我正在编写Python代码，它将在Excel文件中添加一个字符串，并将该文件附加到电子邮件中。我使用 AWS SES 发送此电子邮件。
当我尝试运行代码时，出现以下错误 -
TypeError: expected bytes-like object, not Workbook
下面是我的代码-
import boto3
import xlsxwriter
from email.mime.text import MIMEText
from email.mime.application import MIMEApplication
from email.mime.multipart import MIMEMultipart
def lambda_handler(event, context):
client = boto3.client('ses',region_name=AWS_REGION)
sender = "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="9ae2e2e2dafdf7fbf3f6b4f9f5f7" rel="noreferrer noopener nofollow">[email protected]</a>"
to = "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="35545454755258545c591b565a58" rel="noreferrer noopener nofollow">[email protected]</a>"
workbook = xlsxwriter.Workbook('abc.xlsx')
worksheet = workbook.add_worksheet()
worksheet.write('A1', 'Hello..')
#send email with attachment
msg = MIMEMultipart()
msg['Subject'] = 'Test Email'
msg['From'] = sender
msg['To'] = to
body_text = MIMEText(BODY_TEXT, "html")
attachment = MIMEApplication(workbook)
attachment.add_header('Content-Disposition', 'attachment', filename='Expenses01.xlsx')
msg.attach(attachment)
msg.attach(body_text)
response = client.send_raw_email(
Source=sender,
Destinations=[to],
RawMessage={"Data": msg.as_string()}
)
我知道工作簿对象有问题。但我不知道如何解决这个问题。有人可以帮我吗？
最佳答案
阅读 XLSXWriter 文档后，我找到了答案。链接-https://xlsxwriter.readthedocs.io/workbook.html
我发布这个答案，以便它可以帮助像我这样的其他新的Python开发人员。 早期的 MIMEApplication() 不接受工作簿对象，因此我们需要对其进行转换。我已经更新了我的代码。我使用 BytesIO 创建 Workbook 对象，然后将该对象添加到 MIMEApplication()。此示例将创建 Excel 文件并将该文件附加到电子邮件中。 新代码-
from io import BytesIO
output = BytesIO()
workbook = xlsxwriter.Workbook(output)
worksheet = workbook.add_worksheet()
worksheet.write('A1', 'Hello..')
attachment = MIMEApplication(output.getvalue())
attachment.add_header('Content-Disposition', 'attachment', filename='abc.xlsx')
attachment.add_header('Content-Type', 'application/vnd.ms-excel; charset=UTF-8')
关于excel - 无法使用 python 将 Excel 文件附加到电子邮件 - TypeError : expected bytes-like object, 不是工作簿，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58803820/
