[英]Retrieving events from Google Calendar
我正在尝试检索Google日历的XML数据。 身份验证和检索都可行。 但是,当我检索事件时,gd:data不会作为协议参考文档包含在内( http://code.google.com/apis/calendar/data/2.0/developers_guide_protocol.html#RetrievingWithoutQuery )
我正在遇到的一些错误消息取决于我如何引用属性为“startTime”的“when”节点(我在这个轶事中的最终目标)如下:
致命错误:当它看起来像'startTime'=> (string) $cal->when->attributes()->startTime,
时,在第226行的... / googlecalendarwrapper.php中的非对象上调用成员函数attributes() 'startTime'=> (string) $cal->when->attributes()->startTime,
GoogleCalendarWrapper_Model :: getEventsList()[googlecalendarwrapper-model.geteventslist]:当节点看起来像'startTime'=> strval($cal->when->attributes()->startTime),
节点不再存在'startTime'=> strval($cal->when->attributes()->startTime),
strval()[function.strval]:当节点看起来像'startTime'=> strval($cal->when->attributes()),
'startTime'=> strval($cal->when->attributes('startTime')),
'startTime'=> strval($cal->when->attributes()),
节点不再存在'startTime'=> strval($cal->when->attributes('startTime')),
代码如下:
$xml = new SimpleXMLElement($this->get($url, $header));
$calendars = array();
foreach ($xml->entry as $cal){
$calendars[] = array(
'id'=>strval($cal->id),
'published'=>strval($cal->published),
'updated'=>strval($cal->updated),
'title'=>strval($cal->title),
'content'=>strval($cal->content),
'link'=>strval($cal->link->attributes()->href),
'authorName'=>strval($cal->author->name),
'authorEmail'=>strval($cal->author->email),
'startTime'=> strval($cal->when->attributes()),
);
}
XML:

根据这篇文章: http : //www.sitepoint.com/blogs/2005/10/20/simplexml-and-namespaces/您必须使用SimpleXMLElement以不同方式处理名称空间。 解决方案如下:
$xml = new SimpleXMLElement($this->get($url, $header));
$xml->asXML();
$calendars = array();
foreach ($xml->entry as $cal){
$ns_gd = $cal->children('http://schemas.google.com/g/2005');
$calendars[] = array(
'id'=>strval($cal->id),
'published'=>strval($cal->published),
'updated'=>strval($cal->updated),
'title'=>strval($cal->title),
'content'=>strval($cal->content),
'link'=>strval($cal->link->attributes()->href),
'authorName'=>strval($cal->author->name),
'authorEmail'=>strval($cal->author->email),
'startTime'=> strval($ns_gd->when->attributes()->startTime),
);
}
注意$ns_gd = $cal->children('http://schemas.google.com/g/2005');
- 这定义了命名空间。 然后从那里, $ns_gd->when->attributes()->startTime
从gd获取属性:当命名为startTime时。
男人,这是一个血腥的2天。 但我明白了。 希望这可以帮助有人在路上。
