  • 3.3 詳情的爬蟲代碼 (參考的百度的解析response的代碼舟茶，自己不太想寫了)
    def spider(page_num,hostUrl):

    main_url為要爬取的主頁地址 if page_num:

    main_url = hostUrl + '&page=' + str(page_num)

    微博的分頁機(jī)制是每頁10條微博 try:

    r = requests.get(url=main_url, headers=headers)
    r.raise_for_status()
    except Exception as e:
    print("爬取失敗", e)
    return 0 result_json = json.loads(r.content.decode('utf-8'))
    info_list = []
    for card in result_json['data']['cards']:
    info_list_sub = []
    if card.get("mblog"):
    info_list_sub.append(card['mblog']['attitudes_count']) # 獲贊數(shù) info_list_sub.append(card['mblog']['comments_count']) # 評論數(shù) info_list_sub.append(card['mblog']['reposts_count']) # 轉(zhuǎn)發(fā)數(shù) if page_num == 1:
    info_list_sub.append(card['mblog']['created_at']) # 發(fā)博時(shí)間 elif '2018' not in card['mblog']['created_at']:

  • 3.6 啟動代碼
    print("### 開始爬取微博 ")

    1堵第、封裝地址到urls中g(shù)etHostUrls()

    2、遍歷封裝好的urls隧出，循環(huán)查詢接口踏志，獲取評論數(shù)if name == 'main':

    main(10)

  • 3.7 補(bǔ)充

    • 運(yùn)行代碼的時(shí)候，需要在.py 的同級建立一個(gè)weibo.csv文件

    • 微博有反爬機(jī)制胀瞪，可以設(shè)置線程休眠

      • 代碼中是注釋的版本

      • time.sleep(random.randint(4, 6)) # 每爬取一條微博暫停4到6秒针余，防反爬
