分享HttpWebRequest获取网页,中文字符为何变成乱码?
本程序在Microsoft Visual Web Developer 2005 Bata2中文版下调试:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim mr As HttpWebRequest
Dim mt As HttpWebResponse
Dim sr As StreamReader
Dim li As String
mr = CType(WebRequest.Create("http://www.163.com/"), HttpWebRequest)
mt = CType(mr.GetResponse(), HttpWebResponse)
sr = New StreamReader(mt.GetResponseStream())
li = sr.ReadLine()
Do While Not li Is Nothing
li = HttpUtility.HtmlEncode(li)
If li.Length <> 0 Then
Response.Write(li & "<BR>")
End If
li = sr.ReadLine()
Loop
End Sub
得到如下页面:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>????</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />

在new StreamReader的时候指定编码。如果页面的编码方式是中文则指定GB2312，如果是UTF-8则指定UTF-8。
比如(C#)：
StreamReader sr= new StreamReader (tm.GetResponseStream(), Encoding.GetEncoding("GB2312") );
比如(C#)：
StreamReader sr= new StreamReader (tm.GetResponseStream(), Encoding.GetEncoding("GB2312") );
