有没有办法在 ColdFusion 中转义磅字符 (#)？

Question

我在 CFC 文件中有一个函数，该函数将 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，属性之一具有字符 # 作为名称的一部分。该字符使代码在 ColdFusion 中中断，因为它被解释为变量。有什么方法可以让 ColdFusion “转义”该字符并认为它只是一个字符串？请记住，这是 JSON 字符串的一部分。

下面是我的功能。由于 JSON 字符串中的 # 字符，它不允许我访问 dnisObject。如果我从 JSON 字符串中删除那些 # 它工作正常。这些值必须使用# 存储在数据库中，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

与您通常逃避磅符号的方式相同：将它们加倍。来自documentation：

...要在字符串中包含 [井号]，请将字符加倍；为了 例如，使用## 表示单个# 字符。

由于输入是字符串，只需执行 Replace() 即可将单个井号替换为两个井号。

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}]'>

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