Python 爬取熱詞並進行分類數據分析-[熱詞分類+目錄生成]

　　　　老師說要參照各大平台的分類，我就直接按照博客園的分類來吧（我實在看不懂那些機器學習是怎么實現的，連入門的門檻都遠遠不及）！如下圖，可以看到博客園的新聞將新聞分成了如下幾類：互聯網類、IT業界類、軟件開發類、開源類、電腦硬件類、游戲類、創業類、手機相關類、科學類、其他類。我就根據這幾類將對應類新聞里爬出來的數據進行對應類的划分。（看來又要重新爬數據了啊）

　　　　開始爬之前事先說明一下，這次改動應該是最后一次改動了，另外我發現每一類新聞都有 100 頁，這...相當於每一類都有，所以不保證有誤差的存在，另外為了減少數據量，我打算將 “頻數為15” 這一條件上升到 “頻數為20”，不然怎么爬的完？我先預算一下，今天和明天一起寫這個博客，另外明天的話，就再寫一份總結性的博客，這個小目標就算完結吧！當然最后可能會加入微信小程序部分或者APP部分，到時候再說。

　　　　根據這10類新聞，我們總共要爬取些什么數據呢？

　　　　首先，通過帶有 header 的 request 方式爬取 https://news.cnblogs.com/ 這一初始鏈接，要爬以上 10 類新聞的鏈接，再爬取類中封裝鏈接的構造，並開啟新的爬取，對應每一類數據給爬到的熱詞信息后面追加一個“熱詞類型”的標簽，這需要我們改造 KeyWords 類，向 KeyWords 類中加入 kind 屬性，改寫 __toString() 成員函數。之后改造調用過 KeyWords 類的地方。(News不需要)

　　　　關於分類頁面的構造方法：

　　　　　　首先是原新聞網址：https://news.cnblogs.com/

　　　　　　其次，以 “互聯網” 為例：https://news.cnblogs.com/n/c1101

　　　　　　然后是第 100 頁的地址：https://news.cnblogs.com/n/c1101?page=100

　　　　　　很容易的判斷到是在原網址的基礎上加入對應互聯網的 a 標簽上的 href 鏈接，需要將數據加載到一起來組成爬取鏈接！

　　　　但是爬的過程中發現了問題，就是我爬不到對應的分類鏈接，既然這樣，我只能人工地獲取它們的鏈接了，就10條數據無所謂了，本來因為懶想讓網頁幫我做的，看來是博客園讓我勤快的。哈哈哈！

　　　　對應鏈接：

　　　　　　互聯網類：https://news.cnblogs.com/n/c1101

　　　　　　IT業界類：https://news.cnblogs.com/n/c1102

　　　　　　軟件開發類：https://news.cnblogs.com/n/c1103

　　　　　　開源類：https://news.cnblogs.com/n/c1109

　　　　　　電腦硬件類：https://news.cnblogs.com/n/c1111

　　　　　　游戲類：https://news.cnblogs.com/n/c1110

　　　　　　創業類：https://news.cnblogs.com/n/c1112

　　　　　　手機相關類：https://news.cnblogs.com/n/c1113

　　　　　　科學類：https://news.cnblogs.com/n/c1114

　　　　　　其他類：https://news.cnblogs.com/n/c1199

　　　　在 Surapity 類中建立字典，存儲類型的名稱和對應鏈接。

　　　　爬取時間較長，從下午4：51到現在第2天的1：44，過程曲折且難以簡言明之。

　　　　途中遇到好幾個網站會使爬蟲程序終止，比如其他類的 Apple Watch UI動效解析，嗚哇~試一次，卡一次。程序員的痛苦莫過於此！！！

　　　　統計基礎數據共計 17469 條數據！文件大小約為 1.96 M !

　　　　現在開始制作數據表：(先修改 fileR.py)

 1 import codecs
 2 
 3 
 4 def makeSql():
 5     file_path = "../../testFile/frc/words_sql.txt"
 6     f = codecs.open(file_path, "w+", 'utf-8')
 7     f.write("")
 8     f.close()
 9 
10     fw = open("../../testFile/frc/word.txt", mode='r', encoding='utf-8')
11     tmp = fw.readlines()
12 
13     num = tmp.__len__()
14 
15     for i in range(0,num):
16         group = tmp[i].split("\t")
17         group[0] = "'" + group[0] + "'"
18         group[3] = "'" + group[3][0:group[3].__len__()-1] + "'"
19         f = codecs.open(file_path, "a+", 'utf-8')
20         f.write("Insert into words values ("+group[0]+","+group[1]+",'"+group[2]+"',"+group[3]+",'"+group[4]+"');"+"\n")
21         f.close()
22 
23 makeSql()

fileR.py

　　　　執行並按照之前的方法導入數據，這里博主因為使用電腦管家清理了一下C盤，然后 Navicat就崩掉了，真的崩了（建立不了查詢了，這個之后有解決方法的話，我再寫一期博客吧！）！所以，不搞虛的，直接用文本導入了！

　　　　建立 keywords 表（或視圖）的方法同上上期的博客，那樣獲取每一個熱詞的數量！

 1 CREATE TABLE keywords
 2 AS
 3 (
 4     SELECT 
 5         word AS word,
 6         SUM(num) AS num
 7     FROM
 8         words
 9     GROUP BY word
10     ORDER BY num 
11     DESC
12 )

CreateKeywordsTable.sql

　　　　哈哈哈哈！熱詞頻數過萬了呢！希望我的電腦還能撐住，繼續爬！（但是現在已經2點了，先定個2個小時的鬧鍾，拓撲數據讓它自己爬着）

　　　　對於 WebConnector 類，我要着重說一下，我本次爬取將此代碼注釋掉了：

# 這句話處理以后，就將帶有 “年”、“月”、“日” 字眼的語句以及之后的語句全部清除掉了，當時是旨在消除不必要的解釋部分，但現在看來沒必要！多多益善嘛！
tpl = StrSpecialDealer.ut_date(tpl)

　　　　早上醒來發現大問題——電腦自己休眠了，唉~希望自己能夠吃一塹長一智吧！

　　　　在電腦熬夜干爬蟲的時候盡力將休眠關閉，在設置中如下：

　　　　拓撲數據也完成了，大約又歷時 5 個小時，關鍵是在電腦爬蟲時我還不能用電腦干其他的（尤其是截圖軟件，運行的話，爬蟲程序一准給你崩停）

　　　　終於有完整數據了，現在我們開始數據處理！

　　　　根據不同分類將數據匯總和數據處理了（也就是說剩余沒有Python的事情了），至此熱詞分類完畢。

　　2、熱詞目錄生成

　　　　我們需要展示每一個分類的前10個數據，以此做成第一個頁面。

　　　　可以制作新的視圖，也可以直接寫大長 Sql 語句，我比較懶，就按長語句來了

ServletForKindKeyWords.java

　　　　然后制作 js 部分：

　　　　　　先顯示分類，然后利用套裝形式進行數據載入：

　　如果點擊獲取本類更多熱詞，就可以跳轉至本類頁面！

　　Like this:

　　附加新 js 代碼：
