?*?Title:?Java?程序
?*?</p>
?*?<p>
?*?Description:?通用的請(qǐng)求處理程序，能夠處理上傳方式
?*?</p>
?*?
?*?<pre>
?*??一般使用方法如下
?*???<%
?*???指定編碼方式
?*???request.setCharacterEncoding("GBK");
?*???//?為
文件上傳
做準(zhǔn)備，該類讀取接口與?request?相同
?*???net.java2000.tools.Upload?upload?=?new?net.java2000.tools.Upload(request);
?*???//?解析
?*???upload.parse();
?*???%>
?*???...
?*???<%
?*???//使用標(biāo)準(zhǔn)方法讀取參數(shù)
?*???String?name?=?upload.getParameter("Name");
?*???String[]?names?=?upload.getParameterValues("nameMultiSelected");
?*???<br/>
?*???//?讀取上傳信息，比如上傳照片
?*???<form?method="POST"?name="form1"?enctype="multipart/form-data"?action=""?onsubmit="return?check();">
?*???<input?type="file"?name="photo"?size="8"?value="更新照片">
?*???</form>
?*???//?讀取表單值,也就是照片的實(shí)際信息,請(qǐng)注意，該方法名包含Org,和前面的不同
?*???//?由于上傳信息經(jīng)常是二進(jìn)制內(nèi)容，所以不能采用編碼后的字符串，應(yīng)采用和流完全對(duì)應(yīng)的字符串
?*???String?photo?=?upload.getParameterOrg("photo");??//?此方法讀取原始信息，沒有進(jìn)行任何編碼，即ISO-8859-1?格式
?*???//?如果轉(zhuǎn)化為字節(jié)數(shù)組為
?*???byte[]?bytes?=?photo.getBytes("iso-8859-1");
?*???//?讀取照片的類型
?*???String?contentType?=?upload.getContentType("photo");
?*???//?讀取照片文件名，不包含路徑
?*???String?filename?=?upload.getFilename("photo");
?*???%>
?*???請(qǐng)?jiān)诒M可能前的地方使用，特別是<b>不要</b>再使用了
?*???request.getParameter("XXX");
?*???后面使用，因?yàn)檫@時(shí)候的輸入流已經(jīng)被系統(tǒng)使用了。
