Question

我从http网络回复收到的字符编码有问题，我收到?而不是é。

我将编码设置为Content-Type的网页的text/javascript; charset=ISO-8859;

我的代码是：

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(..);
request.Method = "GET";
request.AllowAutoRedirect = false;
request.Referer = "Mozilla/5.0 (Windows NT 6.1; rv:7.0.1) Gecko/20100101 Firefox/7.0.1";
request.Headers.Add("DNT", "1");
request.Accept = "text/html,application/xhtml+xml,application/xml";

HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream stream = response.GetResponseStream();
StreamReader sr = new StreamReader(stream, Encoding.GetEncoding("iso-8859-1"));

char[] buf = new char[256];
int count;
StringBuilder buffer = new StringBuilder();

while ((count = sr.Read(buf, 0, 256)) > 0)
{
    buffer.Append(buf, 0, count);
}

string responseStr = buffer.ToString();
Console.WriteLine(responseStr);
response.Close();
stream.Close();
sr.Close();

你能告诉我它有什么问题吗？

Answer 1

在提出请求之前，请尝试添加以下内容：

request.Headers.Add(HttpRequestHeader.AcceptCharset, "ISO-8859-1");

顺便说一句，如果您想尝试我提出的解决方案，您应该使用ISO-8859-1（而不是UTF8）保存您的StreamReader。祝你好运！

您是否尝试过以UTF-8设置？您还发送了一个我认为您尝试设置UserAgent的推荐人。下面的代码与您的代码相同，但不会遍历字节数组并设置useragent和utf8编码。

var request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "GET";
request.AllowAutoRedirect = false;
request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; rv:7.0.1) Gecko/20100101 Firefox/7.0.1";
request.Headers.Add("DNT", "1");
request.Accept = "text/html,application/xhtml+xml,application/xml";

using(var response = (HttpWebResponse)request.GetResponse())
using(var stream = response.GetResponseStream())
using (var sr = new StreamReader(stream, Encoding.UTF8))
{
    string responseStr = sr.ReadToEnd();
    Console.WriteLine(responseStr);
    response.Close();
    if (stream != null)
        stream.Close();
    sr.Close();
}
