获取文档中心附件的下载地址，在IE直接打开并下载

MaHZ

//通过调用createAttachmentDowloadAddress()方法获取该附件的下载地址
1.fattachment 是这种格式的
String fattachment = "[{"docID":"C60B2322B74000019A5ED0805620CB70","docName":"hello.png","size":8918588,"fileID":"16-defaultDocNameSpace","docPath":"/defaultDocNameSpace/B7DD46ED17C54C778E9EF8A0E4F0B8D6/85FB6C51B02C4B59BEBF55C35990EB12","time":"2014-02-19T17:40:26.159Z"}]";  

2.我把docInfo变成了这种格式
String docInfo ={"docID":"C60B2322B74000019A5ED0805620CB70","docName":"hello.png","size":8918588,"fileID":"16-defaultDocNameSpace","docPath":"/defaultDocNameSpace/B7DD46ED17C54C778E9EF8A0E4F0B8D6/85FB6C51B02C4B59BEBF55C35990EB12","time":"2014-02-19T17:40:26.159Z"}

3.我把docInfo变成了一个json对象，并获取到docPath，fileID的值

4.根据帖子中4楼的做法，导入DocAdapter，调用queryNoPermissionHost(Boolean isHttps, String docPath, String urlPattern, Boolean isFormAction)方法（没有限制权限
java代码实现上传文件到文档服务器、下载文档服务器文件http://bbs.justep.com/forum.php?mod=viewthread&tid=40457


5.关于urlPattern的值我是看了看 \system\service\doc\docUtil.js中的
getURLByFileID : function(docPath, fileID, versionID, partType) {
                var versionID = versionID ? versionID : "last";
                var partType = partType ? partType : "content";
                return this.getdocServerAction(docPath, "/repository/file/download/" + fileID + "/" + versionID + "/" + partType );        }       
这些代码才得出的

6.得到的docUrl是这样的
/UI/system/service/doc/common/uploadDoc.j?dochost=http://localhost:8080/DocServer/repository/file/download/18-defaultDocNameSpace/last/content?key=63b386a3db4f2e24be757335b7a5fb8b9d566a602463c1becb09ca378a0a8294f354cb841844dc7f16fc336669bb60037455b6a122dfc69f27bf84c5d16a8511a02f8d2ad476cf3a5aab6cd57d647193afa74a58262fd3d1424f21972204e88f98d75f643e21183fb189a56812b5377f

7.然后我截取了一下，得到的
http://localhost:8080/DocServer/repository/file/download/18-defaultDocNameSpace/last/content?key=63b386a3db4f2e24be757335b7a5fb8b9d566a602463c1becb09ca378a0a8294f354cb841844dc7f16fc336669bb60037455b6a122dfc69f27bf84c5d16a8511a02f8d2ad476cf3a5aab6cd57d647193afa74a58262fd3d1424f21972204e88f98d75f643e21183fb189a56812b5377f

8.或得到的http://localhost:8080是你文档配置中文档服务器的地址 ，这样就能复制然后在地址栏里粘贴enter就会显示下载提示
public static String createAttachmentDowloadAddress(String fattachment) {
                String docUrl = null;
                try {
                        String docInfo = fattachment.substring(1, fattachment.length() - 1);
                        JSONObject obj = new JSONObject(docInfo);
                        String docPath = obj.get("docPath").toString();
                        String fileID = obj.get("fileID").toString();
                        docUrl = DocAdapter.queryNoPermissionHost(false, docPath,
                                        "/repository/file/download/" + fileID + "/last/content",
                                        true);
                } catch (Exception e) {
                        e.printStackTrace();
                }
                return docUrl.substring(50);
        }
