Question

我在CFC文件中有一个函数，它接受一个JSON字符串作为参数。然后，该函数使用反序列化的数据来执行UPDATE查询。在JSON字符串中，其中一个属性具有字符#作为名称的一部分。此字符使代码在ColdFusion中中断，因为它被解释为变量。有没有办法让ColdFusion＆＃34;逃避＆＃34;那个角色并认为它只是一个字符串？请记住，它是JSON字符串的一部分。

以下是我的功能。由于JSON字符串中的dnisObject字符，它不允许我访问#。如果我从JSON字符串中删除那些#，它可以正常工作。这些值必须存储在#的数据库中，所以我不能完全删除它们。

<cffunction name="updateDnisHproduct" access="remote">
    <cfargument name = "lid" type = "numeric" required = "yes">
    <cfargument name = "updatedObj" type = "string" required="yes">


    <cfset dnisObject = DESERIALIZEJSON(arguments.updatedObj)/>

    <cfset test =[{"phone":"1001106672","lineType":"Outbound","label1":"Voicemail for line #54940","label4":"test","hcat":"18","freshStart":"0","phoneCode":"","hproduct":"3","checked":false},{"phone":"1001106672","lineType":"Outbound","label1":"Voicemail Line Box #58940","label4":"12","hcat":"54","freshStart":"0","phoneCode":"","hproduct":"12","checked":false}'>

    <cfset dnisObject = DESERIALIZEJSON(test)/>
</cffunction>

Answer 1

你通常会逃脱英镑标志：加倍。来自documentation：

...要在字符串中包含[井号]，请将该字符加倍;对于例如，使用##表示单个#字符。

由于输入是一个字符串，只需用Replace()代替一个带有两个磅符号的单个符号。

Answer 2

 <cfset test = '[{"phone":"1001106672","lineType":"Outbound","label1":"Voicemail Line For Call Box #54940","label4":"test","hcats":"18","freshStart":"0","phoneCode":"","hproduct":"3","checked":false},{"phone":"1001106672","lineType":"Outbound","label1":"Voicemail Line For Call Box #54940","label4":"test","hcats":"54","freshStart":"0","phoneCode":"","hproduct":"--","checked":false}]'>

 <!--- Escaping # sign using replace function so it doesn't get confused with the variable sign in 
ColdFusionldFusion --->

<cfset test = Replace(test, "#", "##" "all")
<cfset dnisObject = DESERIALIZEJSON(test)/>
<cfdump var="#dnisObject#">

有没有办法逃避ColdFusion中的英镑字符（＃）？
