python哄骗imap实现伪“无痕”取信
添加时间:2013-8-8 点击量:
所谓无痕取信,今朝主如果指从邮箱中把信件收取后,邮箱内状况不产生任何改变。这里的状况主如果指两项目组,一项目组是邮件状况不变,即已读与未读状况不变,另一项目组是指邮箱记录的登岸IP不产生改变。本文中所说的伪“无痕”取信主如果指实现第一项目组。

FETCH <mail id><datanames>:FETCH 号令用于读取邮件的文本信息,且仅用于显示的目标。包含两个参数,messageset:默示读取的邮件号列表,IAMP办事器邮箱中的每个邮件都有 一个独一的ID标识,(邮件号列表参数可所以一个邮件号,也可所以由逗号分隔的多个邮件号,或者由冒号间隔的一个局限),IMAP办事器返回邮件号列表中 全部邮件的指定命据项内容。
数据名参数断定可以或许被自力返回的邮件的一项目组,下面我们看看各参数返回的邮件信息:
ALL:只返回遵守必然格局的邮件择要,包含邮件标记、RFC822.SIZE、自身的时候和信封信息。IMAP客户性可以或许将标准邮件解析成这些信息并显示出来。
BODY:只返回邮件体文本格局和大小的择要信息。IMAP客户机可以辨认这些细腻,并向用户显示具体的关于邮件的信息。其实是一些非扩大的BODYSTRUCTURE的信息。
FAST:只返回邮件的一些择要,包含邮件标记、RFC822.SIZE、和自身的时候。
FULL:同样的还是一些择要信息,包含邮件标记、RFC822.SIZE、自身的时候和BODYSTRUCTURE的信息。
BODYSTRUCTUR: 是邮件的[MIME-IMB]的体布局。这是办事器经由过程解析[RFC-2822]头中的[MIME-IMB]各字段和[MIME-IMB]头信息得出来 的。包含的内容有:邮件正文的类型、字符集、编码体式格式等和各附件的类型、字符集、编码体式格式、文件名称等等。

BODY[section] <<partial>>:返回邮件的中的某一指定项目组,返回的项目组用section来默示,section项目组包含的信息凡是是 代表某一项目组的一个数字或者是下面的某一个项目组:HEADER, HEADER.FIELDS, HEADER.FIELDS.NOT, MIME, and TEXT。若是section项目组是空的话,那就代表返回全部的信息,包含头信息。
BODY[HEADER]返回完全的文件头信息。
BODY[HEADER.FIELDS ()]:在小括号里面可以指定返回的特定字段。
BODY[HEADER.FIELDS.NOT ()]:在小括号里面可以指定不须要返回的特定字段。
BODY[MIME]:返回邮件的[MIME-IMB]的头信息,在正常景象下跟BODY[HEADER]没有差别。
BODY[TEXT]:返回全部邮件体,这里的邮件体并不包含邮件头。
STORE <mail id><new attributes>:STORE 号令用于批改指定邮件的属性,包含给邮件打上已读标识表记标帜、删除标识表记标帜,等等。STORE号令当前只有两个数据项类型可用,FLAGS:默示邮件的一组标记; FLAGS.SLIENT,默示一组邮件的标记,经由过程在两种数据项前加上加号或者减号可以进一步改变它们的履行景象,加号默示数据项的值添加到邮件中,减 号默示将数据项的值从邮件中删除。
C: A003 STORE 2:4 +FLAGS (\Deleted) /冒号默示间隔的一个局限:给从2到4的邮件设置Deleted属性/
S: 2 FETCH FLAGS (\Deleted \Seen)
S: 3 FETCH FLAGS (\Deleted)
S: 4 FETCH FLAGS (\Deleted \Flagged \Seen)
S: A003 OK STORE completed
同时改号令还可以用于把邮件标识表记标帜为未读等等。在web上可以对邮件进行的操纵在imap中都可以实现。
CLOSE:CLOSE号令默示Client停止对当前Folder(文件夹/邮箱)的接见,封闭邮箱该邮箱中所有标记为、DELETED的邮件就被从物理上删除。CLOSE没有号令参数。随后可以SELECT另一Folder。
C: A341 CLOSE
