Gmail API -看到奇怪的德语字符使用'raw‘输出并解码为utf-8

import base64
from email import message_from_bytes

def decode_raw_message(raw_message):
    # 将'raw'消息进行base64解码
    decoded_message = base64.urlsafe_b64decode(raw_message)

    # 使用email库解析解码后的消息
    parsed_message = message_from_bytes(decoded_message)

    # 获取邮件的文本内容
    text_content = ""
    if parsed_message.is_multipart():
        for part in parsed_message.get_payload():
            if part.get_content_type() == "text/plain":
                text_content = part.get_payload(decode=True).decode("utf-8")
                break
    else:
        text_content = parsed_message.get_payload(decode=True).decode("utf-8")

    return text_content

# 示例用法
raw_message = "这里填入你的'raw'消息"
decoded_text = decode_raw_message(raw_message)
print(decoded_text)
