java+selenium, python+selenium瀏覽界面,滑動頁面

用到selenium的時候,有時須要滑動屏幕,模擬瀏覽,這時候就能夠用到下邊的代碼了:

首先是java的selenium滑屏代碼(不知道爲啥後邊就亂了排版,本身調整下就好~)

private static Random random = new Random();

private void pretendScrolling(JavascriptExecutor js, int sum) throws InterruptedException {
 sum--;
 int step;
 int length;
 switch (sum) {
 case 0:
 step = random.nextInt(30) + 1 + 50;
 length = random.nextInt(3000) + 1 + 3000;
 smoothlyScrolling(js, 0, step, length, true);
 smoothlyScrolling(js, 0, step, length, false);

 smoothlyScrolling(js, 0, step, length, true);
 smoothlyScrolling(js, length, step, 8000, true);

 step = random.nextInt(20) + 1 + 80;
 smoothlyScrolling(js, 0, step, 8000, false);

 length = random.nextInt(2000) + 1 + 3000;
 smoothlyScrolling(js, 0, step, length, true);
 smoothlyScrolling(js, 0, 20, length, false);
 break;
 case 1:
 step = random.nextInt(10) + 1 + 40;
 smoothlyScrolling(js, 0, step, 6000, true);
 Thread.sleep(3000);
 smoothlyScrolling(js, 0, step, 6000, false);

 length = random.nextInt(1500) + 1 + 1000;
 step = random.nextInt(10) + 1 + 40;
 Thread.sleep(3000);
 smoothlyScrolling(js, 0, step, length, true);
 Thread.sleep(5000);
 step = random.nextInt(10) + 1 + 40;
 smoothlyScrolling(js, length, step, 7000, true);
 Thread.sleep(3000);

 step = random.nextInt(20) + 1 + 80;
 smoothlyScrolling(js, 0, step, 8000, false);
 Thread.sleep(3000);
 break;
 case 2:
 step = random.nextInt(10) + 1 + 30;
 length = random.nextInt(1300) + 1 + 1000;
 smoothlyScrolling(js, 0, step, length, true); Thread.sleep(8000); step = random.nextInt(10) + 1 + 20; smoothlyScrolling(js, length, step, 6000, true); Thread.sleep(3000); length = random.nextInt(1500) + 1 + 1500; step = random.nextInt(20) + 1 + 40; smoothlyScrolling(js, length, step, 6000, false); Thread.sleep(3000); step = random.nextInt(30) + 1 + 70;
 smoothlyScrolling(js, length, step, 6000, true);
 Thread.sleep(4000);
 step = random.nextInt(20) + 1 + 30;
 smoothlyScrolling(js, 0, step, 6000, false);
 Thread.sleep(3000);
 break;
 case 3:
 step = random.nextInt(10) + 1 + 30;
 smoothlyScrolling(js, 0, step, 7000, true);
 Thread.sleep(3000);
 step = random.nextInt(30) + 1 + 20;
 smoothlyScrolling(js, 0, step, 7000, false);
 Thread.sleep(3000);
 break;
 case 4:
 step = random.nextInt(10) + 1 + 50;
 smoothlyScrolling(js, 0, step, 7000, true);
 Thread.sleep(3000);
 length = random.nextInt(1500) + 1 + 2000;
 step = random.nextInt(25) + 1 + 20;
 smoothlyScrolling(js, length, step, 7000, false);
 Thread.sleep(3000);
 step = random.nextInt(20) + 1 + 30;
 smoothlyScrolling(js, length, step, 7000, true);
 Thread.sleep(3000);
 step = random.nextInt(20) + 1 + 40;
 smoothlyScrolling(js, 0, step, 7000, false);
 Thread.sleep(2000);
 break;
 case 5:
 step = random.nextInt(20) + 1 + 30;
 smoothlyScrolling(js, 0, step, 2500, true);
 Thread.sleep(3000);
 step = random.nextInt(30) + 1 + 40; 
 smoothlyScrolling(js, 0, step, 2500, false);
 Thread.sleep(3000);
 step = random.nextInt(20) + 1 + 30;
 smoothlyScrolling(js, 0, step, 7000, true);
 Thread.sleep(6000);
 step = random.nextInt(20) + 1 + 30;
 smoothlyScrolling(js, 0, step, 7000, false);
 Thread.sleep(2000);
 break;
 default:
 case 6:
 step = random.nextInt(30) + 1 + 30;
 length = random.nextInt(1500) + 1 + 2500;
 smoothlyScrolling(js, 0, step, length, true);
 step = random.nextInt(30) + 1 + 70;
 smoothlyScrolling(js, 0, step, length, false);
 step = random.nextInt(20) + 1 + 40;
 smoothlyScrolling(js, 0, step, 7000, true);
 step = random.nextInt(25) + 1 + 20;
 smoothlyScrolling(js, 0, step, 7000, false);
 Thread.sleep(3000);
 step = random.nextInt(25) + 1 + 20;
 length = random.nextInt(1500) + 1 + 3000;
 smoothlyScrolling(js, 0, step, length, true);
 Thread.sleep(3000);
 step = random.nextInt(15) + 1 + 30;
 smoothlyScrolling(js, 0, step, length, false);
 break;
 }
}

private void smoothlyScrolling(JavascriptExecutor js, int floor, int step, int celling, boolean direction) {
 if (direction) {
 for (int i = floor; i <= celling; i += step) {
 js.executeScript("scrollTo(0," + i + ")");
 }
 } else {
 for (int i = celling; i >= floor; i -= step) {
 js.executeScript("scrollTo(0," + i + ")");
 }
 }
}

用法以下:



兩個參數,其中js表示的是driver, sum是一個隨機數,表示隨機的從7中瀏覽方式之間選一種


再而後是在python selenium中的應用,我專門寫了一個類出來存放瀏覽界面的代碼,而後在須要用到它的地方導入,引用

import random
import time

 pass



#(不知道爲啥會亂排版,這是另外一個方法)def smoothlyScrolling(driver, floor, step, celling, direction):
 if direction is True:
 i = floor
 while i <= celling:
 i += step
 jscript = "window.scrollTo(1, {height_i})".format(height_i=i)
 driver.execute_script(jscript)
 else:
 i = celling
 while i >= floor:
 i -= step
 jscript = "window.scrollTo(1, {height_i})".format(height_i=i)
 driver.execute_script(jscript)

 

在python的其它類中引用以下:
首先先在相關類中引入滾動界面的類

 

而後調用:

以上就是selenium裏邊滑動界面的一組方法了,支持java和python.

 

由於圖片好像沒有加載出來,因此再放一下.而後也不知道爲啥排版會亂,要用的話本身調整一下便可.
