rss中的图像使用ColdFusion和CFFeed [英] Images in rss feed using ColdFusion and CFFeed

问题描述

我有一个脚本生成一个xml文件与ColdFusion及其 CFFeed 标签。它工作相当不错，除了图像。我知道你必须使用封装在 CDATA 中的图像以显示它。我不确定是否已正确设置，因为图片未显示在我的Google阅读器/ Feedly Feed中。以下是代码：

 < cfquery datasource =dataname =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＃'）> 
<！---这里让我们清理，并确保所有的值都是XML兼容---> 
< 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> 
 
<！---生成Feed并将其保存到文件和变量。 ---> 
 
< cffeed action =createname =＃RssStruct＃overwrite =truexmlVar =myXMLoutputFile =Feed.xml/>`
  




解决方案

看起来你已经为 ; description> 元素。您尝试过简单地将代码放在< description> 中吗？

>

 < 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＃]]>'/> 
  

尝试：

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

您是否尝试过使用< enclosure>

$ b

b $ b

length - 必需。定义媒体文件的长度（以字节为单位）

type - 必需。定义媒体文件的类型

url - 必需。定义媒体文件的URL

一个例子是这样的（你需要确定图像的大小， ：

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

I have a script that generates an xml file with ColdFusion and its CFFeed tag. It works pretty good except for images. I understand that you have to use encapsulate the image in CDATA in order to display it. I am not sure if I have set it up correctly because the images are not showing up in my Google Reader / Feedly feed. Here is the code:

<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>

<!--- Generate the feed and save it to a file and variable. --->

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

解决方案

It looks like you have created a structure for the <description> element under the item. Have you tried simply putting your code in the <description> instead?

Instead of this:

        <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#  ]]>' />

Try this:

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

Have you tried using the <enclosure> element of the item instead?

Definition and Usage

The element allows a media-file to be included with an item.

Attributes

length - Required. Defines the length (in bytes) of the media file

type - Required. Defines the type of media file

url - Required. Defines the URL to the media file

An example would be something like (you will need to determine the size of the image in bytes):

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