Question

我试图通过卷曲从某个CalDAV服务器（在这种情况下是贝加尔）获取所有事件。该任务的基础教程是this。

根据本教程，请求应如下所示：

PROPFIND /calendars/johndoe/home/ HTTP/1.1
Depth: 0
Prefer: return-minimal
Content-Type: application/xml; charset=utf-8

<d:propfind xmlns:d="DAV:" xmlns:cs="http://calendarserver.org/ns/">
  <d:prop>
     <d:displayname />
     <cs:getctag />
  </d:prop>
</d:propfind>

这是我的实施：

$headers = array(

        'Content-Type: application/xml; charset=utf-8',
        'Depth: 0',
        'Prefer: return-minimal'
    );

$fp = fopen(dirname(__FILE__).'/getEventCURLError.txt', 'w');
$url = "http://xxx.ch/dav/cal.php/calendars/john/john-cal/";
$userpwd = "john:12345";

// prepare request body
$doc  = new DOMDocument('1.0', 'utf-8');
$doc->formatOutput = true;

$query = $doc->createElement('c:calendar-query');
$query->setAttributeNS('http://www.w3.org/2000/xmlns/', 'xmlns:c', 'urn:ietf:params:xml:ns:caldav');
$query->setAttributeNS('http://www.w3.org/2000/xmlns/', 'xmlns:d', 'DAV:');

$prop = $doc->createElement('d:prop');
$prop->appendChild($doc->createElement('d:getetag'));
$prop->appendChild($doc->createElement('c:calendar-data'));
$query->appendChild($prop);
$doc->appendChild($query);
$body = $doc->saveXML();

echo "Body: " . $body . "<br>";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERPWD, $userpwd);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_STDERR, $fp);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PROPFIND');
curl_setopt($ch, CURLOPT_POSTFIELDS, $body);

$response = curl_exec($ch);
curl_close($ch);

print_r($response);    

$xml = simplexml_load_string($response);
print_r($xml)

输出是这样的：

Body: 

/dav/cal.php/calendars/john/john-cal/HTTP/1.1 200 OK 

SimpleXMLElement Object ( )

即使我在日历中有很多活动，但它们似乎并没有被退回。我在这做错了什么？任何意见都表示赞赏。

Answer 1

大概你的代码不起作用，因为你正在使用带有PROPFIND请求的日历查询REPORT实体。

$query = $doc->createElement('c:calendar-query');

...

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PROPFIND');

PROPFIND请求期望请求中的propfind实体，而不是日历查询实体，如原始示例所示：

PROPFIND /calendars/johndoe/home/ HTTP/1.1
Depth: 0
Prefer: return-minimal
Content-Type: application/xml; charset=utf-8

<d:propfind xmlns:d="DAV:" xmlns:cs="http://calendarserver.org/ns/">
  <d:prop>
     <d:displayname />
     <cs:getctag />
  </d:prop>
</d:propfind>

您有两种选择，要么创建正确的日历查询REPORT（即执行curl_setopt（$ ch，CURLOPT_CUSTOMREQUEST，＆＃39; REPORT＆＃39;）），要么发出正确的PROPFIND请求实体。我说后者是更好的选择。

此请求不适用于从caldav获取事件。它用于检索日历信息，即calendarName，calendarId等。请参阅https://tools.ietf.org/html/rfc4791#section-7.8.1以查找事件

Method-: REPORT
Content type-: application/xml; charset=utf-8
Header -: Depth : 1
URL-:GET /<ICLOUD_USER_ID>/calendars/
