form 提交数据, 用InputStream fileSource=request.getInputStream()可以看到如下数据:
-----------------------------7da1e43850104
Content-Disposition: form-data; name="topic"
topic
-----------------------------7da1e43850104
Content-Disposition: form-data; name="kind"
kind
-----------------------------7da1e43850104
Content-Disposition: form-data; name="master"
master
-----------------------------7da1e43850104
Content-Disposition: form-data; name="depart"
topic
数据已经传过来了, 可是用
String fileTopic =request.getParameter("topic");
String fileKind =request.getParameter("kind");
String fileMaster =request.getParameter("master");
String fileDepart =request.getParameter("depart");
取的结果全是空NULL.
form中有没有定义这几个属性？
确定是同一个request，或者是被forward的request？
<form action="upload.jsp" enctype="MULTIPART/FORM-DATA" method=post>
选择上传文件<input type="file" name="DocumentID"><br>
文件主题<input name="topic" type="text" value="topic"><br>
文件类别<input name="kind" type="text" value="kind"><br>
