Answer 1

如果想了解上传的过程可以参考RFC1867文档.然后自己写.

基本分析:
InputStream InData=null;
int iSize,iLength;
iLength=request.getContentLength();
byte[] Buffer=new byte[iLength];
byte[] Byte_File;
if(iLength>0)
{
InData=request.getInputStream();
String ContentType=request.getContentType();
iSize=InData.read(Buffer);
if(iSize!=-1)
{
//数据处理开始
String FileData=new String(Buffer);

//正则字串:"name=\"";
//正则字串:"filename=\"";

String strSplit=ContentType.substring(ContentType.lastIndexOf("=")+1,ContentType.length());
String strSub[]=FileData.split(strSplit); String strElement;
int iBegin,iEnd;
iBegin=0;iEnd=0;
String FieldName,FieldValue;
int bTrue;
bTrue=0;
int iPos;
iPos=0;
int iLocation;
iLocation=0;
for(int iIndex=0;iIndex<strSub.length;iIndex++)
{
strElement=strSub[iIndex];
iBegin=strElement.indexOf("name=\"",0);
if(iBegin!=-1)
{
iEnd=strElement.indexOf("\"",iBegin+6);
FieldName=strElement.substring(iBegin+6,iEnd);
iBegin=strElement.indexOf("filename=\"",0);
if(iBegin!=-1)
{
bTrue=1;
}
//
iEnd=strElement.indexOf("\r\n\r\n",0);
if(bTrue==1)
{
iLocation=0;
iPos=FileData.indexOf("filename=\"",iPos);
iPos=FileData.indexOf("\n",iPos)+1;
iPos=FileData.indexOf("\n",iPos)+1;
iPos=FileData.indexOf("\n",iPos)+1;
iLocation=FileData.indexOf(strSplit,iPos)-4;
FieldValue=FileData.substring(iPos,iLocation);
byte[] Byte_File_=FieldValue.getBytes();
Byte_File=new byte[Byte_File_.length];
for(int kIndex=0;kIndex<Byte_File_.length;kIndex++)
{
Byte_File[kIndex]=Buffer[iPos+0+kIndex];
//0:Excel
//0:Word
//
}
session.putValue(FieldName,Byte_File);
}
else
{
FieldValue=strElement.substring(iEnd+4);
session.putValue(FieldName,FieldValue.substring(0,FieldValue.indexOf("\n")-1));
}
bTrue=0;
}
}
//数据处理结束
                  }
         }
