Question

如果已设置具有摘要授权的SabreDAV CalDAV服务器。通过iPhone，Outlook / CalDavSychronizer，Thunderbird / Lightning访问日历时，一切正常！

现在我试图通过php使用php_curl访问日历：

<?php

$url = "http://servername/calendars/user/calendar1/";
$username = "username";
$password = "password";
$calStart = gmdate("Ymd\THis\Z");
$calEnd = gmdate("Ymd\THis\Z", strtotime("+4 weeks"));


$postdata = '<C:calendar-query xmlns:C="urn:ietf:params:xml:ns:caldav">
   <D:prop xmlnx:D="DAV:">
   <C:calendar-data>
     <C:expand start="'.$calStart.'"
               end="'.$calEnd.'"/>
   </C:calendar-data>
 </D:prop>
 <C:filter>
   <C:comp-filter name="VCALENDAR">
     <C:comp-filter name="VEVENT">
       <C:time-range start="'.$calStart.'"
                     end="'.$calEnd.'"/>
     </C:comp-filter>
   </C:comp-filter>
 </C:filter>
</C:calendar-query>';


$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_PROTOCOLS, CURLPROTO_HTTP);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, 'REPORT');
curl_setopt($curl, CURLOPT_HTTPHEADER, array('Depth: 1', 'Content-Type: text/xml; charset=utf-8', 'Content-Length: '.strlen($postdata)));
curl_setopt($curl, CURLOPT_USERPWD , $username.':'.$password);
curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_DIGEST);
curl_setopt($curl, CURLOPT_POSTFIELDS, $postdata);


$raw_response = curl_exec($curl);
curl_close($curl);

echo "raw response: " . $raw_response;

?>

但答案总是如此：

<?xml version="1.0" encoding="utf-8"?>
<d:error xmlns:d="DAV:" xmlns:s="http://sabredav.org/ns">
  <s:sabredav-version>3.2.2</s:sabredav-version>
  <s:exception>ErrorException</s:exception>
  <s:message>XMLReader::XML(): Empty string supplied as input</s:message>
</d:error>

Apache访问日志：

知道问题出在哪里？感谢...

修改：

我想我已经把问题缩小了一点点。它处理摘要授权。预期的行为是：

Curl发送请求的标头。
响应是401，带有“WWW-Authenticate”和“Authorization”。
Curl使用正确的授权参数发送完整请求（包括正文）。

除了REPORT ...

之外，这适用于每个请求（GET，PROPFIND，...）

记录包括 REPORT 请求：

记录包括 PROPFIND 请求（最终400是正确的...如果已使用REPORT有效负载测试PROPFIND ......）：

对我来说这看起来像个错误。但是哪里？是卷曲还是SabreDAV？

在CalDAV（SabreDAV）服务器上通过php_curl回答请求500
