在使用"get"時(shí)，抓取的頁面最后加上編碼類型，在使用post時(shí)用vbscript解決了編碼問題，具體實(shí)現(xiàn)如下，有類似情況的朋友可以參考下哈

在使用"get"時(shí)，抓取的頁面最后加上編碼類型

 
<% 
服務(wù)器端：servletactioncontext.getresponse().setcharacterencoding("utf-8"); 
客戶端 網(wǎng)頁特效p/jsp.html target=_blank >jsp教程： <%@ page language="java" contenttype="text/html; charset=utf-8" pageencoding="utf-8"%> 
response.expires = -9999 
response.addheader "pragma","no-cache" 
response.addheader "cache-ctrol","no-cache" 
response.addheader "content-type","text/html; charset=gb2312"'這是重點(diǎn)，否則會出現(xiàn)亂碼 
response.write "中文漢字"%> 

2、在使用post時(shí)用vbscript解決了編碼問題：
源碼如下：

復(fù)制代碼代碼如下:

 
<script language="vbscript"> 
function urlencoding(vstrin) 
strreturn = "" 
for i = 1 to len(vstrin) 
thischr = mid(vstrin,i,1) 
if abs(asc(thischr)) < &hff then 
strreturn = strreturn & thischr 
else 
innercode = asc(thischr) 
if innercode < 0 then 
innercode = innercode + &h10000 
end if 
hight8 = (innercode and &hff00) &hff 
low8 = innercode and &hff 
strreturn = strreturn & "%" & hex(hight8) & "%" & hex(low8) 
end if 
next 
urlencoding = strreturn 
end function 
function bytes2bstr(vin) 
strreturn = "" 
for i = 1 to lenb(vin) 
thischarcode = ascb(midb(vin,i,1)) 
if thischarcode < &h80 then 
strreturn = strreturn & chr(thischarcode) 
else 
nextcharcode = ascb(midb(vin,i+1,1)) 
strreturn = strreturn & chr(clng(thischarcode) * &h100 + cint(nextcharcode)) 
i = i + 1 
end if 
next 
bytes2bstr = strreturn 
end function 
</script> 

下面是使用vbscript函數(shù)：

復(fù)制代碼代碼如下:

 
<script language=網(wǎng)頁特效> 
/** 
* 初始化一個(gè)xmlhttp對象 
*/ 
function initajax() 
{ 
var ajax=false; 
try { 
ajax = new activexobject("msxml2.xmlhttp"); 
} catch (e) { 
try { 
ajax = new activexobject("microsoft.xmlhttp"); 
} catch (e) { 
ajax = false; 
} 
} 
if (!ajax && typeof xmlhttprequest!='undefined') { 
ajax = new xmlhttprequest(); 
} 
return ajax; 
} 
function saveuserinfo() 
{ 
var msg = document.getelementbyid("msg"); 
var f = document.user_info; 
var username = f.user_name.value; 
var userage = f.user_age.value; 
var usersex = f.user_sex.value; 
var url = "save.asp教程"; 
var poststr = urlencoding("user_name="+ username +"&user_age="+ userage +"&user_sex="+ usersex);//post時(shí)采用編碼傳遞 
var ajax = initajax(); 
ajax.open("post", url, true); 
ajax.setrequestheader("content-type","application/x-www-form-urlencoded"); 
ajax.send(poststr); 
ajax.onreadystatechange = function() { 
if (ajax.readystate == 4 && ajax.status == 200) { 
msg.innerhtml = bytes2bstr(ajax.responsebody); //獲取時(shí)解碼 
} 
} 
} 
</script> 
<form name="user_info"> 
姓名：<textarea name="user_name" /></textarea><br /> 
年齡：<input type="text" name="user_age" /><br /> 
性別：<input type="text" name="user_sex" /><br /> 
<input type="button" value="提交表單" onclick="saveuserinfo()"> 
</form> 
<div id="msg"></div> 
成功
