def send_complex_message():
return requests.post(
"https://api.mailgun.net/v2/samples.mailgun.org/messages",
auth=("api", "key-3ax6xnjp29jd6fds4gc373sgvjxteol0"),
files=MultiDict([("attachment", open("files/test.jpg")),
("attachment", open("files/test.txt"))]),
data={"from": "Excited User <[email protected]>",
"to": "[email protected]",
"cc": "[email protected]",
"bcc": "[email protected]",
"subject": "Hello",
"text": "Testing some Mailgun awesomness!",
"html": "<html>HTML version of the body</html>"})
This isn't working for me. When the email arrives, it only has one attachment. I'm using the MultiDict object in python-bottle. I broke out just the files dictionary so I could examine it as follows:
files=MultiDict([("attachment", ("file1.txt", "text file 1"),
("attachment", ("file2.txt", "text file 2")])
When you do files.values(), it only has one entry "file2.txt." This makes sense. I see the same behavior if I attempt to append() an entry as well. if the "Key" is the same ("attachment" in this case) it overwrites the existing record.
If I give it unique keys like attachment-1, and attachment-2, the API accepts the post, however the mail is delivered with no attachments.
So I guess my questions are:
1) Is there a difference in the MultiDict object in bottle which is causing this to fail? It would seem having multiple entries in a dictionary with the same key wouldn't be allowed?
2) Is there something undocumented I should be doing to submit multiple files to mailgun? or is it impossible to do so?

You can actually use a list of tuples in the file param and eliminate the need for Multidict. Here's what it would look like:
import requests
print requests.post("https://api.mailgun.net/v2/samples.mailgun.org/messages",
auth=("api", "key-3ax6xnjp29jd6fds4gc373sgvjxteol0"),
files=[("attachment", open("files/test.jpg")),
("attachment", open("files/test.txt"))],
data={"from": "Excited User <[email protected]>",
"to": "[email protected]",
"cc": "[email protected]",
"bcc": "[email protected]",
"subject": "Hello",
"text": "Testing some Mailgun awesomness!",
"html": "<html>HTML version of the body</html>"})

I know this is already answered, however, I thought I'd post how I got this working with multiple attachments.
Here is my python function, the attachments parameter is a list of file paths.
import requests
def send_complex_message(to, email_from, subject, html_body, attachments=None):
'''
to, email_from, subject, and html_body should be self explanatory.
attachments is a list of file paths, like this:
['/tmp/tmp5paoks/image001.png','/tmp/tmp5paoks/test.txt']
'''
data={"from": email_from,
"to": [to,""],
"subject": subject,
"html": html_body}
files = None
if attachments:
files = {}
count=0
for attachment in attachments:
with open(attachment,'rb') as f:
files['attachment['+str(count)+']'] = (os.path.basename(attachment), f.read())
count = count+1
return requests.post("https://api.mailgun.net/v2/mydomain.com/messages",
auth=(USER, PASSWORD),
files=files,
data=data)
I know it is a little verbose, however, it is working :-) .
I got the idea on how to build the files dictionary from here: https://gist.github.com/adamlj/8576660
