为了实现转发发送者根据 XDMS 中存储的访问权限文档中的权限设置 将文档内容有选择性地转发给转发接收者， 从而避免了转发发送者在拥有转 发权限之后对文档的任意转发， 保证文档创建者对文档的保密性， 本发明实 施例提供了一种 XDM中转发文档内容的方法， 具体内容如下：
本发明实施例提出的在 XDM中实现内容选择性地转发给转发接收者的 方法， 其中， 对于有选择性的转发可以采用两种方法： 一种为在访问权限中 为有转发权限的转发发送者设置其可以转发的转发接收者的 URI ( Uniform Resource Identifier, 统一资源标示符）， 同时也可以设置转发的次数； 另一种 为如果拥有转发权限的转发发送者在转发文档时，将转发接收者的 URI发送 给 XDMS， XDMS到访问权限文档中验证该 URI是否拥有访问该文档内容的 权限， 其中以用户 A为文档管理用户， 用户 B为转发发送者， 用户 C为转 发接收者为例， 参见图 2， 具体流程如下：
201 : 用户 B向 XDMS发送请求， 请求将用户 A的部分文档内容转发给 用户 C在 XDMS的目录下；
其中， 本发明实施例中用户 A为文档管理用户， 用户 B为转发发送者， 用户 C为转发接收者， 用户 B请求将用户 A的部分文档内容转发给用户 C 在 XDMS的目录下；用户 A作为文档管理用户，可以是 XML文档的创建者， 也可以是一个被授权且可以修改文档的访问权限的特殊用户， 其他用户可以 根据管理者用户 A设定的访问权限， 访问 XDMS中的整个文档或者文档的 部分内容；
用户 B位于 XDMC ( Extensible Markup Language Document Management Client, 可扩展标记语言文档管理客户端）， 向 XDMS发送请求， 请求将用户 A的部分文档内容转发给用户 C在 XDMS的目录下， 也可以是将用户 A的 整个文档内容， 但必须用户 B拥有转发整个文档内容的权限时， 才可以向用 户 A请求将整个文档内容转发给用户 C。
202: XDMS接收到请求后， 获取用户 A的权限文档， 并判断用户 B是 否有转发权限以及判断用户 C是否有该文档内容的权限；如果用户 B有转发 权限且用户 C有该文明当内容的权限， 执行步骤 204; 否则， 执行步骤 203; 具体如下：
其中， XDMS在接收到请求后， 首先在 XDMS中获取用户 A的访问权 限文档， 在访问权限文档中查看用户 B是否有转发的权限； 其次， 当用户 B 拥有访问权限时， 获取用户 B能否将其拥有权限的文档内容转发给用户 C， 其中该转发过程是将 XDMS 中用户 B 能够访问的用户 A 的内容转发到 XDMS中用户 C的路径下， 而不是转发到用户 C拥有的 XDM用户 C;
其中，对于用户 A的访问权限文档中用户 B的转发权限的存储和设置以 及用户 B能否转发给用户 C具体有两种存储和设置方法：
( 1 )用户 A的权限文档中设置用户 B拥有转发权限时， 也设置用户 B 可以转发的转发接收者；如果用户 A的权限文档中对于用户 B的转发接收者 中不包括用户 C， 则 XDMS执行步骤 203; 如果用户 A的权限文档中对于用 户 B的转发接收者中包括用户 C， 则 XDMS执行步骤 204;
其中，在设置用户 B可以转发的转发接收者时还可以设置用户 B的转发 的次数对用户 B进行限制；还可以设置用户 B的转发内容， 即用户 B拥有文 档转发权限， 但可能只有文档的部分内容的转发权限， 这样用户 B只能转发 其拥有转发权限的那部分内容； 同样， 还可以设置用户 C的接收内容， 该接 收内容可以是用户 B拥有转发权限的部分文档内容也可以是用户 B拥有转发 权限的整个文档内容。
其中， 转发接收者在访问权限文档中设置的方法有以下六种，
〈一〉、在动作 <actions〉元素中的转发操P^<allow-forwarding〉it素下增力口 子元素 <receipt〉， 用来表示允许转发的接收者。
如： <document-mle path="/group 1 ">
<cp:ruleset>
<cp:rule cp:id="al ">
<cp:conditions>
<is-member/>
<paths>
<path id="group/listservice/list"/>
<path id="group/listservice/subj ect"/>
