How can I prevent SerializeJSON from changing Yes/No/True/False strings to boolean?

Question

I have a data struct being stored in JSON format, converted using the serializeJSON function. The problem I am running into is that strings that can be boolean in CF such as Yes,No,True,and False are converted into JSON as boolean values. Below is example code. Any ideas on how to prevent this?

Code:

<cfset test = {str='Yes'}>
<cfset json = serializeJSON(test)>
<cfset fromJSON = deserializeJSON(json)>

<cfoutput>
    #test.str#<br>
    #json#<br>
    #fromJSON.str#
</cfoutput>

Result:

Yes
{"STR":true}
YES

Answer 1

I believe that your or any similar "string forcing" workaround is the only possible way to prevent such behavior in Adobe CF for now.

BTW, Railo works as expected with your example. Here is the output:

Yes
{"STR":"Yes"}
Yes

It is also works same way for the numbers with trailing zeros.

Append a space to the end. It sounds weird but it works.

<cfset test = {str='Yes }>
<cfset json = serializeJSON(test)>
<cfset fromJSON = deserializeJSON(json)>

Answer 3

I'd try javacasting it: key = javacast("string", "yes"). That should force CF to recognize it as a string rather than as a boolean.

Thanks- Prefixing with space is an easy solution and it worked.
