python与mongodb

1. 根据图片url下载图片到mongodb中
方法：二进制 bson

from bson import binary
from pymongo import MongoClient
client = MongoClient('127.0.0.1', 27017) #连接mongodb
db = client.photo #连接对应数据库
image_collection = db.images
data = requests.get(dic["photo_url"], timeout=10).content     # dic就是item
# 确认数据库中不存在此图片之后再保存
if not image_collection.find_one({"photo_url":dic["photo_url"]})
    dic["imagecontent"] = binary.Binary(data)
    image_collection.insert(dic)
