执行谷歌搜索并返回结果数量 [英] perform a google search and return the number of results

问题描述

Google Web搜索API似乎已经死亡（旧的SOAP和新的AJAX）。有没有快速搜索Google的字符串并返回结果数量？我假设我只需要进行搜索并搜索结果，但我很想知道是否有更好的方法。

The Google Web Search APIs appear to be dead (both the old SOAP and the newer AJAX). Is there a quick way to search Google for a string and return the number of results? I assume I just have to run the search and scrape the results, but I'd love to know if there's a better way.

更新：事实证明，任何不使用新API的Google自动访问 https://developers.google.com/custom-search/json-api/v1/overview 违反了他们的服务条款，因此不推荐。

Update: It turns out that any automated access to Google that doesn't use their new API https://developers.google.com/custom-search/json-api/v1/overview violates their terms of service, and is thus not recommended.

推荐答案

仍有一个免费的API ，但这里是一个屏幕刮刀：

There is still a free API, but here is a screen-scraper:

import requests
from bs4 import BeautifulSoup
import argparse

parser = argparse.ArgumentParser(description='Get Google Count.')
parser.add_argument('word', help='word to count')
args = parser.parse_args()

r = requests.get('http://www.google.com/search',
                 params={'q':'"'+args.word+'"',
                         "tbs":"li:1"}
                )

soup = BeautifulSoup(r.text)
print soup.find('div',{'id':'resultStats'}).text

结果：

$ python g.py jones
About 223,000,000 results
$ python g.py smith
About 325,000,000 results
$ python g.py 'smith and jones'
About 54,200,000 results
$ python g.py 'alias smith and jones'
About 181,000 results
