我正在嘗試使用 Django 中的 Sendgrid 動態模板發送批量電子郵件并收到此錯誤：The personalizations field is required and must have at least one personalization.
使用sendgrid 6.9.7
有誰看到我可能出錯的地方：
from django.conf import settings
from sendgrid import SendGridAPIClient
from sendgrid.helpers.mail import Mail, To
def send_mass_email():
to_emails = [
To(email='[email protected]',
dynamic_template_data={
"thing_i_want_personalized": 'hello email 1',
}),
To(email='[email protected]',
dynamic_template_data={
"thing_i_want_personalized": 'hello email 2',
}),
]
msg = Mail(
from_email='[email protected]>',
)
msg.to_emails = to_emails
msg.is_multiple = True
msg.template_id = "d-template_id"
try:
sendgrid_client = SendGridAPIClient(settings.SENDGRID_API_KEY)
response = sendgrid_client.send(msg)
print(response.status_code)
print(response.body)
print(response.headers)
except Exception as e:
print(e)
print(e.body)
return
輸出是
HTTP Error 400: Bad Request
b'{"errors":[{"message":"The personalizations field is required and must have at least one personalization.","field":"personalizations","help":"http://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#-Personalizations-Errors"}]}'
uj5u.com熱心網友回復：
該類Mail在初始化期間使用初始值做了一些事情（它基于 設定私有內部值to_emails），因此您需要在初始化程式中傳遞to_emails和is_multiple而不是稍后：
from django.conf import settings
from sendgrid import SendGridAPIClient
from sendgrid.helpers.mail import Mail, To
def send_mass_email():
to_emails = [
To(email='[email protected]',
dynamic_template_data={
"thing_i_want_personalized": 'hello email 1',
}),
To(email='[email protected]',
dynamic_template_data={
"thing_i_want_personalized": 'hello email 2',
}),
]
msg = Mail(
from_email='[email protected]>',
to_emails = to_emails,
is_multiple = True
)
msg.template_id = "d-template_id"
try:
sendgrid_client = SendGridAPIClient(settings.SENDGRID_API_KEY)
response = sendgrid_client.send(msg)
print(response.status_code)
print(response.body)
print(response.headers)
except Exception as e:
print(e)
print(e.body)
return
