########################如果想要在郵件中添加附件，加入以下代碼 #MIMEText對象，附加郵件附件文件 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") #問題1，上面代碼中的后面"base64","utf-8")不知道代表什么意思？ #指定文件格式類型 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值為attachment則出現(xiàn)下載保存對話框，保存的默認文件名使用filename指定 #由于QQ郵箱使用gb18030頁面編碼，為保證中文文件名不出現(xiàn)亂碼，對文件名進行編碼轉(zhuǎn)換 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=\"新建文本文檔.txt\"".decode("gbk").encode("gb18030") attach4["Content-Disposition"]?=?"attachment;filename=\"新建?Microsoft?Word?文檔.docx\"".decode("gbk").encode("gb18030") #問題2，一開始執(zhí)行這個py文件的時候老是報編碼錯誤的問題，后來將decode("utf-8")改成了decode("gbk")郵件就能正常發(fā)送了并且能正常在瀏覽器中打開附件內(nèi)容，我想知道如何才能企確認decode("gbk")是否是正確的，這個decode("gbk")是不是就是系統(tǒng)語言編碼？ #MIMEMultipart對象附加MIMEText附件內(nèi)容 msg.attach(attach1) msg.attach(attach2) msg.attach(attach3) msg.attach(attach4)
