from pymongo import *
# conn = MongoClient(host='192.168.1.188',port='27017')
client = MongoClient("mongodb://192.168.1.188:27017")
db_1 = client.test01 #方式1
db_2 = client['test01'] #方式2
col_1 = db_1.spider #方式1
col_2 = db_2['spider'] #方式2
#插入
data = {'id': 123, 'name': 'jike', 'age': 20, 'salary': 88888888}
col_1.insert(data)
#查找
# content = col_1.find({'age': 20})
content = col_1.find({})
print(type(content))
for row in content:
id = row['id']
name = row['name']
age = row['age']
print(id)
print(name)
print(age)
#更新
col_1.update_one({'age': 20}, {'$set':{'name': 'kingname'}})
col_1.update_many({'age': 20}, {'$set':{'age': 30}})
#删除
col_1.delete_one({'name': 'kingname'})
col_1.delete_many({'name': 'kingname'})
