Question

我正在尝试为我的应用程序开发一个简单的CalDAV服务器，在这方面我试图从日历客户端提供初始PROPFIND请求。

日历客户端请求服务器响应请求设置一组属性（如下所示）：

方法： PROPFIND / calendars / user / HTTP / 1.1

请求标题：

Accept-encoding  gzip, deflate
Accept  */*
Connection  keep-alive
Prefer  return=minimal
Host  192.168.0.12:8080
Brief  t
User-agent  Mac+OS+X/10.10.5 (14F27) CalendarAgent/316.1
Depth  0
Authorization  Basic YWRtaW46cGFzc3dvcmQ=
Accept-language  en-us
Content-type  text/xml
Content-length  743

请求正文：

<?xml version="1.0" encoding="UTF-8"?>
<A:propfind xmlns:A="DAV:">
 <A:prop>
   <B:calendar-home-set xmlns:B="urn:ietf:params:xml:ns:caldav"/>
   <B:calendar-user-address-set xmlns:B="urn:ietf:params:xml:ns:caldav"/>
   <A:current-user-principal/>
   <A:displayname/>
   <C:dropbox-home-URL xmlns:C="http://calendarserver.org/ns/"/>
   <C:email-address-set xmlns:C="http://calendarserver.org/ns/"/>
   <C:notification-URL xmlns:C="http://calendarserver.org/ns/"/>
   <A:principal-collection-set/>
   <A:principal-URL/>
   <A:resource-id/>
   <B:schedule-inbox-URL xmlns:B="urn:ietf:params:xml:ns:caldav"/>
   <B:schedule-outbox-URL xmlns:B="urn:ietf:params:xml:ns:caldav"/>
   <A:supported-report-set/>
 </A:prop>
</A:propfind>

作为对上述 PROPFIND 请求的回复，我将响应设置如下：

响应标题

Accept-encoding  gzip, deflate
Accept  */*
Connection  keep-alive
Prefer  return=minimal
Host  192.168.0.12:8080
Brief  t
User-agent  Mac+OS+X/10.10.5 (14F27) CalendarAgent/316.1
Depth  0
Authorization  Basic YWRtaW46cGFzc3dvcmQ=
Accept-language  en-us
Content-type  text/xml
Content-length  743

                        "<B:schedule-outbox-URL xmlns='urn:ietf:params:xml:ns:caldav'><href xmlns='DAV:'>/calendars/__uids__/admin/outbox/</href></B:schedule-outbox-URL>"+

                    "</A:prop>" +
                    "<A:status>HTTP/1.1 200 OK</A:status>" +
                "</A:propstat>" +
            "</A:response>" +
        "</A:multistatus>";

在向客户端发送响应后，客户端再次发回相同的属性（不是全部 - 如下所示）。

<?xml version="1.0" encoding="UTF-8"?>
<A:propfind xmlns:A="DAV:">
  <A:prop>
    <A:current-user-principal/>
    <A:principal-collection-set/>
  </A:prop>
</A:propfind>

所以任何人都可以让我知道在设置这些属性时我在哪里出错了？

Answer 1

正如Evert在评论部分提到的，客户端有点健谈。经过几次观察，我发现了同样的情况。

即使在设置之后，WebDAV属性也会在请求中返回