<path id="group/listservice/schedule"/>
</paths> </cp:conditions>
<cp:actions>
<allow-forwarding attribute="true">
<receipt>
<identity>
<one uri="sip:bob@example"/>
<one uri="sip:alice@example"/>
</ identity>
</receipt>
</allow-forwarding>
</cp:actions>
</cp:rule>
</cp:ruleset>
</document-rule>
<二〉、在动作 <actions〉元素中的转发操P^<allow-forwarding〉it素下 力口子元素 <non-receipt〉， 用来表示禁止接收者
如： <document-mle path="/group 1 ">
<cp:ruleset>
<cp:rule cp:id="al ">
<cp:conditions>
<is-member/>
<paths>
<path id="group/listservice/list"/>
<path id="group/listservice/subj ect"/>
<path id="group/listservice/schedule"/>
</paths>
</cp:conditions>
<cp:actions>
<allow-forwarding attribute="true">
<non-receipt>
<identity>
<one uri="sip:david@example"/>
<one uri="sip:tom@example"/>
</ identity>
</non-receipt>
</allow-forwarding>
</cp:actions>
</cp:rule> </cp:ruleset>
</document-rule>
〈三 >、 在一个条件 <conditions〉元素下定义转发的接收者和转发的发送 描述转发的发送者和转发的接收者。
如：
<document-rule path= "/group 1">
<cp:ruleset>
<cp:rule cp:id="al ">
<cp:conditions>
<sender>
<is-member/>
</sender>
<receipt>
<identity>
<one uri="bob@example.com"/>
<one uri="alice@example.com"/>
</identity>
</receipt>
<paths>
<path id="group/listservice/list"/>
<path id="group/listservice/subj ect"/>
<path id="group/listservice/schedule"/>
</paths>
</cp:conditions>
<cp:actions>
<allow-forwarding>true</allow-forwarding>
</cp:actions>
</cp:rule>
</cp:ruleset>
</document-rule>
<四〉、 在一个条件<001^^01 8〉元素下定义禁止的接收者和允许的发送 用来描述允许的发送者和禁止的接收者。 '、
如：
<document-rule path= "/group 1">
<cp:ruleset>
<cp:rule cp:id="al "> <cp:conditions>
<sender>
<is-member/>
</sender>
<non-receipt>
<identity>
<one uri="david@example.com"/>
<one uri="tom@example.com"/>
</identity>
</non-receipt>
<paths>
<path id="group/listservice/list"/>
<path id="group/listservice/subj ect"/>
<path id="group/listservice/schedule"/>
</paths>
</cp:conditions>
<cp:actions>
<allow-forwarding>true</allow-forwarding>
</cp:actions>