S: A341 OK CLOSE completed
EXPUNGE:EXPUNGE号令在不封闭邮箱的景象下删除所有的标记为、DELETED的邮件。EXPUNGE删除的邮件将不成以恢复。
C: A202 EXPUNGE
S: 3 EXPUNGE
S: 3 EXPUNGE
S: 5 EXPUNGE

S: A202 OK EXPUNGE completed
LOGOUT:LOGOUT号令停止本次IMAP会话。
C: A023 LOGOUT
S: BYE IMAP4rev1 Server logging out
S: A023 OK LOGOUT completed
(Server and client then close the connection)
EXAMINE <mailbox>:
EXAMINE号令以只读体式格式打开邮箱,参数是须要打开的邮箱的名字,应用EXAMINE号令打开的邮箱不容许对邮件进行批改,是以不克不及增长或删除邮件的标记。
SUBSCRIBE <mailbox>:SUBSCRIBE号令用来在客户机的活动邮箱列表中增长一个邮箱,该号令只有一个参数,添加的邮箱名。
C: A114 SUBSCRIBE new/anotherbox
S: A114 OK SUBSCRIBE completed
UNSUBSCRIBE <mailbox>:UNSUBSCRIBE号令用来从活动列表中去掉一个邮箱,一个参数:去掉的邮箱名。
C: A115 UNSUBSCRIBE new/anotherbox
S: A115 OK SUBSCRIBE completed
LSUB <folder><mailbox>:LSUB号令批改了LIST号令,LIST返回用户¥HOME目次下所有的文件,但LSUB号令只显示那些应用SUBSCRIBE号令设置为活动邮箱的文件。两个参数:邮箱路径和邮箱名。
C: A116 LSUB “”
S: LSUB () “/” stuff/junk
S: LSUB () “/” neebox
S: LSUB () “/” new/anotherbox
S: A116 OK LSUB completed
STATUS <mailbox>(<parameter1> < parameter2> ……<parameter5>):STATUS号令查询邮箱的当前状况。第一个参数是须要查询的邮箱名,第二个参数是客户机须要查询的项目列表(要查询显示的信息),当在圆括号中。STATUS可以在不应用SELECT号令(打开邮箱)或者EXAMINE(以只读体式格式打开邮箱)前提下获取邮箱的信息。
STATUS号令可以获得的数据项
项 目 说 明
MESSAGE 邮箱中的邮件总数
RECENT 邮箱中标记为\RECENT的邮件数
UIDNEXT 可以分派给新邮件的下一个UID
UIDVALIDITY 邮箱的UID有效性标记
UNSEEN 邮箱中没有被标记为\UNSEEN的邮件数
C: A117 STATUS inbox (message recent unseen)
S: STATUS inbox (MESSAGE 1 RECENT 0 UNSENN 0)
S: A117 OK STATUS completed
C: A118 STATUS newbox (message recent unseen)
S: STATUS inbox (MESSAGE 1 RECENT 0 UNSENN 2)
S: A118 OK STATUS completed
CHECK :CHECK号令用来在邮箱设置一个搜检核。没有参数。就是IMAP中的sync号令。任何未完成的操纵,例如从办事器内存向硬盘写数据,都将会被做完以对峙邮箱的一致性状况。该号令确保乃村中的磁盘缓冲数据都被写到了磁盘上。
SEARCH [CHARSET specification] (search criteria):命 令可以按照搜刮前提在处于活动状况的邮箱中搜刮邮件,然后显示匹配的邮件编号。字符集标记参数[CHARSET specification]由CHARSET和注册的字符集标记符构成,缺省的标记符是US-ASCⅡ,所以该参数长省略。search criteria:查询前提参数,明白查询的关键字和值。查询关键字有几十种。
