我们如何在服务器上传所有类型的文件？

Question

       <%@ page import="java.io.*" %>
<%

String contentType = request.getContentType（）;

if（（contentType！= null）＆amp;＆amp;（contentType.indexOf（“multipart / form-data”）＆gt; = 0））{     DataInputStream in = new DataInputStream（request.getInputStream（））;

int formDataLength = request.getContentLength();
byte dataBytes[] = new byte[formDataLength];
int byteRead = 0;
int totalBytesRead = 0;

while (totalBytesRead < formDataLength) 
{
    byteRead = in.read(dataBytes, totalBytesRead, formDataLength);
    totalBytesRead += byteRead;
}

String file = new String(dataBytes);

String saveFile = file.substring(file.indexOf("filename=\"") + 10);
saveFile = saveFile.substring(0, saveFile.indexOf("\n"));
saveFile = saveFile.substring(saveFile.lastIndexOf("\\")+1,saveFile.indexOf("\""));
int lastIndex = contentType.lastIndexOf("=");
String boundary = contentType.substring(lastIndex +1,contentType.length());
int pos;

pos = file.indexOf("filename=\"");
pos = file.indexOf("\n", pos) + 1;
pos = file.indexOf("\n", pos) + 1;
pos = file.indexOf("\n", pos) + 1;
int boundaryLocation = file.indexOf(boundary, pos) - 4;
int startPos = ((file.substring(0, pos)).getBytes()).length;
int endPos = ((file.substring(0, boundaryLocation))
.getBytes()).length;
saveFile="http://hpws1/shared_mxd/pdf/" + saveFile;

FileOutputStream fileOut = new FileOutputStream(saveFile);
fileOut.write(dataBytes, startPos, (endPos - startPos));
fileOut.flush();
fileOut.close();

您正在使用该scriptlet做什么不再可接受。您可以尝试使用servlet and form代替上传。
