application/ld+json中有图片显示图片没有图片显示空，并且还是绝对路径显示，代码如下：

<script type="application/ld+json">
	{
		"@context": "https://ziyuan.baidu.com/contexts/cambrian.jsonld",
		"@id": "https://ipkd.cn{dede:field name='arcurl'/}",
		"title": "{dede:field.title/}",
		"images": ["{dede:field.litpic runphp="yes"}if(@me == '/images/pic.png')@me = "";else @me = "https://ipkd.cn'@me'";{/dede:field.litpic}"],
		"description": "{dede:field.description/}",
		"pubDate": "{dede:field name='senddate' function='strftime("%Y-%m-%dT%H:%M:%S","@me")' /}"
	}
</script>
