###上面只是一個頁面的說說,估計寫前端移動端的要暈死,好惡心,要是返回個null或者空回來。。
上面程式碼可以直接在jsonview裡面進行格式化,
爬取的欄位是:cards 下面的mblog下面的:text ,idstr(拼接評論頁的)
這裡的id就是idstr
詳情頁就是上面評論條目的json串,搞下來也是一大把,跟上面的差不多,詳情頁裡面的資料跟評論頁的資料差不多,這裡就不再繼續多些了,因為上面的內容已經佔用的差不多了
因為微博的封IP地址的原因,所以第一次爬取了4w多資料,就GG了,第二天晚上睡眠30秒,爬取一條,發現,毛用也沒有,只好是接著爬,ip不封了之後換了cookie,換了starturl,換了page索引繼續爬取,也睡眠了10秒,反正睡多了也沒用,最後爬取的垃圾資料有22萬左右吧,去掉去重不要的估計也就4000不知道有沒有,反正也沒數。
附上幾張爬蟲過程中的圖片截圖:
最後是微博資料的結果圖片:
這裡的程式碼上傳到github上了,有需要的話可以自己去下載,另外寫了一份類似於 爬取新浪微博京東客服 @京東客服的簡單爬蟲。
發一下牢騷,json串又多又大又不穩定,返回不一致
貼上部分程式碼:

現在暫時可以借用這份程式碼,裡面的url跟cookie換一下,用自己的賬號就可以。另外爬蟲要學會用fiddler等類似的抓包工具,感覺確實是抓包利器。
公司996啊, 加上自己的能力有限,確實現在學習也就到這深度了 以後要多瞭解一下cookie池,代理池之類似的東西。