</cp:rule>
</cp:ruleset>
</document-rule>
<五〉、 在不同的条件 <conditions〉元素下定义转发接收者和转发发送者， 并且将转发发送者和转发接收者进行关联。 即在一个 01^ 01 8；>下定义
<sender> , 在另一个<∞1 (1^01 8〉下定义 <receipt〉。 其中， 转发发送者和转发 接收者关联的方法有两种， 一种用 <mle^々属性值 id进行关联， 如果 id值相 同，则证明为同一个转发操作下的转发发送者和转发接收者； 另一种方法为： 在<001^^01 8〉元素下定义转发发送者时， 将转发接收者进行关联
如例 1 :
<document-rule path= "/group 1 ">
<cp:ruleset>
<cp:rule cp:id="al ">
<cp:conditions>
<sender>
<is-member/>

203： XDMS向用户 B返回 409用户 Conflict错误响应；
204: XDMS向用户 B返回 200 OK响应， 允许用户 B将用户 A的部分 文档内容转发给用户 C， 并执行步骤 205；
205: XDMS将用户 A的文档中用户 B有权限转发给用户 C的内容转发 到 XDMS中用户 C的路径下。
上述处理过程中，还可以设置用户 B的访问权限内容包括转发内容以及 用户 C的访问权限内容， 即用户 B拥有文档转发权限，但可能只有文档的部 分内容的转发权限， 这样用户 B只能转发其拥有转发权限的那部分内容。 如 的权限文档中拥有访问权限的文档内容不同， 则 XDMS "在用户 A的权限

本发明实施例提供的方法，通过 XDMS在设置转发发送者的转发权限时 同时设置其可以转发的转发接收者或者 XDMS 在收到转发发送者发送转发 请求时先到权限文档中获取该转发接收者是否有权限访问该文档内容， 解决 了转发发送者根据 XDMS 中存储的访问权限文档中的权限设置将文档内容 有选择性地转发给转发接收者， 从而避免了转发发送者在拥有转发权限之后 对文档的任意转发， 也保证了文档创建者对文档的保密性。 实施例 3
为了实现转发发送者根据 XDMS 中存储的访问权限文档中的权限设置 将文档内容有选择性地转发给转发接收者， 避免转发发送者在拥有转发权限 之后对文档的任意转发， 保证文档创建者对文档的保密性， 本发明实施例提 供了一种 XDM中转发文档内容的方法， 具体内容如下：
本发明实施例中以用户 A为文档管理用户， 用户 B为转发发送者， 用户 C为转发接收者为例， 用户 B将在用户 A (文档内容存储在 XDMS ) 中有权 限转发的文档内容转发给用户 C(转发内容存储在 XDMS )，所以位于 XDMC 的用户 B向 XDMS发送请求， 根据用户 A权限文档中设置的转发接收者来 判断是否允许用户 C访问该文档， 如果用户 C有权限的话，服务器将该内容 转发给用户 C。 参见图 3， 具体步骤如下：
301 : 位于 XDMC的用户 B向 XDMS发送 GET请求， 请求将用户 B在 用户 A的文档中拥有转发权限的文档内容转发给用户 C;
其中，用户 B向 XDMS发送 GET请求，这里的 GET请求仅代表获取这 个动作， 它与修改、 删除、 创建是并列的操作， 并不对内容进行处理过程； 其中， 用户 B位于 XDMC， 用户 A的文档内容存放在 XDMS中； 用户 A作为文档管理用户， 可以是 XML文档的创建者， 也可以是一个被授权且 可以修改文档的访问权限的特殊用户，其他用户可以根据管理者用户 A设定 的访问权限， 访问 XDMS中的整个文档或者文档的部分内容；
用户 B向 XDMS发送请求中， 请求将用户 B在用户 A的文档中拥有转 发权限的文档内容转发给用户 C在 XDMS的目录下， 当用户 B拥有转发整 个文档内容的权限时， 也可以向用户 A请求将整个文档内容转发给用户 C; 另外， 用户 B也可以将用户 B在用户 A的文档中拥有转发权限的文档内容 中的部分内容转发给用户 C。
302: XDMS在接收到用户 B发送的请求后， 获取用户 A的权限文档中 对于用户 B拥有的访问权限， 判断用户 B是否有转发权限， 如果是， 执行步 骤 303; 否则， 执行步骤 306;
303: XDMS在用户 A的权限文档中判断用户 C是否在用户 B的转发接 收者列表中， 如果是， 则执行步骤 304; 否则， 执行步骤 306;
