用Python接收邮件和附件

用Python接收邮件和附件

接收邮件的服务又好几种， 这里主要用到pop3 协议， 关于开通和，请看百度经验，获取授权码，点击这里

加入删除和查看上一封功能：

添加了一些小functions

## 从List中寻找匹配
def grep(Str,List):
    for i in List:
        if Str in str(i):
            break
    return i

## 汉字解码
def Decode(STR):
    head = "=?gb2312?b?"
    tail = "?="
    if head in STR:
        H = STR.find(head) + len(head)
        T = STR.find(tail)
        Result = base64.b64decode(STR[H:T]).decode("GBK")
        STR = STR[:H- len(head)] + Result + STR[T+ len(tail):]
    return STR

## 读取邮件
def M_read(index):
    resp, lines, octets = server.retr(index)
    try:
        Date= str(grep("b'Date:",lines)).replace("b'",'')
        msg_content = b'\r\n'.join(lines).decode('utf-8')
        msg = Parser().parsestr(msg_content)
        print_info(msg)
        print('\n\n'+Date)
    except:
        Date= str(grep("b'Date:",lines)).replace("b'",'')
        From= Decode(str(grep("b'From:",lines)).replace("b'",''))
        To= Decode(str(grep("b'To:",lines)).replace("b'",''))
        Subject= Decode(str(grep("b'Subject:",lines)).replace("b'",''))
        print("",From,To,"\n",Subject,'\n\n',"this mail are purely composed by img or html",sep='\n')
        print('\n\n'+Date)


## 按键对应事件
def Action(Press):
    global index
    global Num_mail
    if Press == "q":
        server.quit()
    if Press == "7":
        server.dele(index)
        index -=1
        Num_mail -=1
    elif Press == "8":
        index -=1
    elif Press == "5":
        index +=1
    if index < 0:
        index =0
    elif index > Num_mail:
        index -= 1
    if index == 0:
        print("No more new e-mails")
    else:
        M_read(index)

主逻辑

def M_read(index):
   resp, lines, octets = server.retr(index)
   try:
       Date= str(grep(“b’Date:”,lines)).replace(“b’”,‘’)
       msg_content = b’\r\n’.join(lines).decode(‘utf-8’)
       msg = Parser().parsestr(msg_content)
       print_info(msg)
       print(‘\n\n’+Date)
   except:
       Date= str(grep(“b’Date:”,lines)).replace(“b’”,‘’)
       From= Decode(str(grep(“b’From:”,lines)).replace(“b’”,‘’))
       To= Decode(str(grep(“b’To:”,lines)).replace(“b’”,‘’))
       Subject= Decode(str(grep(“b’Subject:”,lines)).replace(“b’”,‘’))
       print(“”,From,To,“\n”,Subject,‘\n\n’,“this mail are purely composed by img or html”,sep=‘\n’)
       print(‘\n\n’+Date)

while True:
    Press = input()
    os.system('clear')
    if Press == "q":
        break
    if Num_mail == 0:
        print("No New E-mails")
    else:
        Action(Press)
        print("index=",index,"; all=",Num_mail)

案件说明：
8：上一封
5：下一封
7：删除此封
q：退出
注： 只有正常退出，才能够同时删除邮箱中的邮件。删除后在垃圾箱中，不会永久删除。

下载附件

function： Source

def get_email_content(byte_lines, savepath):
    str_lines = []
    for x in byte_lines:
        str_lines.append(x.decode())
    # 拼接邮件内容
    msg_content = '\n'.join(str_lines)
    # 把邮件内容解析为Message对象
    message = Parser().parsestr(msg_content)
    attachments = []
    for part in message.walk():
        filename = part.get_filename()
        #附件名字
        if filename:
            print(filename)
            filename = decode_str(filename)
            data = part.get_payload(decode=True)
            abs_filename = os.path.join(savepath, filename)
            attach = open(abs_filename, 'wb')
            attachments.append(filename)
            attach.write(data)
            attach.close()
    return attachments

添加入action，按9下载：

elif Press == "9":        
    attach = get_email_content(M_read(index), '.')

