Comment faire pour contourner SerializeJSON dans CF8 encodage caractères non imprimables?

Question

SerializeJSON crée un JSON avec des caractères non imprimables (par exemple, ASCII 21)

Ce JSON est invalide. Comment puis-je contourner cela.

Une regex supprimant les caractères non imprimables fonctionnerait-elle?

Quelle regex supprimerait les caractères non imprimables?

Eh bien, cette solution simple a été créée pour cffeed, mais votre problème est très similaire.

D'abord j'ai essayé d'utiliser la bibliothèque Java StringEscapeUtils (Commons Lang API), mais elle n'a pas échappé à mon contenu correctement. Bien qu'il soit recommandé pour XML. Donc, cette méthode cfc fonctionne pour moi. Peut-être vous aidera aussi.

<cffunction name="cleanXmlString" access="public" returntype="any" output="false" hint="Replace non-valid XML characters"> 
    <cfargument name="dirty" type="string" required="true" hint="Input string"> 
    <cfset var cleaned = "" /> 
    <cfset var patterns = "" /> 
    <cfset var replaces = "" /> 

    <cfset patterns = chr(8216) & "," & chr(8217) & "," & chr(8220) & "," & chr(8221) & "," & chr(8212) & "," & chr(8213) & "," & chr(8230) /> 
    <cfset patterns = patterns & "," & chr(1) & "," & chr(2) & "," & chr(3) & "," & chr(4) & "," & chr(5) & "," & chr(6) & "," & chr(7) & "," & chr(8) /> 
    <cfset patterns = patterns & "," & chr(14) & "," & chr(15) & "," & chr(16) & "," & chr(17) & "," & chr(18) & "," & chr(19) /> 
    <cfset patterns = patterns & "," & chr(20) & "," & chr(21) & "," & chr(22) & "," & chr(23) & "," & chr(24) & "," & chr(25) /> 
    <cfset patterns = patterns & "," & chr(26) & "," & chr(27) & "," & chr(28) & "," & chr(29) & "," & chr(30) & "," & chr(31) /> 

    <cfset replaces = replaces & "',',"","",--,--,..." /> 
    <cfset replaces = replaces & ",-, , , , , , , " /> 
    <cfset replaces = replaces & ", , , , , , " /> 
    <cfset replaces = replaces & ", , , , , , " /> 
    <cfset replaces = replaces & ", , , , , , " /> 

    <cfset cleaned = ReplaceList(arguments.dirty, patterns, replaces) /> 

    <cfreturn cleaned /> 

</cffunction>
