关于批量预览下载的问题

jishuang

String urlPattern = "/repository/file/download/" + fileID + "/last/content";
                String url = DocUtils.getDocUrl(docPath, urlPattern);

获取的url直接运行就是下载

DemonHuan

那下载到哪里了？ 不应该是下载到某个地方吗？ 怎么查看下载到哪里了？

jishuang

客户端下载是浏览器控制的下载到什么地方的。平台API只是提供下载的url

如果是java中下载那是服务端下载可以自己指定位置，4楼链接中就有案例

DemonHuan

我使用平台给的方法：
Docs docs = new Docs();
Doc doc = (Doc) docs.query(null, docPath, null, null, null).get(docid);
File outPutFile = new File("f:/"+((AbstractDoc) doc).getsDocName());               
((AbstractDoc) doc).download(new FileOutputStream(outPutFile));

报错：

导入的Doc类不正确

修改导入的类以后报错如下：

谢谢各位，已完美解决。 请结贴！

还有一个问题，这个附件下载的是服务器本地的盘符下，我怎么能下载的时候选择，然后下载到我自己的电脑上呢？

13楼已经说了客户端下载是浏览器控制的，调用API获取url给客户端访问
