使用Python的httpx库通过邮件枪API发送带有附件的邮件

pip install httpx

import httpx
import json
import base64

def build_email_request():
    request_data = {
        "from": "sender@example.com",
        "to": "recipient@example.com",
        "subject": "邮件主题",
        "text": "邮件正文内容"
    }

    with open("attachment.pdf", "rb") as file:
        attachment_data = base64.b64encode(file.read()).decode("utf-8")
        request_data["attachment"] = {
            "name": "attachment.pdf",
            "data": attachment_data
        }

    return request_data

def send_email():
    api_url = "https://api.mailgun.net/v3/your-domain.com/messages"
    api_key = "your-api-key"

    request_data = build_email_request()

    headers = {
        "Authorization": f"Basic {base64.b64encode(f'api:{api_key}'.encode('utf-8')).decode('utf-8')}"
    }

    response = httpx.post(api_url, headers=headers, data=request_data)

    if response.status_code == 200:
        print("邮件发送成功")
    else:
        print("邮件发送失败")

send_email()
