownloadString result is not match with Browser result 2
以下代码:
WebClient wc = new WebClient();
wc.Encoding = Encoding.UTF8;
string Url = "http://www.tsetmc.com/tsev2/data/instinfodata.aspx?i=59266699437480384&c=64";
return wc.DownloadString(Url);
代码returns:
�Q�T�MP�J�A|�^D����~���C�"�����l� ��;I&3=j=�iG�H9Ȓ�J�^� �j��T�Q=HH�'Qm�������1�hF�4�*�������{�x�\o?
当我在任何网络浏览器中访问 URL 时,我得到:
12:29:45,A ,3540,3567,3600,3621,3690,3515,140,238204,849582597,1,20140914,122945;;1@2825@3523@3583@1700@1,1@2000@3522@3600@8700@2,1@500@3511@3640@2500@1,;19774,99736,1
有没有办法得到正确的字符串?
另外,我使用这个在线解码器,但我没有得到正确的答案:
Universal Online Decoder
这不是编码问题,我认为它与压缩有关,在本例中为 gzip。阅读Uncompressing gzip response from WebClient。
那应该可以解决您的问题。
public class WC : WebClient
{
protected override WebRequest GetWebRequest(Uri url)
{
var request = base.GetWebRequest(url) as HttpWebRequest;
request.AutomaticDecompression = DecompressionMethods.GZip;
return request;
}
}
用法:
var url = "http://www.tsetmc.com/tsev2/data/instinfodata.aspx?i=59266699437480384&c=64";
var wc = new WC();
wc.Encoding = Encoding.UTF8;
var result = wc.DownloadString(url);
在 Linqpad 中,您可以 运行 以下代码,Webclient 的变体。从图中可以看出,这是由于浏览器自动处理的 Gzip 压缩所致。
async void Main()
{
using (var handler = new HttpClientHandler())
{
handler.AutomaticDecompression = DecompressionMethods.GZip;
using (HttpClient client = new HttpClient(handler))
{
var result = await client.GetStringAsync("http://www.tsetmc.com/tsev2/data/instinfodata.aspx?i=59266699437480384&c=64");
result.Dump();
}
}
}
以下代码:
WebClient wc = new WebClient();
wc.Encoding = Encoding.UTF8;
string Url = "http://www.tsetmc.com/tsev2/data/instinfodata.aspx?i=59266699437480384&c=64";
return wc.DownloadString(Url);
