Connecting to a database
function Connopen (DATABASECONNECTSTR) {
var conn = Server.CreateObject ("ADODB.") Connection ");
Conn. Open (DATABASECONNECTSTR);
Return conn;
}
Use the ADODB.stream object to read text files in a specified format
function Readfromtextfile (fileurl,charset) {
var str;
var stm = Server.CreateObject ("ADODB.stream");
Stm. Type = 2;
Stm. Mode = 3;
Stm. Charset=charset;
Stm.open;
Stm. LoadFromFile (Server.MapPath (FILEURL));
str = stm. ReadText
Stm.close;
return str;
}
Use the ADODB.stream object to write to a text file in the specified format
function Writetotextfile (fileurl,str,charset) {
var stm = Server.CreateObject ("ADODB.stream");
Stm. Type = 2;
Stm. Mode = 3;
Stm. Charset = Charset;
Stm.open;
Stm. WRITETEXT (STR);
Stm. SaveToFile (Server.MapPath (FILEURL), 2);
Stm.flush;
Stm.close;
}
Use FSO to determine whether a file exists
function Isfileexist (FILEURL) {
var FSO = Server.CreateObject ("Scripting.FileSystemObject")
if (FSO). FileExists (Server.MapPath (FILEURL))) {
return true;
}else{
return false;
}
}
Use FSO to write files
function Catefile (files,fbody) {
var fs = Server.CreateObject ("Scripting.FileSystemObject");
var a = fs. CreateTextFile (Server.MapPath (files));
A.write (Fbody);
A.close ();
}
Get target page source code
function Gethttppage (URL) {
var http= server.createobject ("Microsoft.XMLHTTP");
Http.open ("Get", url,false);
Http.send ();
if (http.readystate!==4) {return false;}
Return (BYTESTOBSTR (http.responsebody, "GB2312"));
}
Coding
function Bytestobstr (body,cset) {
var objstream = Server.CreateObject ("ADODB.stream");
Objstream. Type = 1;
Objstream. Mode = 3;
Objstream. Open ();
Objstream. Write = body;
Objstream. Position = 0;
Objstream. Type = 2;
Objstream. Charset = Cset;
Return (objstream. ReadText);
Objstream. Close ();
}
Get full Connection Address
function Getcompleteurl (sources_url,get_url) {
if (Get_url.indexof ("http://")!=-1) return get_url;
var completeurl= "";
var Sources_url_arr = Sources_url.split ("/");
var Get_url_arr = Get_url.split (".. /");
for (Var i=0;i<sources_url_arr.length-get_url_arr.length;i++) {
Completeurl + = Sources_url_arr[i] + "/";
}
Completeurl + = get_url_arr[get_url_arr.length-1];
return completeurl;
}
