php - 使用 SimpleXML 和 PHP 通过 https 获取 XML 内容的问题

Question

可能重复：
如何启用 HTTPS 流包装器

我正在使用简单的 XML 从 API 获取内容。通常我没有问题，但现在 URL 是 HTTPS，它似乎不起作用。有没有办法解决？

示例 XML（网址）：

<?xml version="1.0"?>
<calendars>
  <calendar accommodation_id="1049165">
    <day date="2012-08-09" vacancy="false" minimum_nights="7" arrival_day="true"/>
    <day date="2012-08-10" vacancy="false" minimum_nights="3" arrival_day="true"/>
    <day date="2012-08-11" vacancy="false" minimum_nights="3" arrival_day="true"/>
    <!-- ... -->
    <day date="2014-01-31" vacancy="true" minimum_nights="3" arrival_day="true"/>
  </calendar>
</calendars>

示例代码：

$xml2 = file_get_contents('');
$availability = new SimpleXMLElement($xml2);

Answer 1

You are using the XML API of the www.casapilot.com website.

The API is via HTTPS, one example URI is:

https://www.casapilot.com/api/1/accommodations/calendar.xml?auth_token=hyXHjP8QdrRuX8q3FsbC&id=1049165

For HTTPs to work, PHP needs the openssl extension. The information is given on the related Stream Wrapper Page:

Note: HTTPS is only supported when the openssl extension is enabled.

The openssl extension is then used for all HTTPS "files" transparently with the stream-wrapper for all URIs starting with https://.
