用JSP分析multipart/form-data基于表单的文件上传(1) <%
int iTotalByte,iTotalRead,iReadByte;
iTotalByte=request.getContentLength();
iTotalRead=0;
iReadByte=0;
byte[] Buffer=new byte[iTotalByte];
if(iTotalByte>0)
{
for(;iTotalRead<iTotalByte;iTotalRead+=iReadByte)
{
try
{
iReadByte=request.getInputStream().read(Buffer,iTotalRead,iTotalByte-iTotalRead);
}
catch(Exception e)
{
e.printStackTrace();
}
}
String strContentType=request.getContentType();
//数据处理开始
String strBuffer=new String(Buffer);
%><!--<br>表单数据:<br>strBuffer<br>--><%
String strBoundary="--"+strContentType.substring(strContentType.lastIndexOf("=")+1,strContentType.length());
String strArray[]=strBuffer.split(strBoundary);
String strSubString;
int iBegin,iEnd;
iBegin=0;iEnd=0;
String strFieldName="";
String strFieldValue="";
String strFilePath="";
String strFileName="";
String strFileType="";
boolean bTrue;
bTrue=false;
int iLocation=0;
for(int iIndex=1;iIndex<strArray.length-1;iIndex++)

if(iBegin!=-1)
{
strFieldName="";strFieldValue="";

iEnd=strSubString.indexOf("\"",iBegin+6);
strFieldName=strSubString.substring(iBegin+6,iEnd);