其中，本发明实施例中用户 A的权限文档中如果允许某个用户拥有转发 权限转发文档内容时， 需设置其对应的转发接收者， 建立转发接收者列表， 将所有可以转发的用户都放在该列表中。
304: XDMS向用户 B返回 200 OK响应， 通知用户 A允许用户 B将用 户 B在用户 A的文档中拥有权限的文档内容转发给用户 C，并执行步骤 305;
305: XDMS将用户 B在用户 A的权限文档中拥有转发权限的文档内容 转发给用户 C;
306: XDMS向用户 B返回 409用户 Conflict响应， 通知用户 A禁止将 文档内容转发给用户 c。
另夕卜，在设置用户 B可以转发的转发接收者时还可以设置用户 B的转发 的次数对用户 B进行限制； 上述处理过程中， 还可以设置用户 B的访问权限 内容包括转发内容以及用户 C的访问权限内容，即用户 B拥有文档转发权限， 但可能只有文档的部分内容的转发权限， 这样用户 B只能转发其拥有转发权 限的那部分内容。如果用户 B在用户 A的权限文档中拥有转发权限的文档内 容与用户 C在用户 B的转发接收者列表中拥有访问权限的文档内容不同，则 XDMS将在用户 A的权限文档中用户 B既拥有转发权限且用户 C拥有访问 权限的文档内容发送给用户 C。
本发明实施例提供的方法，通过 XDMS在设置转发发送者的转发权限时 同时设置其可以转发的转发接收者，实现了转发发送者根据 XDMS中存储的 访问权限文档中的权限设置将文档内容有选择性地转发给转发接收者， 从而 避免了转发发送者在拥有转发权限之后对文档的任意转发， 也保证了文档创 建者对文档的保密性。 实施例 4
为了实现转发发送者根据 XDMS 中存储的访问权限文档中的权限设置 将文档内容有选择性地转发给转发接收者， 避免转发发送者在拥有转发权限 之后对文档的任意转发， 保证文档创建者对文档的保密性， 本发明实施例提 供了一种 XDM中转发文档内容的方法， 具体内容如下：
本发明实施例中以用户 A为文档管理用户， 用户 B为转发发送者， 用户 C为转发接收者为例， 用户 B将在用户 A (文档内容存储在 XDMS ) 中有权 限转发的文档内容转发给用户 C(转发内容存储在 XDMS )，所以位于 XDMC 的用户 B向 XDMS发送请求。 在本发明实施例中用户 A的权限文档中没有 户 C是否有权限访问该文档'，从而判断用户 B、能否转发给用户 C，参见图 4， 具体步骤如下：
401 : 位于 XDMC的用户 B向 XDMS发送 GET请求， 向用户 A请求用 户 B是否有转发权限以及用户 C是否有访问该文档内容的权限；
其中， 位于 XDMC用户 B向 XDMS发送 GET请求， 这里的 GET请求 仅代表获取这个动作， 它与修改、 删除、 创建是并列的操作， 并不对内容进 行处理过程；
其中， 用户 A的文档内容存放在 XDMS中， 用户 A作为文档管理用户， 可以是 XML文档的创建者， 也可以是一个被授权且可以修改文档的访问权 限的特殊用户，其他用户可以根据管理者用户 A设定的访问权限，访问 XDMS 中的整个文档或者文档的部分内容；
用户 B向 XDMS发送请求中， 请求将用户 B在用户 A的文档中拥有转 发权限的文档内容转发给用户 C在 XDMS的目录下， 当用户 B拥有转发整 个文档内容的权限时， 也可以向用户 A请求将整个文档内容转发给用户 C; 另外， 用户 B也可以将用户 B在用户 A的文档中拥有转发权限的文档内容 中的部分内容转发给用户 C。
402: XDMS接收到用户 B的 GET请求后，到用户 A的权限转发发送者 B的转发权限以及用户 C的访问权限；
其中， XDMS接收到用户 B发送的请求后， 获取用户 A的权限文档， 根据用户 A的权限文档判断用户 B是否有转发权限， 当用户 B有转发权限 时， 由于权限文档中没有设置拥有转发权限的用户的转发接收者的权限， 而 收者， 即如果在权限转发发送者中包括转发接收者 C的 lRI， 则可以进行转 发， 但是若在权限转发发送者中不包括转发接收者 C的 URI， 则不可以进行 转发；
XDMS获取用户 A的权限文档， 在权限文档中判断用户 B没有转发权 限或者在权限转发发送者中不包括转发接收者 C的 URI， 则向用户 B返回 409用户 Conflict响应， 通知用户 A禁止将文档内容转发给用户 C。
403: 当 XDMS判断用户 B有转发的权限并且用户 C也拥有访问该文档 的权限， 则向 XDMC返回 200 OK响应；
