在php中通过multiget REPORT方法获取日历数据 [英] Getting calendar-data via multiget REPORT method in php

问题描述

我尝试使用multiget请求在caldav中获取多个事件，如下所示：

I try to get multiple event in caldav using a multiget request as explain here: http://sabre.io/dav/building-a-caldav-client

或此处：
使用PHP / CalDAV回传Apple / iCloud日历数据

假设要像传递一样简单：

It's suppose to be as simple as passing:

<?xml version="1.0" encoding="UTF-8"?>
<B:calendar-multiget xmlns:B="urn:ietf:params:xml:ns:caldav">  
  <A:prop xmlns:A="DAV:">        
  <B:calendar-data/>
  </A:prop>
  <A:href xmlns:A="DAV:">/calendars/__uids__/DE6BFE56-B3DC-4C60-A9C7-ED05A45AAC92/calendar/00ECD3D1-72D0-4F56-9011-71A6180F848C.ics</A:href>
</B:calendar-multiget>

我使用PHP传递XML请求。
但是XML响应没有任何日历数据：

I'm using PHP to pass the XML request. But the XML response don't have any calendar-data:

SimpleXMLElement Object
(
    [response] => SimpleXMLElement Object
        (
            [href] => /calendars/__uids__/DE6BFE56-B3DC-4C60-A9C7-ED05A45AAC92/calendar/00ECD3D1-72D0-4F56-9011-71A6180F848C.ics
            [propstat] => SimpleXMLElement Object
                (
                    [prop] => SimpleXMLElement Object
                        (
                            [calendar-data] => SimpleXMLElement Object
                                (
                                )

                        )

                    [status] => HTTP/1.1 200 OK
                )

        )

)

我使用simplexml_load_string和print_r显示结果。
如何获取日历数据？

I use simplexml_load_string and print_r to display the result. How can I get the calendar-data?

GET方法工作正常，但是当我不更新> 50个事件时太慢了。

GET method work fine but is too slow when I wan't to update >50 events.

EDIT：
我可以使用hnh建议的终端中的Curl工作。但它不工作使用curl在PHP。这里是我使用的代码（url元素，日志，通过，XML请求是一样的终端使用）：

I can make it work using Curl in Terminal as suggested by hnh. But it doesn't work using curl in php. Here is the code I use (url element, log, pass, xml request are the same as the one use in terminal):

$xml= '<C:calendar-multiget xmlns="DAV:" xmlns:C="urn:ietf:params:xml:ns:caldav"><prop><C:calendar-data/></prop><href>/calendars/__uids__/DE6BFE56-B3DC-4C60-A9C7-ED05A45AAC92/calendar/94DA9025-02E5-4313-BF81-66641BC5989F.ics</href><href>/calendars/__uids__/DE6BFE56-B3DC-4C60-A9C7-ED05A45AAC92/calendar/175CA348-8877-4CDF-B19D-4C66E191F4B4.ics</href></C:calendar-multiget>';

$user = "MyLogin";
$pw= "MyPsw";
$url = "https://localhost:443/calendars/__uids__/DE6BFE56-B3DC-4C60-A9C7-ED05A45AAC92/calendar/";

$data = doRequest($user, $pw, $url, $xml);
print "<pre>";
print_r($data);
print "</pre>";

function doRequest($user, $pw, $url, $xml)
    {
        $c=curl_init($url);
        curl_setopt($c, CURLOPT_HTTPHEADER, array("Depth: 1", "Content-Type: text/xml; charset='UTF-8'", "User-Agent: DAVKit/4.0.1 (730); CalendarStore/4.0.1 (973); iCal/4.0.1 (1374); Mac OS X/10.6.2 (10C540)"));
        curl_setopt($c, CURLOPT_HEADER, 0);
        curl_setopt($c, CURLOPT_SSL_VERIFYHOST, 0);
        curl_setopt($c, CURLOPT_SSL_VERIFYPEER, 0);
        curl_setopt($c, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
        curl_setopt($c, CURLOPT_USERPWD, $user.":".$pw);
        curl_setopt($c, CURLOPT_CUSTOMREQUEST, "REPORT");
        curl_setopt($c, CURLOPT_POSTFIELDS, $xml);
        curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
        $data=curl_exec($c);
        curl_close($c);

        return $data;
    }

不返回任何日历数据：

/calendars/__uids__/DE6BFE56-B3DC-4C60-A9C7-ED05A45AAC92/calendar/175CA348-8877-4CDF-B19D-4C66E191F4B4.ics

  HTTP/1.1 200 OK

/calendars/__uids__/DE6BFE56-B3DC-4C60-A9C7-ED05A45AAC92/calendar/94DA9025-02E5-4313-BF81-66641BC5989F.ics

  HTTP/1.1 200 OK

推荐答案

返回数据。
问题是数据显示。由于日历数据以CDATA形式返回，您必须使用LIBXML_NOCDATA来显示它：

Actually, Curl request return the data. The problem is the data display. As the calendar data is return as CDATA, you have to use LIBXML_NOCDATA to display it:

simplexml_load_string($data, 'SimpleXMLElement', LIBXML_NOCDATA)
