使用ColdFusion和CFFeed的rss feed中的图像

Question

我有一个脚本，它生成一个带有ColdFusion及其CFFeed标记的xml文件。除了图像之外，它工作得很好。我知道你必须在CDATA中封装图像才能显示它。我不确定我的设置是否正确，因为图片没有显示在我的Google Reader / Feedly feed中。代码如下：

<cfquery datasource="data" name="queryT">
SELECT *
FROM qTable
WHERE ... 
ORDER BY...
</cfquery> 

<cfset RssStruct                = StructNew() />
<cfset RssStruct.link           = "https://www.url.com" />
<cfset RssStruct.title          = "sitename" />
<cfset RssStruct.description    = "url Blog" />
<cfset RssStruct.image.url      = 'https://www.url.com/assets/img/ns.png' />
<cfset RssStruct.image.title    = 'Site Name' />
<cfset RssStruct.image.link     = 'https://www.url.com' />
<cfset RssStruct.pubDate        = Now() />
<cfset RssStruct.version        = "rss_2.0" />
<cfset RssStruct.item           = ArrayNew(1) />
<cfset threadlist               = "">
<cfset index                    = 1>

<cfloop query="queryT">
    <cfif listcontains( threadlist , '#id#' ) eq 0>
        <cfset threadlist = ListAppend(threadlist, '#id#')>
             <!--- Here let's clean up and ensure that all values are XML Compliant --->
            <cfset RssStruct.item[index]                    = StructNew() />
            <cfset RssStruct.item[index].guid               = structNew() />
            <cfset RssStruct.item[index].guid.isPermaLink   ="YES" />
            <cfset RssStruct.item[index].guid.value         = 'https://www.url.com/page.cfm?itemid=#queryT.id#' />
            <cfset RssStruct.item[index].pubDate            = createDate(year(Posted), month(Posted), day(Posted)) />
            <cfset RssStruct.item[index].title              = xmlFormat(#title#) />
            <cfset RssStruct.item[index].Body               = xmlFormat(#Body#) />
            <cfset RssStruct.item[index].description        = StructNew() />
            <cfset RssStruct.item[index].description.value  = '<![CDATA[ <img src="https://www.url.com/assets/Photos/photo/#id#.jpg"> #body#  ]]>' />
            <cfset RssStruct.item[index].link               = 'https://www.url.com/page.cfm?item=#queryT.id#' /><br>
        <cfset index = index + 1>
    </cfif>
</cfloop>

<cffeed action="create" name="#RssStruct#" overwrite="true" xmlVar="myXML" outputFile = "Feed.xml"  />`

Answer 1

看起来您已经为item下的<description>元素创建了一个结构。您是否尝试过简单地将代码放入<description>中？

而不是这样：

        <cfset RssStruct.item[index].description        = StructNew() />
        <cfset RssStruct.item[index].description.value  = '<![CDATA[ <img src="https://www.url.com/assets/Photos/photo/#id#.jpg"> #body#  ]]>' />

试试这个：

        <cfset RssStruct.item[index].description  = '<![CDATA[ <img src="https://www.url.com/assets/Photos/photo/#id#.jpg"> #body#  ]]>' />

您是否尝试过改用项目的<enclosure>元素？

Definition and Usage

元素的作用是:允许将媒体文件包含在项目中。

属性

长度-必填。定义媒体文件的长度(字节)

类型-必填。定义媒体文件的类型

url -必填。定义媒体文件的URL

示例如下(您需要以字节为单位确定图像的大小)：

<enclosure url="https://www.url.com/assets/Photos/photo/#id#.jpg" length="#ImageLength#" type="image/jpeg" />