其中， 用户 C拥有访问该文档的权限即拥有被转发的权限， XDMS 向 XDMC返回 200 OK响应， 在该响应中可以包括转发的文档内容。
404: 用户 B向 XDMS发送 GET请求，请求将部分文档内容转发给用户
C;
405: XDMS接收到该请求后， 继续根据用户 A的权限文档判断可否转 发给用户 判断结果为可以转发；
其中， XDMS接收到该请求后， 继续根据用户 A的权限文档判断用户 C 在用户 A的权限文档是否拥有访问权限， 即在权限转发发送者中是否包括转 发接收者 C的 URI， 判断结果为可以进行转发。
406: XDMS将用户 B在用户 A的文档中拥有转发权限的文档内容转发 给用户 C。
另外，在设置用户 B的转发权限时还可以设置用户 B的转发的次数对用 户 B进行限制。
上述处理过程中，还可以设置用户 B的访问权限内容包括转发内容以及 用户 C的访问权限内容， 即用户 B拥有文档转发权限，但可能只有文档的部 分内容的转发权限， 这样用户 B只能转发其拥有转发权限的那部分内容。 如 果用户 B在用户 A的权限文档中拥有转发权限的文档内容与用户 C在位于 XDMS的用户 A的权限文档中拥有访问权限的文档内容不同， 则 XDMS将 在用户 A的权限文档中用户 B既拥有转发权限且用户 C拥有访问权限的文 档内容发送给用户 C。
例如： 文档内容包括 1、 2、 3三部分， 而用户 B在用户 A的权限文档中 拥有转发权限的文档内容为 1、 2， 用户 C在用户 A的权限文档中拥有访问 权限的文档内容为 1， 则 XDMS在根据用户 A的权限文档中判断用户 B有 转发权限且用户 C拥有访问权限后， 将文档内容 1转发给用户 C， 虽然用户 B拥有转发权限的文档内容为 1、 2， 但由于用户 C在用户 A的权限文档中 拥有访问权限的文档内容仅为 1， 所以 XDMS只能将文档内容 1转发给用户 C;
又如： 文档内容包括 1、 2、 3三部分， 而用户 B在用户 A的权限文档中 拥有转发权限的文档内容为 2， 用户 C在用户 A的权限文档中拥有访问权限 的文档内容为 2、 3， 则 XDMS在根据用户 A的权限文档中判断用户 B有转 发权限且用户 C拥有访问权限后， 将文档内容 2转发给用户 C， 虽然用户 C 拥有访问权限的文档内容为 2、 3，但由于用户 B拥有转发权限的文档内容仅 为 2， 所以 XDMS只能将文档内容 2转发给用户 C;
再如： 文档内容包括 1、 2、 3三部分， 而用户 B在用户 A的权限文档中 拥有转发权限的文档内容为 1、 2、 3， 用户 C在用户 A的权限文档中拥有访 问权限的文档内容为 3， 则 XDMS在根据用户 A的权限文档中判断用户 B 有转发权限且用户 C拥有访问权限后， 将文档内容 3转发给用户 C， 虽然用 户 B拥有转发权限的文档内容为 1、 2、 3， 但由于用户 C在用户 A的权限文 档中拥有访问权限的文档内容仅为 3， 所以 XDMS只能将文档内容 3转发给 用户 C。
本发明实施例提供的方法，通过 XDMS在收到转发发送者发送转发请求 时到权限文档中获取转发发送者是否拥有转发权限时同时获取该转发接收者 是否有权限访问该文档内容，实现了转发发送者根据 XDMS中存储的访问权 限文档中的权限设置将文档内容有选择性地转发给转发接收者， 从而避免了 转发发送者在拥有转发权限之后对文档的任意转发， 也保证了文档创建者对 文档的保密性。 实施例 5
为了实现转发发送者根据 XDMS 中存储的访问权限文档中的权限设置 将文档内容有选择性地转发给转发接收者， 避免转发发送者在拥有转发权限 之后对文档的任意转发， 保证文档创建者对文档的保密性， 本发明实施例提 供了一种 XDM中转发文档内容的方法， 具体内容如下：
本发明实施例中以用户 A为文档管理用户， 用户 B为转发发送者， 用户 C为转发接收者为例， 用户 B将在用户 A (文档内容存储在 XDMS ) 中有权 限转发的文档内容转发给用户 C(转发内容为文档内容中的全部或者一部分， 存储在 XDMS )， 所以位于 XDMC的用户 B向 XDMS发送请求。 在本发明 实施例中用户 A的权限文档中没有设置转发接收者权限， 但是在 XDMS要 求对于拥有转发权限的用户在要转发文档内容时，需要向文档管理用户 A进 行询问， 询问转发接收者是否有接收文档内容的权限， 如果有权限则发送， 没有权限则向转发发送者 B返回错误， 禁止发送。 参见图 5， 具体步骤如下：
