光學字符識別（OCR）是從圖像中抽取文本的工具，可以應用於公安、電信、物流、金融等諸多行業，例如識別車牌，身份證掃描識別、名片信息提取等。在爬蟲開發中，如果遭遇了有文字驗證碼的表單，就可以利用OCR來進行驗證碼處理。Tesseract-OCR引擎最初是由惠普公司開發的光學字符識別係統，目前發布在Github上，由Google贊助開發。 22 | 23 |

Scrapy爬蟲框架分布式實現 2 | 3 | ### 分布式爬蟲原理 4 | 5 | 6 | 7 | ### Scrapy分布式實現 8 | 9 | 1. 安裝Scrapy-Redis。 10 | 2. 配置Redis服務器。 11 | 3. 修改配置文件。 12 | - SCHEDULER = 'scrapy_redis.scheduler.Scheduler' 13 | - DUPEFILTER_CLASS = 'scrapy_redis.dupefilter.RFPDupeFilter' 14 | - REDIS_HOST = '1.2.3.4' 15 | - REDIS_PORT = 6379 16 | - REDIS_PASSWORD = '1qaz2wsx' 17 | - SCHEDULER_QUEUE_CLASS = 'scrapy_redis.queue.FifoQueue' 18 | - SCHEDULER_PERSIST = True（通過持久化支持接續爬取） 19 | - SCHEDULER_FLUSH_ON_START = True（每次啓動時重新爬取） 20 | 21 | ### Scrapyd分布式部署 22 | 23 | 1. 安裝Scrapyd 24 | 2. 修改配置文件 25 | - mkdir /etc/scrapyd 26 | - vim /etc/scrapyd/scrapyd.conf 27 | 3. 安裝Scrapyd-Client 28 | - 將項目打包成Egg文件。 29 | - 將打包的Egg文件通過addversion.json接口部署到Scrapyd上。 30 | 31 | -------------------------------------------------------------------------------- /Day66-75/Scrapy爬蟲框架高級應用.md: -------------------------------------------------------------------------------- 1 | ## Scrapy爬蟲框架高級應用 2 | 3 | ### Spider的用法 4 | 5 | 在Scrapy框架中，我們自定義的蜘蛛都繼承自scrapy.spiders.Spider，這個類有一係列的屬性和方法，具體如下所示： 6 | 7 | 1. name：爬蟲的名字。 8 | 2. allowed_domains：允許爬取的域名，不在此範圍的鏈接不會被跟進爬取。 9 | 3. start_urls：起始URL列表，當我們沒有重寫start_requests()方法時，就會從這個列表開始爬取。 10 | 4. custom_settings：用來存放蜘蛛專屬配置的字典，這裏的設置會覆蓋全局的設置。 11 | 5. crawler：由from_crawler()方法設置的和蜘蛛對應的Crawler對象，Crawler對象包含了很多項目組件，利用它我們可以獲取項目的配置信息，如調用crawler.settings.get()方法。 12 | 6. settings：用來獲取爬蟲全局設置的變量。 13 | 7. start_requests()：此方法用於生成初始請求，它返回一個可疊代對象。該方法默認是使用GET請求訪問起始URL，如果起始URL需要使用POST請求來訪問就必須重寫這個方法。 14 | 8. parse()：當Response沒有指定回調函數時，該方法就會被調用，它負責處理Response對象並返回結果，從中提取出需要的數據和後續的請求，該方法需要返回類型爲Request或Item的可疊代對象（生成器當前也包含在其中，因此根據實際需要可以用return或yield來産生返回值）。 15 | 9. closed()：當蜘蛛關閉時，該方法會被調用，通常用來做一些釋放資源的善後操作。 16 | 17 | ### 中間件的應用 18 | 19 | #### 下載中間件 20 | 21 | 22 | 23 | #### 蜘蛛中間件 24 | 25 | 26 | 27 | ### Scrapy對接Selenium 28 | 29 | 30 | 31 | ### Scrapy部署到Docker 32 | 33 |
