1.Asp 对象与内置组件 1.1 Response resPonse.write "html语句" response.redirect "url" response.writeBinary Variable (图像资料) response.end response.clear response.Flush response.AppenTLog "Information" ->iis login file response.buffer=true/false -> 马上解释马上显示 response.ContentType="text/html" "image/gif" response.CharSet "gb2312" response.expirse=n 分 (0) response.ExpireAbsolute=#9，2000 8:30:30# response.status="403 Forbidden" ResPonse.Cookies(cookie)[key]|(.attribute)=value .cookies() 的属性.Domain .expires 到期时间 .HasKeys .Path response.cookies("University")="TsingHua" response.cookies("university").expires="January,1,2001" response.cookies("university").("TsingHua")="January" 一个可有多值 1.2 Request Request.form("ID") request.querystring("ID") 1.3 Server变量和方法 ServerVariables For each name in Request.ServerVariables response.write("<br>"&name&"="&Request.serverVariables(name) next Server.method server.createobject() server.mappath() server.HtmEncode("<html>") 不会被解释 server.urlEncode("url") 1.4 Session session.collection|Property|method <%@ EnableSessionstate=False%> session.SessionID (会话标识) session.Timeout (分钟为单位) session.Abandon (破坏释放) for i=1 to Session.Contents.Count Response.write("<br>"&Session.contents(i)) next 1.5 Application Application("aa")="aa" set Application("My")=server.createobject("MYcomponent") global.asa <script language=Vbscript runat=server> sub Application_onStart Applicaiton.lock Application("All")=0 Application("OnLine")=0 Application.unlock end sub Sub session_Onstart Application.lock Application("Online")= Application("ONline")+1 Application("all")= Application("all")+1 Application.unlock end Sub sub session_onend Application.lock Application("Online")=Application("Online")-1 end sub Sub Application_Onend end sub </script> 1.6 内置组件 略 2.使用浏览器的能力 [browscap.ini 文件最新] <%set Mybrow=server.createobject("mswc.browserType") aa=mybrow.browser %> browser: 浏览器类型 version: 版本号 majorver: 主版本 miorver: 辅版本 frames: 支持分屏 tables: 支持表格 cookies: 支持cookies backgroundsounds:支持bgsound vbscript: 支持否 javascripts: 支持否 javaapplets: 支持否 activexcontrols: 支持否 beta: 是否是测试版 platform: os win16: 16(win31) 32(win95 winnT) 3.文件存取 File Access: 1 FilesystemObject 文件系统基本方法 2 textstream 读写文本文件 3 file 处理单个文件 4 folder 处理文件夹 5 drive 磁盘驱动器与网络共享 File Access Component: 1 Files 文件夹中一系列文件 2 Folder 3 Drive 文件读写 <% set Fobject=server.createobject("scripting.FilesystemObject") set Tfile=Fobject.CreateTextFile("aa.txt") """"" set Tfile=Fobject.opentextfile """"" while not Tfile.atEndofStream """"" response.write (tFIle.readline) """"" wend Tfile.writeline("hellp") Tfile.close %> CreateTextFile(filename,[Overwrite(true/False)[,unicode]]) Opentextfile(filename[,Mode] [,Create] [,Format]) mode:1 ForReading , 8 ForAppending Create 文件不存在是否创建 true/false format -2 默认， -1 unicode , 0 ASCII textstream的属性 和 方法 atendofLine Read(N) atendofstream ReadLine() column ReadAll line Skip(n) Close 文件的处理 set Fileobject=server.createobject(scripting.FileSystemOjbect) set Tfile=Fileobject.opentextfile("aa.txt") 或者 set Tfile=FileObject.getFile("aa.txt") FilesystemObject 方法 File 方法 File 属性 Fileobject.copyFile "aa.txt" "bb.txt" Tfile.copy "bb.txt" attributes 0 normal ,1 read-only Fileobject.MoveFile "aa.txt" "bb.txt" Tfile.move "bb.txt" 2 hidden ,4 system 8 volume, Fileobject.deleteFile "aa.txt" Tfile.delete 16 directory ,32 archive 64 alias ,128 compressed dateCreated 创建日期 DateLastAccessed 最后访问日期 DateLastModified 最后修改日期 Drive 驱动器 name 文件名 ParentFolder 所在文件夹 path 全路径 size 文件字节数 type 文件类型 FileSystemObject 的方法 set FileObject=server.createobject(scripting.Filesystemobject) FileObjet.FileExists(fileName) FileObjet.GetFile(fileName) Myfileobject.DirveExists("c:") Myfileobject.GetDrive("C:") Myfileobject.getDriveName(path) Fileobject.CopyFolder "c:\aa" "d:\bb" Fileobject.DeleteFolder "c:\aa" Fileobject.FolderExists ("c:\aa") Fileobject.GetFolder("c:\") Fileobject.MoveFolder("c:\") 4.