二、ASPUpload组件
1.简介
AspUpload is a COM+ component which enables an ASP application to capture, save and process files uploaded to the web server with a browser. The files are selected for uploading via an HTML POST form using the <INPUT TYPE=FILE> tag.
With AspUpload, you can add file upload functionality to your Web application in as little as 2 lines of ASP script. In addition to uploading, AspUpload offers a wide range of file management functions, including secure downloading, saving files in the database, permission and attribute management, image size extraction, file encryption, etc.
2.组件使用举例
两个文件Form1.asp和UploadScript1.asp
Form1.asp enables a user to select up to three files for uploading to the server.
|
<HTML>
<BODY BGCOLOR="#FFFFFF">
<h3>Simple Upload</h3>
<FORM METHOD="POST" ENCTYPE="multipart/form-data" ACTION="UploadScript1.asp">
<INPUT TYPE="FILE" SIZE="40" NAME="FILE1"><BR>
<INPUT TYPE="FILE" SIZE="40" NAME="FILE2"><BR>
<INPUT TYPE="FILE" SIZE="40" NAME="FILE3"><BR>
<INPUT TYPE=SUBMIT VALUE="Upload!">
</FORM>
</BODY>
</HTML>
|
UploadScript1.asp includes the upload script.
|
<HTML>
<BODY>
<%
Set Upload = Server.CreateObject("Persits.Upload")
Count = Upload.Save("c:\upload")
Response.Write Count & " file(s) uploaded to c:\upload"
%>
</BODY>
</HTML>
|
UploadScript1.asp代码解释
The first line of the ASP script simply creates an instance of the AspUpload object. The second line calls the Save method of the component which actually performs the upload: it parses the information POSTed by the browser, figures out how many files are being uploaded, and saves them in a specified local directory on the server under their original names.
The Save method returns the number of files successfully uploaded. In case of an error this method will throw an exception.
