各种文件上传类型设置，实战示例

网页上添加一个input file HTML控件：
<input id="File1" type="file" />
默认是这样的，所有文件类型都会显示出来，如果想限制它只显示我们设定的文件类型呢，比如“word“,”excel“,”pdf“文件　
解决办法是可以给它添加一个accept属性，比如：
<input id="File1" type="file" accept=".xls,.doc,.txt,.pdf" />
这样选择的时候默认会显示为.xls,.doc,.txt,.pdf：
文件选择框内只显示出你自定义文件类型的文件，也还比较方便。
这只是最简单的掩人耳目的做法，还是能选择其它文件类型。
所以，如果要做到真正意义上限制类型做法（其实这种算不上限制，只是把你要的文件类型默认显示出来而已，并不是说不能选择其它的），还是要通过js或者后台来控制。

下面是ogg zip 的实战示例：
--------------------------------------------------
*.ogg application/ogg， audio/ogg Ogg Vorbis

$fileMIME = $file['type'];
switch ($fileMIME)
{
case 'application/ogg':
$tmpFile = $this->generateDir($modelFileBaseDir).$fileName.'.Ogg';
break;
case 'audio/ogg':
$tmpFile = $this->generateDir($modelFileBaseDir).$fileName.'.Ogg';
break;
case 'ogg':
$tmpFile = $this->generateDir($modelFileBaseDir).$fileName.'.Ogg';
break;
--------------------------------------------------
*.zip aplication/zip Compressed Archive

$fileMIME = $file['type'];
switch ($fileMIME)
{
case 'application/x-zip-compressed':
$tmpFile = $tmpFileDir.$fileName.'.ZIP';
break;
case 'aplication/zip':
$tmpFile = $tmpFileDir.$fileName.'.ZIP';
break;
-------------------------------------------------

Map<String, String> textMap = new HashMap<String, String>();

String ret = formUpload(url, textMap, fileMap,contentType);
System.out.println(ret);
}
