我正在制作一个Tkinter应用程序来发送一封简短的电子邮件。Tkinter StringVar发送邮件错误SMTPlib
代码全:
from Tkinter import *
from smtplib import *
from time import sleep
root=Tk()
root.wm_title("Gmail short message sender")
w = 500 # width for the Tk root
h = 500 # height for the Tk root
# get screen width and height
ws = root.winfo_screenwidth() # width of the screen
hs = root.winfo_screenheight() # height of the screen
# calculate x and y coordinates for the Tk root window
x = (ws/2) - (w/2)
y = (hs/2) - (h/2)
# set the dimensions of the screen
# and where it is placed
root.geometry('%dx%d+%d+%d' % (w, h, x, y))
def send():
e1_var.get()
e2_var.get()
e3_var.get()
try:
smtpObj = SMTP('smtp.gmail.com', "587")
smtpObj.ehlo()
smtpObj.starttls()
smtpObj.ehlo()
smtpObj.login("[email protected]", "password")
smtpObj.sendmail(sender1, receivers1, msg1)
l1=Label(text="Sent").grid()
sleep(1)
l1.destroy()
except SMTPException:
l2=Label(text="Error").grid()
raise
e1_var=StringVar()
e2_var=StringVar()
e3_var=StringVar()
sender = e1_var
receivers = [e2_var]
msg = e3_var
sender1 = '%s' % (sender)
receivers1 = '[%s]'% (receivers)
msg1 = '%s' % (msg)
e1=Entry(root, textvariable=e1_var).grid()
e2=Entry(root, textvariable=e2_var).grid()
e3=Entry(root, textvariable=e3_var).grid()
b1=Button(text="Send", command=send).grid()
root.mainloop()
问题:
问题是与我StringVar
实例。首先,StringVar
实例正在绘制此错误。
Exception in Tkinter callback
Traceback (most recent call last):
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk/Tkinter.py", line 1536, in __call__
return self.func(*args)
File "Desktop/Python Scripts/Email.py", line 32, in send
smtpObj.sendmail(sender1, receivers1, msg1)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/smtplib.py", line 724, in sendmail
esmtp_opts.append("size=%d" % len(msg))
AttributeError: StringVar instance has no attribute '__len__'
但我通过增加这部分解决了这个问题,
sender1 = sender
receivers1 = receivers
msg1 = msg
和不断变化的smtpObj.sendmail(sender, receivers, msg)
到smtpObj.sendmail(sender1, receivers1, msg1)
。我现在得到这个错误。

这是一个语法错误,因为引号?如果是这样,我该如何解决第一个错误?
那么我的代码是什么样的呢? –
