Python 'RFC822‘- IMAPClient用于Gmail

Question

因此，我是一个编码初学者，我选择了Python开始。我试图把一个脚本，以获得最后一封电子邮件从一个特定的联系人收到的“日期”。这个“日期”将保存在谷歌的表格中。

下面是我到目前为止只处理Gmail部分的代码。我实际上使用了来自here的部分代码。但是，我收到了一个错误

跟踪(最近一次调用)：文件"C:/Users/PycharmProjects/Automate/Code.py"，第33行，在msg_string =data‘RFC822 822’KeyError：'RFC822‘中

不知道出了什么问题。我正在使用Python3.8.1

import email
from imapclient import IMAPClient

HOST = 'imap.gmail.com'
USERNAME = 'username'
PASSWORD = 'password'
ssl = True

## Connect, login and select the INBOX
server = IMAPClient(HOST, use_uid=True, ssl=ssl)
server.login(USERNAME, PASSWORD)
select_info = server.select_folder('INBOX')

messages = server.search(['FROM', 'email_of_the_contact@gmail.com'])

response = server.fetch(messages, ['RFC822'])

for msgid, data in response.items():
    msg_string = data['RFC822']
    msg = email.message_from_string(msg_string)
    print('ID %d: From: %s Date: %s' % (msgid, msg['From'], msg['date']))

此外，也不确定代码是否完成了我想要达到的目标。任何帮助都很感激。

另外，添加从调试获得的消息。

在这里，我运行了您的代码，以重新生成相同的错误，我得到了同样的。

为了解决这个问题，我检查了dict键，并注意到dict键和值被编码为字节。

因此，我使用字节键访问并解码将消息转换为str，如下所示：

import email
from imapclient import IMAPClient

HOST = 'imap.gmail.com'
USERNAME = 'username'
PASSWORD = 'password'
ssl = True

## Connect, login and select the INBOX
server = IMAPClient(HOST, use_uid=True, ssl=ssl)
server.login(USERNAME, PASSWORD)
select_info = server.select_folder('INBOX')

messages = server.search(['FROM', 'email_of_the_contact@gmail.com'])

response = server.fetch(messages, ['RFC822'])

for msgid, data in response.items():
    msg_string = data[b'RFC822']
    msg = email.message_from_string(msg_string.decode())
    print('ID %d: From: %s Date: %s' % (msgid, msg['From'], msg['date']))
