########################如果想要在邮件中添加附件，加入以下代码
#MIMEText对象，附加邮件附件文件
attach1=MIMEText(open("files/excel.xlsx","rb").read(),"base64","utf-8")
attach2=MIMEText(open("files/img01.jpg","rb").read(),"base64","utf-8")
attach3=MIMEText(open("files/text.txt","rb").read(),"base64","utf-8")
attach4=MIMEText(open("files/word.docx","rb").read(),"base64","utf-8")
#问题1，上面代码中的后面"base64","utf-8")不知道代表什么意思？
#指定文件格式类型
attach1["Content-Type"]="application/octet-stream"
attach2["Content-Type"]="application/octet-stream"
attach3["Content-Type"]="application/octet-stream"
attach4["Content-Type"]="application/octet-stream"
#指定Content-Disposition值为attachment则出现下载保存对话框，保存的默认文件名使用filename指定
#由于QQ邮箱使用gb18030页面编码，为保证中文文件名不出现乱码，对文件名进行编码转换
attach1["Content-Disposition"] = "attachment;filename=\"新建 Microsoft Excel 工作表.xlsx\"".decode("gbk").encode("gb18030")
attach2["Content-Disposition"] = "attachment;filename=\"新建img01.jpg\"".decode("gbk").encode("gb18030")
attach3["Content-Disposition"] = "attachment;filename=\"新建文本文档.txt\"".decode("gbk").encode("gb18030")
attach4["Content-Disposition"] = "attachment;filename=\"新建 Microsoft Word 文档.docx\"".decode("gbk").encode("gb18030")
#问题2，一开始执行这个py文件的时候老是报编码错误的问题，后来将decode("utf-8")改成了decode("gbk")邮件就能正常发送了并且能正常在浏览器中打开附件内容，我想知道如何才能企确认decode("gbk")是否是正确的，这个decode("gbk")是不是就是系统语言编码？
