我是 PHP 新手,正在尝试使用第三方代码,即 Big blue button api https://github.com/bigbluebutton/bigbluebutton/tree/master/labs/bbb-api-php

我尝试调用BigBlueButton->createMeeting()如下所示的函数:

public function createMeeting($createMeetingParams, $xml = '')
{
    $xml = $this->processXmlResponse($this
        ->getCreateMeetingURL($createMeetingParams), $xml);
    //$xml is fine
    return new CreateMeetingResponse($xml);
}

创建会议响应类

  namespace BigBlueButton\Responses;

/**
 * Class CreateMeetingResponse
 * @package BigBlueButton\Responses
 */
class CreateMeetingResponse extends BaseResponse
{
    /**
     * @return string
     */
    public function getMeetingId()
    {
        return $this->rawXml->meetingID->__toString();
    }

    /**
     * @return string
     */
    public function getAttendeePassword()
    {
        return $this->rawXml->attendeePW->__toString();
    }

    /**
     * @return string
     */
    public function getModeratorPassword()
    {
        return $this->rawXml->moderatorPW->__toString();
    }

    /**
     * Creation timestamp.
     *
     * @return double
     */
    public function getCreationTime()
    {
        return doubleval($this->rawXml->createTime);
    }

    /**
     * @return int
     */
    public function getVoiceBridge()
    {
        return intval($this->rawXml->voiceBridge);
    }

    /**
     * @return string
     */
    public function getDialNumber()
    {
        return $this->rawXml->dialNumber->__toString();
    }

    /**
     * Creation date at the format "Sun Jan 17 18:20:07 EST 2016".
     *
     * @return string
     */
    public function getCreationDate()
    {
        return $this->rawXml->createDate->__toString();
    }

    /**
     * @return true
     */
    public function hasUserJoined()
    {
        return $this->rawXml->hasUserJoined->__toString() == 'true';
    }

    /**
     * @return int
     */
    public function getDuration()
    {
        return intval($this->rawXml->duration);
    }

    /**
     * @return bool
     */
    public function hasBeenForciblyEnded()
    {
        return $this->rawXml->hasBeenForciblyEnded->__toString() == 'true';
    }

    /**
     * @return string
     */
    public function getMessageKey()
    {
        return $this->rawXml->messageKey->__toString();
    }

    /**
     * @return string
     */
    public function getMessage()
    {
        $this->rawXml->message->__toString();
    }
}

BaseResponse 类

namespace BigBlueButton\Parameters;

/**
 * Class BaseParameters.
 */
abstract class BaseParameters
{
    /**
     * @param $array
     *
     * @return string
     */
    protected function buildHTTPQuery($array)
    {
        return http_build_query(array_filter($array));
    }

    /**
     * @return string
     */
    abstract public function getHTTPQuery();
}

现在,当我调用该BigBlueButton->createMeeting()函数时,我期待一个可以编码为 json 的对象,但我得到的是这个(我在print_r()这里使用过..):

BigBlueButton\Responses\CreateMeetingResponse Object
(
    [rawXml:protected] => SimpleXMLElement Object
        (
            [returncode] => FAILED
            [messageKey] => idNotUnique
            [message] => A meeting already exists with that meeting ID.  Please use a different meeting ID.
        )

)

我不确定发生了什么,但我认为前缀命名空间' BigBlueButton\Responses\CreateMeetingResponse Object'是问题所在。我想解析我在 php 中得到的 json 对象的响应,但不能

这是我尝试解析它的地方

function easymeet_create_meeting($id) {
  // Create BBB object
  $bbb = new BigBlueButton\BigBlueButton();

  //creating meeting parameter
  $meetingParas=new BigBlueButton\Parameters\CreateMeetingParameters('123456','sned');

  //Creatign meeting
  return json_encode($bbb->createMeeting($meetingParas)); 
   ///print_r($bbb->createMeeting($meetingParas)) give the xml response shown above

}

返回部分看起来不错。你得到的错误来自BigBlueButton->createMeeting()

您已经使用您使用的 ID 创建了一个会议。您是否在创建新会议时生成新的会议 ID 以与 XML 一起传递?

编辑:

为了能够对响应进行 json_encode,您需要使用该getRawXml()函数,因为$rawXml它是基类的受保护属性,而类的其余部分只是方法。所以:

public function createMeeting($createMeetingParams, $xml = '')
{
    $xml = $this->processXmlResponse($this
        ->getCreateMeetingURL($createMeetingParams), $xml);
    //$xml is fine
    $resp = new CreateMeetingResponse($xml);
    return $resp->getRawXml();
}

应该只返回SimpleXMLElement您可以使用的 json_encode。
