解析电子邮件正文

Question

I'm using the gmail API to parse through my gmail message body. It works other than when the body is in an html. Does anyone know how I can just extract the text within the email? If not, how I can just ignore emails with html?

Eventually I want to implement this for personal/professional emails in which there likely won't be html in it.

def message_converter(message_id):
        message = service.users().messages().get(userId='me', id=message_id,format='raw').execute()
        msg_str = str(base64.urlsafe_b64decode(message['raw'].encode('ASCII')),'UTF-8')
        mime_msg = email.message_from_string(msg_str)
        if mime_msg.is_multipart():
            for payload in mime_msg.get_payload():
                # if payload.is_multipart(): ...
                print (payload.get_payload())
        else:
            print (mime_msg.get_payload())

Answer 1

html2text does a pretty good job - it converts HTML into ASCII text.

You may need to do additional parsing/formatting after the fact, however.

Answer 2

i dont know if this can help you but Gmail Api have the same syntax so in C# you can find the text message in 3 places (it depends on the mail server) so :

msg.Payload.Parts[1].Body.Data;  // here you can find text message without HTML tag

msg.Payload.Parts[0].Body.Data; // here you can find text message with HTML tag

msg.Payload.Body.Data; // and here you dont have a choice you have the HTMl tag

This answer may help you do what you are heading to. I understand that you wanna get certain texts out of the body of the email. You may use regular expressions to do that. I made a video explaining how to get data out of Gmail email body but using Google App Script (JavaScript):
