如何使用Python在Gmail中发送邮件？新手项目实现需求

针对你的需求，下面给几种常见的实现方式，都是适合新手上手的：

1. 本地测试模拟版本（无需外部服务） #

适合先跑通流程，验证输入和函数逻辑，不用实际发送消息：

msginput = input("What would you like to send?: ")
recipientinput = input("To whom would you like to send this message?: ")

def sending(msginput, recipientinput):
    # 模拟发送成功的提示
    print(f"已成功向 {recipientinput} 发送消息：{msginput}")

# 调用函数执行发送
sending(msginput, recipientinput)

2. 发送邮件（用Python自带的smtplib） #

可以实现给指定邮箱发送消息，需要先开启邮箱的SMTP服务（比如QQ邮箱要在设置里开启POP3/SMTP，获取授权码）：

import smtplib
from email.mime.text import MIMEText
from email.header import Header

msginput = input("What would you like to send?: ")
recipientinput = input("请输入收件人邮箱：")

def sending(msg_content, recipient_email):
    # 配置你的邮箱信息
    sender_email = "你的邮箱地址@xxx.com"
    sender_auth_code = "你的邮箱SMTP授权码"  # 不是登录密码，是SMTP专用授权码
    smtp_server = "smtp.xxx.com"  # 比如QQ邮箱是smtp.qq.com，Gmail是smtp.gmail.com
    smtp_port = 465  # SSL端口，一般是465

    # 构造邮件内容
    message = MIMEText(msg_content, 'plain', 'utf-8')
    message['From'] = Header("消息发送工具", 'utf-8')
    message['To'] = Header(recipient_email, 'utf-8')
    message['Subject'] = Header("来自消息工具的消息", 'utf-8')

    try:
        # 连接SMTP服务器并发送
        server = smtplib.SMTP_SSL(smtp_server, smtp_port)
        server.login(sender_email, sender_auth_code)
        server.sendmail(sender_email, recipient_email, message.as_string())
        print(f"邮件已成功发送到 {recipient_email}")
        server.quit()
    except Exception as e:
        print(f"发送失败：{str(e)}")

# 调用函数
sending(msginput, recipientinput)

3. 发送短信（用Twilio服务） #

如果要发送短信，需要先安装Twilio的Python库，注册Twilio账号获取SID、AUTH_TOKEN和可用的发送手机号：

# 先安装库：pip install twilio
from twilio.rest import Client

msginput = input("What would you like to send?: ")
recipientinput = input("请输入收件人手机号（格式：+国家代码，比如+8613xxxxxxxxx）：")

def sending(msg_content, recipient_phone):
    # 替换成你的Twilio账号信息
    account_sid = "你的Twilio账号SID"
    auth_token = "你的Twilio授权TOKEN"
    twilio_phone = "你的Twilio发送手机号（格式：+国家代码）"

    client = Client(account_sid, auth_token)
    try:
        message = client.messages.create(
            body=msg_content,
            from_=twilio_phone,
            to=recipient_phone
        )
        print(f"短信已发送，消息ID：{message.sid}")
    except Exception as e:
        print(f"发送失败：{str(e)}")

# 调用函数
sending(msginput, recipientinput)
