这是我获取 api 的代码

 $apiurl = "https://class.cvcngr.in/bigbluebutton/api/create?allowStartStopRecording=true&attendeePW=ap&autoStartRecording=false&meetingID=random-1495797&moderatorPW=mp&name=random-1495797&record=false&voiceBridge=74999&welcome=%3Cbr%3EWelcome+to+%3Cb%3E%25%25CONFNAME%25%25%3C%2Fb%3E%21&checksum=ad1f82091f78ee18673f9c5be36df9eef7860187";


  $ch = curl_init();
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_URL, $apiurl);
  $response = curl_exec($ch);
  curl_close($ch);   
  $xml = simplexml_load_string($response);
  echo $xml;

在上面，我使用了一个 apiurl 来存储 API 的 URL。这是我的自定义 API，服务提供商提供了一个测试 API

$apiurl2 "http://test-install.blindsidenetworks.com/bigbluebutton/api/create?allowStartStopRecording=true&attendeePW=ap&autoStartRecording=false&meetingID=random-9370670&moderatorPW=mp&name=random-9370670&record=false&voiceBridge=79891&welcome=%3Cbr%3EWelcome+to+%3Cb%3E%25%25CONFNAME%25%25%3C%2Fb%3E%21&checksum=0aae50d2d079fd67138a7b266837f6b0112166b5";

这两个 URL 给出了相同的响应，但我只有在使用 apiurl2 时才能获取数据。当我使用第一个时没有响应。但是当我直接在浏览器中使用时没有问题

它工作得很好，$xml变量是一个SimpleXMLElement实例。echo试图打印一个字符串。您可以使用对象运算符打印其所有内容var_dump($xml)并直接访问其元素：echo $xml->dialNumber甚至循环它们：

<?php

  $apiurl = "https://class.cvcngr.in/bigbluebutton/api/create?allowStartStopRecording=true&attendeePW=ap&autoStartRecording=false&meetingID=random-1495797&moderatorPW=mp&name=random-1495797&record=false&voiceBridge=74999&welcome=%3Cbr%3EWelcome+to+%3Cb%3E%25%25CONFNAME%25%25%3C%2Fb%3E%21&checksum=ad1f82091f78ee18673f9c5be36df9eef7860187";


  $ch = curl_init();

  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_URL, $apiurl);

  $response = curl_exec($ch);
  $xml      = simplexml_load_string($response);

  // var_dump($xml);
  // echo 'Dial number: ' . $xml->dialNumber;

  foreach ($xml as $key => $value) {
      echo "{$key}: {$value}\n";
  }

  curl_close($ch);
