当我在python shell中逐一输入命令时,用于从url下载json文件的代码运行正常。但是,当我尝试运行包含此代码的模块时,我得到:ValueError: No JSON object could be decoded
。任何想法是为什么?我运行python 2.7。代码在shell中运行,但不是从模块中运行
import urllib2
from urllib2 import Request
import json
import re
url1 = "http://www.skyscanner.net/flights/lond/nyca/130514/130525/airfares-from-london-to-new-york-in-may-2013.html"
req = Request(url1)
res = urllib2.urlopen(req)
the_page = res.read()
theText = str(the_page)
myre = re.compile(r'"SessionKey":"((([a-z0-9]+-)+)[a-z0-9]{12})"')
match = re.search(myre, theText)
print match.group(1)
url2 = "http://www.skyscanner.net/dataservices/routedate/v2.0/"+str(match.group(1))
htmltext = urllib2.urlopen(url2)
data = json.load(htmltext)
现在整个代码:
import urllib2
from urllib2 import Request, urlopen, URLError, HTTPError
import json
import re
url1 = "http://www.skyscanner.net/flights/lond/nyca/130514/130525/airfares-from-london-to-new-york-in-may-2013.html"
req = Request(url1)
res = urllib2.urlopen(req)
the_page = res.read()
theText = str(the_page)
myre = re.compile(r'"SessionKey":"((([a-z0-9]+-)+)[a-z0-9]{12})"')
match = re.search(myre, theText)
url2 = "http://www.skyscanner.net/dataservices/routedate/v2.0/%s" % str(match.group(1))
req2 = urllib2.Request(url2)
try:
response = urlopen(req2)
except HTTPError as e:
print 'The server couldn\'t fulfill the request.'
print 'Error code: ', e.code
except URLError as e:
print 'We failed to reach a server.'
print 'Reason: ', e.reason
else:
data = json.loads(response.read())
print data["SessionKey"]
这是因为你的JSON对象无法解码,即'htmltext'不是json。 – danodonovan 2013-05-02 11:43:38
但为什么它会在shell中工作呢? – maddy 2013-05-02 11:46:03
它不工作在我的shell中,对不起 – danodonovan 2013-05-02 11:48:40
