我目前正在尝试上传多个文件,并且文件正在上传到目标目录中.但在日志中它给了我这个错误:

java.io.FileNotFoundException: /home/sandeep/java_proj/jee_tut/files (Is a directory)

这是我上传文件的代码:

final String UPLOAD_DIR="files";

    String applicationPath="/home/sandeep/java_proj/jee_tut";
    String uploadDirPath= applicationPath + File.separator + UPLOAD_DIR;

    try{
        File fileDir=new File(uploadDirPath);
        if(!fileDir.exists()){
            fileDir.mkdirs(); …

我正在建立一个移动网站,在这里有一个表格,但没有提交按钮.因此,当用户在输入字段中键入内容并单击Android或iPhone GO按钮时,它应该提交表单.我正在使用HTML和jQuery.

如何在jQuery中捕获此GO事件？我希望它以自己的方式完成.

我一直试图在linux命令行中使用此命令将文件上传到服务器:

curl -v --data 'file=@/var/www/fbapp/images/registration.png' http://myserver/xmltest/curlupload.php

但它没有将文件上传到服务器,即使它正在发送响应.

虽然如果我使用此命令,它将上传文件并发回响应:

curl -v -F 'filename=registration.png' -F 'file=@/var/www/fbapp/images/registration.png' http://myserver/xmltest/curlupload.php

但我想要curl --data格式本身的命令.

这是我在服务器中的PHP代码:

<?php
$uploadpath = "images/";
$filedata = $_FILES['file']['tmp_name'];
echo "filedata= ".$filedata;
if ($filedata != '')
copy($filedata,$uploadpath."1.png");
echo "success";
?>

这是我得到的标题响应:
