您好我在这里经历了各种各样的帖子,但没有人回答我的问题,我有两个问题, 1。 我写了一个脚本来使用poplib获取电子邮件,everythig工作正常,直到我试图解析电子邮件的正文,它摆脱了标签加上里面的数据,我现在放弃了,我在这里寻求帮助希望你那些人会引导我走向正确的方向,因为我在做错了,或者我应该做些什么来使它发挥作用。
这是解析器脚本的来源
import sys
import socket
import poplib
import email
import csv
import re
try:
host = "mail.someserver.com"
mail = poplib.POP3(host)
print mail.getwelcome()
print mail.user("username@someserver.com")
print mail.pass_("qaiaJWkvZT")
print mail.stat()
print mail.list()
print ""
emailWriter = csv.writer(open('emailMessages.csv', 'wb'), delimiter=',', quotechar='\'', quoting=csv.QUOTE_MINIMAL)
emailWriter.writerow(['Messages'])
if mail.stat()[1] > 0:
print "You have new mail."
else:
print "No new mail."
print ""
numMessages = len(mail.list()[1])
for i in range(numMessages):
for j in mail.retr(i+1)[1]:
#print j
msg = email.message_from_string(j) # new statement
print msg.get_payload(decode=True)
#emailWriter.writerow([msg.get_payload(decode=True)]) # new statement
mail.quit()
input("Press any key to continue.")
except socket.error as e:
print "Something went wrong! :(\nREASON:\n{0}:{1}".format(e.errno, e.strerror)
raise
except:
print "Something went wrong!", sys.exc_info()[0]
raise
以下是上述脚本生成的输出

但是,如果我将脚本更改为直接在循环内打印j变量,它会给我这个

如果我需要处理原始消息,我怎样才能有效地获取消息的正文部分,删除不必要的html标记而不丢失任何数据?或者,如果可以通过使用get_payload()方法,我该怎么做才能使它工作。
请帮忙!
2。 还有一种方法可以使用正则表达式获取表中包含的所有SKU信息吗?如果你能提供给我那将是一个加号。万分感谢
答案 0 :(得分:1)
好的,我自己找到了答案,文档说明全部,Python: How to get HTML body of an email message using poplib?的帖子帮助我朝着正确的方向前进。我知道我正在处理的消息不是多部分类型,而是应用了get_payload()丢失了html数据,这就是为什么我必须实现一些正则表达式例程来从原始消息中去除html标签,因为我在原始消息上下载并使用了Aaron Swartz的html2text库,然后执行了msg.get_payload() ..这就是我所做的
import html2text # added to my source
numMessages = len(mail.list()[1])
for i in range(numMessages):
for j in mail.retr(i+1)[1]:
msg = email.message_from_string(html2text.html2text(j))
print msg.get_payload(decode=False)
反过来给了我

现在我只需要用正则表达式来清理它,以获得不必要的换行/空格和css标记的reif。
希望它对其他人也有帮助:)干杯!
