输出URL中的变量

Question

我想在URL中以变量的形式打印我自己的日期:

我有以下网址:

<cfset urladdress = "https://abc.xyz.com/start_date=2013-04-01&end_date=2014-04-22&data_type=123"> 

我已将日期设置如下:

<cfparam name="startdate" default="#DateFormat(dateAdd('d',-1,now()), 'yyyy-mm-dd')#">
<cfparam name="enddate" default="#DateFormat(dateAdd('d',0,now()), 'yyyy-mm-dd')#">

现在,我正在尝试打印它,如下所示:

<cfset urladdress = "https://abc.xyz.com/start_date="<cfoutput>#startdate#</cfoutput>"&end_date="<cfoutput>#enddate#</cfoutput>"&data_type=123">

我得到以下错误:

 Invalid CFML construct found on line 19 at column 123.
ColdFusion was looking at the following text:

<

The CFML compiler was processing:

    < marks the beginning of a ColdFusion tag.Did you mean LT or LTE?
    A cfset tag beginning on line 19, column 2.

我是否需要使用URLEncoded格式函数？

Answer 1

你不需要<cfoutput>在里面<cfset>

<cfset urladdress = 
  "https://abc.xyz.com/start_date=#startdate#&end_date=#enddate#&data_type=123">

你应该使用encodeForURL()(cf10 + only)或urlEncodedFormat()来保证变量的安全.

如果您想encodeForURL()在CF9中使用,请查看:https: //github.com/misterdai/cfbackport
