Question

我试图在脚本下面运行：

import urllib
import json as m_json
query = raw_input ( 'Query: ' )
query = urllib.urlencode ( { 'q' : query } )
response = urllib.urlopen ( 'http://ajax.googleapis.com/ajax/services/search/web?v=1.0&' + query ).read()
json = m_json.loads ( response )
results = json [ 'responseData' ] [ 'results' ]
for result in results:
    title = result['title']
    url = result['url']   # was URL in the original and that threw a name error exception
    print ( title + '; ' + url )

我的输出是：

Query: test
Traceback (most recent call last):
  File "test.py", line 7, in <module>
    results = json [ 'responseData' ] [ 'results' ]
TypeError: 'NoneType' object has no attribute '__getitem__'

Answer 1

使用以下代码打印出原始json后：

print(str(json))

我们从谷歌获得以下回复：

{'responseData': None, 'responseDetails': 'The Google Web Search API is no longer available. Please migrate to the Google Custom Search API (https://developers.google.com/custom-search/)', 'responseStatus': 403}

可在此处找到解决方案：

What are the alternatives now that the Google web search API has been deprecated?

Answer 2

您可以打印结果，您将看到以下内容：

Google Web Search API不再可用。请迁移到Google自定义搜索API（https://developers.google.com/custom-search/）

试试;）祝你好运
