javascript提取聯通我的信息和通話記錄的代碼

因爲一些巨大的困難,一些後端爬蟲改爲了前端爬蟲。javascript

 

前端爬蟲是隻有js語言,後端爬蟲有python java nodejs php這些語言。php

 

前端爬蟲有window.document對象,在瀏覽器端的爬蟲即便是二次發送ajax,也不須要學後端爬蟲來構造一堆請求頭,特別是困難的cookie token。最爲重要的仍是自然的突破了ip限制。css

 

提取我的信息,直接使用頁面渲染後的結構:html

提取通話記錄,這裏和上面不一樣,發送了ajax來獲取json,按月份按分頁獲取通話記錄:前端

            function extractCallRecordByPage(page) {
                var page = page || 1;

        };
        return JSON.stringify(callRecordsInfoObj);

    }

    return extractCallRecords();
}
//extractCallRecordsOuter();

  

爲了一個腳本一個函數,在最外層套了一個函數。java

有沒有很像js閉包,但這不是閉包。node

最後三行是python

    return extractCallRecords();
}
extractCallRecordsOuter();

若是改爲下面,
 return extractCallRecords;
}
extractCallRecordsOuter()();

這樣就是js之閉包了。jquery

 

 

 

前端爬蟲時候,使用jqury選擇器或者document的queryselector方法就能使用css3選擇器的語法了。比getElementByxx能更精確的提取某些元素。css3

使用jquery時候,若是被爬頁面沒有引入jquery庫,須要先在document注入jquery地址或者完整的執行一遍jquery代碼。
