Sae 上传文件到Storage

时间:2023-06-01 18:29:02

首先说一下几个地方:

1.上传使用ss.upload("domin域名","源地址","目标地址,也就是storage的地址");假设要上传到storage某一个详细的文件夹下目标地址写为"upload/"+filename;文件就上传到了upload文件夹下。

2.storage以下全部文件的路径是http://myapp-mybucket.stor.sinaapp.com/path/file.txt 
前面是myapp是应用的名字,这个路径能够通过

String realPath = ss.getUrl("域名", “上面的目标路径”); 就能够得到这个全网路径

3.使用commons-fileupload上传组件时,先把文件写到一个暂时路径里,然后再写回storage就好了。

以下是java代码:

<pre name="code" class="java">private void userSave(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {
FileItemFactory factory=new DiskFileItemFactory();
ServletFileUpload upload=new ServletFileUpload(factory);
List<FileItem> items=null;
try {
items=upload.parseRequest(request);
} catch (FileUploadException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Iterator<FileItem> itr=items.iterator(); HttpSession session=request.getSession(); User user=(User)session.getAttribute("currentUser");
//上传到Storage之后的真是路径
String realPath=user.getImageName();
String imageName=user.getImageName();
boolean imageChange=false;
<span style="white-space:pre"> </span>while(itr.hasNext()){
<span style="white-space:pre"> </span> FileItem item=(FileItem)itr.next();
<span style="white-space:pre"> </span> if(!item.isFormField()){
<span style="white-space:pre"> </span> try{
<span style="white-space:pre"> </span> imageName=DateUtil.getCurrentDateStr();
<span style="white-space:pre"> </span> //带后缀的文件名称
<span style="white-space:pre"> </span> imageName=imageName+"."+item.getName().split("\\.")[1];
<span style="white-space:pre"> </span> user.setImageName(imageName);
<span style="white-space:pre"> </span> //String filePath=PropertiesUtil.getValue("imagePath")+imageName+"."+item.getName().split("\\.")[1];
<span style="white-space:pre"> </span> String folder=PropertiesUtil.getValue("imagePath");
<span style="white-space:pre"> </span> String filePath=session.getServletContext().getRealPath(folder)+"/"+imageName;
<span style="white-space:pre"> </span>  <span class="comment" style="margin: 0px; padding: 0px; border: none; color: rgb(0, 130, 0); font-family: Consolas, 'Courier New', Courier, mono, serif; line-height: 18px;">//前面的部分仅仅须要按正常的上传来写就能够了 filePath仅仅是一个暂时文件</span><span style="margin: 0px; padding: 0px; border: none; font-family: Consolas, 'Courier New', Courier, mono, serif; line-height: 18px;">  </span>
<span style="white-space:pre">		</span>   <span style="color:#ff0000;">item.write(new File(filePath));</span>
// 上传完成后 使用SaeStorage往storage里面写
SaeStorage ss = new SaeStorage();
// 使用upload方法上传到域domain下,此处本人的是onway
<span style="color:#ff0000;">ss.upload("onway", filePath, <span style="font-family: Consolas, 'Courier New', Courier, mono, serif; line-height: 18px; background-color: rgb(248, 248, 248);">"upload/"</span>+imageName);</span>
// 获取上传后的图片路径
realPath = <span style="color:#ff0000;">ss.getUrl</span>("onway", <span style="color: rgb(0, 0, 255); font-family: Consolas, 'Courier New', Courier, mono, serif; line-height: 18px; background-color: rgb(248, 248, 248);">"upload/"</span>+imageName);
// System.out.println(realPath);
}catch(Exception e){
e.printStackTrace();
}
}
}
