[英]how can I transfer the javascript code to python code?
the javascript code is here: javascript代码在这里:
var goat=6111+7380;
var hen=5548+7476^goat;
var seal=2094+4451^hen;
var rat=1687+7000^seal;
var pig=3997+8240^rat;
And I want get the goat
, hen
seal
variable and so on in the python. 我想在python中获取
goat
, hen
seal
变量等。 My python code is here: 我的python代码在这里:
animals = 'var goat=6111+7380;var hen=5548+7476^goat;var seal=2094+4451^hen;var rat=1687+7000^seal;var pig=3997+8240^rat;'
[eval(item.replace('var','').strip()) for item in animals.split(';')]####here is wrong
because eval('goat=6111+7380') is wrong, so how can I make the goal is equal the 6111+7380
? 因为eval('goat = 6111 + 7380')是错误的,所以如何使目标等于
6111+7380
?
ps: thanks everyone. ps:谢谢大家。 Actually I craw a website:
http://pachong.org/
to get the proxy address and the port.But the port is generated by <script>document.write((4513^pig)+15);</script>
.And the pig
variable is generated by <script type="text/javascript">var goat=6111+7380;var hen=5548+7476^goat;var seal=2094+4451^hen;var rat=1687+7000^seal;var pig=3997+8240^rat;</script>
,but this javascript code change every time when I craw the index website.So I do not know how to get the port value. 实际上我搜寻了一个网站:
http://pachong.org/
://pachong.org/以获取代理地址和端口,但是端口是由<script>document.write((4513^pig)+15);</script>
。 pig
变量由<script type="text/javascript">var goat=6111+7380;var hen=5548+7476^goat;var seal=2094+4451^hen;var rat=1687+7000^seal;var pig=3997+8240^rat;</script>
,但是每次我检索索引网站时,此javascript代码都会更改。因此,我不知道如何获取端口值。
###resultstring is something like this '(1646^hen)+19'
def getport(resultstring):
port = eval(resultstring)
return port
proxyurl= 'http://www.pachong.org/'
try:
r = requests.get(proxyurl,timeout=60*4)
except:
print 'I can not get the date of pachong.org'
if r.status_code != 200:
print 'the status is not good. status_code is %s' % r.status_code
return
ht = BeautifulSoup(r.content)
animals = str(ht.head.find_all('script')[-1].text)
[eval(item.replace('var','').strip()) for item in animals.split(';')]###it is wrong here
table = ht.find_all('table', attrs={'class':'tb'})
if not table:
return
table = table[0]
trs = table.find_all('tr',attrs={'data-type':'high'})
tr = trs[0]
idlestring = tr.find_all('td')[5].text
idlestring = idlestring.replace('\n','').replace(' ','')
if idlestring == u'空闲':
# proxy_id += 1
ip = tr.find_all('td')[1].text
portstring = tr.find_all('td')[2].text
patt = re.compile(u'document.write\((.*?)\);')
if re.findall(patt,portstring):
resultstring = re.findall(patt,portstring)[0]
else:
continue
port = getport(resultstring)
ip_port = '%s:%s' % (ip, port)
print 'ip_port is %s' % ip_port
I don't know why you'd want to do this, but this works: 我不知道您为什么要这样做,但这可行:
for item in animals.split(';'):
exec(item.replace('var','').strip())
