    DeSerializedJSON - how to make use of it?

    wearekonstruct

      I am running a cfhttp request as follows:

       

      <cfhttp url="http://www.thedata.place/dataset/323f337f-8d97-4e39-acf4-dbdb7a7a3fab/resource/911510a9-bd 85-409c-bcf4-f4b99a81b3b2/download/pcclibraries4326.geojson" >

        

      <!--- JSON data is sometimes distributed as a JavaScript function.

      The following REReplace functions strip the function wrapper. --->

      <cfset theData = REReplace(cfhttp.FileContent, "^\s*[[:word:]]*\s*\(\s*","")>

      <cfset theData = REReplace(theData, "\s*\)\s*$", "")>

       

      <cfset cfData = DeserializeJSON(theData)>

       

      <cfdump var="#theData#" >

       

      This results in:

      I have searched the internet on DeSerializeJSON() to try and make sense of the above but am getting nowhere. How would I turn it into a query or read it so that I can get the information out into a nice formatted way - or if all I wanted to do is get the coordinates out so I could plot a map - how would I do that - I am guessing it needs to be a query of sorts.

       

      All the answers I have found get me errors like "Complex structures" or "Runtime".

       

      Many thanks for helping in advance - this isn't the only one I have to try and make head or tail out of!! So advice also on how different types of structures like the above are read would be really useful.

          Hi, wearekonstruct,

           

          DeserializeJSON() can be used to turn a JSON object into a structure, array, or query object.  If the data originally was a query object and you used SerializeJSON() to create the JSON object, depending upon certain arguments used you can automatically revert the JSON object back into a query object.  Useful tool if you need to pass a lot of data via form or web service.

           

          If the JSON object was not originally a CF object, you can still make a structure or array or query from it, but you have to manipulate the string because CF formats JSON slightly differently.

           

          I don't have any sample code, at the moment, but I have (in the past) used Serialize/DeserializeJSON, and it can be quite useful.

           

          HTH,

           

          ^_^

           

          UPDATE: Let me clarify, a bit.  If the JSON string/object was originally a CF query, then you would use:

          <cfset cfData = DeserializeJSON(theData,false) />

           

          The 'false' argument for the useStrictMapping argument tells CF Server that if the original CF object converted to JSON was a query, make this a query.

           

          If the original object was _not_ a CF object, then you need to format the JSON string/object in such a way that CF can convert it to a CF object.

            Your data is complex. It has structure, but you have to tidy it up.

             

            Some points to take into account:

             

            1) { } represents a structure in ColdFusion. Example: {someKey="someValue"} instead of {"someKey":"someValue"}.

               Use regular expressions to replace all occurrences of '"someKey": ' with 'someKey= '.

               Example:

               <cfset testString = '{"key1":"value1","key2":"value2"}'>

               <cfset newTxt = testString.replaceAll('"(\b[a-zA-Z0-9]+\b)":', '$1=')>

                <cfoutput>#newTxt#</cfoutput>

            2) [ ] represents an array. Example: [1, "some words", someObject].

             

            3) The following may be troublesome in ColdFusion: "someKey"= null.

                Acceptable alternatives are: someKey= "" or someKey= "null".

             

            After you implement these suggestions you will get the following structure:

             

            <cfset theData= {

                                type= "FeatureCollection",
