从当前文档生成pdf [英] Generate pdf from current document

问题描述

我需要一种方法来从当前打开的coldfusion文档动态生成pdf。但我不知道如何处理这个，因为我没有找到一个方法ie，传递当前（html）文本到一个函数，通过使用cfdocument标签生成pdf。

I need a way to dynamicly generate a pdf from the currently opened coldfusion document. But I don't have an idea how to handle this because I didn't find a way i.e. to pass the current (html) text to a function which generates the pdf by using the cfdocument tag.

任何提示或想法，如何解决这个问题？

Any hints or ideas, how to solve this problem?

推荐答案

，您可以使用cfdocument的src属性通过内部自引用请求请求当前页面。Application.cfc中

Rather than capture the current response body, you could use the "src" attribute of cfdocument to request the current page via an internal self-referencing request.

：

<cffunction name="onRequestStart">

  <cfif IsDefined("url.showAsPDF") AND 
        url.showAsPDF IS "true" AND 
        cgi.http_user_agent IS NOT "ColdFusion">

    <cfset myURL = 
        "http" & 
         (IsDefined('CGI.HTTPS') AND CGI.HTTPS IS "On") ? "s" :  "") &
         "://#cgi.server_name#:#cgi.SERVER_PORT##cgi.script_name#?#cgi.query_string#">

    <cfdocument src="#myURL#" format="PDF"></cfdocument><cfabort>

  </cfif>
</cffunction>

这将查找名为showAsPDF的URL参数的存在。当定义并设置为true时，此代码将接管并在内部运行相同的请求，通过调用cfdocument进行路由。然后将响应作为PDF文档输出。

This will look for the presence of a URL parameter named "showAsPDF". When it is defined and set to "true", then this code will take over and run the same request internally, routed through a call to cfdocument. The response will then be output as a PDF document.
