MySQL报错113_连接 MySQL 报错'NoneType' object has no attribute '__getitem_

新手一枚，想批量获取一批数据在后台自动生成的 ID 然后做匹配

本来是 for 循环，报错后拆开来还是报错那应该不是我循环的问题了

第一段能正常获取到 ID ，为什么第二段始终返回 NONE

Traceback (most recent call last):

File "add_store.py", line 119, in

main()

File "add_store.py", line 113, in main

print result[0]

TypeError: 'NoneType' object has no attribute '__getitem__'

代码如下：

(删掉了括号里的敏感信息)

hosturl =

posturl =

posturl2 =

cj = cookielib.LWPCookieJar()

cookie_support = urllib2.HTTPCookieProcessor(cj)

opener = urllib2.build_opener(cookie_support, urllib2.HTTPHandler)

urllib2.install_opener(opener)

h = urllib2.urlopen(hosturl)

headers = {}

postData = {}

postData = urllib.urlencode(postData)

request = urllib2.Request(posturl, postData, headers)

response = urllib2.urlopen(request)

conn = MySQLdb.connect()

def main():

i = 31

stname = 'teststore' + str(i)

postData2 = {'storeName': stname}

postData2 = urllib.urlencode(postData2)

request2 = urllib2.Request(posturl2, postData2, headers)

response2 = urllib2.urlopen(request2)

cur = conn.cursor()

cur.execute("select a.store_id from store as a where a.store_name = %s", [stname])

print stname

result = cur.fetchone()

print result[0]

i = 32

stname = 'teststore' + str(i)

postData2 = {'storeName': stname}

postData2 = urllib.urlencode(postData2)

request2 = urllib2.Request(posturl2, postData2, headers)

response2 = urllib2.urlopen(request2)

cur.execute("select a.store_id from store as a where a.store_name = %s", [stname])

print stname

result = cur.fetchone()

print result[0]

cur.close()

conn.close()

if __name__ == '__main__':

main()
