Using MongoDB to store crawler data in Python

Now I am building a simple search engine, using the news data of Toutiao as the data source. These data are unstructured and are more suitable for storage in MongoDB.

The following is a simple example of use.

#!/usr/bin/python
# -*- coding:utf-8 -*-
 
import pymongo
 
class documentManager(object):
    def __init__(self):
        pass
 
    def connect_mongo(self):
        client = pymongo.Connection("127.0.0.1",27017)
        db = client.data_db
        collection = db.data_collection
        mydict = {"name":"Lucy", "sex":"female","job":"nurse"}
        collection.insert(mydict)
 
        for i in collection.find({"name":"Lucy"}):
            print i
 
if __name__ == '__main__':
    manager = documentManager()
    manager.connect_mongo()
