python自动从本地foxmail中获取某一主题的读取_用Python读取Foxmail导出的邮件

下面是一个示例代码，可以实现自动从本地Foxmail中获取某一主题的邮件：

import os
import email
import codecs

def get_mail_by_subject(subject):
    """
    根据主题获取邮件
    """
    mail_dir = 'Foxmail邮件存储路径'
    for root, dirs, files in os.walk(mail_dir):
        for file_name in files:
            if file_name.endswith('.eml'):
                file_path = os.path.join(root, file_name)
                with open(file_path, 'rb') as f:
                    content = f.read()
                try:
                    msg = email.message_from_bytes(content)
                    if msg['Subject'] == subject:
                        return read_foxmail_eml(file_path)
                except:
                    pass

def read_foxmail_eml(eml_path):
    """
    读取Foxmail导出的.eml文件
    """
    with open(eml_path, 'rb') as f:
        content = f.read()
    msg = email.message_from_bytes(content)

    subject = msg['Subject']
    from_address = msg['From']
    to_address = msg['To']
    date = msg['Date']
    body = msg.get_payload(decode=True).decode()

    # 处理HTML格式的正文
    if msg.is_multipart():
        for part in msg.walk():
            content_type = part.get_content_type()
            filename = part.get_filename()
            if content_type == 'text/html':
                body = part.get_payload(decode=True).decode()
    else:
        content_type = msg.get_content_type()
        if content_type == 'text/html':
            body = msg.get_payload(decode=True).decode()

    # 处理附件
    attachments = []
    if msg.is_multipart():
        for part in msg.walk():
            content_type = part.get_content_type()
            filename = part.get_filename()
            if filename:
                filename = decode_str(filename)
                data = part.get_payload(decode=True)
                attachment = {'filename': filename, 'data': data}
                attachments.append(attachment)

    result = {'from': from_address, 'to': to_address, 'subject': subject, 'date': date, 'body': body, 'attachments': attachments}
    return result

def decode_str(s):
    """
    解码字符串
    """
    value, charset = email.header.decode_header(s)[0]
    if charset:
        value = value.decode(charset)
    return value

if __name__ == '__main__':
    # 测试代码
    subject = '测试邮件主题'
    result = get_mail_by_subject(subject)
    print(result)

你只需要将 `mail_dir` 改为你本地Foxmail邮件存储路径，将 `subject` 改为你要查找的邮件主题，运行代码即可自动获取该主题的邮件内容。