加个获取附件名称， 发现中文乱码问题， 加个decode

def get_attach_name(byte_lines):
    str_lines = []
    for x in byte_lines:
        str_lines.append(x.decode())
    # 拼接邮件内容
    msg_content = '\n'.join(str_lines)
    # 把邮件内容解析为Message对象
    message = Parser().parsestr(msg_content)
    attachments = []
    for part in message.walk():
        filename = part.get_filename()
        #附件名字
        if filename:
            if "=?UTF-8?" in filename:
                filename = base64.b64decode(filename[9:-2]).decode("utf8")
            attachments.append(filename)
    return attachments


def M_read(index):
    resp, lines, octets = server.retr(index)
    try:
        Attachment = get_attach_name(lines)
        Date= str(grep("b'Date:",lines)).replace("b'",'')
        msg_content = b'\r\n'.join(lines).decode('utf-8')
        msg = Parser().parsestr(msg_content)
        print_info(msg)
        print('\n\n'+Date)
        print("Attachment:",Attachment)
##    try:
    except:
        Date= str(grep("b'Date:",lines)).replace("b'",'')
        From= Decode(str(grep("b'From:",lines)).replace("b'",''))
        To= Decode(str(grep("b'To:",lines)).replace("b'",''))

## 输入邮件地址, 口令和POP3服务器地址:
email = '591465908@qq.com'
password = ''
pop3_server = 'pop.qq.com'
port = 995


## 连接到POP3服务器:
server = poplib.POP3_SSL(pop3_server, port)
server.user(email)
server.pass_(password)

## stat()返回邮件数量和占用空间:
print('Messages: %s. Size: %s' % server.stat())
## list()返回所有邮件的编号:
resp, mails, octets = server.list()
## 可以查看返回的列表类似[b'1 82923', b'2 2184', ...]
Num_mail = len(mails)

## 获取最新一封邮件, 注意索引号从1开始:
index = len(mails)

##M_read(index)

while True:
    Press = input()
    os.system('clear')
    if Press == "q":
        break
    if Num_mail == 0:
        print("No New E-mails")
    else:
        Action(Press)
        print("index=",index,"; all=",Num_mail)

## lines存储了邮件的原始文本的每一行,

## 可以根据邮件索引号直接从服务器删除邮件:
## server.dele(index)
## 关闭连接:
server.quit()

效果：

删除邮件后保存并刷新

经过几次测试，我发现， 被删除的index并不会重拍，而是就空载那里了， 再次返回查看邮件的时候， 就会出现错误。 因此，最保险的方法，自然是保存和刷新了。同理，如果不保存，只刷新，那么就可以“撤销” 以删除的邮件。

开始想Action那里加上一个，退出，再重连就好～ 
但是server套在函数里面刷新的时候会报错， = =这样就麻烦了， 所以直接都在mainloop了- -反正 - -以后应该不会debug什么的了。

if Press == "s":
    print("ReFreshing...")
    server.quit()
    server, resp, mails, octets, Num_mail = Refresh()

删除以后保存

## list()返回所有邮件的编号:
resp, mails, octets = server.list()
## 可以查看返回的列表类似[b'1 82923', b'2 2184', ...]
Num_mail = len(mails)

## 获取最新一封邮件, 注意索引号从1开始:
index = len(mails)

##M_read(index)

while True:
    Press = INPUT_delay()
    if Press == "q":
        break
    if Press == "Fresh" or Press == "f":
        print("ReFreshing...")
        server, resp, mails, octets, Num_mail = Refresh()
    if Press == "s":
        print("Save & ReFreshing...")
        server.quit()
        server, resp, mails, octets, Num_mail = Refresh()
    if Num_mail == 0:
        os.system('clear')
        print("No New E-mails")
    else:
        os.system('clear')
        Action(Press,server)
        print("index=",index,"; all=",Num_mail)

## lines存储了邮件的原始文本的每一行,

## 可以根据邮件索引号直接从服务器删除邮件:
## server.dele(index)
## 关闭连接:
server.quit()
