response.getOutputStream().write();问题

Question

response.getOutputStream().write(new String(content,0,字节长度);

Answer 1

上面错了改为response.getOutputStream().write(content,0,字节长度); 试试看。

Answer 2

PrinterWriter pw = response.getOutputStream();
然后用pw.write()来写,
如果还不行把你的content里的东西转一下码,之后写进去

Answer 3

public void writeToHttpServletResponseWithDownloadFile(javax.servlet.http.
      HttpServletResponse response) throws java.io.IOException
  {
    response.setContentType(this.getContentType());
    response.addHeader("Accept-Ranges", "bytes");
    response.addHeader("Accept-Length", String.valueOf(this.content.length));
    response.addHeader("Content-Disposition",
                       "attachment; filename=\"" + this.name + "\"");
//    response.setContentType("text/html;charset=GBK");
    System.out.println("content:"+new String(content,"GBK")+"  content.length:"+content.length);
    response.getOutputStream().write(this.content,0,content.length);
    response.getOutputStream().flush();
    response.getOutputStream().close();
  }
content是文件内容,是对的
文件名是this.name，传过去是乱码

Answer 4

PrinterWriter pw=response.getOutputStream();
这要报错的嘛
