ASP实例 一个简易的ASP无组件上传类
|
简单的ASP无组件上传类，发出来让大家看看。可以做做实验！ 以下为引用的内容： <%@ language="javascript"%> <% var self = Request.serverVariables("SCRIPT_NAME"); if (Request.serverVariables("REQUEST_METHOD")=="POST") { var oo = new uploadFile(); oo.path = "myFile"; //存放路径,为空表示当前路径,默认为uploadFile oo.named = "file"; //命名方式,date表示用日期来命名,file表示用文件名本身,默认为file oo.ext = "all"; //允许上传的扩展名,all表示都允许,默认为all oo.over = true; //当存在相同文件名时是否覆盖,默认为false oo.size = 1*1024*1024; //最大字节数限制,默认为1G oo.upload(); Response.write('<script type="text/javascript">location.replace("' self '")</script>'); } //ASP无组件上传类 function uploadFile() { var bLen = Request.totalBytes; var bText = Request.binaryRead(bLen); var oo = Server.createObject("ADODB.Stream"); oo.mode = 3; this.path = "uploadFile"; this.named = "file"; this.ext = "all"; this.over = false; this.size = 1*1024*1024*1024; //1GB //文件上传 this.upload = function () { var o = this.getInfo(); if (o.size>this.size) { alert("文件过大,不能上传!"); return; } var f = this.getFileName(); var ext = f.replace(/^. /./,""); if (this.ext!="all"&&!new RegExp(this.ext.replace(/,/g,"|"),"ig").test(ext)) { alert("目前暂不支持扩展名为 " ext " 的文件上传!"); return; } if (this.named=="date") { f = new Date().toLocaleString().replace(//D/g,"") "." ext; } oo.open(); oo.type = 1; oo.write(o.bin); this.path = this.path.replace(/[^////]$/,"$&/"); var fso = Server.createObject("Scripting.FileSystemObject"); if(this.path!=""&&!fso.folderExists(Server.mapPath(this.path))) { fso.createFolder(Server.mapPath(this.path)); } try { oo.saveToFile(Server.mapPath(this.path f),this.over?2:1); alert("上传成功!"); } catch(e) { alert("对不起,此文件已存在！"); } oo.close(); delete(oo); } //获取二进制和文件字节数 this.getInfo = function () { oo.open(); oo.type=1; oo.write(bText); oo.position = 0; oo.type=2; oo.charset="unicode"; var gbCode=escape(oo.readText()).replace(/%u(..)(..)/g,"%$2%$1"); var sPos=gbCode.indexOf("") 12; var sLength=bLen-(gbCode.substring(0,gbCode.indexOf("")).length/3)-sPos/3-6; oo.close(); oo.open(); oo.type = 1; oo.write(bText); oo.position=sPos/3; var bFile=oo.read(sLength); oo.close(); return { bin:bFile, size:sLength }; } //获取文件名 this.getFileName = function () { oo.open(); oo.type = 2; oo.writeText(bText); oo.position = 0; oo.charset = "gb2312"; var fileName = oo.readText().match(/filename=/"(. ?)/"/i)[1].split("//").slice(-1)[0]; oo.close(); return fileName; } function alert(msg) { Response.write('<script type="text/javascript">alert("' msg '");</script>'); } } %> <html> <head> <title>ASP无组件上传类</title> <meta http-equiv="content-Type" content="text/html; charset=gb2312"> </head> <body> <form action="<%=self%>" method="post" enctype="multipart/form-data" onSubmit="return (this.upFile.value!='');"> <input type="file" name="upFile"/> <input type="submit" value="上传文件"/> </form> </body> </html> （编辑：银川站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
