tubage408 2007-12-27 05:16:52

我想学学文件上传，现在是用servlet做的，但是解析输入流的时候总是不对，我的页面上除了file外还有几个text，select我同时也想得到他们的值，我不知道有uploadfile包和jspsmartupload包可不可以。于是我直接解析的到的流，但是解析的时候总是出错，所以来这里请高手帮助，希望前辈们给个例子，最后是我用的那种方式，谢谢

对了，我这个是写死向D盘存一个ZIP文件，那么我上传的也是一个ZIP文件，你可以自行修改，

我自己写了一个，但注意，在有些系统上可能不支持中文路径：
如果你想再传其它参数，应该把参数手动拼到URL后面如：form1.action=form1.action+"?arg1="+form1.name.value;
upload.jsp代码：
<%@ page language="java"
pageEncoding="GBK"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Insert title here</title>
</head>
<body>
<form name="form1" action="/upload/UploadServlet" method="POST" ENCTYPE="multipart/form-data">
<input type="file" name="file1"/><br>
复核人:<input name="verify" value="12312312312"/><input name="verify1" value="12312312312"/><br>
<input type="submit"value="上传"/>
</form>
</body>
</html>
UploadServlet 代码：
package servlet;

import java.io.BufferedOutputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.Enumeration;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import save.SaveFile;

public class UploadServlet extends HttpServlet {
private static final String LINE_SEPARATOR ="\r\n";

/**
* Constructor of the object.
*/
public UploadServlet() {
super();
}

/**
* Destruction of the servlet. <br>
*/
public void destroy() {
super.destroy(); // Just puts "destroy" string in log
// Put your code here
}

/**
* The doGet method of the servlet. <br>
*
* This method is called when a form has its tag value method equals to get.
*
* @param request the request send by the client to the server
* @param response the response send by the server to the client
* @throws ServletException if an error occurred
* @throws IOException if an error occurred
*/
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

doPost(request,response);
}

/**
* The doPost method of the servlet. <br>
*
* This method is called when a form has its tag value method equals to post.
*
* @param request the request send by the client to the server
* @param response the response send by the server to the client
* @throws ServletException if an error occurred
* @throws IOException if an error occurred
*/
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String contentType = request.getContentType();
InputStream in1=request.getInputStream();
int offset = -1;
StringBuffer sb=new StringBuffer();
BufferedOutputStream bos=new BufferedOutputStream(new FileOutputStream("D:\\abc.zip"));
byte[] b=new byte[4096];
while((offset=in1.read(b,0,4096))>-1){
sb.append(new String(b,0,offset,"UTF-8"));
bos.write(b, 0, offset);
}
bos.flush();
bos.close();

}

public void init() throws ServletException {
// Put your code here
}

}
