在 Python 上使用 Google 搜索 API 时出现错误答案

【问题标题】：Getting Errors When Using Google Search API on Python在 Python 上使用 Google 搜索 API 时出现错误
【发布时间】：2019-08-16 22:20:21
【问题描述】：

我正在尝试在 Python 上运行 Google 搜索 API，特别是这个：https://github.com/abenassi/Google-Search-API。

当我尝试通过在 Sublime Text 3 上运行此代码来测试它时，

from google import google
num_page = 1
search_results = google.search("This is my query", num_page)
for result in search_results:
    print(result.description)

我收到很多错误，如下所示。

我需要做些什么来消除这些错误并让 Google Search API 正常工作？

标签： python python-3.x google-search-api

【解决方案1】：

fake_useragent 只是模仿用户代理而不是官方的。因此，它在检测到时会引发错误。对于最近一次丢失的通话，我做了以下操作：

pip3 install fake_useragent --upgrade
ua = UserAgent(use_cache_server = False, verify_ssl=False) #很重要的一步，经过这一步就可以写代码了
ua = UserAgent() #在我的情况下创建 UserAgent 的对象 header = {'user-agent': ua.chrome} #accessing 打印（ua.chrome）

【解决方案2】：

这不是官方 API，因此 google 可能检测到您正在抓取他们的内容“FakeUserAgentError”。尝试使用官方API（每天免费搜索 100 次）。然后试试这样 here
