When you use "get", the page that you crawl finally adds the encoding type
Copy Code code as follows:
<%
Server side: Servletactioncontext.getresponse (). setcharacterencoding ("Utf-8");
Client page Special effects p/jsp.html target=_blank >jsp Tutorial: <%@ 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 "' This is the key, otherwise there will be garbled
Response.Write "Chinese Characters"%>
2. Use VBScript to solve the coding problem when using post:
The source code is as follows:
Copy Code code as follows:
<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>
The following is the use of VBScript functions:
Copy Code code as follows:
<script language= Web page Special effects >
/**
* Initialization of a XMLHTTP object
*/
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 tutorial";
var poststr = urlencoding ("user_name=" + username + "&user_age=" + userage + "&user_sex=" + usersex);
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); decoding when getting
}
}
}
</script>
<form name= "User_info" >
Name: <textarea name= "user_name"/></textarea><br/>
Age: <input type= "text" name= "User_age"/><br/>
Sex: <input type= "text" name= "User_sex"/><br/>
<input type= "button" value= "Submitting form" onclick= "Saveuserinfo ()" >
</form>
<div id= "MSG" ></div>
Success