C: A119 SEARCH header subject another
S: SEARCH 1 2
S: A119 OK SEARCH completed
C: A120 SEARCH header subject another
S: SEARCH 2
S: A120 OK SEARCH completed
C: A121 SEARCH UNSEEN
S: SEARCH 1 2
S: A120 OK SEARCH completed
以上每个例子都在邮件头的Subject:字段中查询一个不合的单词。办事器返回前提的邮件号列表,若是没有匹配邮件则返回不带UID的SEARCH单词。
COPY <mail id><mailboxname>:COPY号令可以把邮件从一个邮箱复制到另一个邮箱,两个参数:mail id是从活动邮箱中复制的邮件的标号,mailboxname是邮件被复制到的邮箱。
IAMP没有定义移动邮件的号令,移动操纵相当于先把邮件复制到新邮箱中,然后对源邮箱中的邮件设置\DELETED标记。下一次履行搜检核过后,新邮箱中的邮件被删除,新邮件就被显示出来。
UID:UID 号令和FETCH、COPY、STORE号令或者SEARCH号令一路应用,它容许这些号令应用邮件的UID号而不是在邮箱中的次序号。UID号是独一标 识邮件体系中邮件的32位。凡是这些号令都应用次序号来标识邮箱中的邮件,应用UID可以使IMAP客户机记住不合IMAP会话中的邮件。
CAPABILITY:CAPABILITY号令恳求返回IMAP办事器支撑的功能列表,办事器收到客户机发送的CAPABILITY号令后将返回该办事器所支撑的功能。无参数。
C: A122 CAPABILITY
S:A122 CAPABILITY IMAP4 IMAP4REVl NAMESPACE IDLE SCAN SORT MAILBOX
--REFERRALS [ic:ccc] LOGIN-REFERRALS AUTH=LOGIN THREAD=
ORDERDSUBJECT
S: A122 OK CAPABILITY completed
NOOP:NOOP号令什么也不做,用来向办事器发送主动号令,防止因长时候处于不活动状况而导致连接中断,办事器对该号令的响应始终为必然。无参数。
LOGOUT:LOGOUT号令使当前登岸用户退出登岸并封闭所有打开的邮箱,任何做了\DELETED标记的邮件都将在这个时辰被删除。
二、以yahoo邮箱为例进行伪无痕收信
要做到邮件状况不产生变更,实现上关键在fetch的参数上。若是我们仅是读取邮件头BODY.PEEK[HEADER],那么邮件的状况是不产生变更的。若是我们要读取全部邮件内容,那么必须应用BODY.PEEK[],如许才干包管不产生变更。如下面的例子:
#-- coding:UTF-8 --
#@小五义 http://www.cnblogs.com/xiaowuyi
import imaplib, string, email
import os
M = imaplib.IMAP4_SSL(imap.mail.yahoo.com,993)
t=0
try:
try:
M.login(XXXX@yahoo.com,YYYY)####YYYY为暗码
except Exception,e:
#print wrong!
print login error: %s % e
M.close()
M.(INBOX,False)
result, message = M.()
typ, data = M.search(None, ALL)
for num in string.split(data[0]):
try:
typ, data = M.fetch(num, (UID BODY.PEEK[]))
msg = email.message__string(data[0][1])
t=t+1
filename=str(t)+.eml
f=open(filename,wb)
f.write(str(msg))
f.close
except Exception,e:
print got msg error: %s % e
print OK!