驱动器的操作与文件夹的操作 <%set myfileobject=server.createobject("scripting filesystemObject") for each thing in myfileobject.driver %> thing.driverletter thing.totalsize thing.availablespace next 'FilesystemObject 方法 Myfileobject.DirveExists("c:") Myfileobject.GetDrive("C:") Myfileobject.getDriveName(path) 'driver 方法 set Dir=FileSystemobject.getDrive("C:") dir.AvailableSpace() '可用空间 dir.driverletter 'drive name dir.DriveType 'cd-rom removeable drive dir.serialNumber 'serialNumber dir.totalsize dir.shareName dir.VolumnName 'FilesystemObject 方法 Fileobject.CopyFolder "c:\aa" "d:\bb" Fileobject.DeleteFolder "c:\aa" Fileobject.FolderExists ("c:\aa") Fileobject.GetFolder("c:\") Fileobject.MoveFolder("c:\") 'Folder 方法 set Fol=FileSystemObject.getFolder("c:\MyFile") for each thing in Fol.Files response.write ("<p>"&thing) ' next Fol.copyFolder "d:\bb" [,overwrite] Fol.DeleteFolder Fol.Files Fol.name Fol.moveFolder "c:\aa" 5.邮件发送 [ smtp service ] asp 发送email sub sendMail(fromwho,towho,subject,body) dim mymail set mymail=server.createobject("CDONTS.Newmail") Mymail.From=FromWho Mymail.To=Towho Mymail.Subject=Subject MyMail.Body=body 'Mymail.AttachFile thispage "source" Mymail.cc="d@d.com" '抄送 Mymail.bcc="a@a.com;b@b.com;c@c.com" '密送 Mymail.Sendset set Mymail=NOthing end sub 'FromWho=trim(reauest.form("fromWho")) '... '... 'If towho<>"" then ' SendMail fromwho,towho,subject,body 'end If 6.Ado 主要对象 1 Connection: 2 Command 3 Recordset 4 Error 5 Parameter 6 Property 7 Field SET CONN=SERVER.CREATEOBJECT("ADODB.CONNECTION") 'SET RS=SERVER.CREATEOBJECT("ADODB.RECORDSET") 'SET COMM=SERVER.CREATEOBJECT("ADODB.COMMAND") CONN.OPEN "DSN=HELLO" SET RS=CONN.EXECUTE(SQLLANGUAGE) ' n,n | 1,3 WHILE RS.EOF RS.MOVENEXT RS.MOVEFIRST RS.MOVELAST RS.MOVEPREVIOUS RS.MOVE NUMBER WEND 'RS.move,RS.BOF RS.EOF 'RS.RecordCount RS.PageCount RS.PageSize RS.MaxRecords 'RS.AbsolutePage .RS.CursorLocation=3 RS.AbsolutePosition [位置顺序号] 要配合使用 'rs("fieldname") rs(Number) rs.Fields("fieldname") rs.Fields(Number) 'Rs.Fields.Item("fieldname") Rs.Fields.item(Number) 关于Connection 与 Command Set Conn=Server.CreateObject("Adodb.Connection") Set MyCommand=server.createObject("Adodb.Command") Conn.open "DSN=Hello" Set Mycommand.activeConnection=Conn Mycommand.CommandType=adCMDText Mycommand.CommandText="select * from tablename" set Rs=Mycommand.Execute() Rs.close conn.close 关于 RecordSet 与 Command Set Conn=Server.CreateObject("Adodb.Connection") Set MyCommand=server.createObject("Adodb.Command") SET RS=SERVER.CREATEOBJECT("ADODB.RECORDSET") Conn.open "DSN=Hello" Set Mycommand.activeConnection=Conn Mycommand.CommandType=adCMDText Mycommand.CommandText="select * from tablename" Rs.open Mycommand,adOpenStatic,adLockOptimstic Rs.close conn.close COMMAND 带参数存储过程 略 不用DSN访问数据源 Connection to Access: " Driver={Microsoft Access Driver (*.mdb)} ;DBQ="& server.mappath("aa.mdb")&"uid=;pwd=;" Connection to Vfp: DBC DBF Connection to SQL: " Driver={Sql Server};Server=carl2; DataBase=pubs; uid=sa;pwd=;" Connection to ORCale: " Driver={Microsoft ODBC for Orcale};server=OrcaleServer.world; uid=demo;pwd=demo;" 该文章在 2013/11/28 11:43:01 编辑过 |