501 : 位于 XDMC的用户 B向 XDMS发送 GET请求， 向用户 A询问用 户 B是否可以将文档内容转发给用户 C;
其中， 位于 XDMC用户 B向 XDMS发送 GET请求， 这里的 GET请求 仅代表获取这个动作， 它与修改、 删除、 创建是并列的操作， 并不对内容进 行处理过程；
其中， 用户 A的文档内容存放在 XDMS中， 用户 A作为文档管理用户， 可以是 XML文档的创建者， 也可以是一个被授权且可以修改文档的访问权 限的特殊用户，其他用户可以根据管理者用户 A设定的访问权限，访问 XDMS 中的整个文档或者文档的部分内容；
用户 B向 XDMS发送请求中， 请求将用户 B在用户 A的文档中拥有转 发权限的文档内容转发给用户 C在 XDMS的目录下， 当用户 B拥有转发整 个文档内容的权限时， 也可以向用户 A请求将整个文档内容转发给用户 C; 另外， 用户 B也可以将用户 B在用户 A的文档中拥有转发权限的文档内容 中的部分内容转发给用户 C。
502: XDMS接收到用户 B的 GET请求后，到用户 A的权限文档中获取 用户 B的转发权限；
其中， XDMS接收到用户 B发送的请求后， 获取用户 A的权限文档， 根据用户 A的权限文档判断用户 B是否有转发权限， 当用户 B有转发权限 时执行步骤 503;
XDMS获取用户 A的权限文档， 如果在权限文档中判断用户 B没有转 发权限， 则向用户 B返回 409用户 Conflict响应， 通知用户 A禁止将文档内 容转发给用户 C。
503: 当用户 B在用户 A的权限文档中有转发权限时， XDMS 向位于 XDMC的用户 A询问是否可以将用户 B拥有转发权限的文档内容转发给用 户 C;
其中， 用户 A的权限文档中没有设置转发接收者权限， 但是在 XDMS 要求对于拥有转发权限的用户在要转发文档内容时， 需要向文档管理用户 A 进行询问， 询问转发接收者 C是否有接收文档内容的权限。
504: XDMC的用户 A判断可以转发， 并将结果返回给 XDMS;
、 、 其中， XDMC的用户 A接 到 XDMC发送的询 J3]^求时， 判断是否可 果有权限则可以转发， 没有权限则向转发发送者 B返回错误， 禁止发送。
505: XDMS向用户 B返回 200 OK, 通知 B可以将用户 B拥有转发权 限的文档内容转发给用户 C;
506: XDMS将用户 B拥有转发权限的文档内容转发给用户 C。
另外，在设置用户 B的转发权限时还可以设置用户 B的转发的次数对用 户 B进行限制。
上述处理过程中，还可以设置用户 B的访问权限内容包括转发内容以及 位于 XDMC的用户 A中用户 C的访问权限内容， 即用户 B拥有文档转发权 限， 但可能只有文档的部分内容的转发权限， 这样用户 B只能转发其拥有转 发权限的那部分内容。如果用户 B在用户 A的权限文档中拥有转发权限的文 档内容与用户 C在位于 XDMC的用户 A中的访问权限的文档内容不同， 则 XDMS将在位于 XDMS的用户 A的权限文档中用户 B拥有转发权限的文档 内容且用户 C在位于 XDMC的用户 A中的访问权限的文档内容发送给用户 C。
例如： 文档内容包括 1、 2、 3三部分， 而用户 B在用户 A的权限文档中 拥有转发权限的文档内容为 1、 2， 用户 C在位于 XDMC的用户 A中的访问 权限的文档内容为 1， 则 XDMS在根据用户 A的权限文档中判断用户 B有 转发权限且位于 XDMC的用户 A判断用户 C拥有访问权限后， 将文档内容 1转发给用户 C， 虽然用户 B拥有转发权限的文档内容为 1、 2， 但由于用户 C在位于 XDMC的用户 A中的访问权限的文档内容仅为 1， 所以 XDMS只 能将文档内容 1转发给用户 C;
又如： 文档内容包括 1、 2、 3三部分， 而用户 B在用户 A的权限文档中 拥有转发权限的文档内容为 2， 用户 C在位于 XDMC的用户 A中的访问权 限的文档内容为 2、 3， 则 XDMS在根据用户 A的权限文档中判断用户 B有 转发权限且位于 XDMC的用户 A判断用户 C拥有访问权限后， 将文档内容 2转发给用户 C， 虽然用户 C在位于 XDMC的用户 A中的访问权限的文档 内容为 2、 3， 但由于用户 B拥有转发权限的文档内容仅为 2， 所以 XDMS 只能将文档内容 2转发给用户 C;
