推荐答案

在这里你去 - 注意，您必须DECOM preSS gzip的EN codeD-结果你回来的as每 mleroy ：

Here you go - note you have to decompress the gzip encoded-result you get back as per mleroy:

private static async Task<string> GetResponse(string url)
{
    var httpClient = new HttpClient();

    httpClient.DefaultRequestHeaders.TryAddWithoutValidation("Accept", "text/html,application/xhtml+xml,application/xml");
    httpClient.DefaultRequestHeaders.TryAddWithoutValidation("Accept-Encoding", "gzip, deflate");
    httpClient.DefaultRequestHeaders.TryAddWithoutValidation("User-Agent", "Mozilla/5.0 (Windows NT 6.2; WOW64; rv:19.0) Gecko/20100101 Firefox/19.0");
    httpClient.DefaultRequestHeaders.TryAddWithoutValidation("Accept-Charset", "ISO-8859-1");

    var response = await httpClient.GetAsync(new Uri(url));

    response.EnsureSuccessStatusCode();
    using (var responseStream = await response.Content.ReadAsStreamAsync())
    using (var decompressedStream = new GZipStream(responseStream, CompressionMode.Decompress))
    using (var streamReader = new StreamReader(decompressedStream))
    {
        return streamReader.ReadToEnd();
    }
}

通话等类：

var response = await GetResponse("http://www.livescore.com/"); // or var response = GetResponse("http://www.livescore.com/").Result;
