Talk:LlJsonSetValue

Safe strings

Passing strings verbatim to llJsonSetValue or llList2Json is not safe. One way to escape strings properly to make them safe for use with both is to use this function: <lsl> string String2Json(string s) {

   return llGetSubString(llList2Json(JSON_OBJECT, [s,""]), 1, -5);

} </lsl> Examples: <lsl> llOwnerSay(String2Json(llUnescapeURL("%09"))); // outputs: Object: "\t" llOwnerSay(String2Json("\n")); // outputs: Object: "\n" llOwnerSay(String2Json("this \"string\" is not safe")); // outputs: Object: "this \"string\" is not safe" llOwnerSay(String2Json("\"ab\"")); // outputs: Object: "\"ab\""

// Examples of use with the corresponding functions: llOwnerSay(llJsonSetValue("[]", [0], String2Json("this \"string\" is not safe"))); llOwnerSay(llList2Json(JSON_ARRAY, [String2Json("this \"string\" is not safe")])); // both output: Object: ["this \"string\" is not safe"] </lsl>

Sadly, even this isn't a complete solution. With a URL like "http://www.google.com/", you'll get a "leaning-toothpicks" style value, but a call to llJsonSetValue() still won't pack it in correctly. -- Lavanya Hartnell 7:45, 11 August 2014 (PDT)
