使用python解析操作服务器的电子邮件

Question

我在论坛上找到了这个python代码，以回答与我的问题相关的问题。我不太懂python，所以有人能告诉我为什么这个不能用吗？

(一些背景信息:我有一个网页表单，它会自动通过电子邮件发送到openERP，然后它会自动创建一个引线。然而，当创建一个引线时，像电话和名称这样的信息不会从电子邮件中读取，并以铅的形式排序到相应的字段中。)

# You can use the following variables:
#  - self: ORM model of the record on which the action is triggered
#  - object: browse_record of the record on which the action is triggered if there is one, otherwise None
#  - pool: ORM model pool (i.e. self.pool)
#  - time: Python time module
#  - cr: database cursor
#  - uid: current user id
#  - context: current context
# If you plan to return an action, assign: action = {...}

def parse_description(description):

   there is parse function
   It is example for parsing messages like this:

   Name: John
   Phone: +100500
  '''
  fields=['Name','Phone']
  _dict={}
  description=description.lower()
  for line in description.split('\n'):
    for field in fields:
        if field in line:
            split_line=line.split(':')
            if len(split_line)>1:
                pre_dict[field]=line.split(':')[1]
  return  dict

lead=self.browse(cr,uid,context['active_id'],context=context)
description=lead['description']
_dict=parse_description(description)
self.write(cr,uid,context['active_id'],{
                        'partner_name':_dict.get('name'),
                        'contact_name':_dict.get('name'),
                        'phone':_dict.get(u'phone'),
                        'mobile':_dict.get(u'phone')})

当我取邮件时，我得到了这些回溯

请帮助我理解这个问题。

Answer 1

我已经修复了parse_description函数：

def parse_description(description):
  '''
   there is parse function
   It is example for parsing messages like this:

   Name: John
   Phone: +100500
  '''
  fields=['name','phone']
  _dict={}
  description=description.lower()
  for line in description.split('\n'):
    for field in fields:
        if field in line:
            split_line=line.split(':')
            if len(split_line)>1:
                _dict[field]=split_line[1]
  return _dict

1. 我将fields值更改为小写，因为描述上的所有操作都在description.lower()上。
2. 在pre_dict[field]=line.split(':')[1]行上，您正在拆分行以获得结果。这已经完成了：split_line=line.split(':')，所以您可以将pre_dict行替换为pre_dict[field]=split_line[1]
3. 在同一行中，您使用的变量是pre_dict，它以前从未被引用过。我想您是想使用_dict，所以行应该是_dict[field]=split_line[1]
4. 函数返回dict，它是一种类型，而不是变量。您可能希望它返回包含字段数据的字典，因此它应该返回_dict；否则总是会得到结果<type 'dict'>

至于剩下的代码，没有足够的上下文让我理解发生了什么或哪里出了问题。至少parse_description函数现在应该可以工作了。
