 Python提供了非常简单的第三方库支持普通邮件的发送，同时也支持带附件 ``` import smtplib from email import encoders from email.header import Header from email.mime.text import MIMEText from email.mime.multipart import MIMEMultipart , MIMEBase ##需要传入发送人的地址，登录密码，收件人的地址，邮件正文，邮件主题，附件的存放路径 def send_mail(self,From,password,To,text,subject,filepath): #构造一个邮件对象 message = MIMEMultipart() message["From"] = From message["To"] = To message["Subject"] = Header(str(subject),"utf-8").encode() #添加邮件正文 message.attach(MIMEText(str(text),"plain","utf-8")) try: #从本地读取附件文件 with open(filepath,"rb") as f : #创建一个附件对象，并描述其文件类型和文件名 mime = MIMEBase("text","plain",filename =("gbk","",filepath.split("/")[-1])) mime.add_header("Content-Disposition", "attachment", filename=("gbk","",filepath.split("/")[-1])) mime.add_header("Content-ID", "<0>") mime.add_header("X-Attachment-Id", "0") #把附件读取进已经描述好的附件对象里 mime.set_payload(f.read()) #用Base64编码附件对象 encoders.encode_base64(mime) #把附件添加到邮件对象 message.attach(mime) except Exception as e : print("附件添加失败--->",str(e)) #连接邮箱服务器 server = smtplib.SMTP("smtp.exmail.qq.com",25) try: #设置输出日志到控制台 #server.set_debuglevel(1) #登录邮箱 server.login(From,password) print("登录成功") #发送邮件 server.sendmail(From,To.split(","),message.as_string()) print("发送成功！") except Exception as e : print("发送失败--->",str(e)) finally: server.quit() ```