再如： 文档内容包括 1、 2、 3三部分， 而用户 B在用户 A的权限文档中 拥有转发权限的文档内容为 1、 2、 3， 用户 C在位于 XDMC的用户 A中的 访问权限的文档内容为 3，则 XDMS在根据用户 A的权限文档中判断用户 B 有转发权限且位于 XDMC的用户 A判断用户 C拥有访问权限后， 将文档内 容 3转发给用户 C， 虽然用户 B拥有转发权限的文档内容为 1、 2、 3， 但由 于用户 C在位于 XDMC 的用户 A 中的访问权限的文档内容仅为 3， 所以 XDMS只能将文档内容 3转发给用户 C。
本发明实施例提供的方法， 通过 XDM服务器在收到转发发送者发送转 发请求时获取转发发送者的转发权限并向文档管理者询问转发接收者是否有 权限访问该文档内容， 实现了转发发送者根据 XDM服务器中存储的访问权 限文档中的权限设置将文档内容有选择性地转发给转发接收者， 从而避免了 转发发送者在拥有转发权限之后对文档的任意转发， 也保证了文档创建者对 文档的保密性。 实施例 6
为了实现转发发送者根据 XDMS 中存储的访问权限文档中的权限设置 将文档内容有选择性地转发给转发接收者， 避免转发发送者在拥有转发权限 之后对文档的任意转发， 保证文档创建者对文档的保密性， 本发明实施例提 供了一种 XDM中转发文档内容的方法， 具体内容如下：
本发明实施例中以用户 A为文档管理用户， 用户 B为转发发送者， 用户 C为转发接收者为例， 用户 B将在用户 A (文档内容存储在 XDMS ) 中有权 限转发的文档内容转发给用户 C(转发内容存储在 XDMS )，所以位于 XDMC 的用户 B向 XDMS发送请求， 根据 A权限文档中设置的禁止接收者来判断 用户 C是否被禁止访问该文档内容， 如果用户 C被禁止，服务器将不会转发 该文档内容给用户 C， 并且向用户 B返回错误响应。 该实施例中要求用户 A 的权限文档中如果允许某一用户转发文档内容时， 需设置转发时禁止的接收 者， 转发次数， 转发的内容。 参见图 6， 具体步骤如下：
601 : 位于 XDMC的用户 B向 XDMS发送 GET请求， 请求将用户 B在 用户 A的文档中拥有转发权限的文档内容转发给用户 C; 其中，用户 B向 XDMS发送 GET请求，这里的 GET请求仅代表获取这 个动作， 它与修改、 删除、 创建是并列的操作， 并不对内容进行处理过程； 其中， 用户 B位于 XDMC， 用户 A的文档内容存放在 XDMS中； 用户 A作为文档管理用户， 可以是 XML文档的创建者， 也可以是一个被授权且 可以修改文档的访问权限的特殊用户，其他用户可以根据管理者用户 A设定 的访问权限， 访问 XDMS中的整个文档或者文档的部分内容；
用户 B向 XDMS发送请求中， 请求将用户 B在用户 A的文档中拥有转 发权限的文档内容转发给用户 C在 XDMS的目录下， 当用户 B拥有转发整 个文档内容的权限时， 也可以向用户 A请求将整个文档内容转发给用户 C; 另外， 用户 B也可以将用户 B在用户 A的文档中拥有转发权限的文档内容 中的部分内容转发给用户 C。
602: XDMS在接收到用户 B发送的请求后， 获取用户 A的权限文档中 对于用户 B拥有的访问权限， 判断用户 B是否有转发权限；
其中， XDMS在用户 A的权限文档中判断判断用户 B没有转发权限时， XDMS向用户 B返回 409用户 Conflict响应，通知用户 A禁止将文档内容转 发给用户 C。
603: 当用户 B有转发权限时， XDMS在用户 A的权限文档中判断用户 C是否在用户 B的禁止转发接收者列表中；
其中，本发明实施例中用户 A的权限文档中如果允许某个用户拥有转发 权限转发文档内容时， 需设置其对应的禁止转发接收者， 建立禁止转发接收 者列表， 将所有禁止转发的用户都放在该列表中。
XDMS在用户 A的权限文档中判断用户 C在用户 B的禁止转发接收者 列表中， XDMS向用户 B返回 409用户 Conflict响应， 通知用户 A禁止将文 档内容转发给用户 C。
604: XDMS在用户 A的权限文档中判断用户 C不在用户 B的禁止转发 接收者列表中， XDMS向用户 B返回 200 OK响应， 通知用户 A允许用户 B 将用户 B在用户 A的文档中拥有权限的文档内容转发给用户 C;
605: XDMS将用户 B在用户 A的权限文档中拥有转发权限的文档内容 转发给用户 C。
