Sometime smartfox adds quotes arround my uservariable

I noticed when setting a uservariable in the js-client with a custom json-string, smartfox adds quotes around them. I had a hunch this might me caused by smartfox using json itself or something. I tried adding white space to the start and end and then no quotes where added. Since whitespace has no influence on the json-data, i'm using this fix:
Code: Select all
var str = " \n " + JSON.stringify(newObj) + " \n ";
var uv = new SFS2X.Entities.Variables.SFSUserVariable("filter", str);
For now it works, but it's a bit hacky.... and its better if smartfox doesn't change my strings, not even by just adding quotes.
I'm a bit low on time, so i didn't dig very deep into it... so if i'm mistaken, please correct me
.

You should please better explain. Where exactly do you see such additional quotes appear?
We tried creating a simple object like this:
var obj = {"one":"this is one","two":2}
After JSONizing it and setting a User Variable, in the AdminTool we see the string reported as expected:
{"one":"this is one","two":2}
So nothing wrong here.
Can you elaborate? Thanks.

Thank for your speedy response. I try to be a little more clearer this time, but i thought maybe you guys could have guessed the cause of it by just mentioning some stray quotes.
Anyway this is my code:
Code: Select all
var obj = {k1 :'some val 1', k2: 'some val 2'}
var str = JSON.stringify(obj);
console.log("=|" + str + "|=");
var uv = new SFS2X.Entities.Variables.SFSUserVariable("jsonStr", str);
sfs.send(new SFS2X.Requests.System.SetUserVariablesRequest([uv]));
sfs.addEventListener(SFS2X.SFSEvent.USER_VARIABLES_UPDATE, function(){
console.log( " -|" +$rootScope.sfs.mySelf.getVariable("jsonStr").value+"|-" );
}, this);
The output is below... i added -| and |- to make the boundaries clear.
Code: Select all
=|{"k1":"some val 1","k2":"some val 2"}|=
-|"{"k1":"some val 1","k2":"some val 2"}"|-
now with the same code as before but added whitespace to str:
Code: Select all
var str = " " + JSON.stringify(obj) + " ";
output as expected:
Code: Select all
=| {"k1":"some val 1","k2":"some val 2"} |=
-| {"k1":"some val 1","k2":"some val 2"} |-

Thank you for the clarification and example.
Actually this is the expected behavior, because the API use JSON internally. So as you are placing a JSON string inside a JSON, the API add those extra quotes to treat it as a string. This happens with any string starting and ending with { } or [ ].
You can add a single extra space at the beginning or the end of your JSON string, or strip the extra quotes when you are expecting a JSON string.

Thanks for your explanation. Now i at least understand why whitespaces 'protect' my json string
