菜鳥爬取中關(guān)村手機(jī)詳情頁參數(shù)及報(bào)價(jià)

背景介紹：

• 需求是爬取所有手機(jī)詳情頁各個(gè)手機(jī)型號(hào)對(duì)應(yīng)的價(jià)位區(qū)間及參數(shù)；
• 此前沒有爬蟲經(jīng)歷，套用網(wǎng)上教程屢屢報(bào)錯(cuò)，痛定思痛決定自己搜索爬蟲框架，參照官方文檔并整理網(wǎng)頁源碼規(guī)則，制定適合自己的爬取方案；
• 網(wǎng)上的爬蟲框架有scrapy和bs4，個(gè)人覺得bs4較易上手，也能滿足本次爬取需求，所以選擇了bs4;
• 感興趣的筒子可以研究下scrapy哦，貌似遞歸爬取很強(qiáng)大的趕腳；
• 廢話不多說，下面開始爬取吧~

---

方案很簡單，主要分三步：

• 觀察列表頁和詳情頁之間的關(guān)系后發(fā)現(xiàn)，列表頁中 /cell_phone/index375437.shtml 的數(shù)字對(duì)應(yīng)詳情頁url中的數(shù)字，由此聯(lián)想到，可以把這個(gè)數(shù)字摳出來作為商品id，放入詳情頁url中，由此獲取詳情頁鏈接 http://detail.zol.com.cn/cell_phone/index375437.shtml ；
• 結(jié)果數(shù)據(jù)：
• 第一步，爬取列表頁所有的商品id（觀察網(wǎng)頁后發(fā)現(xiàn)，前104頁包含了所有有效商品id，104頁之后均為空，可以寫for循環(huán)獲取前104頁的所有商品id）；
• 第二步，將所有商品id帶入詳情頁url獲取所有詳情頁鏈接 ;
• 第三步，同樣循環(huán)獲取所有詳情頁源代碼，并解析出需要的字段存到csv上。
  備注:當(dāng)然啦，中間涉及要一些調(diào)試和解析的過程，是比較費(fèi)神的，好在都已經(jīng)解決。
  這里獲取的詳情字段為16個(gè)（標(biāo)題、手機(jī)大類名（比如中興）、中文名稱、別名（含英文名稱）、上市時(shí)間、屏幕尺寸、商家指導(dǎo)價(jià)、價(jià)格區(qū)間、運(yùn)行內(nèi)存、存儲(chǔ)內(nèi)存、內(nèi)核、主屏幕、前置攝像頭、后置攝像頭、電容、電池類型）+1個(gè)（詳情頁url，方便對(duì)照）：

參考網(wǎng)址

下面就奉上爬取代碼啦！為了方便測試，最后還有爬取其中一個(gè)網(wǎng)頁的測試代碼哦~
建議對(duì)照網(wǎng)頁源碼，更易于理解解析過程。參考網(wǎng)址：
