缩短的 URL 需要随机化

Question

我有以下几乎可以正常工作的代码。三个 URL 被缩短，然后放入三个不同推文的内容中，然后提交到推特。但是，每次缩短 URL 时，缩短的 URL 都是相同的。因此，推文不断被推特垃圾邮件过滤器捕获。

有没有办法随机化缩短 URL 的外观以阻止这种情况发生，或者完全使用 import tinyurl 或其他方法？

import simplejson
import httplib2
import twitter
import tinyurl

print("Python will now attempt to submit tweets to twitter...")

try:

    api = twitter.Api(consumer_key='',
                      consumer_secret='',
                      access_token_key='',
                      access_token_secret='')

    for u in tinyurl.create('http://audiotechracy.blogspot.co.uk/2014/03/reviewing-synapse-antidote-rack.html',
                        'http://audiotechracy.blogspot.co.uk/2014/03/free-guitar-patches-for-propellerhead.html',
                        'http://audiotechracy.blogspot.co.uk/2014/02/get-free-propellerhead-rock-and-metal.html',
                        ):
        print u
        linkvar1 = u
        linkvar2 = u
        linkvar3 = u

    status = api.PostUpdate("The new Synapse Antidote Rack Extension:" + linkvar1 + " #propellerhead #synapse")
    status = api.PostUpdate("Free Propellerhead guitar patches for everyone!" + linkvar2 + " #propellerhead #reason #guitar")
    status = api.PostUpdate("Free Metal and Rock drum samples!" + linkvar3 + " #propellerhead #reason)


    print("Tweets submitted successfully!")

except Exception,e:
    print str(e)    
    print("Twitter submissions have failed!!!")

谢谢

当您循环遍历tinyurl.create 的结果时，您每次都将其分配给所有三个linkvar 变量，因此当循环结束时，所有三个变量都将等于u 的最后一个值。

如果您总是要处理相同数量的 URL，您可以将它们显式分配给变量：

linkvar1, linkvar2, linkvar3 = tinyurl.create(
    'http://audiotechracy.blogspot.co.uk/2014/03/reviewing-synapse-antidote-rack.html',
    'http://audiotechracy.blogspot.co.uk/2014/03/free-guitar-patches-for-propellerhead.html',
    'http://audiotechracy.blogspot.co.uk/2014/02/get-free-propellerhead-rock-and-metal.html',
)

如果 URL 的数量可能会发生变化，那么您最好使用 list 并将您想要的结果编入索引：

linkvars = tinyurl.create(
    'http://audiotechracy.blogspot.co.uk/2014/03/reviewing-synapse-antidote-rack.html',
    'http://audiotechracy.blogspot.co.uk/2014/03/free-guitar-patches-for-propellerhead.html',
    'http://audiotechracy.blogspot.co.uk/2014/02/get-free-propellerhead-rock-and-metal.html',
)
status = api.PostUpdate("The new Synapse Antidote Rack Extension:" + linkvars[0] + " #propellerhead #synapse")
status = api.PostUpdate("Free Propellerhead guitar patches for everyone!" + linkvars[1] + " #propellerhead #reason #guitar")