M.logout()
except Exception, e:
print imap error: %s % e
M.close()
前面说的有些抽象,typ, data = M.fetch(num, (UID BODY.PEEK[]))在这一句中,可以偿试着将UID BODY.PEEK[HEADER]、UID BODY[]、RFC822、RFC822.HEADER等进行收信斗劲,将会加倍直观。这里就不再一一申明。
无论对感情还是对生活,“只要甜不要苦”都是任性而孩子气的,因为我们也不完美,我们也会伤害人。正因为我们都不完美,也因为生活从不是事事如意,所以对这些“瑕疵”的收纳才让我们对生活、对他人的爱变得日益真实而具体。—— 汪冰《世界再亏欠你,也要敢于拥抱幸福》
所谓无痕取信,今朝主如果指从邮箱中把信件收取后,邮箱内状况不产生任何改变。这里的状况主如果指两项目组,一项目组是邮件状况不变,即已读与未读状况不变,另一项目组是指邮箱记录的登岸IP不产生改变。本文中所说的伪“无痕”取信主如果指实现第一项目组。

FETCH <mail id><datanames>:FETCH 号令用于读取邮件的文本信息,且仅用于显示的目标。包含两个参数,messageset:默示读取的邮件号列表,IAMP办事器邮箱中的每个邮件都有 一个独一的ID标识,(邮件号列表参数可所以一个邮件号,也可所以由逗号分隔的多个邮件号,或者由冒号间隔的一个局限),IMAP办事器返回邮件号列表中 全部邮件的指定命据项内容。
数据名参数断定可以或许被自力返回的邮件的一项目组,下面我们看看各参数返回的邮件信息:
ALL:只返回遵守必然格局的邮件择要,包含邮件标记、RFC822.SIZE、自身的时候和信封信息。IMAP客户性可以或许将标准邮件解析成这些信息并显示出来。
BODY:只返回邮件体文本格局和大小的择要信息。IMAP客户机可以辨认这些细腻,并向用户显示具体的关于邮件的信息。其实是一些非扩大的BODYSTRUCTURE的信息。
FAST:只返回邮件的一些择要,包含邮件标记、RFC822.SIZE、和自身的时候。
FULL:同样的还是一些择要信息,包含邮件标记、RFC822.SIZE、自身的时候和BODYSTRUCTURE的信息。
BODYSTRUCTUR: 是邮件的[MIME-IMB]的体布局。这是办事器经由过程解析[RFC-2822]头中的[MIME-IMB]各字段和[MIME-IMB]头信息得出来 的。包含的内容有:邮件正文的类型、字符集、编码体式格式等和各附件的类型、字符集、编码体式格式、文件名称等等。
ENVELOPE:信息的信封布局。是办事器经由过程解析[RFC-2822]头中的[MIME-IMB]各字段得出来的,默认各字段都是须要的。首要包含:自身的时候、附件数、收件人、发件人等。
FLAGS:此邮件的标记。
INTERNALDATE:自身的时候。
RFC822.SIZE:邮件的[RFC-2822]大小
RFC822.HEADER:在功能上等同于BODY.PEEK[HEADER],
RFC822:功能上等同于BODY[]。
RFC822.TEXT:功能上等同于BODY[TEXT]
UID:返回邮件的UID号,UID号是独一标识邮件的一个号码。
BODY[section] <<partial>>:返回邮件的中的某一指定项目组,返回的项目组用section来默示,section项目组包含的信息凡是是 代表某一项目组的一个数字或者是下面的某一个项目组:HEADER, HEADER.FIELDS, HEADER.FIELDS.NOT, MIME, and TEXT。若是section项目组是空的话,那就代表返回全部的信息,包含头信息。
BODY[HEADER]返回完全的文件头信息。
BODY[HEADER.FIELDS ()]:在小括号里面可以指定返回的特定字段。
BODY[HEADER.FIELDS.NOT ()]:在小括号里面可以指定不须要返回的特定字段。
BODY[MIME]:返回邮件的[MIME-IMB]的头信息,在正常景象下跟BODY[HEADER]没有差别。
BODY[TEXT]:返回全部邮件体,这里的邮件体并不包含邮件头。
STORE <mail id><new attributes>:STORE 号令用于批改指定邮件的属性,包含给邮件打上已读标识表记标帜、删除标识表记标帜,等等。STORE号令当前只有两个数据项类型可用,FLAGS:默示邮件的一组标记; FLAGS.SLIENT,默示一组邮件的标记,经由过程在两种数据项前加上加号或者减号可以进一步改变它们的履行景象,加号默示数据项的值添加到邮件中,减 号默示将数据项的值从邮件中删除。
C: A003 STORE 2:4 +FLAGS (\Deleted) /冒号默示间隔的一个局限:给从2到4的邮件设置Deleted属性/
S: 2 FETCH FLAGS (\Deleted \Seen)
