从 WordPress REST API JSON 响应中提取图像 url
Extract Image url from WordPress REST API JSON response
我是 WordPress REST 的新手 API，我不知道如何从 API (https://www.example.com/wp-json/wp/v2/posts) 响应的“content”键中提取图像 URL看起来像这样：
"content": {
"rendered": "\n<p>From munching on a casual pizza to romantic candlelit dinner in Kolkata with your better half, Valentine’s week is filled with all of these!</p>\n\n\n\n<p>The love week of February offers the perfect excuse to sample Kolkata’s very best restaurants with your other half.</p>\n\n\n\n<p>Find your dream date night in our Valentine’s Day special guide to the cutest restaurants in Kolkata.</p>\n\n\n\n<h2><i><center>Blue and Beyond</center></i></h2>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter\"><img src=\"https://kolkatasutra.com/wp-content/uploads/2021/02/blue-n-beyond.png\" alt=\"\" class=\"wp-image-919\" srcset=\"https://kolkatasutra.com/wp-content/uploads/2021/02/blue-n-beyond.png 540w, https://kolkatasutra.com/wp-content/uploads/2021/02/blue-n-beyond-300x197.png 300w, https://kolkatasutra.com/wp-content/uploads/2021/02/blue-n-beyond-150x99.png 150w\" sizes=\"(max-width: 540px) 100vw, 540px\" /><figcaption>Blue & Beyond, New Market</figcaption></figure></div>\n\n\n\n<p>Situated in the New Market area, this place boasts of beautiful rooftop open-air seating. It also has an indoor seating</p>\n\n\n\n<p>You can expect a feel of colonial Kolkata with Stuart Hogg Market below."
}
- 我尝试了 this 解决方案，但在我的情况下“featured_media”为 0。
- 已安装 this 插件，但字段“better_featured_image”在所有帖子中显示为空。
是可能解决问题的唯一解决方案，但我不知道如何使用正则表达式提取图像 URL。
请帮助我使用 Regex 提取 URL。或者如果有其他方法可能有帮助，请在回答中提及。
您可以使用 json_decode() 函数解码 json 字符串。然后你可以 preg_match 匹配 '/src="([^"]*)"/' 正则表达式来提取你的 src。检查下面的代码。
<?php
