我需要帮助发送从内存邮件枪excel附件

Question

我试图用Python和mailgunrestapi发送一封带有Excel附件的电子邮件。你知道吗

其思想是使用openpyxl创建excel文件，然后将存储在python内存中的excel工作簿作为附件发送。你知道吗

非常感谢

import workbook from openpyxl
from openpyxl import Workbook

wb = Workbook()

ws = wb.active

ws['A1'] = 42

def send_simple_message(wb):
  return requests.post(
    "https://api.mailgun.net/v3/sandboxf04fcce3c4dc46c987c92f3a967e7f9c.mailgun.org/messages",
    files = [("attachment", ("test.xlsx", wb))],
    auth = ("api", "3701ba6d2b1ad202e76a4322a80c7600-87cdd4445-897e02b1"),
    data = {
      "from": "Excited User <mailgun@sandboxf04brede3c4dc46c987c92f3a967e7f9c.mailgun.org>",
      "to": "exampleemail@gmail.com",
      "subject": "Hello",
      "text": 'hello'
    })

send_simple_message(wb)

它导致了以下回溯错误：

 File "<ipython-input-39-5dc97cf501dc>", line 1, in <module>
    send_simple_message(wb)

  File "<ipython-input-37-fc3ec9cbb304>", line 9, in send_simple_message
    "text": 'hello'})

  File "/Users/willpeebles/anaconda/lib/python3.5/site-packages/requests/api.py", line 112, in post
    return request('post', url, data=data, json=json, **kwargs)

  File "/Users/willpeebles/anaconda/lib/python3.5/site-packages/requests/api.py", line 58, in request
    return session.request(method=method, url=url, **kwargs)

  File "/Users/willpeebles/anaconda/lib/python3.5/site-packages/requests/sessions.py", line 504, in request
    prep = self.prepare_request(req)

  File "/Users/willpeebles/anaconda/lib/python3.5/site-packages/requests/sessions.py", line 436, in prepare_request
    hooks=merge_hooks(request.hooks, self.hooks),

  File "/Users/willpeebles/anaconda/lib/python3.5/site-packages/requests/models.py", line 305, in prepare
    self.prepare_body(data, files, json)

  File "/Users/willpeebles/anaconda/lib/python3.5/site-packages/requests/models.py", line 499, in prepare_body
    (body, content_type) = self._encode_files(files, data)

  File "/Users/willpeebles/anaconda/lib/python3.5/site-packages/requests/models.py", line 158, in _encode_files
    fdata = fp.read()

AttributeError: 'Workbook' object has no attribute 'read'

我该如何更改代码？你知道吗

工作簿不是类似文件的对象。请求的文件需要类似文件的对象，因此需要先将工作簿转换为类似文件的对象。你可以用拜特西奥要创建类似内存文件的对象，请执行以下操作：

from io import BytesIO

...

bio = BytesIO()
wb.save(bio)
bio.seek(0)
send_simple_message(bio)
