1. 切换到 virtualenv 环境

    . /pyenv/bin/activate

2. 安装pymongo

    pip install pymongo

3. 安装flask_mongoengine

    pip install flask_mongoengine

from flask_mongoengine import MongoEngine

#--

#进行配置

app.config['MONGODB_SETTINGS'] = {

    'db'    : 'the_way_to_flask',

    'host'  : 'localhost',

    'port'  : 27017

}

＃创建mongo原型

mdb = MongoEngine()

mdb.init_app(app)

class Address(mdb.Document):

    name = mdb.StringField()

    address = mdb.StringField()

    # 查询 Address.objects(name="zhangsan").first()

    # 添加 Address(name='lisi', address='lisi@gmail.com').save()

    # 删除 Address.delete()

    # 更新 Address.update(name="lisi@outlook.com")

from models import Address

from flask import jsonify

#--

@app.route('/mdb_list',methods=['get'])

def mdb_list():

    name = request.args.get('name')

    address = request.args.get('address')

    Addr = Address.objects(name=name,address=address).first()

    if not Addr:

        Address(name=name , address=address).save()

        return jsonify({'code':1,'message':'success'})

    else:

        return jsonify(Addr.to_json())
