JSONObject json1=new JSONObject();         JSONObject json2=new JSONObject();                  json1.accumulate("extEnable",true);         json1.accumulate("extAppid","xxxxxxxxxxxxx");         json1.accumulate("directCommit",false);         json2.accumulate("extAppid","xxxxxxxxxxxxx");         json1.accumulate("ext",json2.toString());                  JSONObject json = new JSONObject();         json.accumulate("template_id","4");         json.accumulate("ext_json",json1.toString());           json.accumulate("user_version","v1.1");         json.accumulate("user_desc","first commit"); String retStr=""; retStr=httpClient.postJson(url, json); 数据发送前用json.tostring()把json转成string,"errcode":47001,"errmsg":"data format error hint: [jNVG_a06942372]",一直报这个错误，好几天了都没解决，请各位大神帮忙看看哪里出错了，多谢！！！！！
