First, let's analyze why Chinese characters are garbled. The reason is simple: when XMLHTTP gets response, it is assumed that response is utf8 encoded. It treats HTML with gb2312 Encoding As utf8 format, so Chinese garbled characters appear.
So, is there no client solution besides the ASP server-side scripting technology? The answer is: yes!
I used the VBScript client script to successfully implement the non-use of ASP, which solved the problem of Chinese garbled characters when XMLHTTP captured HTML pages.
Why does VBScript be used instead of common jscripts? The responsebody of XMLHTTP returns an unsigned bytes array. VBScript provides many functions for operating strings and formatting data, as well as methods for accessing secure arrays. These functions or methods do not exist in JScript. Here we need to use the built-in functions of VBScript: midb, ASCB, and lenb to access the responsebody.
I am not emphasizing that VBScript is better than JScript, but that both of them have their own characteristics. I wrote an article on csdn for the first time. Thank you for your support. There are two purposes for writing this article: 1. Exercise yourself; 2. When you encounter problems, learn to analyze the problems and be specific.
I gave the code test.htm, which includes two types of applications: getting your own code and getting other webpage code. The specific script is as follows:
<! Doctype HTML public "-// W3C // dtd html 4.0 transitional // en">
<! -- Author: Kobayashi, sulins@tom.com -->
<HTML>
<Head>
<Meta http-equiv = "Content-Type" content = "text/html; charset = gb2312">
</Head>
<Script language = VBScript>
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
Function viewsource1 ()
Dim XMLHTTP
Set XMLHTTP = Createobject ("Microsoft. XMLHTTP ")
XMLHTTP. Open "get", document. Location. href, false
XMLHTTP. setRequestHeader "Content-Type", "text/XML"
XMLHTTP. Send
Dim html
Html = bytes2bstr (XMLHTTP. responsebody)
Msgbox html
End Function
Function viewsource2 ()
Dim XMLHTTP
Set XMLHTTP = Createobject ("Microsoft. XMLHTTP ")
XMLHTTP. Open "get", "http://www.google.com", false
XMLHTTP. setRequestHeader "Content-Type", "text/XML"
XMLHTTP. Send
Dim html
Html = bytes2bstr (XMLHTTP. responsebody)
Msgbox html
End Function
