java servlet 如何获取form中的参数

servlet 如何获取form中的参数

Answer 1

你这样获取是正确，如果没获到，你看是不是提交给这个servlet了，
<form action="uploadMusic" id="fileUploadForm" name="fileUploadForm" method="post" enctype="multipart/form-data" >

或
<form action="uploadmusic" id="fileUploadForm" name="fileUploadForm" method="post" enctype="multipart/form-data" >
你试一下

Answer 2

最有可能的问题就是<form action="./uploadMusic" id="fileUploadForm" name="fileUploadForm" method="post" enctype="multipart/form-data" >里面的action="./uploadMusic"错误。你换个别的，比如../uploadMusic,或../../uploadMusic试试

Answer 3

request.getParameter("username");
