1.封装上传图片的函数

.def upload_image(pathName, pathRoute, pathType, keyName=None):    '''    :param pathName:   图片名称    :param pathRoute:  图片路径    :param pathType:   图片类型    :param keyName:    文件名称    :return:    '''    file = open(pathRoute, 'rb')    files = {            keyName: (pathName, file, pathType)    }    return files

2. 封装车牌号的函数

def chepaihao(len='6'):    char0 = '京津沪渝冀豫云辽黑湘皖鲁新苏浙赣鄂桂甘晋蒙陕吉闽赣粤青藏川宁琼'    char1 = 'ABCDEFGHJKLMNPQRSTUVWXYZ'  # 车牌号中没有I和O，可自行百度    char2 = '1234567890ABCDEFGHJKLMNPQRSTUVWXYZ'    char3 = '1234567890'    len0 = len(char0) - 1    len1 = len(char1) - 1    len2 = len(char2) - 1    len3 = len(char3) - 1    # while True:    code = ''    index0 = random.randint(1,len0)    index1 = random.randint(1, len1)    code += char0[index0]    code += char1[index1]    code += ' '    for i in ran## 标题ge(1, 5):        index2 = random.randint(1, len2)        code += char2[index2]    index3 = random.randint(1,len3)    code += char3[index3]    # test = re.match('^.\w.[A-Z]\d{4}$|^.\w.\d[A-Z]\d{3}$|^.\w.\d{2}[A-Z]\d{2}$|^.\w.\d{3}[A-Z]\d$|^.\w.\d{5}$',code)    print(code)    return code

3. 封装生成UUid 函数

# 生成UUiddef uuid_():    uid = uuid.uuid1()    return uid.hex

4. 封装连接数据库的函数

import pymysql# 获取连接方法def get_db_conn():    conn = pymysql.connect(host='地址',                           port=000, # 端口号                           user='name',                           passwd='23456',                           db='3454',  # 库名                           cursorclass=pymysql.cursors.DictCursor)    return conn# 封装数据库查询单条操作def query_db(sql):    conn = get_db_conn()          cur = conn.cursor()            cur.execute(sql)               conn.commit()    result = cur.fetchone()        cur.close()                    conn.close()                   return result# 封装数据库查询所有操作def query_all(sql):    conn = get_db_conn()           cur = conn.cursor()            cur.execute(sql)               conn.commit()    result = cur.fetchall()        cur.close()                    conn.close()                   return result# 封装更改数据库操作def change_db(sql):    conn = get_db_conn()      cur = conn.cursor()      try:        cur.execute(sql)          conn.commit()      except Exception as e:        conn.rollback()      finally:        cur.close()          conn.close()  # 封装数据库新增所有操作def insert_into(sql):    conn = get_db_conn()          cur = conn.cursor()            cur.execute(sql)             conn.commit()    result = cur.fetchall()        conn.close()                  return result
