当我通过终端 m 运行我的 python 代码时,出现此错误:
def GPlag(text,encode=False):
import urllib, urllib2, json
if encode == True:
text = text.encode('utf-8')
query = urllib.quote_plus(text)
base_url = 'http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q='
url = base_url + '%22' + query + '%22'
request = urllib2.Request(url,None)
response = urllib2.urlopen(request)
result = json.load(response)
output = []
if result['responseData']['results'] != []:
firstMatch = result['responseData']['results'][0]
output.append(firstMatch['title'])
output.append(firstMatch['visibleUrl'])
output.append(firstMatch['content'])
return output
def callGPlag(n):
for s in n:
outcome = GPlag(s,encode=True)
它给;
TypeError: 'NoneType' object has no attribute '__getitem__'
在这一if result['responseData']['results']
行。这是回溯:
Traceback (most recent call last):
... in <module> GPlagFile(sys.argv[1])
... in GPlagFile outcome = GPlag(s,encode=True)
... in GPlag if 'results' in result['responseData']:
TypeError: argument of type 'NoneType' is not iterable
