在網(wǎng)站開發(fā)的時(shí)候,常常需要生成一個(gè)唯一的的會(huì)話(session)id,這個(gè)會(huì)話 id 存儲(chǔ)在 cookie 中或者在其它安全的地方。:
create a unique session id
input - string to use as part of the data used to create the session key.
Although not required, it is best if this includes some unique
data from the site, such as it's IP address or other environment
information. For ZOPE applications, pass in the entire ZOPE "REQUEST"
object.
def makeSessionId(st):
import md5, time, base64, string
m = md5.new()
m.update('this is a test of the emergency broadcasting system')
m.update(str(time.time()))
m.update(str(st))
return string.replace(base64.encodestring(m.digest())[:-3], '/', '/span>)
def makeSessionId_nostring(st):
import md5, time, base64
m = md5.new()
m.update('this is a test of the emergency broadcasting system')
m.update(str(time.time()))
m.update(str(st))
return base64.encodestring(m.digest())[:-3].replace('/', '/span>)
輸入?yún)?shù):st,不限制 st 唯一,但是建議傳入的 st 是唯一的,可以是 IP 或者一些環(huán)境信息。 輸出:唯一的 session id 字符串。
