Day8：接口开发

一、写日志

log.debug('xxx值是什么')
log.info('调用了什么xxx')
log.warning('xxx警告！')
log.error('xxx值是什么')

import nnlog
log = nnlog.Logger('book_server.log',when='D',backCount=3)   #when 没分、每秒每天、产生的back..保留5天的日志

二、发送网络请求

import requests
url = '127.0.0.1:8999/api/login'
data = {'username':'testuser1','passwd':'111111'}
r = requests.get(url,params=data)  #发请求  get
r = requests.post(url,data=data)  #如果url和内容里都要写参数，那就要写pararms



print(r.text) #结果返回的就是字符串
print(r.json())# 结果返回的就是字典，必须返回的是json，才能转成字典

　三、上传文件

r = requests.post(url,data = {'session_id':'6ab8785039dcf50fb11c53acc1db7648'}),
                files = {'file_name':open('account.xls','rb')

　四、发送邮件

import yagmail
username = '[email protected]'
password = 'rsbzhzrwyayoiffh'   #生成授权码，qq，163,126 都是授权码，公司自己的邮箱用密码就行
mail_server = 'smtp.qq.com'

m=yagmail.SMTP(user=username,password=password,host=mail_server,
             smtp_ssl=True)  #如果邮箱使用的安全协议就需要加这个，qq邮箱就是使用了安全协议

to = '[email protected]'
cc = ['[email protected]']

m .send(to = to, cc=cc,subject='今天天气怎么样',contents='今天怎么样',attachments=r'发送邮件.py')

　五、接口开发之session实现

import flask
import tools
import json,redis
import random

server = flask.Flask(__name__)
#新建一个服务，把当前这个python文件当做一个服务

ip = '118.24.3.40'
password='HK139bc&*'
r = redis.Redis(host=ip,password=password,port=6379,db=10,
                decode_responses=True)#连接redis

@server.route('/login',methods=['get'])
def hello():
    uname = flask.request.values.get('username')
    pd = flask.request.values.get('passwd')
    # sql = 'select * from app_myuser where username="%s"'%uname
    # res = tools.my_db(sql)
    key='nhy:%s'%uname
    res = r.get(key)
    if res:
        res = json.loads(res)
        if tools.my_md5(pd) == res.get('passwd'):
            res = {"code":0,"msg":"登录成功！"}
        else:
            res = {"code":1,"msg":"密码错误！"}
    else:
        res = {'code':2,"msg":"用户不存在"}
    return json.dumps(res,ensure_ascii=False,indent=4)
@server.route('/reg',methods=['post'])
def reg():
    uname = flask.request.values.get('username')
    pd = flask.request.values.get('passwd')
    cpd = flask.request.values.get('cpwd')
    key='nhy:%s'%uname
    res = r.get(key)
    if res:
        res = {'code': 2, "msg": "用户已存在"}
    else:
        md5_password  = tools.my_md5(pd)
        res = {'id':random.randint(100,9999),'username':uname,'passwd':md5_password,'is_admin':1}
        r.set('nhy:%s'%uname,json.dumps(res))#
        res = {"code":0,"msg":"注册成功！"}
    return json.dumps(res,ensure_ascii=False,indent=4)

@server.route('/api/stu')
def get_stu():
    sql = 'select * from app_student'
    res = tools.my_db2(sql)
    return json.dumps(res)