其中，在设置用户 B禁止转发的转发接收者时还可以设置用户 B的转发 的次数对用户 B进行限制； 上述处理过程中， 还可以设置用户 B的访问权限 内容包括转发内容即用户 B拥有文档转发权限。
本发明实施例提供的方法，通过 XDMS在设置转发发送者的转发权限时 同时设置其禁止转发的接收者，实现了转发发送者根据 XDMS中存储的访问 权限文档中的权限设置将文档内容有选择性地转发给转发接收者， 从而避免 了转发发送者在拥有转发权限之后对文档的任意转发， 也保证了文档创建者 对文档的保密性。 实施例 Ί
为了实现转发发送者根据 XDMS 中存储的访问权限文档中的权限设置 将文档内容有选择性地转发给转发接收者， 避免转发发送者在拥有转发权限 之后对文档的任意转发， 保证文档创建者对文档的保密性， 本发明实施例提 供了一种 XDM中转发文档内容的方法， 具体内容如下：
本发明实施例中以用户 Α为文档管理用户， 用户 B为转发发送者， 用户 C为转发接收者为例， 用户 B将在用户 A (文档内容存储在 XDMS ) 中有权 限转发的文档内容转发给用户 C(转发内容存储在 XDMS )，所以位于 XDMC 的用户 B向 XDMS发送请求， 在该实施例中用户 A的权限文档中既没有设 置转发发送者的权限， 也没有设置转发接收者权限， 但是当某一用户在向 XDMS发送请求， 请求转发某部分文档内容时， 需要向文档创建者或者文档 管理者进行询问， 询问转发发送者是否可以转发某部分文档内容， 并且询问 转发接收者是否有接收文档内容的权限， 如果两者都有权限则发送， 如果任 意一方没有权限则像文档获取方返回错误， 禁止发送。 参见图 7， 具体步骤 ^口下：
701 : 位于 XDMC的用户 B向 XDMS发送 GET请求， 向用户 A询问用 户 B是否可以将文档内容转发给用户 C;
其中， 位于 XDMC用户 B向 XDMS发送 GET请求， 这里的 GET请求 仅代表获取这个动作， 它与修改、 删除、 创建是并列的操作， 并不对内容进 行处理过程；
其中， 用户 A的文档内容存放在 XDMS中， 用户 A作为文档管理用户， 可以是 XML文档的创建者， 也可以是一个被授权且可以修改文档的访问权 限的特殊用户，其他用户可以根据管理者用户 A设定的访问权限，访问 XDMS 中的整个文档或者文档的部分内容；

702: XDMS接收到用户 B的 GET请求后，到用户 A的权限文档中获取 用户 B的转发权限和用户 C的接收权限，如果权限文档中既没有设置转发发 送权限， 也没有设置转发接收权限， 则执行步骤 703 ;
其中， XDMS接收到用户 B发送的请求后， 获取用户 A的权限文档， 判断用户 A的权限文档是否有用户 B的转发权限和用户 C的接收权限， 如 果权限文档中既没有设置转发发送权限， 也没有设置转发接收权限， 则执行 步骤 703;
703: XDMS向位于 XDMC的用户 A询问用户 B是否有转发发送以及 用户 C是否有转发接收权限； 其中，用户 A的权限文档中没有设置转发发送者的权限也没有设置转发 接收者权限， 需要 XDMS向文档管理用户 A进行询问， 询问用户 B是否拥 有转发权限以及转发接收者 C是否有接收文档内容的权限。
704: 当用户 A判断得出用户 B可以转发， 并且用户 C可以接收用户 B 拥有转发权限的文档内容， 则向 XDMS返回判断结果；
其中， 当用户 A判断用户 B不能转发， 或者用户 C不能接收用户 B拥 有转发权限的文档内容时， 则也向 XDMS返回判断结果， XDMS收到该判 断结果后， 向向用户 B返回 409用户 Conflict响应， 通知用户 A禁止将文档 内容转发给用户 C。
705: XDMS向用户 B返回 200 OK， 即表明用户 Β可以将拥有转发权限 的文档内容转发给用户 C;
706: XDMS将用户 B拥有转发权限的文档内容转发给用户 C。
上述处理过程中，还可以设置用户 B的访问权限内容包括转发内容即用 户 B拥有文档转发权限， 但可能只有文档的部分内容的转发权限， 这样用户 B只能转发其拥有转发权限的那部分内容。
本发明实施例提供的方法，通过 XDMS在收到转发发送者的转发请求后 向文档管理者发送询问请求， 询问转发发送者是否拥有转发权限以及转发接 收者是否拥有访问权限， 实现了转发发送者将文档内容有选择性地转发给转 发接收者， 从而避免了转发发送者在拥有转发权限之后对文档的任意转发， 也保证了文档创建者对文档的保密性。 实施例 8
