hi Paul:
First, I'm very thank you for your help. Your code is working nice.But I
have got another problem, follow is very code:
@Path("form-data")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@POST
public void uploadUrlFormData(
@FormParam("file") InputStream file,
@FormParam("file") FormDataContentDisposition cd
) throws IOException {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
int read = 0;
byte[] buf = new byte[4096];
while ((read = file.read(buf)) != -1) {
baos.write(buf, 0, read);
}
byte[] byteArr = baos.toByteArray();
File f = new File("c:/a.rar");
FileOutputStream fos = new FileOutputStream(f);
BufferedOutputStream bof = new BufferedOutputStream(fos);
bof.write(byteArr);
bof.close();
bof.flush();
fos.close();
baos.close();
file.close();
System.out.println("form-data file name: " + new
String(cd.getFileName().getBytes(),"utf-8"));
}
new String(cd.getFileName().getBytes(),"utf-8")
I want get the uploading file name, But this will get a full path, And
another problem is that the chinese char is not deal, I had got a bad
string.
Any help?
