HttpWebResponse的编码问题

本文关键字：问题 编码 HttpWebResponse | 更新日期: 2023-09-27 18:16:30

我有从http web响应收到的字符编码问题，我收到?而不是é。

我将编码设置为根据网页的Content-Type即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();

你能告诉我有什么问题吗?

HttpWebResponse的编码问题

在提出请求之前尝试添加以下内容:

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

顺便说一句，如果你想尝试我提出的解决方案，你应该保持你的StreamReader与ISO-8859-1(而不是UTF8)。好运！

你试过将它设置为UTF-8吗?此外，你发送了一个推荐人，我认为你试图设置UserAgent。下面的代码与您的代码相同，但是没有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();
}
