如何不使用JSON.stringify将JSON转换为String？

Question

I've a JSON object and I want to display it in Code Mirror. Code Mirror expects string only. When I do JSON.stringify it screws up the values where it is an array instead of just string.

eg. This is the output of JSON.stringify

{
     "version": "1.1",
     "sid": "ManagementService",
     "svcVersion": "0.1",
     "oid": "getCurrentStatsForServiceTypes",
     "params": {
          "serviceTypes": "[\"rest\", \"wsdl\", \"database\", \"rss\"]"
     }
}

I want output as...

{
  "version": "1.1",
    "sid": "ManagementService",
    "svcVersion": "0.1",
    "oid": "getCurrentStatsForServiceTypes",
    "params": {
      "serviceTypes":["rest", "wsdl", "database","rss"]
    }
}

In short I want to convert the Type from Object to String without affecting the value.

Update: JSON Object is

{
  "version": "1.1",
    "sid": "ManagementService",
    "svcVersion": "0.1",
    "oid": "getCurrentStatsForServiceTypes",
    "params": {
      "serviceTypes":["rest", "wsdl", "database","rss"]
    }
}

I want the same as a string. Something like this should work.

'{
  "version": "1.1",
    "sid": "ManagementService",
    "svcVersion": "0.1",
    "oid": "getCurrentStatsForServiceTypes",
    "params": {
      "serviceTypes":["rest", "wsdl", "database","rss"]
    }
}'

Answer 1

If your serviceTypes parameter is an array, it should serialize as you indicate you want it to serialize. I have a feeling you are putting a string in that property, not an array.

When I stringify your object literal i get

"{"version":"1.1","sid":"ManagementService","svcVersion":"0.1","oid":"getCurrentStatsForServiceTypes","params":{"serviceTypes":["rest","wsdl","database","rss"]}}"

The array is not escaped, its an array.

It seems your serviceTypes are no array but a string in your Object. Try this:

obj.params.serviceTypes = JSON.parse(obj.params.serviceTypes);
return JSON.stringify(obj);
