JS操作MongoDB

JavaScript处理MongoDB，更新数据：

#!/bin/bash
mongo=/home/zhangzhenghai/cluster/mongodb/bin/mongo
if true; then
OUT=$.out
cat <<EOF | $mongo >& | tee $OUT
use information;
db.roki.find({spch_hotwords_zh:{"\$exists": true}}).forEach(function(doc){
    var s=doc.spch_hotwords_zh["com@ro:dotrokid@ro:dothomebase:tag"];
    try {
        var json = JSON.parse(s);
        json.pop("大爷");
        var result = JSON.stringify(json);
        print(result);
        db.roki.update({"_id": doc._id}, {"\$set": {"spch_hotwords_zh.com@ro:dotrokid@ro:dothomebase:tag":result}});

    }
    catch(err) {
    }
});
EOF
fi

替换的源格式为：

{
  "_id": "xxx123",
  "basic_info": {
    "id": "xxx123",
"cmiit": "nil",
    "cy": "cn",
    "lng": "zh",
"region": "CN",
    "signLink": "true",
  },
  "spch_hotwords_zh": {
    "com@ro:dotrokid@ro:dothomebase:tag": "[\"书房开关\",\"书房开关 L1\",\"开关\",\"书房开关 L2\",\"书房开关 L3\",\"客厅开关\",\"面板\",\"客厅开关 L1\",\"客厅开关 L2\",\"客厅开关 L3\",\"阳光茶室\",\"灯\",\"阳光茶室 L1\",\"阳光茶室 L2\",\"阳光茶室 L3\",\"厨房开关\",\"厨房开关 L1\",\"琴房\",\"琴房 L1\",\"琴房 L2\",\"琴房 L3\",\"餐厅开关\",\"餐厅开关 L1\",\"餐厅开关 L2\",\"餐厅开关 L3\",\"包厢开关\",\"包厢开关 L1\",\"包厢开关 L2\",\"包厢开关 L3\",\"卫生间开关\",\"卫生间开关 L1\",\"卫生间开关 L2\",\"玄关开关\",\"玄关开关 L1\",\"玄关开关 L2\",\"存茶室开关\",\"存茶室开关 L1\",\"存茶室开关 L2\",\"存茶室开关 L3\",\"大爷\"]",
    "com@ro:dotrokid@ro:dotsystem@ro:dotexecuter:trigger": "[\"早上好\",\"晚上好\"]"
  },
  "PUSH-MESSAGE": {
    "device_type": "ANDROID"
  },
  "voice_trigger_zh": {
    "": "{\"rid\":\"1499247475884\",\"triggers\":[\"晚上好\"],\"enable\":true,\"executions\":[{\"voice\":\"tts 晚上好\",\"delay\":0},{\"voice\":\"播放舒缓音乐\",\"delay\":1200},{\"voice\":\"关机\",\"delay\":0}]}",
    "": "{\"rid\":\"1499247476350\",\"triggers\":[\"早上好\"],\"enable\":true,\"executions\":[{\"voice\":\"tts 早上好\",\"delay\":0},{\"voice\":\"播报天气\",\"delay\":0},{\"voice\":\"播放新闻\",\"delay\":1200},{\"voice\":\"关机\",\"delay\":0}]}"
  },
  "LOCATION": {
    "country": "中国"
  }
}

程序执行完后：

{
  "_id": "xxx123",
  "basic_info": {
    "id": "xxx123",
"cmiit": "nil",
    "cy": "cn",
    "lng": "zh",
"region": "CN",
    "signLink": "true",
  },
  "spch_hotwords_zh": {
    "com@ro:dotrokid@ro:dothomebase:tag": "[\"书房开关\",\"书房开关 L1\",\"开关\",\"书房开关 L2\",\"书房开关 L3\",\"客厅开关\",\"面板\",\"客厅开关 L1\",\"客厅开关 L2\",\"客厅开关 L3\",\"阳光茶室\",\"灯\",\"阳光茶室 L1\",\"阳光茶室 L2\",\"阳光茶室 L3\",\"厨房开关\",\"厨房开关 L1\",\"琴房\",\"琴房 L1\",\"琴房 L2\",\"琴房 L3\",\"餐厅开关\",\"餐厅开关 L1\",\"餐厅开关 L2\",\"餐厅开关 L3\",\"包厢开关\",\"包厢开关 L1\",\"包厢开关 L2\",\"包厢开关 L3\",\"卫生间开关\",\"卫生间开关 L1\",\"卫生间开关 L2\",\"玄关开关\",\"玄关开关 L1\",\"玄关开关 L2\",\"存茶室开关\",\"存茶室开关 L1\",\"存茶室开关 L2\",\"存茶室开关 L3\"]",

  },
  "PUSH-MESSAGE": {
    "device_type": "ANDROID"
  },
  "voice_trigger_zh": {
    "": "{\"rid\":\"1499247475884\",\"triggers\":[\"晚上好\"],\"enable\":true,\"executions\":[{\"voice\":\"tts 晚上好\",\"delay\":0},{\"voice\":\"播放舒缓音乐\",\"delay\":1200},{\"voice\":\"关机\",\"delay\":0}]}",
