01 今日内容概要

1.1 基于Flask开发Web微信；

• 爬虫；
• Flask知识；

02 内容回顾：flask上下文

2.1 Flask的上下文管理回顾；

　　2.1.1 threading.local；

• 应用：Flask上下文管理中的Local类更加高级
• DBUtils线程池的模式：为每个线程创建一个连接

　　2.1.2 SQLAlchemy；

　　2.1.3 什么是栈？后进先出，push和pop方法；

　　2.1.4 __getattr__方法；

2.2 Flask上下文管理机制；

2.2.1 Flask程序有几个Local和LocalStack？

• 请求LocalStack，帮助开发对stack对应列表操作
• 应用LocalStack，帮助开发对stack对应列表操作

2.2.2 为什么要创建两个Local或者LocalStack？

• 编写离线脚本时，需要配置文件，而配置文件存放在app中；
• 编写离线脚本时，不需要请求相关数据

03 内容回顾：多app应用

multi_app.py;

from flask import Flask
from werkzeug.wsgi import DispatcherMiddleware
from werkzeug.serving import run_simple

app1 = Flask("app01")
app1.config['DB'] = 123
app2 = Flask("app02")
app2.config['DB'] = 456


@app1.route('/web')
def web():
    print('web')
    return 'cuixiaozhao'


@app1.route('/news')
def news():
    print('news')
    return 'cuixiaozhao'


@app2.route('/admin')
def admin():
    print('admin')
    return 'cuixiaozhao'


@app2.route('/article')
def article():
    print('article')
    return 'cuixiaozhao'


'''
/web
/news
/admin
'''
app = DispatcherMiddleware(app1, {
    '/app2': app2,
})
if __name__ == '__main__':
    run_simple(hostname='127.0.0.1', port=5000, application=app)

离线脚本.py;

from multi_app import app1
from multi_app import app2

with app1.app_context():
    pass  # 为app1创建数据库;
    with app2.app_context():
        pass  # 为app2创建数据库

04 内容回顾：面向对象和数据库

4.1 面向对象的认识；

4.2 特殊方法；

　　4.2.1 __enter__

　　4.2.2 __exit__

4.3 约束

　　4.3.1 接口（java）

　　4.3.2 抽象方法、抽象类；

　　4.3.3 Python本无接口，但有抽象方法抽象类

　　4.3.4 Python中继承+抛出异常做

4.4 metaclass的作用:指定类由哪个type创建（type泛指继承type的所有类）

# class Base(object):
#     def send(self):
#         raise NotImplemented("子类中必须要实现send方法")
#
# class Foo(Base):
#     def send(self):
#         print('13811221893')
#
#
# obj = Foo()
# obj.send()
import abc


class Base(metaclass=abc.ABCMeta):

    @abc.abstractmethod
    def send(self):
        pass

    def func(self):
        print(123)


class Foo(Base):
    def send(self):
        print("发送信息给gf")
obj = Foo()
obj.send()
obj.func()

4.5 数据库

4.5.1 Django的数据库锁；

4.5.2 数据库引擎

• InnoDB——表|行、无事务、慢；
• MyIsam——表、无事务、快；

4.5.3 数据库如何加锁？

• 终端1：begin; select * from tb for update;commit;
• 终端2:begin;select * from tb for update;commit;

4.5.4 什么时候需要加锁呢？

• 记数
• 应用场景——商品数量更新；

4.5.5 了解

• 视图，即虚拟表
• 触发器，增加、修改、删除前后做操作，但是性能比较低，一般不用；
• 函数，返回一个值；
• 存储过程，返回一个结果集；

4.5.6 索引

• 主键索引
• 联合索引
• 唯一索引
• 联合唯一索引
• 索引的注意事项：命中索引；无法命中：LIke、函数、or、不等于

4.5.7 慢日志？

• 将查询时间久
• 未命中索引
• 修改数据库配置文件——slow_query_log = ON;long_query_time = 2;slow_query_log_file = /usr/slow.log;log_query_not_using_indexes = ON

4.5.8 SQL性能测试-通过执行计划；

• explain select * from tb;

4.5.9 数据库优化方案;

• 不适用select *;
• select id,1 from tb;
• 短索引
• 使用连表操作不使用子查询；
• 列的固定长度在前面
• 分库分表（水平、垂直）　
• 使用组合索引》索引合并
• 内存代替连表
• limit 1
• 读写分离与主从复制一起使用（主从数据一致，但是实现了读写分离）
• 分页，越往后越慢，记录当前页面的最大和最小id；
• 使用Redis做缓存；仅限于热点数据；但是注意缓存数据量很大，一旦Redis宕机，MySQL会出现雪崩的风险；做Redis的高可用；

05 内容回顾：爬虫

5.1 requests模块的参数；

• url
• headers
• cookies
• data
• json
• params
• proxy
• 文件上传
• SSL证书

5.2 bs4

• find
• find_all
• text
• attrs

5.3 爬虫套路

• 汽车之家，没防爬虫策略
• 抽屉
• 抽屉登录
• github csrf_token
• 拉勾网 自生成token，放在请求头，构造特殊请求头；

5.4 PIL生成点线杂乱验证码，反解效率更低，使用无意义；谷歌开源的TensorFlow进行机器学习；

• 成立团队自行开发进行做验证码破解；
• 购买爬虫相关验证码破解服务；
• 手工登录，然后获取cookies，再进行爬取；

06 Web微信:获取二维码（一）

6.1 基于Flask开发Web微信；

6.2 什么是长轮询？为了希望实时得到一个数据；前端写递归，后端夯住；

07 Web微信：获取二维码（二）

7.1 创建Flask项目；

7.2 动态获取微信二维码;

10.1 xml解析器函数的引入，将xml格式的文档转化为字典类型；

import re

data = 'window.QRLogin.code = 200; window.QRLogin.uuid = "IaFEIY2ncA==";'

ret = re.findall('uuid = "(.*)";', data)[0]
#print(ret)


#text = '<error><ret>0</ret><message></message><skey>@crypt_7f94ab6d_09c6f5c641735b9d508b2973de7e1c73</skey><wxsid>dxtAt/oUed7drgJw</wxsid><wxuin>2150889942</wxuin><pass_ticket>DgAlY28j5CsCBMamz1h0FU42CAK6Bn%2BLk888LtaZnsOlckkPWFpgMu0KBFY91IUi</pass_ticket><isgrayscale>1</isgrayscale></error>'
from bs4 import BeautifulSoup

def xml_parse(text):
    result = {}
    soup = BeautifulSoup(text,'html.parser')
    tag_list = soup.find(name='error').find_all()
    for tag in tag_list:
       result[tag.name] = tag.text
    return result
v = '<error><ret>0</ret><message></message><skey>@crypt_7f94ab6d_09c6f5c641735b9d508b2973de7e1c73</skey><wxsid>dxtAt/oUed7drgJw</wxsid><wxuin>2150889942</wxuin><pass_ticket>DgAlY28j5CsCBMamz1h0FU42CAK6Bn%2BLk888LtaZnsOlckkPWFpgMu0KBFY91IUi</pass_ticket><isgrayscale>1</isgrayscale></error>'
