ValueError: too many values to unpack (Python 2.7)
提问by Ionu?
values = data.split("\x00")
username, passwordHash, startRoom, originUrl, bs64encode = values
if len(passwordHash)!= 0 and len(passwordHash)!= 64:
passwordHash = ""
if passwordHash != "":
passwordHash = hashlib.sha512(passwordHash).hexdigest()
username = username.replace("<", "")
if len(startRoom) > 200:
startRoom = ""
startRoom = self.roomNameStrip(startRoom, "2").replace("<","").replace("&#", "&amp;#")
self.login(username, passwordHash, startRoom, originUrl)
Error:
username, passwordHash, startRoom, originUrl, bs64encode = values
ValueError: too many values to unpack

Check the output of
检查输出
print len(values)
It has more than 5 values (which is the number of variables you are trying to "unpack" it to) which is causing your "too many values to unpack" error:
它有 5 个以上的值（这是您尝试将其“解包”到的变量数），这会导致“解包的值太多”错误：
username, passwordHash, startRoom, originUrl, bs64encode = values
If you want to ignore the tail end elements of your list, you can do the following:
如果要忽略列表的尾端元素，可以执行以下操作：
#assuming values has a length of 6
username, passwordHash, startRoom, originUrl, bs64encode, _ = values
or unpack only the first 5 elements (thanks to @JoelCornett)
或仅解压前 5 个元素（感谢 @JoelCornett）
#get the first 5 elements from the list
username, passwordHash, startRoom, originUrl, bs64encode = values[:5]

When you're doing values = data.split("\x00")it's producing more then 5 elements, probably not all values are separated by \x00.
当您这样做时，values = data.split("\x00")它会产生超过 5 个元素，可能并非所有值都由\x00.
Inspect the value of valueswith print valuesand check it's size with len(values)
检查valueswith的值print values并检查它的大小len(values)
