【已解决】把本地的音频字幕等数据存储到本地MongoDB数据库中

“能在MongoDB中保存的Document尺寸一般有最大16Mbyte的限制。这对于保存一般的文本文件是非常足够的尺寸，但要保存一些巨大的文本文件以及视频等Binary data时，就会出现超出16Mbyte的情况。想在MongoDB中保存16Mbyte以上的文件时，通过使用GridFS这种接口，可以将数据进行多个分割来进行保存。”

所以看起来是：

此处对于pdf，mp3等，即使小于16MB，为了统一存储方式，也还是都用GridFS吧。

mongodb gridfs 存储文件

GridFS 基于MongoDB的分布式文件存储系统 | 梁桂钊的博客

<code>&gt; show collections
testCollection
&gt; db.fs.files.findOne()
null
</code>

还是没有解释，如何用GridFS去保存文件

mongodb gridfs to store file

MongoDB GridFS

GridFS – Mongodb 教程 – 极客学院Wiki

通过tab可以看到此处有mongofiles：

<code>➜  ~ mongo
mongo         mongodump     mongofiles    mongoperf     mongorestore  mongostat
mongod        mongoexport   mongoimport   mongoreplay   mongos        mongotop
</code>

GridFS — MongoDB Manual 3.6

When to Use GridFS

什么时候才需要去用GridFS去存储文件数据：

文件大小超过16MB

MongoDB本身基于的document是基于BSON的，最大只支持16MB
超过16MB，无法直接高效率的保存

文件所在文件系统对文件个数有限制（比如不能超过1000个之类的）

用GridFS可以存储任意个数的文件

需要读取访问大文件中的某段数据

传统方式：需要加载整个文件到内存中，接着才能读取其中指定的部分数据
GridFS：无需加载整个文件，可以高效的实现，类似于seek去定位，读取某段数据

希望文件和原数据在物理上存储在多个不同地方，且又希望实时保证同步

GridFS支持物理上地分布式存储和自动保持同步

不要，不建议，用GridFS：

去存储那些，每次操作都是针对文件的整个内容的操作

-》否则换用GridFS，并不能提高效率

文件大小小于16MB

直接用MongoDB存即可

用GridFS去保存文件的话有2种方式：

driver

MongoDB Drivers and Client Libraries — MongoDB Manual 3.6
中介绍了很多
比如：

Python

命令行工具：mongofiles

不同系统文件不同

Windows：mongofiles.exe
Linux类系统，包括Mac：mongofiles

which mongofiles
/usr/local/bin/mongofiles

方式：

chunks：存二进制数据块

默认chunk大小255KB
默认用：fs.files

files：存储文件的原数据（描述信息）

默认用：fs.chunks

此处的fs被称为bucket

【已解决】GridFS保存文件时如何得到文件的id或_id

还是去试试再说

去实际操作试试

结果由于路径问题，无法存入：

<code>➜  英语资源 mongofiles -d gridfs put "/Users/crifan/dev/dev_root/company/xxx/数据/xx/英语资源/All\ Aboard\ Reading/音频/Otto\ the\ Cat.MP3"
2018-03-28T14:25:01.763+0800    connected to: localhost
2018-03-28T14:25:01.765+0800    Failed: error while opening local file '/Users/crifan/dev/dev_root/company/xxx/数据/xxx/英语资源/All\ Aboard\ Reading/音频/Otto\ the\ Cat.MP3' : open /Users/crifan/dev/dev_root/company/xx/数据/xx/英语资源/All\ Aboard\ Reading/音频/Otto\ the\ Cat.MP3: no such file or directory
</code>

mongofiles no such file or directory

通过ll发现：

<code>➜  英语资源 ll All\ Aboard\ Reading/音频/Otto\ the\ Cat.MP3
-rwxr-xr-x  1 crifan  staff   8.0M  3  7 12:23 All Aboard Reading/音频/Otto the Cat.MP3
</code>

