Question

The problem may be with the actual client, but he’s not responding on github, so I’ll give this a shot!

I’m trying to post, in the body, nested JSON:

{
   "rowkeys":[
      {
         "rowkey":"rk",
         "columns":[
            {
               "columnname":"cn",
               "columnvalue":"{\"date\":\"2011-06-21T00:53:10.309Z\",\"disk0\":{\"kbt\":31.55,\"tps\":6,\"mbs\":0.17},\"cpu\":{\"us\":5,\"sy\":4,\"id\":90},\"load_average\":{\"m1\":0.85,\"m5\":0.86,\"m15\":0.78}}",
               "ttl":10000
            },
            {
               "columnname":"cn",
               "columnvalue":"cv",
               "ttl":10000
            }
         ]
      },
      {
         "rowkey":"rk",
         "columns":[
            {
               "columnname":"cn",
               "columnvalue":"fd"
            },
            {
               "columnname":"cn",
               "columnvalue":"cv"
            }
         ]
      }
   ]
}

When I remove the columnvalue’s json string, the POST works. Maybe there’s something I’m missing regarding escaping? I’ve tried a few built in escape utilities to no avail.

var jsonString='the json string above here';

var sys = require('sys'),
      rest = require('fermata'), // https://github.com/andyet/fermata
         stack = require('long-stack-traces');

        var token = ''; // Username
        var accountId = ''; // Password

        var api = rest.api({
             url : 'http://url/v0.1/',
             user : token,
             password : accountId
        });

        var postParams = {
             body: jsonString
        };

        (api(postParams)).post(function (error, result) {
               if (error)
                    sys.puts(error);    

           sys.puts(result);
        });

The API I’m posting to can’t deserialize this.

            {

               "columnvalue":"cv",
               "ttl":10000
            }
         ]
      },
      {
         "rowkey":"rk",
         "columns":[
            {
               "columnname":"cn",
               "columnvalue":"fd"
            },
            {
               "columnname":"cn",
               "columnvalue":"cv"
            }
         ]
      }
   ]
}

Dual problems occuring at the same occurred led me to find an issue with the fermata library handling large JSON posts. The JSON above is just fine!
