HttpWebResponse 的编码问题

发布于 2024-12-19 03:49:11 字数 1020 浏览 0 评论 0原文

我从 http Web 响应接收的字符编码有问题，我收到 ? 而不是 é。

我根据网页的 Content-Type 设置编码，即 text/javascript;字符集=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();

你能告诉我它出了什么问题吗？

I have problems with characters encoding received from http web response, I receive ? instead é.

I set the encoding to according Content-Type of web page that's text/javascript; charset=ISO-8859;

My code is:

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();

Can you tell me what is wrong with it?

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，如果您想尝试我建议的解决方案，您应该将 StreamReader 保留为 ISO-8859-1（而不是 UTF8）。祝你好运！

Try adding the following before you make your request:

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

Btw, you should keep your StreamReader with ISO-8859-1 (instead of UTF8) if you want to try my proposed solution. Good luck!

您是否尝试过将其设置为UTF-8？
此外，您还发送了一个引荐来源网址，我认为您尝试设置 UserAgent。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();
}

Have you tried setting it at UTF-8?
Further more you send a referrer which I think you tried to set the UserAgent. The code below is the same as yours, but then does not go over the byte array and sets the useragent and utf8 encoding.

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();
}
