接口开发

import flask,pymysql
import hashlib
import json
server = flask.Flask(__name__) #把当前这个python文件当做一个服务

def my_db(sql,port=3306,charset='utf8'):
   ip, user, passwd, db = '10.24.31.40','jz','123456','jxz'
   coon = pymysql.connect(host=ip,user=user,
               password=passwd,db=db,
               port=port,charset=charset,autocommit=True)
   cur = coon.cursor()
   sql=sql.strip()
   cur.execute(sql)
   sql_start = sql[:6].lower()#取sql的开头,转成小写
   if sql_start.startswith('select') or sql_start.startswith('show'):
      data = cur.fetchall()
   else:
      data = 'ok'
   cur.close()
   coon.close()
   return data

def my_md5(s):
   m = hashlib.md5(s.encode())
   return m.hexdigest()

@server.route('/login',methods=['get','post'])
def taotao():
   username = flask.request.values.get('username')  #是从客户端发过来的数据
   pwd = flask.request.values.get('password')
   flask.request.cookies.get('xxx')  #获取cookie
   flask.request.headers.get('xxxx')  #获取headers
   json_data = flask.request.json.get('username') #这个获取入参是json类型的
   if username=='nhy' and pwd=='123456':
      res  = {'code':1000,'msg':'登录成功','sign':'sdfsdf23vsrqsdf'}
   else:
      res = {'code':2000,'msg':'账号/密码错误'}
   return json.dumps(res,ensure_ascii=False)
@server.route('/register',methods=['post'])
def reg():
   username = flask.request.values.get("username")
   passwd = flask.request.values.get("passwd")
   cpasswd = flask.request.values.get("cpasswd")
   if username and passwd and cpasswd:
      sql1 = 'select * from nhy where name="%s";'%username
      sql_res = my_db(sql1)
      if sql_res:
         res = {'code':2001,'msg':'该用户已经被注册'}
      else:
         if passwd==cpasswd:#
            md5_pwd = my_md5(passwd)
            sql2 = 'insert into nhy (name,pwd) value ("%s","%s");'%(username,md5_pwd)
            my_db(sql2)
            res = {'code':1000,'msg':'注册成功'}
         else:
            res = {'code':2003,'msg':'两次输入的密码不一致'}
   else:
      res = {'code':2002,'msg':'必填参数未填，请查看接口文档！'}
   return json.dumps(res,ensure_ascii=False)
server.run(port=8989,debug=True)  #启动服务

接下来，通过postman去测试所开发的接口。
