import flask,json
from tools123 import op_mysql  #op_mysql()
#import tools # tools123.op_mysql    这种方式也可以调用函数
# 接口，后台服务
server = flask.Flask(__name__) #把咱们这个app这个python文件当做一个server
@server.route(‘/get_user‘,methods=[‘get‘,‘post‘])#server.route()是装饰器，直接变成接口
def get_all_user():
   sql = ‘select * from bt_stu;‘
   res = op_mysql(
      host=‘211.149.218.16‘,
      user=‘jxz‘, password=‘123456‘,  # port这里一定要写int类型
      port=3306, db=‘jxz‘, charset=‘utf8‘, sql=sql)
   response = json.dumps(res,ensure_ascii=False) #把list转成json
   return response #return 的时候只能return字符串

@server.route(‘/add_user‘,methods=[‘post‘])
def add_user():
   user_id = flask.request.values.get(‘id‘)  #这里的参数就是调用接口的时候传入的参数
   username = flask.request.values.get(‘u‘) #
   if user_id and username:
      sql = "insert into stu values (‘%s‘,‘%s‘);"%(user_id,username)
      res = op_mysql(
         host=‘211.149.218.16‘,
         user=‘jxz‘, password=‘123456‘,  # port这里一定要写int类型
         port=3306, db=‘jxz‘, charset=‘utf8‘, sql=sql)
      response = {‘code‘:308,‘msg‘:‘添加成功‘}
   else:
      response = {‘code‘:503,‘msg‘:‘必填参数未填！‘}
   return json.dumps(response,ensure_ascii=False)


server.run(port=8080,debug=True)
