【已解决】把本地mp3文件存入在线Mongo中且填写meta信息

MongoDB crifan 312浏览 0评论

之前通过代码批量把一堆的mp3和pdf等文件保存到在线的mongo中了。现在手上有3个mp3文件:

现在本地的fs.files中单个文件是:

<code>&gt; db.fs.files.findOne()
{
        "_id" : ObjectId("5b20d5ec7f4d384006e91f18"),
        "contentType" : "audio/mpeg",
        "chunkSize" : 261120,
        "metadata" : {
                "song" : {
                        "singers" : [ ]
                },
                "fitAgeStart" : 3,
                "topics" : [
                        "Wisdom",
                        "Animals",
                        "Villain"
                ],
                "storybook" : {
                        "publisher" : "Mathew Price",
                        "isFiction" : "是",
                        "lexileIndex" : "",
                        "awards" : "",
                        "authors" : [
                                "Atsuko Morozumi"
                        ],
                        "foreignCountry" : "英国"
                },
                "keywords" : {
                        "fromName" : [
                                "go away Mr Wolf",
                                "Mr wolf",
                                "Go away",
                                "wolf"
                        ],
                        "other" : [ ],
                        "fromContent" : [
                                "knock!",
                                "go away",
                                "Mr Wolf",
                                "quickly shut the door"
                        ]
                },
                "name" : "Go away, Mr Wolf",
                "resourceType" : "storybook",
                "mainActors" : [
                        "three little pigs",
                        "Mr.Wolf"
                ],
                "contentAbstract" : "一个教小朋友警惕坏人的故事,狼先生扮成各种样子前来敲小猪家的们,3只小猪识别了狼的真面目,把门关上不让狼进来,一直到爸爸回来把发生的事情告诉爸爸听。",
                "isSeries" : false,
                "series" : {
                        "number" : 0,
                        "name" : ""
                },
                "fitAgeEnd" : 4,
                "fileInfo" : {
                        "isAudio" : true,
                        "contentType" : "audio/mpeg",
                        "name" : "Go away, Mr Wolf.mp3",
                        "suffix" : "mp3"
                }
        },
        "filename" : "Go away, Mr Wolf.mp3",
        "length" : 1613790,
        "uploadDate" : ISODate("2018-06-13T08:29:32.493Z"),
        "md5" : "3fa28e2ef5e7e56e15f797cd169845cc"
}
&gt;
</code>

需要保存mp3到mongo中,且把相关的信息都保存进去。

mongo save file with meta

$meta — MongoDB Manual

Consider MongoDB and GridFS for meta, thumbnails, transcoded video etc · Issue #46 · jansmolders86/mediacenterjs

Adding a field to the JSON of a PDF in MongoDB => NullPointerException for the river · Issue #91 · richardwilly98/elasticsearch-river-mongodb

mongo save file with metadata

File: GridFS

mongofiles save with metadata

mongofiles — MongoDB Manual

貌似没有metadata的选项啊

去看看Mongo Compass中是否有插入文件,且设置metadata的功能

貌似没有插入文件的选项?

去搜:

自己看了看:

貌似导入的是json

但是貌似没发指定mp3文件?

[JAVA-1013] Saved extra fields for Gridfs does not go in metadata sub-document – MongoDB

mongo 保存 metadata

mongo 保存 GridFS  metadata

mongodb开发—GridFS文件存储 – CSDN博客

难道是只能和之前一样,去写python代码去保存file,同时传递metadata了?

mongo compass gridfs

mongo compass support gridfs

Creating Compass Plugins — MongoDB Compass stable

Visualizing your data with MongoDB Compass | MongoDB

【未解决】尝试用Mongo Management Studio去实现导入文件到Mongo的gridfs且带metadata信息

看到:

https://www.guru99.com/top-20-mongodb-tools.html

“15) NoSQL Manager:

* File Manager Tool to work with GridFS”

去看看

NoSQL Manager – GUI tool with intelligent Shell certified by MongoDB

貌似也没有gridfs上传文件的选项,更别说metadata了。

“File Manager tool to work with GridFS”

是支持gridfs上传文件的

不清楚是否支持修改metadata?

去试试

下载之前也先去看看功能:

NoSQL Manager for MongoDB – Features – NoSQL Manager – GUI tool with intelligent Shell certified by MongoDB

Managing GridFS

File Manager tool to work with GridFS

free版本都支持。

Downloads – NoSQL Manager – GUI tool with intelligent Shell certified by MongoDB

下载:

NoSQL Manager for MongoDB Freeware

发现是exe版本的:

才注意到:

“System Requirements

* Microsoft Windows Vista or higher

* Microsoft .Net Framework 4.5”

而此处是Mac,用不了。

再去确认:

<code>mongofiles put --help
</code>

和:

<code>mongofiles --help
</code>

输出一样:

都不支持put时传递metadata

看来真的只能去写python代码去保存了。

【已解决】mongo的shell中find返回多个有限个数的结果

【总结】

最后是写代码实现:

把mp3文件存入进去后,且还带着metadata的:

<code># -*- coding: utf-8 -*-

import pymongo
from pymongo import MongoClient
import gridfs

# from pymongo.objectid import ObjectId
# from pymongo import objectid
from bson.objectid import ObjectId

# import pprint

import sys
sys.path.append("libs/crifan")
