sanic-mongo

sanic的mongodb异步工具,灵感来源自 官方例子.是%5Bmotor%5D(https://motor.readthedocs.io/en/stable/tutorial-asyncio.html) 的封装, 目的只是为了简化操作.

更新

• v1.7.1 修正了mongo连接权限可能引发的问题,现在可以配置每个连接是否是只能连database,默认为False.{"uri":xxxx,"only_db":True}
• v1.6.0 修正了验证无法通过的问题
• v1.5.0 将接口调整至和sanic-aioorm一致.

特点 Features

• motor 支持的操作都支持
• 支持3.5版本以上的
• 支持多数据库
• 支持mongodb和gridfs

依赖 Requirements

1. motor>=1.1
2. pymongo>=3.4.0
3. sanic>=0.4.1

> 安装 Installation

• pip install sanic-mongo

用法

mongo需要给`app.config`设置关键字`MONGO_URIS`,它是一个由mongodb名字和url组成的字典. 同时也可以使用`Mongo.SetConfig(app,**kws)来注册kws的内容到`MONGO_URIS. 而使用的时候可以访问`app.mongo[mongodb名字]`访问对应的db

gridfs与之类似,只是关键字是`GRIDFS_SETTINGS`,而访问需要使用`app.GridFS[GridFS名字]`

例子 Example

1. mongodb

from sanic import Sanic
from sanic.response import json
from sanic_mongo import Mongo
app = Sanic(__name__)
mongo_uri = "mongodb://{host}:{port}/{database}".format(
    database='test',
    port=27017,
    host='localhost'
)

Mongo.SetConfig(app,test=mongo_uri)
Mongo(app)

@app.get('/objects')
async def get(request):
    docs = await app.mongo['test'].test_col.find().to_list(length=100)
    for doc in docs:
        doc['id'] = str(doc['_id'])
        del doc['_id']
    return json(docs)


@app.post('/objects')
async def new(request):
    doc = request.json
    print(type(app.mongo['test']))
    object_id = await app.mongo['test']["test_col"].save(doc)
    return json({'object_id': str(object_id)})


if __name__ == "__main__":
    app.run(host='127.0.0.1', port=8000,debug=True)

1. gridfs

from sanic import Sanic
from sanic.response import json,text
from sanic_mongo import GridFS

app = Sanic(__name__)
mongo_uri = "mongodb://{host}:{port}/{database}".format(
    database='test',
    port=27017,
    host='localhost'
)

GridFS.SetConfig(app,test_fs=(mongo_uri,"fs"))
GridFS(app)

@app.get('/pics')
async def get(request):
    cursor = app.GridFS["test_fs"].find()
    result = [{i._id:i.name} async for i in cursor]
    return json({"result":result})


@app.post('/pics')
async def new(request):
    doc = request.files.get('file')

    async with app.GridFS["test_fs"].open_upload_stream(filename=doc.name,
        metadata={"contentType": doc.type}) as gridin:

        object_id = gridin._id
        await gridin.write(doc.body)

    return json({'object_id': str(object_id)})


if __name__ == "__main__":
    app.run(host='127.0.0.1', port=8000,debug=True)