把反斜杠去掉即可：

<code>➜  英语资源 mongofiles -d gridfs put "/Users/crifan/dev/dev_root/company/xx/数据/xx/英语资源/All Aboard Reading/音频/Otto the Cat.MP3"
2018-03-28T14:43:08.463+0800    connected to: localhost
added file: /Users/crifan/dev/dev_root/company/xx/数据/xx/英语资源/All Aboard Reading/音频/Otto the Cat.MP3
</code>

然后就可以去搜出来文件了：

<code>
&gt; db.fs.files.find()
{ "_id" : ObjectId("5abb397ca4bc71fc7d71c7bd"), "chunkSize" : 261120, "uploadDate" : ISODate("2018-03-28T06:43:08.613Z"), "length" : 8338105, "md5" : "b7660d833085e9e1a21813e4d74b0cc3", "filename" : "/Users/crifan/dev/dev_root/company/xx/x/英语资源/All Aboard Reading/音频/Otto the Cat.MP3" }
&gt; db.fs.files.find().pretty()
{
    "_id" : ObjectId("5abb397ca4bc71fc7d71c7bd"),
    "chunkSize" : 261120,
    "uploadDate" : ISODate("2018-03-28T06:43:08.613Z"),
    "length" : 8338105,
    "md5" : "b7660d833085e9e1a21813e4d74b0cc3",
    "filename" : "/Users/crifan/dev/dev_root/xxx/英语资源/All Aboard Reading/音频/Otto the Cat.MP3"
}
</code>

然后去找chunks：

<code>&gt; db.fs.chunks.find({files_id: "5abb397ca4bc71fc7d71c7bd"})
</code>

发现要带上ObjectId才能搜出来：

<code>&gt; db.fs.chunks.find({files_id: ObjectId("5abb397ca4bc71fc7d71c7bd")})
</code>

但是：

【已解决】MongoDB的GridFS中只返回file的chunks的个数而不返回chunks.data

再去下载文件：

【已解决】MongoDB的GridFS中基于文件名或id去下载文件

顺带也看到了：

“–type <MIME>¶

Provides the ability to specify a MIME type to describe the file inserted into GridFS storage. mongofiles omits this option in the default operation.

Use only with mongofiles put operations.”

再去试试–type

mongofiles – MongoDB GridFS Utility – Linux Man Pages (1)

mongofiles — MongoDB Manual

“–type <MIME>

Provides the ability to specify a MIME type to describe the file inserted into GridFS storage. mongofiles omits this option in the default operation.

Use only with mongofiles put operations.”

只能用于put操作。

而需要先去找找确定的MIME的写法：

【已解决】常见文件的MIME的写法

然后就可以去试试，加上MIME了：

<code>➜  英语资源 mongofiles -d gridfs put "Otto the Cat-withMIME.MP3"  --type audio/mpeg --replace --local "/Users/crifan/dev/dev_root/xxx/英语资源/All Aboard Reading/音频/Otto the Cat.MP3"
2018-03-29T09:38:44.765+0800    connected to: localhost
2018-03-29T09:38:44.775+0800    removed all instances of 'Otto the Cat-withMIME.MP3' from GridFS

added file: Otto the Cat-withMIME.MP3
</code>

效果：

<code>&gt; db.fs.files.find().pretty()
{
    "_id" : ObjectId("5abc43a4a4bc712159a35cd9"),
    "chunkSize" : 261120,
    "uploadDate" : ISODate("2018-03-29T01:38:44.853Z"),
    "length" : 8338105,
    "md5" : "b7660d833085e9e1a21813e4d74b0cc3",
    "filename" : "Otto the Cat-withMIME.MP3",
    "contentType" : "audio/mpeg"
}
</code>

