当我在本地运行脚本时，我的脚本执行完美，但是当我在Python Anywhere上执行它时，它会抛出以下错误：

Traceback (most recent call last):

现在，我已经在Stack Overflow和Python本身的论坛上进行了梳理，而且我发现的解决方案都没有成功。一个建议是脚本不起作用，因为我试图访问的网站不在白名单上，而事实并非如此。我尝试使用我发现的一些代码强制PA使用不同的代理，如网站开发人员所建议的那样，但是没有用。我也看到开发人员建议有这个问题的人使用Python 2.7。我这样做了，但仍然没有改变。还有其他可能的解决方案吗？提前致谢！我的代码如下。

from twilio.rest import TwilioRestClient
from datetime import *
import urllib.request
from bs4 import BeautifulSoup
from random import randint
import ast
#use julian date to calculate days left till summer

# put your own credentials here
def dateelle():
    #use datetime to state date in Month Day, Year format.
    todaylist = date.today().timetuple()
    monthdict = {1:"January ", 2:"February ", 3:"March ", 4:"April ", 5:"May ", 6:"June ", 7:"July ", 8:"August ", 9:"September ", 10:"October ", 11:"November ", 12:"December "}
    month = monthdict[todaylist[1]]
    day = todaylist[2]
    year = todaylist[0]
    ultidate = str(month) + str(day) + ", " + str(year) + " "
    return ultidate
def temple():
    url = 'http://api.openweathermap.org/data/2.5/weather?id=5429522&APPID=0f25c0515e643bc2427f665f88a4d3eb'
    headers = {}
    headers['User-Agent'] = 'Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.112 Safari/537.36'
    tri1 = urllib.request.Request(url, headers=headers)
    tri2 = urllib.request.urlopen(tri1)
    quell = BeautifulSoup(tri2)
    tagwithtemp = int(ast.literal_eval(quell.text)['main']['temp'] * (9/5) - 459.67)
    return tagwithtemp

def daysleft():
    todayy = date.today().timetuple()[7]
    allthatremains = 147 - todayy
    return allthatremains


comp = {0:" You look nice today.",
        1:" Have a good day.",
        2:" Today will be a great day.",
        3:" You are an important person who means much to the world.",
        4: " Someone's day today will be brightened by your presence.",
        5: " Despite the amount of people in the world, your existence matters. :)",
        6: " There may be billions of people on this planet, but you still make a difference."}
billiam = "Good morning! Today is " + dateelle() + "and it is " + str(temple()) + " degrees." + comp[randint(0,6)] + " " + str(daysleft()) + " days left until summer!"

def asendoff():
    global billiam
    ACCOUNT_SID = "***" #the SID, AUTH token, and my phone number are censored
    AUTH_TOKEN = "***"
    nummer = ["***"]
    client = TwilioRestClient(ACCOUNT_SID, AUTH_TOKEN)

    for lexis in nummer:
        client.messages.create(
            to=lexis,
            from_="+15026255861",
            body=billiam,
        )

if date.today().timetuple()[6] != 6 and date.today().timetuple()[6] != 7:
    asendoff()
else:
    pass

Answer 1

代理来自PythonAnywhere免费帐户的所有外部连接以防止滥用。

您需要为此连接设置代理：

from twilio.rest.resources import Connection
from twilio.rest.resources.connection import PROXY_TYPE_HTTP

Connection.set_proxy_info(
    "proxy.server",
    3128,
    proxy_type=PROXY_TYPE_HTTP
)

但是，在Python 3中，httplib2（以及twilio-python）忽略代理设置（请参阅this page的底部），因此尝试直接连接到被阻止的Twilio。

Answer 2

Twilio开发者传道者在这里。

有previous reports表示PA有旧版本的库。几个月前，我们在库和API中设置了pretty significant change来强制执行SSL。

如果您使用的是最新版本的库，则不应对您进行任何更改。从您发布的错误中，我无法确切地知道PA正在使用哪个版本的库，但是进一步挖掘，用户似乎suggest you need a proxy。

我的建议是略微改变你的方法，也许将其部署到Heroku（它是免费的，你将能够使用你想要的确切库版本）。这样，如果您发现它在那里工作，您可以联系PA并检查他们拥有哪个库版本，您将能够告诉他们是否需要更新。

希望这有助于你

为什么我的使用twilio的脚本在本地完美运行，但在Python Anywhere上抛出错误？
