string databaseaddurl = "https://api.weixin.qq.com/tcb/databaseadd?access_token=" + jo["access_token"].ToString();

string databaseaddbody = HttpPost(databaseaddurl, "{\"env\":\"********\",\"query\":\"db.collection(\"users\").add({data:[{\"username\":\"myusername1\"},{\"username\":\"myusername2\"}]})\"}");

返回{"errcode":47001,"errmsg":"data format error hint: [UjaBtgsFE-P5hGJA]"}

求各位老师指点一下query的格式哪里有问题
