AttributeError: 'SendGridAPIClient' object has no attribute 'send'

Question

我正在使用 sendgrid 通过 django 发送邮件，但是，它一直说 AttributeError: 'SendGridAPIClient' object has no attribute 'send'

重现步骤

1. 安装发送网格 pip install sendgrid
2. 运行 脚本

from sendgrid import SendGridAPIClient
from sendgrid.helpers.mail import Mail

sg = SendGridAPIClient("the_api_key")

email_data = Mail(
    from_email="support@email.africa",
    to_email="example@email.com",
    subject="YOUR EVENT IS NOW LIVE ON SITE!",
)
email_data.dynamic_template_data = json.dumps({
    "username": "example username",
    "item_name": "example item name",
    "item_slug": "path to example item slug",
    "template_id": "transactional template id",
    "message_type": "EMAIL"
})

response = sg.send(request_body=email_data.get())

错误：

Answer 1

我来回答我自己。

问题出在 sendgrid 版本上。 sendgrid version 3.6.5中的SendGridAPIClient没有任何方法send()。

这是不使用 mail 助手的解决方案：

sg = sendgrid.SendGridAPIClient(apikey="THE_SENDGRID_API_KEY")
data = {
    "personalizations": [
        {
            "to": [
                {
                    "email": "example@email.com"
                }
            ],
            "dynamic_template_data": {
                "subject": "YOUR EVENT IS NOW LIVE ON SITE!",
                "username": user_name,
                "item_name": item_name,
                "item_slug": item_slug,
            },

        }
    ],
    "from": {
        "email": "support@email.africa"
    },
    "template_id": "the_template_id",
}

response = sg.client.mail.send.post(request_body=data)

这是使用 mail 助手的解决方案：

from sendgrid import SendGridAPIClient
from sendgrid.helpers.mail import Mail, Substitution

sg = SendGridAPIClient("the_api_key")

email_data = Mail(
    to_email="example@email.com",
)
email_data.add_personalization(personalization[0].Substitution({
    "username": "example username",
    "item_name": "example item name",
    "item_slug": "path to example item slug"
}))
email_data.set_from("support@email.africa")
email_data.set_subject("YOUR EVENT IS NOW LIVE ON SITE!")
email_data.set_template_id("the_template_id")

response = sg.client.mail.send.post(request_body=email_data.get())
