Title: NetWebServiceMethod - change JSON reply type
Post by: Thys on April 19, 2017, 10:04:09 AM

Hi,

I have a string variable as a return value in a web service method that returns JSON. Under certain conditions I would like this value not to contain string quotes around it in the JSON result. I see that in the generated code when I change

jsonResults.append('content',p_web.AsciiToUtf(REG:content),json:String)

to

jsonResults.append('content',p_web.AsciiToUtf(REG:content),json:Literal)

the string quotes are not added. How can this be done without changing the generated code?

Thanks

An embed point per parameter after the append statement can definitely be helpful please...

I sense you have an OMIT statement in the gleam of your eye....

Incidentally json:literal would not be the right equate to use there, rather you'd want one of

json:String                   EQUATE(1) !json literal types
json:Numeric                  EQUATE(2)
json:Object                   EQUATE(3)
json:Array                    EQUATE(4)
json:Boolean                  EQUATE(5)
json:Nil                      EQUATE(6)
or a new one;
json:Auto                EQUATE(7)


the last one selects an appropriate type based on the contents of the value.

I've added a template setting to the "Field" and "StringTheory" types though for build 9.27 though.

cheers

Hi Bruce.

I installed 9.27 today. See attached - there is only one option in the "JSON type" drop list. Is that correct? If so, what purpose does the drop list have with only one option?

Bruce,

I also now get this prototype error - see attached.I saw that the last parameter is just "Auto", I changed the source to "json:auto" but it seems like the method override doesn't exist.

in Netweb.tpw
line circa 18686

replace the line
            #Prompt('JSON type',DROP('String,Numeric,Object,Array,Boolean,Null,Auto')),%MethodReturnJsonType,default('String')

with
            #Prompt('JSON type',DROP('String|Numeric|Object|Array|Boolean|Null|Auto')),%MethodReturnJsonType,default('String')

repeat for line 18691

sorry about that - fixed for the next build.

Bruce
