问题 I was looking at the cfhttp tag and it is possible to use it to pass variables via clicked link? <cfhttp method="Post" url="myurl"> I am trying to pass variables on a link click (for example, user IDs), but it seems a bit insecure to send via GET... 回答1: My original answer completely missed the mark, but I can't delete an accepted answer, so for the purposes of clarity, I'm changing this answer to agree with Billy's comment above. CFHTTP is for making a server-side request to another website

问题 I'm exporting from ColdFusion 9 to Excel and I want to set the page orientation and scaling so the exported excel document fits to page and prints landscape. How to accomplish this? Edit with solution: Thanks for the assistance. The page-orientation setting worked as advertised. I used the following hack to get it to fit to page width. This page contains documentation on the various settings that are possible: http://msdn.microsoft.com/en-us/library/Aa155477%28office.10%29.aspx <cfheader name

问题 I am having difficulty working with complex arrays and could use some help. I am working with the EWS API to integrate mail functions with Exchange 2010 and CF. The code below connects to a mailbox that the primary account has delegated authority to. I want to return a list of messages in the inbox and work with the values that EWS returns (subject line, body, from, to, etc). I have not worked with complex arrays like this before, so I'm confused about how to reference the values returned,

问题 I have the following date string: 2017-05-02 08:00:00.0 When I apply datetimeformat() like: #datetimeformat(item.getValue('releasedate'), 'h:mm a')# It is rounding up by 5 minutes and outputting: 8:05 AM. In the code above, 'releasedate' is the string that is being passed in. How do I fix this? 回答1: Nobody is rounding anything. You are outputting the month here instead of the minutes, and the month happens to be May, so that is 05 with leading zero. https://cfdocs.org/datetimeformat: mm :

问题 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 =

问题 I have a simple Form , which on submission sets a variable in SESSION like <cfset SESSION.shownote = 1> After firing an confirmation Email to the user , I am just deleting this variable from the Session. <cfset structdelete(SESSION,"shownote")> Do I really need to user cflock in this case ? I can not think of a Race condition here. As SESSION varies from one user to another , Can anyone please suggest me exactly on which situation we should use cflock with session variables? I have also heard

问题 I can pull data via <cfquery name="keyTypeGroup"> SELECT DISTINCT keyTypeGroup FROM data.keyType </cfquery> I can pull all the data via orm ... return EntityLoad("data_KeyType"); ... I have tied <cfdump var="#ORMExecuteQuery('SELECT DISTINCT KeyGroupType FROM data.KeyType', true)#"> But I get Error while executing the Hibernate query. org.hibernate.hql.ast.QuerySyntaxException: data.KeyType is not mapped [SELECT DISTINCT KeyGroupType FROM data.KeyType] How should I approach fixing this? 回答1:

问题 I am trying to take an existing ColdFusion website that currently uses Authorize to process cards. I would like to switch over the payment gateway and use Square. Does anyone have any sample ColdFusion code on how to use the Square API as a payment gateway? 回答1: Here is a gist another developer has used <cfset IDKey = CreateUUID()> <cfset request.params.card_nonce = form.nonce> <cfset request.params.amount_money.amount = 100> <cfset request.params.amount_money.currency = 'USD'> <cfset request

问题 In my ColdFusion application, I want to keep the images outside of wwwroot in this folder: C:\extSite\stdImages I created a mapping in wwwroot\WEB-INF\jrun-web.xml like this: <virtual-mapping> <resource-path>/extStdImages</resource-path> <system-path>C:\extSite\stdImages\</system-path> </virtual-mapping> To display an image, I do this: <img src="/extStdImages/abc.jpg"> This works fine on my dev site (which is using ColdFusion's built-in web server), but the image does not display in

问题 My error report told me that an error has occurred when an user tried uploading an empty file to my server (don't ask why the user did that - I don't know) and now I want to catch that exception which said " No data was received in the uploaded file ". I wonder if there is a better way than putting a <CFTRY> around the <CFFILE action="upload"> like this: <CFTRY> <CFFILE action="upload" destination="#expandpath("upload")#" filefield="form.file" nameconflict="makeunique" /> <CFCATCH> <!---
