How to parse Google custom search javascript output in python?-CodePudding

I am trying to fetch some articles from

How can I get articles along with their link from the js object in python?

CodePudding user response：

response.text gives you string and if you remove /*O_o*/\ngoogle.search.cse.api12760( at the beginning, and ); at the end then you will have normal JSON which you can convert to Python dictionary using json.loads() - and then you can use [key] to get data from dictionary.

Minimal working example

import requests
import json

params = (
    ('rsz', 'filtered_cse'),
    ('num', '10'),
    ('hl', 'en'),
    ('source', 'gcsc'),
    ('gss', '.com'),
    ('cselibv', 'cc267ab8871224bd'),
    ('cx', '000299513257099441687:fkkgoogvtaw'),
    ('q', 'multi-label text classification'),
    ('safe', 'off'),
    ('cse_tok', 'AJvRUv1dd6NHqw5GKAoRSg3lLILE:1636278007905'),
    ('sort', ''),
    ('exp', 'csqr,cc,4618906'),
    ('callback', 'google.search.cse.api12760'),
)

response = requests.get('https://cse.google.com/cse/element/v1', params=params)

start = len('''/*O_o*/
google.search.cse.api12760(''')
end = len(');')

text = response.text[start:-end]
data = json.loads(text)

#print(data)

for item in data['results']:
    #print('keys:', item.keys())
    print('title:', item['title'])
    print('url:', item['url'])
    #print('content:', item['content'])
    #print('title:', item['titleNoFormatting'])
    #meta = item['richSnippet']['metatags']
    #if 'author' in meta:
    #    print('author:', meta['author'])
    print('---')

Result:

BTW:

If you display item.keys() then you should see what else you can get:

'cacheUrl', 'clicktrackUrl', 'content', 'contentNoFormatting', 
'title', 'titleNoFormatting', 'formattedUrl', 'unescapedUrl', 'url', 
'visibleUrl', 'richSnippet', 'breadcrumbUrl'

Or you can use for-loop to display all keys and values

for item in data['results']:
    for key, value in item.items():
        print(f'{key}: {value}')
        print('---')
    print('===================================')

Some of them may have sub dictionaries - like item['richSnippet']['metatags']['author']
