有没有办法让动态生成的二维码打印在徽章卡上？

问题描述 投票：0回答：1

自从 Google 停止使用图表 API 以来，我不得不更改我们多年来一直使用的二维码生成器。我在这里找到了一个新的https://goqr.me/api/doc/create-qr-code/。我的编程方式工作了一个月左右，但现在已经停止了。

我单独测试了生成器，通过将链接复制到浏览器中来确保它正常工作，并且它按预期工作。我认为问题出在调用生成器和将 QR 码添加到徽章卡以便可以打印之间；所以在 

<cfif>
块中。我尝试使用 
<img>
标签将其放在不同的位置，看看会发生什么。当我将其放在 
<cfhttp>
标签下时，生成的二维码显示在上方并与徽章卡分开，但是当我将该图像标签放在 if 块内时，二维码不再显示在任何地方。

任何帮助将不胜感激，我提前感谢您。

这是制作徽章卡的输出部分。

coldfusion qr-code

您的ColdFusion代码没有任何问题。它可以很好地获取二维码。

<cfset qrCodeURL = "https://www.ohrc.org/binkley/badgeCard/PDFs/">
<cfset apiURL = "https://api.qrserver.com/v1/create-qr-code/?size=150x150&data=">
<cfhttp method="get" url="#apiURL##qrCodeURL#" getasbinary="yes">
<cfoutput>
<img
    src="data:#cfhttp.mimetype#;base64,#toBase64( cfhttp.fileContent )#"
    height="150" width="150"
    >
</cfoutput>

如果您只是在屏幕上显示二维码图像，那么您甚至不需要使用 

cfhttp
来获取图像。

<cfoutput>
<img
    src="https://api.qrserver.com/v1/create-qr-code/?size=150x150&data=https://www.ohrc.org/binkley/badgeCard/PDFs/#Replace(badgPhotoName, '.jpg', '.pdf', 'All')#"
    height="150" width="150"
    >
</cfoutput>

可运行代码： https://cffiddle.org/app/file?filepath=d7e9b6f1-31e6-4256-9410-1b776a724588/43e40a67-d103-4644-a826-f6287cd32acc/39c595f2-e4e5-4f00-a912-acef37e2706 .cfm

你说“我的编程方式工作了一个月左右，但现在已经停止了。”它真的在没有任何代码更改的情况下停止工作吗？

您发布了很多代码，其中包括不相关的内容（例如数据库查询），因此很难找出问题所在，但我怀疑您的 JavaScript 中有 ColdFusion 代码。例如这些行：

'</span>'+
'<cfif session.trackdatadeletepicsuserlist Contains SESSION.Auth.UserLogin>'+
  '<a href="tstDeleteBadgeCard.cfm?Photo=#BadgeCards.filename#&id=#BadgeCards.id#&tdLicenseID=#Form.tdLicenseID#">'+
    ' <img src="../delete.gif" border="0" alt="x" height="8" width="8" name="Delete" title="Delete This Photo">'+
  '</a>'+
'</cfif>'+

ColdFusion 代码在服务器上运行和评估。然后 HTML 返回到运行 JavaScript 代码的浏览器。如果您查看页面的源代码，您可能会发现问题所在。浏览器中的控制台也可能为您提供一些线索。
