Question

任何人都请帮助，我起诉sendgrid V3 API。但我无法找到任何方式来发送邮件给多个收件人。预先感谢。

    from sendgrid.helpers.mail import *

    sg = sendgrid.SendGridAPIClient(apikey="SG.xxxxxxxx")
    from_email = Email("FROM EMAIL ADDRESS")
    to_email = Email("TO EMAIL ADDRESS")
    subject = "Sending with SendGrid is Fun"
    content = Content("text/plain", "and easy to do anywhere, even with Python")
    mail = Mail(from_email, subject, to_email, content)
    response = sg.client.mail.send.post(request_body=mail.get())
    print(response.status_code)
    print(response.body)
    print(response.headers)

我想发送电子邮件给多个收件人。像to_mail = “[email protected]，[email protected]”。

发送电子邮件给多recicpent在sendgrid V3。

        import time

        import os

        print "Send email to multiple user"

        sg = sendgrid.SendGridAPIClient(apikey='your sendrid key here')
        data = {
        "personalizations": [

        }
        response = sg.client.mail.send.post(request_body=data)
        print(response.status_code)
        if response.status_code == 202:
            print "email sent"

基于Subhrajyoti达斯的答案，我写了下面的代码，也就是将电子邮件发送到多个收件人的mail_example.py实例的简化版本。

def SendEmail():
    sg = sendgrid.SendGridAPIClient(api_key="YOUR KEY")
    from_email = Email ("FROM EMAIL ADDRESS")

    to_list = Personalization()
    to_list.add_to (Email ("EMAIL ADDRESS 1"))
    to_list.add_to (Email ("EMAIL ADDRESS 2"))
    to_list.add_to (Email ("EMAIL ADDRESS 3"))

    subject = "EMAIL SUBJECT"
    content = Content ("text/plain", "EMAIL BODY")
    mail = Mail (from_email, subject, None, content)
    mail.add_personalization (to_list)
    response = sg.client.mail.send.post (request_body=mail.get())

    return response.status_code == 202

Answer 3

您可以在下面的方式更新代码。你可以找到目前在Sendgrid的包mail_example.py相同。

personalization = get_mock_personalization_dict()
mail.add_personalization(build_personalization(personalization))

def get_mock_personalization_dict():
    """Get a dict of personalization mock."""
    mock_pers = dict()
    mock_pers['to_list'] = [Email("[email protected]",
                              "Example User"),
                            Email("[email protected]",
                              "Example User")]
    return mock_pers

def build_personalization(personalization):
    """Build personalization mock instance from a mock dict"""
    mock_personalization = Personalization()
    for to_addr in personalization['to_list']:
        mock_personalization.add_to(to_addr)
    return mock_personalization

请注意，与其他的答案的代码在这里，电子邮件的收件人将看到每个人在电子邮件地址字段。为了避免这其中有使用单独的Personalization对象每一个电子邮件地址：

def SendEmail():
    sg = sendgrid.SendGridAPIClient(api_key="YOUR KEY")
    from_email = Email ("FROM EMAIL ADDRESS")

    person1 = Personalization()
    person1.add_to(Email ("EMAIL ADDRESS 1"))
    person2 = Personalization()
    person2.add_to(Email ("EMAIL ADDRESS 2"))

    subject = "EMAIL SUBJECT"
    content = Content ("text/plain", "EMAIL BODY")
    mail = Mail (from_email, subject, None, content)
    mail.add_personalization(person1)
    mail.add_personalization(person2)
    response = sg.client.mail.send.post (request_body=mail.get())

    return response.status_code == 202
