Postman的核心功能定位
Postman是一款专注于API开发与测试的工具,本身不具备直接发送邮件的能力。若需通过Postman实现邮件发送及收件人添加,需借助外部邮件服务API(如SendGrid、Mailgun等)或脚本程序,通过HTTP请求触发邮件发送流程。
若需通过Postman向单个收件人发送邮件,需按以下步骤配置HTTP请求(以常见邮件服务API为例):
https://api.sendgrid.com/v3/mail/send,需替换为实际服务地址)。Content-Type: application/json(指定请求体为JSON格式),以及邮件服务要求的认证头(如SendGrid的Authorization: Bearer YOUR_API_KEY)。{
"personalizations": [{"to": [{"email": "recipient@example.com"}]}],
"from": {"email": "sender@example.com"},
"subject": "Test Email",
"content": [{"type": "text/plain", "value": "This is a test email for a single recipient."}]
}
其中,"to"字段的"email"值为收件人邮箱地址,可根据需求修改。若需添加多个收件人,需根据邮件服务API的要求调整请求体中的收件人字段格式:
"personalizations"数组中添加多个"to"对象,例如:{
"personalizations": [
{"to": [{"email": "recipient1@example.com"}, {"email": "recipient2@example.com"}]},
{"to": [{"email": "recipient3@example.com"}]}
],
"from": {"email": "sender@example.com"},
"subject": "Test Email for Multiple Recipients",
"content": [{"type": "text/plain", "value": "This email is sent to multiple recipients."}]
}
上述配置会将邮件发送给recipient1@example.com、recipient2@example.com和recipient3@example.com三个收件人。requests库循环发送请求:import requests
from concurrent.futures import ThreadPoolExecutor
def send_email(recipient, subject, body):
url = "https://api.sendgrid.com/v3/mail/send"
headers = {
"Content-Type": "application/json",
"Authorization": "Bearer YOUR_API_KEY"
}
data = {
"personalizations": [{"to": [{"email": recipient}]}],
"from": {"email": "sender@example.com"},
"subject": subject,
"content": [{"type": "text/plain", "value": body}]
}
response = requests.post(url, headers=headers, json=data)
return response.json()
if __name__ == "__main__":
recipients = ["recipient1@example.com", "recipient2@example.com", "recipient3@example.com"]
subject = "Test Email via Script"
body = "This email is sent to multiple recipients using a script."
with ThreadPoolExecutor(max_workers=5) as executor:
futures = [executor.submit(send_email, recipient, subject, body) for recipient in recipients]
for future in futures:
print(future.result())
此脚本会并发发送邮件给recipients列表中的所有收件人,提高发送效率。
