Exploration of Baidu and Google URL encoding methods

Today I noticed that Baidu and Google have different URL encoding methods. For example, we search for the word "technology" and then observe the IE Address Bar. The result obtained by using Baidu is:Http://www.baidu.com? Wd = % BC % CA % F5 cl = 3 What is the result from Google?Http://www.google.com/search? Hl = zh-CN q = % E6 % 8A % 80% E6 % 9C % AF lr = That is, baidu_urlencode ("technology") = % BC % CA % F5, google_urlencode ("technology") = %

Python crawls Google search results

A period of time has been studying how to use Python to crawl search engine results, in the implementation of the process encountered a lot of problems, I have to record the problems I encountered, I hope to encounter the same problem of children's shoes to avoid detours. 1. Selection of search engines Choosing a good search engine means you can get more accurate search results. There are four types of search engines I've used: Google, Bing, Baidu, Yahoo! As a programmer, I prefer Google. But w