S: 3 FETCH FLAGS (\Deleted)
S: 4 FETCH FLAGS (\Deleted \Flagged \Seen)
S: A003 OK STORE completed
同时改号令还可以用于把邮件标识表记标帜为未读等等。在web上可以对邮件进行的操纵在imap中都可以实现。
CLOSE:CLOSE号令默示Client停止对当前Folder(文件夹/邮箱)的接见,封闭邮箱该邮箱中所有标记为、DELETED的邮件就被从物理上删除。CLOSE没有号令参数。随后可以SELECT另一Folder。
C: A341 CLOSE
S: A341 OK CLOSE completed
EXPUNGE:EXPUNGE号令在不封闭邮箱的景象下删除所有的标记为、DELETED的邮件。EXPUNGE删除的邮件将不成以恢复。
C: A202 EXPUNGE
S: 3 EXPUNGE
S: 3 EXPUNGE
S: 5 EXPUNGE
S: 8 EXPUNGE
S: A202 OK EXPUNGE completed
LOGOUT:LOGOUT号令停止本次IMAP会话。
C: A023 LOGOUT
S: BYE IMAP4rev1 Server logging out
S: A023 OK LOGOUT completed
(Server and client then close the connection)
EXAMINE <mailbox>:
EXAMINE号令以只读体式格式打开邮箱,参数是须要打开的邮箱的名字,应用EXAMINE号令打开的邮箱不容许对邮件进行批改,是以不克不及增长或删除邮件的标记。
SUBSCRIBE <mailbox>:SUBSCRIBE号令用来在客户机的活动邮箱列表中增长一个邮箱,该号令只有一个参数,添加的邮箱名。
C: A114 SUBSCRIBE new/anotherbox
S: A114 OK SUBSCRIBE completed
UNSUBSCRIBE <mailbox>:UNSUBSCRIBE号令用来从活动列表中去掉一个邮箱,一个参数:去掉的邮箱名。
C: A115 UNSUBSCRIBE new/anotherbox
S: A115 OK SUBSCRIBE completed
LSUB <folder><mailbox>:LSUB号令批改了LIST号令,LIST返回用户¥HOME目次下所有的文件,但LSUB号令只显示那些应用SUBSCRIBE号令设置为活动邮箱的文件。两个参数:邮箱路径和邮箱名。
C: A116 LSUB “”
S: LSUB () “/” stuff/junk
S: LSUB () “/” neebox
S: LSUB () “/” new/anotherbox
S: A116 OK LSUB completed
STATUS <mailbox>(<parameter1> < parameter2> ……<parameter5>):STATUS号令查询邮箱的当前状况。第一个参数是须要查询的邮箱名,第二个参数是客户机须要查询的项目列表(要查询显示的信息),当在圆括号中。STATUS可以在不应用SELECT号令(打开邮箱)或者EXAMINE(以只读体式格式打开邮箱)前提下获取邮箱的信息。
STATUS号令可以获得的数据项
项 目 说 明
MESSAGE 邮箱中的邮件总数
RECENT 邮箱中标记为\RECENT的邮件数
UIDNEXT 可以分派给新邮件的下一个UID
UIDVALIDITY 邮箱的UID有效性标记
UNSEEN 邮箱中没有被标记为\UNSEEN的邮件数
C: A117 STATUS inbox (message recent unseen)
S: STATUS inbox (MESSAGE 1 RECENT 0 UNSENN 0)
S: A117 OK STATUS completed
C: A118 STATUS newbox (message recent unseen)
S: STATUS inbox (MESSAGE 1 RECENT 0 UNSENN 2)
S: A118 OK STATUS completed
CHECK :CHECK号令用来在邮箱设置一个搜检核。没有参数。就是IMAP中的sync号令。任何未完成的操纵,例如从办事器内存向硬盘写数据,都将会被做完以对峙邮箱的一致性状况。该号令确保乃村中的磁盘缓冲数据都被写到了磁盘上。
SEARCH [CHARSET specification] (search criteria):命 令可以按照搜刮前提在处于活动状况的邮箱中搜刮邮件,然后显示匹配的邮件编号。字符集标记参数[CHARSET specification]由CHARSET和注册的字符集标记符构成,缺省的标记符是US-ASCⅡ,所以该参数长省略。search criteria:查询前提参数,明白查询的关键字和值。查询关键字有几十种。
