B4J Question Can Escaping be disabled in JSONGenerator ?

aminoacid · Apr 6, 2020

I have looked all over to find a way to disable the "escaping" of the slash "/" in a JSON string created by the JSONGenerator but I am at a loss at this point without a solution. For example in this very simple code fragment:

B4X:

  Dim Map1 As Map
    Map1.Initialize
    
    Map1.Put("AdminFolder","root/users/admin")
    
    Dim JSONGenerator As JSONGenerator
    JSONGenerator.Initialize(Map1)
    Log(JSONGenerator.ToPrettyString(2))

The Log produces:

{ "AdminFolder": "root\/users\/admin" }

What I would like to get is:

{ "AdminFolder": "root/users/admin" }

Any suggestions would be greatly appreciated.
Thanks!

you could do it by hand (like you did), but it might not be readable on the other end. escaping certain characters is part of the json spec. it's like asking, when i translate something into italian, why do the words come out in italian? they're supposed to.

Having said that by @drgottjr, you may want to reconsider the structure of the json object, in case you are in control of the receiving side, with something like:

{
"AdminFolder": {
"folder": "root",
"subfolder": "users",
"user": "admin"
}
}

B4X:

    Private JS As String
    Private root As Map
    root.Initialize
    root.Put("AdminFolder",CreateMap("folder": "root" , "subfolder": "users",  "user": "admin"))

    Private JSONGenerator As JSONGenerator
  
    JSONGenerator.Initialize(root)
  
    Log("JSON")
    JS = JSONGenerator.ToPrettyString(2)
    Log(JS)

Thanks for the feedback. I do have a work-around, but I thought there may be a more direct way of disabling the "escaping" part of the JSON spec. This works:

B4X:

    Dim Map1 As Map
    Map1.Initialize
    Dim s As String
    
    Map1.Put("AdminFolder","root/users/admin")
    
    Dim JSONGenerator As JSONGenerator
    JSONGenerator.Initialize(Map1)
    s = JSONGenerator.ToString
    s=s.Replace("\/","/")
    Log(s)

Result is:

{"AdminFolder":"root/users/admin"}

Note that the escaped output is valid. Which problem are you trying to solve?
