如何将 html 文件作为附件添加到 python 中？

Question

matches = []
for root, dirnames, filenames in os.walk('C:\Users\Desktop\ADI\New folder'):
    for filename in fnmatch.filter(filenames, '*.html'):
        matches.append(os.path.join(root, filename))
        page = filename
        #print filename

        server.quit()

在上面的代码中：首先，我在目录中找到 *.html 文件。我正在找到它，它对我来说工作正常。稍后我想将该 html 文件作为电子邮件附件发送给某人。我在这方面失败了。有人可以建议我如何将文件附加到电子邮件并将其发送给相关人员吗？上面的程序在将电子邮件发送给此人时运行良好，它只是在电子邮件中打印文件的名称，但无法附加该电子邮件并发送它。

错误：

需要将文件内容附加到电子邮件数据。

例如

with open(fileToSend) as fp:
    attachment = MIMEText(fp.read(), _subtype=subtype)
attachment.add_header("Content-Disposition", "attachment",\
                      filename=os.path.basename(filename))

msg.attach(attachment)

在您的代码中执行以下操作（将 msg.attach(MIMEText(text)) 行替换为以下代码）：

ctype, encoding = mimetypes.guess_type(filename)
if ctype is None or encoding is not None:
    ctype = "application/octet-stream"
maintype, subtype = ctype.split("/", 1)

with open(filename) as fp:
    attachment = MIMEText(fp.read(), _subtype=subtype)
attachment.add_header("Content-Disposition", "attachment",\
                      filename=os.path.basename(filename))

msg.attach(attachment)

注意: filename 应该是我们要在电子邮件中附加的文件的完整路径。例如/var/opt/html/report_email.html

如果我添加多个收件人电子邮件 ID，则它不起作用。

if toaddress 是字符串，其中每个电子邮件 ID 用逗号分隔，即 , 例如"abc@gmail.com,xyz@gmail.com" 然后喜欢 server.sendmail(fromaddress,toaddress.split(','),msg.as_string())