C: A119 SEARCH header subject another
S: SEARCH 1 2
S: A119 OK SEARCH completed
C: A120 SEARCH header subject another
S: SEARCH 2
S: A120 OK SEARCH completed
C: A121 SEARCH UNSEEN
S: SEARCH 1 2
S: A120 OK SEARCH completed
以上每个例子都在邮件头的Subject:字段中查询一个不合的单词。办事器返回前提的邮件号列表,若是没有匹配邮件则返回不带UID的SEARCH单词。
COPY <mail id><mailboxname>:COPY号令可以把邮件从一个邮箱复制到另一个邮箱,两个参数:mail id是从活动邮箱中复制的邮件的标号,mailboxname是邮件被复制到的邮箱。
IAMP没有定义移动邮件的号令,移动操纵相当于先把邮件复制到新邮箱中,然后对源邮箱中的邮件设置\DELETED标记。下一次履行搜检核过后,新邮箱中的邮件被删除,新邮件就被显示出来。
UID:UID 号令和FETCH、COPY、STORE号令或者SEARCH号令一路应用,它容许这些号令应用邮件的UID号而不是在邮箱中的次序号。UID号是独一标 识邮件体系中邮件的32位。凡是这些号令都应用次序号来标识邮箱中的邮件,应用UID可以使IMAP客户机记住不合IMAP会话中的邮件。
CAPABILITY:CAPABILITY号令恳求返回IMAP办事器支撑的功能列表,办事器收到客户机发送的CAPABILITY号令后将返回该办事器所支撑的功能。无参数。
C: A122 CAPABILITY
S:A122 CAPABILITY IMAP4 IMAP4REVl NAMESPACE IDLE SCAN SORT MAILBOX
--REFERRALS [ic:ccc] LOGIN-REFERRALS AUTH=LOGIN THREAD=
ORDERDSUBJECT
S: A122 OK CAPABILITY completed
NOOP:NOOP号令什么也不做,用来向办事器发送主动号令,防止因长时候处于不活动状况而导致连接中断,办事器对该号令的响应始终为必然。无参数。
LOGOUT:LOGOUT号令使当前登岸用户退出登岸并封闭所有打开的邮箱,任何做了\DELETED标记的邮件都将在这个时辰被删除。
二、以yahoo邮箱为例进行伪无痕收信
要做到邮件状况不产生变更,实现上关键在fetch的参数上。若是我们仅是读取邮件头BODY.PEEK[HEADER],那么邮件的状况是不产生变更的。若是我们要读取全部邮件内容,那么必须应用BODY.PEEK[],如许才干包管不产生变更。如下面的例子:
#-- coding:UTF-8 --
#@小五义 http://www.cnblogs.com/xiaowuyi
import imaplib, string, email
import os
M = imaplib.IMAP4_SSL(imap.mail.yahoo.com,993)
t=0
try:
try:
M.login(XXXX@yahoo.com,YYYY)####YYYY为暗码
except Exception,e:
#print wrong!
print login error: %s % e
M.close()
M.(INBOX,False)
result, message = M.()
typ, data = M.search(None, ALL)
for num in string.split(data[0]):
try:
typ, data = M.fetch(num, (UID BODY.PEEK[]))
msg = email.message__string(data[0][1])
t=t+1
filename=str(t)+.eml
f=open(filename,wb)
f.write(str(msg))
f.close
except Exception,e:
print got msg error: %s % e
print OK!
M.logout()
except Exception, e:
print imap error: %s % e
M.close()
前面说的有些抽象,typ, data = M.fetch(num, (UID BODY.PEEK[]))在这一句中,可以偿试着将UID BODY.PEEK[HEADER]、UID BODY[]、RFC822、RFC822.HEADER等进行收信斗劲,将会加倍直观。这里就不再一一申明。
无论对感情还是对生活,“只要甜不要苦”都是任性而孩子气的,因为我们也不完美,我们也会伤害人。正因为我们都不完美,也因为生活从不是事事如意,所以对这些“瑕疵”的收纳才让我们对生活、对他人的爱变得日益真实而具体。—— 汪冰《世界再亏欠你,也要敢于拥抱幸福》