再去试试删除文件：

【已解决】用mongofiles去删除GridFS中的文件

然后再去：

【无法也无须解决】用mongofiles给GridFS中添加文件时添加额外参数属性字段

那就后续折腾API的时候，再去保存额外参数。

然后可以开始去折腾写Python代码，去调用gridfs去保存文件了，且可以同时去保存额外参数了：

【已解决】用Python去连接本地mongoDB去用GridFS保存文件

然后接着要去：

【已解决】python解析excel文件并读取其中的sheet和row和column的值

然后接着就是去调试代码，保存本地的所有的音频文件到本地的mongoDB中了：

metadata数据如下：

有unicode，有list，有None

<code>2018/03/30 03:21:30 LINE 230  INFO    metadataDict={'publisher': u'Penguin US', 'authorList': [u'Ludwig Bemelmans'], 'keywordContentKeywordList': None, 'storybookSeriesNumber': 1L, 'storybookFilePath': u'\u82f1\u8bed\u8d44\u6e90\\Madeline\\\u7535\u5b50\u4e66\\Madeline.pdf', 'lexileIndex': None, 'keywordStorybookNameKeywordList': [u'Madeline '], 'fitAgeRange': u'4-5years', 'keywordStorybookName': u'Madeline ', 'hasAudioFile': u'\u6709', 'hasStorybookFile': u'\u6709PDF\u7248', 'audioFilePath': u'\u82f1\u8bed\u8d44\u6e90\\Madeline\\\u97f3\u9891\\Madeline.mp3', 'keywordTopicList': [u'Family members', u'Sick'], 'isFiction': u'Fiction', 'foreignCountry': u'\u7f8e\u56fd', 'awards': u'\u51ef\u8fea\u514b\u5956\u94f6\u5956', 'contentSimpleIntro': u'\u9a6c\u5fb7\u6797\u751f\u75c5\u4e86\uff0c\u5272\u4e86\u9611\u5c3e\u7684\u9a6c\u5fb7\u6797\u4f4f\u8fdb\u4e86\u533b\u9662\uff0c\u6536\u5230\u4e86\u7238\u7238\u5988\u5988\u9001\u7684\u9c9c\u82b1\u548c\u7cd6\u679c\u3002\u5176\u4ed6\u59d1\u5a18\u4eec\u770b\u4e86\u9a6c\u5fb7\u6797\u7684\u793c\u7269\u7adf\u7136\u4e5f\u60f3\u5f97\u9611\u5c3e\u708e\u3002\u662f\u4e0d\u662f\u5f88\u6709\u8da3\u3002', 'type': 'storybook', 'keywordMainActorList': [u'Madeline '], 'keywordStorybookSeries': u'Madeline'}
</code>

去保存进去，看看保持后的效果如何：

PyCharm的Mongo插件看到的效果：

<code>&gt; db.fs.files.find().pretty()
{
    "_id" : ObjectId("5abde606a4bc7157b3b578cd"),
    "contentType" : "audio/mpeg",
    "chunkSize" : 261120,
    "metadata" : {
        "publisher" : "Penguin US",
        "authorList" : [
            "Ludwig Bemelmans"
        ],
        "keywordContentKeywordList" : null,
        "storybookSeriesNumber" : NumberLong(1),
        "storybookFilePath" : "英语资源\\Madeline\\电子书\\Madeline.pdf",
        "lexileIndex" : null,
        "keywordStorybookNameKeywordList" : [
            "Madeline "
        ],
        "fitAgeRange" : "4-5years",
        "keywordStorybookName" : "Madeline ",
        "hasAudioFile" : "有",
        "hasStorybookFile" : "有PDF版",
        "audioFilePath" : "英语资源\\Madeline\\音频\\Madeline.mp3",
        "keywordTopicList" : [
            "Family members",
            "Sick"
        ],
        "isFiction" : "Fiction",
        "foreignCountry" : "美国",
        "awards" : "凯迪克奖银奖",
        "contentSimpleIntro" : "马德林生病了，割了阑尾的马德林住进了医院，收到了爸爸妈妈送的鲜花和糖果。其他姑娘们看了马德林的礼物竟然也想得阑尾炎。是不是很有趣。",
        "type" : "storybook",
        "keywordMainActorList" : [
            "Madeline "
        ],
        "keywordStorybookSeries" : "Madeline"
    },
    "filename" : "Madeline.mp3",
    "length" : 4808605,
    "uploadDate" : ISODate("2018-03-30T07:23:50.210Z"),
    "md5" : "df3751f1257806712a51353bd941ccb1"
}
</code>

Python中的None，保存后是JSON中的null

另外还有：

excel中的数字1，保存后是：

“storybookSeriesNumber” : NumberLong(1)

总之：还是不错的。
