我们无法从代码中看出您发布的
self.data()
正在做什么,但从您的错误中可以清楚地看出,它返回的是None
。如果尝试不解包,则会得到以下结果:
def data(self, msg):
self.putcmd("data")
(code, repl) = self.getreply()
if self.debuglevel > 0:
print>>stderr, "data:", (code, repl)
if code != 354:
#raise SMTPDataError(code, repl)
print "Err"
else:
q = quotedata(msg)
if q[-2:] != CRLF:
q = q + CRLF
q = q + "." + CRLF
self.send(q)
(code, msg) = self.getreply()
if self.debuglevel > 0:
print>>stderr, "data:", (code, msg)
return (code, msg)
如果得到代码354,则注释掉了
raise
,函数现在返回None。这也可能是问题所在。self.data里面是什么?我猜self.data是一个方法,它缺少一个return语句。但这只是一个猜测。。。
>>> (code, resp) = None
