编译后的Twilio Python模块错误

Question

我编写了一个简单的程序,打开一个csv文件并在其中输入所有数字.我使用Twilio(twilio-python)作为服务提供商.我的代码作为python脚本工作正常.但是,当我编译脚本(使用py2exe)时,exe文件出错.这是我从日志文件中收到的错误....

 Traceback (most recent call last):
 File "sms.py", line 39, in <module>
 File "twilio\rest\resources\messages.pyc", line 112, in create

当我使用未编译的代码时,我没有收到此错误(如下)

  import sys #2 params --- /path/to/contact/file    --- up to 160 char msg
  import csv
  import time

  from twilio.rest import TwilioRestClient 
  ACCOUNT_SID = "**************************" 
  AUTH_TOKEN  = "**************************" 
  client = TwilioRestClient(ACCOUNT_SID, AUTH_TOKEN) 

  sys.argv.pop(0)
  contactFile = sys.argv[0]
  sys.argv.pop(0)
  msg = (' ').join(sys.argv)

  print contactFile
  print " "
  print msg

  info = []
  with open(contactFile,'rb') as csvfile:
   reader = csv.reader(csvfile, delimiter=',', quotechar='|')
        for row in reader:
        info.append(row)

  contactCount = len(info)-1

  if contactCount > 0:
     #remove first item from list because its not a value that is needed....
     info.pop(0)

   for i in info:
       print " "
       contactName = i[0]
       phoneNumber = i[1]
       print "Texting " + contactName + "... \n"
       client.messages.create(
       to=phoneNumber, 
       from_="+14782856136",
       body=msg   
       )
       time.sleep(1.5)
    else:
     print("SMSify Error \n The contact file doesn't have any contacts in it.")

对于发生了什么的任何想法？

编辑:

这是我的setup.py文件

from distutils.core import setup
import py2exe, sys, os
sys.argv.append('py2exe')
Mydata_files = [('cacert.pem', ['C:\\Python27\\Lib\\site-      
packages\\twilio\\conf\\cacert.pem'])]

setup(
   console=['sms.py'],
   data_files = Mydata_files,
   options={
              "py2exe":{
                    "bundle_files": 1,
                    "compressed": True
                }
         }
 )

Answer 1

这是因为self-signed certificate文件错过了捆绑.

这个问题requests和httplib2模块一样.

例如,如果您有一个req_example.py使用request模块命名的文件:

import requests
url = 'https://google.com/'
requests.get(url)

当你运行它python req_example.py时它可以工作,但是捆绑它时,它不起作用.

或者,如果您有一个http2_example.py使用http2模块命名的文件:

import httplib2
url = 'https://google.com/'
http = httplib2.Http()
http.request(url)

当你运行它python http2_example.py时它可以工作,但是捆绑它时,它不起作用.

要解决这个问题,您有两个选择,一个bad和一个good.

1. 禁用验证SSL证书:

   要为requests模块执行此操作:

   import requests
   url = 'https://google.com/'
   requests.get(url, verify=False)
   

   对于httplib2模块:

   import httplib2
   http = httplib2.Http(disable_ssl_certificate_validation=True)
   http.request(url)
   

2. 将self-signed certificate文件添加到包:

   对于requests模块,该文件cacert.pem位于:

   .../PythonXX/lib/site-packages/requests/cacert.pem

   对于httplib2模块是:

   .../PythonXX/lib/site-packages/httplib2/cacerts.txt

   对于它们中的每一个,您可以将其复制到项目内部(或只是地址),

   并配置setup.py包括它:

   setup(console=['temp.py'],
       # for `requests` module
       data_files=['cacert.pem'] ) # or data_files=['cacerts.txt'] ) for `httplib2`
   

   并将代码更改为使用request模块:

   import os 
   import requests 
   url = 'https://google.com/' 
   cert ='cacert.pem'
   # or os.environ['REQUESTS_CA_BUNDLE'] = cert 
   os.environ['REQUESTS_CA_BUNDLE'] = os.path.join(os.getcwd(), cert)
   requests.get(url)
   

   对于httplib2模块:

   import httplib2 
   cert = 'cacerts.txt' 
   http = httplib2.Http(ca_certs=cert) 
   http.request(url)
   

   或者,如果您的httplib2版本是0.8,您可以创建一个应该命名的文件 ca_certs_locater.py,并定义一个get返回ca_certs文件路径的函数.

   def get():
       return 'cacerts.txt'
   

好的,现在为你的错误和twilio模块,它使用 httplib2, 它的cacert.pem在:

.../twilio/conf/cacert.pem

因此,您需要setup.py如上所述添加此文件.

但是twilio它本身有一个名为get_cert_file的函数,它将ca_cert文件传递给httplib2.

我想如果你使用ca_certs_locater.py上面描述的那个,它也适用于那个,但如果没有,你还有一个ugly选项,所以你可以猴子补丁get_cert_file功能twilio:

from twilio.rest.resources.base import get_cert_file
get_cert_file = lambda: 'cacert.pem'

请注意,这可能是一个问题,twilio甚至是py2exe或PyInstaller.
